Description:
LIGHTING DEVICE AND LIGHTING ASSEMBLY AND REGULATING DEVICE

TECHNICAL FIELD

[0001] Embodiments of the present invention relate to a lighting device, and in particular, to an a lighting device for regulating a light intensity and/or a light color.

BACKGROUND OF THE INVENTION

[0002] A LED (Light Emitting Diode) is a solid semiconductor device that can convert electric energy into visible light. The LED becomes an ideal light source that takes the place of conventional light sources due to advantages of small volume, low power consumption, long service life, high brightness, low heat quantity, environmentally friendly, durability, and the like. LEDs are applied quite flexibly, and may be made into short thin products in various forms of points, lines, and planes. The LED may be controlled conveniently, and the light intensity and/or color of light may be regulated at will only by adjusting a current. LEDs have different light color configurations, and various light color effects may be achieved by adjusting light intensities of LEDs with different light colors. LEDs have been widely applied to various types of lighting devices, such as a battery-powered flashlight, a mini-sized sound control lamp, a safety flare, illuminating lamps for roadways and indoor stairs, and building and marker continuous lighting lamps.

[0003] However, in most cases, a single type of lighting device cannot meet diversified demands of consumers. On the one hand, for example, when a consumer hopes to implement a light intensity and/or light color tuning function after purchasing a lighting device with a common lighting function, it is necessary to replace the lighting device, so a purchase cost increases. On the other hand, in order to meet the diversified demands of consumers for lighting devices, a factory has to produce various types of lighting devices in batches. In this case, the factory needs to correspondingly open various types of production lines, thereby resulting in an increase in production cost. Therefore, lowering the batch production cost for the factory and the purchase cost for consumers so that a lighting device may selectively meet the demand for lighting in which the light intensity and light color are not tunable and a demand for lighting in which the light intensity and/or light color are tunable, has become a problem that needs to be addressed.

[0004] Therefore, it is necessary to provide an improved lighting device to solve the foregoing technical problem.

BRIEF SUMMARY OF THE INVENTION

[0005] One or more aspects of embodiments of the invention are summarized to facilitate a basic understanding of the present invention, where the brief summary of the present invention is an overview, and is not intended to identify all elements of the present invention. The main purpose of the brief summary of the invention is to present some concepts of embodiments of the present invention in a simplified form before a more detailed description is presented below.

[0006] An aspect of the present invention provides a lighting device including a lighting assembly and a regulating card. The lighting assembly includes: an illumination module; a driving circuit coupled with the illumination module, for providing a corresponding power to the illumination module after powered on; and a port comprising a first signal terminal, wherein the driving circuit is configured to receive a regulating signal via the first signal terminal for regulating the power provided to the illumination module. The regulating card is selectively inserted into the port and the regulating card comprises a second signal terminal, when the regulating card is inserted into the port, the first signal terminal is electrically coupled to the second signal terminal, the regulating card is configured to receive an external control signal and generate a regulating signal transmitted to the second signal terminal.

[0007] Another aspect of the present invention provides a lighting assembly including: an illumination module; a driving circuit coupled with the illumination module, for providing a corresponding power to the illumination module; and a port configured to selectively

accommodate a regulating card. The driving circuit is configured to receive a regulating signal out from the regulating card via the port, for regulating the power provided to the illumination module.

[0008] Another aspect of the present invention provides regulating card applied to a lighting assembly. The lighting assembly including: an illumination module; a driving circuit coupled with the illumination module, for providing a corresponding power to the illumination module; and a port configured to selectively accommodate a regulating card. The driving circuit is configured to receive a regulating signal out from the regulating card via the port, for regulating the power provided to the illumination module, the regulating card is selectively inserted into the port, the port is electrically coupled to the regulating card when the regulating card is inserted into the port, the regulating card is configured to receive an external control signal and generate a regulating signal for providing to the driving circuit via the port.

[0009] Embodiments of the present invention adopt the solution that a port is arranged on an lighting assembly, a regulating card may be selectively inserted into the port, and when the regulating card is not inserted into the port, the lighting assembly may be used for common illumination, that is, the light intensity and/or the light color are/is not tunable. When the regulating card is inserted into the port, the lighting assembly may implement a light intensity and/or color of light tuning function. Therefore, a set of lighting devices is adopted, and demands of consumers for different light sources can be met only by selectively installing a regulating card. A factory only needs to have one type of production line, so that the batch production cost of the factory is lowered. The consumers need only purchase the lighting assembly of the lighting device of embodiments of the present invention as needed, or purchase both the lighting assembly and the regulating card, so that the consumers are provided with more choices.

It should be noted that, in order to facilitate a concise description of implementations of the present invention, it is impossible to describe all features of an actual implementation in detail. It should be understood that, in an actual implementation process of any implementation, as in a process of any one project or design project, in order to achieve the developers' specific goals, and in order to meet system-related or business-related limitations, various specific decisions are usually made, and the decisions may change from one embodiment to another embodiment. In addition, it can also be understood that, although efforts made in the development process may be complicated and lengthy, for a person of ordinary skill in the art related to the content disclosed in the present invention, some changes, such as in design, manufacturing, or production, made based on the technical content disclosed in the disclosure are common technical means, and need not be disclosed herein.

[0020] FIG. 1 is a schematic diagram of a lighting device 100 according to an

implementation of the present invention. The lighting device 100 includes a lighting assembly 111. The lighting assembly 111 may implement a common lighting function. That is, after the lighting assembly 111 is powered up, the light intensity and the color of light of the lighting assembly 111 are fixed, namely, are not tunable.

[0021] In order to enable the lighting device 100 to selectively implement a light intensity or color of light tuning function, as shown in FIG. 1, in this implementation, the lighting device 100 further includes a regulating card 153 that can be freely attached or detached from the lighting assembly 111. The lighting assembly 111 is provided with a port 150, and the port 150 is configured to accommodate the regulating card 153. When the regulating card 153 is inserted into the port 150, the regulating card 153 outputs a regulating signal according to an external control signal, and then transmits the regulating signal to a driving circuit (not shown in FIG. 1) of the lighting assembly 111, so as to regulate the light intensity and/or color of light of the lighting assembly 111.

[0022] Therefore, when only a common lighting function of the lighting device 100 is required, it is merely necessary for a consumer to purchase the lighting assembly 111 in the lighting device 100 rather than the whole device, so the purchase cost is lower. If the light intensity and/or color of light tuning function needs to be added later, it is merely necessary to separately purchase a supporting regulating card 153 without the overall replacement of the lighting device. Further, for production, it is merely required to respectively produce the lighting assembly 111 and the regulating card 153 in the lighting device 100 according to market demand, so that a production process may be simplified, and it is unnecessary to produce different types of lighting devices on a large scale.

[0023] The following describes the structures and functions of the lighting assembly 111 and the regulating card 153 in detail with reference to FIGs. 2-7.

[0024] FIG. 2 is a schematic circuit diagram of a lighting device 100 according to an implementation of the present invention. The lighting device 100 has a light intensity tuning function. The lighting device 100 includes a lighting assembly 111 and a regulating card 153. As an example, the lighting assembly 111 includes a lamp holder 117, an illumination module 120, and a driving circuit 121. In some implementations, the lighting assembly 111 further includes other elements that are not shown, such as a filter or an amplifier.

[0025] In some implementations, when the lamp holder 117 is installed on a supporting lamp base (not shown), the lighting assembly 111 and an external power supply are electrically coupled, so as to power up and operate the driving circuit 121. In another implementation, in addition to the lamp base, the lighting assembly 111 may also be electrically connected to an external power supply via a wire, so as to power up and operate the driving circuit 121. After being powered up, the driving circuit 121 receives a first power provided by the external power supply, to provide power for the illumination module 120.

[0026] In this implementation, the illumination module 120 is an LED array. In another implementation, the illumination module 120 may further include other types of lamps. When the first power does not match the power required by the LED array 120, the driving circuit 121 includes a converter 123, for converting the first power into a second power that is matches with the LED array 120 and providing the second power to the LED array 120. When the first power matches the power required by the LED array, the first power may be provided to the LED array 120.

[0027] More specifically, when the first power is an alternating current, such as a 220 V alternating current, the converter 123 is an AC-DC converter. The AC-DC converter 123 is configured to convert the alternating current into a direct current, such as a 50 V direct current. When the first power is a direct current, such as a 100 V direct current, the converter 123 is a DC-DC converter. The DC-DC converter 123 is configured to convert the 100 V direct current into a 50 V direct current. When the first power is a direct current and exactly matches the LED array 120, for example a 50 V direct current, the converter 123 may be removed.

[0028] After the lighting assembly 111 is powered up, the LED array 120 illuminates. In this case, the light intensity is not tunable. In order to implement the light intensity tuning function, the driving circuit 121 further includes a dimming module 125. Assuming that the first power is an alternating current, the dimming module 125 is connected between the AC/DC converter 123 and the LED array 120. Without the control of the regulating signal, the dimming module 125 provides the second power for the LED array 120.

[0029] In some implementations of the present invention, the port 150 is arranged on a housing of the lighting assembly 111 to accommodate the regulating card 153. In some implementations, the port 150 is arranged on a radiator (see FIG. 1) of the lighting assembly 111. In another implementation, the port 150 may be arranged on another suitable position of the housing of the lighting assembly 111. When the lighting assembly 111 need to implement the light intensity tuning function, the regulating card 153 is installed in the port 150 by using a card tray 152 or the regulating card 153 is directly inserted into the port 150.

[0030] In some implementations, the regulating card 153 may be in the form of an SD card, a USB card, a SIM card, or another type of communication card. Correspondingly, the port 150 may be a SD card port, a USB card port, a SIM card port, or another communication port. In another implementation, in addition to the structure of a card, the regulating card 153 may be in the form of another structure, such as a cylinder. Correspondingly, the port 150 may be arranged in a supporting form, which is capable of accommodating the regulating card 153.

[0031] In some implementations, the regulating card 153 may be provided with a power supply module, such as a battery or an integrated power supply module, for providing the power required by the regulating card 153. In another implementation, the regulating card 153 may be provided with the required power by the driving circuit 121.

[0032] When the power required by the regulating card 153 is provided by the driving circuit 121, the driving circuit 121 further includes a voltage converter 127, which is connected to a power supply terminal of the port 150, via output terminals 128 and 129, to provide the port 150 with a port voltage. When the regulating card 153 is inserted into the port 150, the port voltage provides the power required by the regulating card 153.

[0033] In an implementation, an input end of the voltage converter 127 is connected to an output end of the converter 123, to use a portion of the power as the port voltage. In another implementation, the input end of the voltage converter 127 may be connected to the lamp holder 117, or connected to an output end of the dimming module 125, to use a portion of the power as the port voltage.

[0034] The port 150 includes a first signal terminal 1501, and the regulating card 153 includes a second signal terminal 157 (see FIG. 3). When the regulating card 153 is inserted into the port 150, the first signal terminal 1501 and the second signal terminal 157 are electrically coupled. The "electrically coupled" used herein may include coupling forms such as electric coupling, electromagnetic coupling, optical coupling and/or photoelectric coupling, for implementing signal transmission.

[0035] The regulating signal generated by the regulating card 153 may be transmitted to the second signal terminal 157 via the first signal terminal 1501, and provided to the dimming module 125 in the driving circuit 121. The power provided for the LED array 120 may be regulated by adjusting a voltage, a current and/or a power output by the dimming module 125, so as to regulate a light intensity of the LED array 120.

[0036] FIGs. 3-5 are schematic circuit diagrams of the regulating card 153 shown in FIG. 2 according to different implementations. When the regulating card 153 is inserted into the port 150, the regulating card 153 is configured to receive an external control signal to output a regulating signal, and transmit the regulating signal to the driving circuit 121 of the lighting assembly 111 , so as to regulate the light intensity of the lighting assembly 111.

[0037] Referring to FIG. 3, in this implementation, an external remote-controller 191 is configured to provide a wireless control signal 193, which is used as the external control signal. The external remote-controller 191 may include a smart apparatus, such as a smart phone or a smart tablet computer. The external remote-controller 191 may further include a control device, such as a remote control, which is designed to support the regulating card 153.

[0038] The wireless control signal 193 is described by taking a smart phone 191 as an example. A supporting application program or module and a visual interface are installed on the smart phone 191, so that a user may select a required light intensity between 0% and 100%, and send the wireless control signal 193 via the smart phone 191. In another implementation, a button for hierarchically regulating the light intensity is arranged on the smart phone 191, to send a wireless control signal 193 of a corresponding light intensity. The wireless control signal 193 may include a Bluetooth signal, an infrared signal, a Zigbee signal, a Wifi signal, and wireless control signals of various frequencies.

[0039] The regulating card 153 includes a signal transceiver 1530. The signal transceiver 1530 includes an antenna 1531 and a modulating and demodulating unit 1532. The antenna 1531 is configured to receive the wireless control signal 193, and transmit the wireless control signal 193 to the modulating and demodulating unit 1532. The modulating and demodulating unit 1532 generates a first regulating signal 194 after demodulating the wireless control signal 193. The modulating and demodulating unit 1532 may be implemented in the form of hardware, software, or a combination of hardware and software.

[0040] In some implementations, the regulating card 153 further includes a controller 1533. The controller 1533 may include any suitable programmable circuit or apparatus, including a Digital Signal Processor (Digital Signal Processor, DSP), a Field Programmable Gate Array (Field Programmable Gate Array, FPGA), a Programmable Logic Controller (Programmable Logic Controller, PLC), an Application Specific Integrated Circuit (Application Specific Integrated Circuit, ASIC), and the like. The controller 1533 may be implemented in the form of hardware, software, or a combination of hardware and software. In some implementations, the modulating and demodulating unit 1532 may be a processing unit in the controller 1533 or be a part of a circuit integrated into the controller 1533.

[0041] The controller 1533 is configured to receive the first regulating signal 194, to generate a second regulating signal 195 required for regulating the dimming module 125, and transmit the second regulating signal 195 to the second signal terminal 157. In this case, the second regulating signal 195 is used as the regulating signal of the driving circuit 121, to regulate the light intensity of the lighting assembly 111. As shown in FIG. 2, when the regulating card 153 is inserted into the port 150, the second regulating signal 195 is transmitted to the dimming module 125 via the first signal terminal 1501, to regulate the second power, and more specifically, to regulate a voltage, a current, and/or a power of the second power, thereby implementing the light intensity tuning function of the LED array 120.

[0042] For example, when the wireless control signal 193 indicates changing from a 50% light intensity to a 80% light intensity, the controller 1533 may generate the corresponding second regulating signal 195 according to the wireless control signal 193. The second regulating signal 195 may be used to regulate the dimming module 125, so as to enhance the power provided to the LED array 120, thereby enhancing the light intensity of the LED array 120.

[0043] In some implementations, when the dimming module 125 includes a switching device, such as an insulated gate bipolar translator (Insulated Gate Bipolar Translator, IGBT), the second regulating signal 195 may include a pulse width modulation switching signal, and the switching signal may control the turning on and off of the corresponding switching device, to adjust a voltage and/or a current transmitted to the LED array 120, thereby regulating the light intensity of the LED array 120.

[0044] In another implementation, the controller 1533 may be integrated into the driving circuit 121 as shown in FIG. 6, and the first regulating signal 194 may be transmitted to the second signal terminal 157. In this case, the first regulating signal 194 is used as the regulating signal of the driving circuit 121, to regulate the light intensity of the lighting assembly 111. As shown in FIG. 6, when the regulating card 153 is inserted into the port 150, the first regulating signal 194 is transmitted to the controller 1533 of the driving circuit 121 via the first signal terminal 1501. The controller 1533 generates, according to the first regulating signal 194, the second regulating signal 195 required for regulating the dimming module 125, and transmits the second regulating signal 195 to the dimming module 125, so as to control the dimming module 125 to regulate the second power. More specifically, a voltage, a current, and/or a power of the second power is regulated, thereby implementing the light intensity tuning function of the LED array 120. The reason why the controller 1533 is integrated into the regulating card 153 rather than the driving circuit 121 in the implementation of FIG. 3 is that, such a design may further lower the cost of separately purchasing the lighting assembly 111.

[0045] As compared with the regulating card 153 shown in FIG. 3, the regulating card 153 shown in FIG. 4 further includes a sensor 1535. The sensor 1535 may be configured to detect a state signal of the lighting assembly 111. For example, a temperature sensor is adopted to detect a temperature signal. The sensor 1535 may further include a sensor of another type, such as a humidity sensor used to detect an air humidity signal. The regulating card 153 may transmit a corresponding alarm signal to the external remote-controller 191 according to a detection signal obtained by the sensor 1535, to inform a user that the lighting assembly 111 may have failed, for example, a temperature is too high. After obtaining a failure message, the user may further control the external remote-controller 191 to send a corresponding external control signal, to enable the regulating card 153 to provide a regulating signal, so as to regulate the light intensity of the lighting assembly 1 11. For example, the light intensity is decreased to lower the temperature inside the lighting assembly 111 , so as to ensure normal operation of the lighting assembly 111. In another implementation, the external remote-controller 191 may be provided with an automatic regulating program. That is, a corresponding regulating signal is automatically sent after a failure occurs, so as to regulate the light intensity of the lighting assembly 111.

[0046] The regulating process of an implementation includes a monitoring process and a dimming process. The monitoring process is as follows: in some implementations, the controller 1533 controls the sensor 1535 to convert a detection signal into a sensor output signal 293 and transmit the sensor output signal 293 to the controller 1533. In another implementation, the sensor 1535 may be installed on the lighting assembly 111. In this case, the sensor output signal 293 of the sensor 1535 may be transmitted to the controller 1533 via a terminal of the port 150 and a terminal of the regulating card 153. The controller 1533 performs calculation processing on the sensor output signal 293. In some implementations, when the sensor output signal 293 exceeds a preset value, the controller 1533 outputs an alarm signal 294. In this case, the signal transceiver 1530 may receive the alarm signal 294, convert the alarm signal 294 into a modulating signal 295 corresponding to the alarm signal 294, and transmit the modulating signal 295 to the external remote-controller 191. More specifically, the modulating and demodulating unit 1532 receives the alarm signal 294, modulates the alarm signal 294, and then generates the modulating signal 295. The modulating signal 295 is transmitted by using the antenna 1531 and is received by the remote control apparatus 191.

[0047] According to the modulating signal 295, the user may control the remote control apparatus 191 to send the external control signal, so that the regulating card 153 provides the regulating signal, so as to regulate the light intensity of the lighting assembly 111.

[0048] The dimming process has been described in detail with regard to FIG. 3. Therefore, details are not described herein again.

[0049] Taking a temperature sensor 1535 as an example, when a temperature detection signal of the lighting assembly 111 indicates that a temperature is too high, the external remote- controller 191 may be sent an alarm signal indicating that the temperature is too high after receiving the modulating signal 295. In order to lower the temperature of the lighting assembly 111, the user sends, via the external remote-controller 191, the wireless control signal 193 for lowering the light intensity. For example, a wireless control signal 193 may be sent to change the light intensity from 80% to 20%, and the dimming module 125 may be regulated according to the second regulating signal 195 to lower the power provided for the LED array 120, so as to lower the light intensity of the LED array 120, thereby lowering the temperature of the lighting assembly 111.

[0050] As compared with the regulating card shown in FIG. 4, the signal transceiver 1530 is removed from the regulating card 153 shown in FIG. 5. In this implementation, the controller 1533 controls the sensor 1535 to convert a detection signal into a first regulating signal 296 and transmit the first regulating signal 296 to the controller 1533. In this case, the detection signal is used as the control signal. For example, an audio detection signal detected by a sound control sensor or a temperature detection signal detected by a temperature sensor may be used as the control signal, and the sensor 1535 converts the control signal into the first regulating signal 296. After performing calculation processing on the first regulating signal 296, the controller 1533 outputs a second regulating signal 195, where the second regulating signal 195 is output to the first signal terminal 1501 via the second signal terminal 157 and is further transmitted to the dimming module 125, so as to control the dimming module 125 to regulate the second power, and more specifically, adjust a voltage, a current, and/or a power of the second power, thereby implementing the light intensity tuning function of the LED array 120.

[0051] For example, when a temperature signal of the lighting assembly 111 indicates that a temperature is too high, it is necessary to lower the light intensity. The sensor 1535 may receive the temperature signal, and convert the temperature signal into the first regulating signal 296. The controller 1533 generates the second regulating signal 195 according to the first regulating signal 296. The dimming module 125 may be regulated according to the second regulating signal 195, so as to lower the power provided for the illumination module 120, thereby lowering the light intensity of the LED array 120.

[0052] As shown in FIGs. 3-5, the regulating card 153 is encapsulated in a form of an SD card, and includes three terminals. The terminal of the port 150 shown in FIG. 2 is arranged to match the terminal of the regulating card 153. When the regulating card 153 is inserted into the port 150, the voltage converter 127 outputs a port voltage via output terminals 128 and 129, and supplies power for the controller 1533 of the regulating card 153 via power supply terminals 155 and 159. The second signal terminal 157 is configured to output a regulating signal to the dimming module 125. In another implementation, corresponding encapsulation terminals may be added according to the number of required signals.

[0053] FIG. 7 is a schematic circuit diagram of a lighting device 100 according to another implementation of the present invention. In this implementation, the lighting device 100 has a color of light and light intensity tuning function. Compared with the lighting device 100 shown in FIG. 2, the lighting device 100 similarly includes a lighting assembly 111 and a regulating card 153. As an example, the lighting assembly 111 includes a lamp holder 117, an illumination module 120, and a driving circuit 121. In some implementations, the lighting assembly 111 further includes other elements that are not shown.

[0054] However, in this implementation, the illumination module 120 includes two groups of illumination units, namely, LED arrays 1201 and 1203. The two groups of LED arrays 1201 and 1203 may emit light of two different colors, such as yellow light and white light. The two groups of LED arrays 1201 and 1203 are arranged in a uniform and intersecting manner, so that the light of two different colors may be mixed uniformly to form light of another color. Correspondingly, the dimming module 125 in the driving circuit 121 includes two dimmers 1251 and 1253, which are respectively connected to the two groups of LED arrays 1201 and 1203.

[0055] When the lighting assembly 111 is used for common illumination, that is, when it is unnecessary to implement the light intensity and color of light tuning function, after the converter 123 converts the first power into the second power, the second power is provided to the two groups of LED arrays 1201 and 1203 respectively via the two dimmers 1251 and 1253. According to different demands for colors of light, the illumination module 120 may include multiple groups of illumination units, the driving circuit 121 includes a plurality of

corresponding dimmers, and each dimmer is connected between a lamp holder 117 and a corresponding illumination unit, for receiving the regulating signal and respectively regulating, according to the regulating signal, the power output to corresponding illumination unit.

[0056] In some embodiments of the present invention, the port 150 is arranged on a housing of the lighting assembly 111 to accommodate the regulating card 153. When it is required to use the lighting assembly 111 to implement the light intensity and color of light tuning function, the regulating card 153 may be inserted into the port 150. Like the lighting device 100 shown in FIG. 2, when the regulating card 153 is inserted into the port 150, the regulating card 153 is configured to receive an external control signal, to output regulating signal to the driving circuit 121. More specifically, the regulating signals, such as 1951 and 1953, are respectively used to control corresponding dimmers 1251 and 1253, to adjust the second power, and more specifically, adjust a voltage, a current, and/or a power of the second power, thereby regulating the light intensities of the corresponding LED arrays 1201 and 1203. According to different colors and different light intensities of the two groups of LED arrays 1201 and 1203, the illumination module 120 may implement the light intensity and color of light tuning function, and the specific operating principle is not described herein again.

[0057] Similarly, the regulating card 153 shown in FIG. 7 may adopt the circuit structure and encapsulation form shown in FIGs. 3-5. However, in this implementation, the dimming module 125 needs at least two regulating signals, such as the regulating signals 1951 and 1953, to respectively control the two corresponding dimmers 1251 and 1253. Therefore, corresponding second signal terminals may be added to the regulating card 153 according to the number of required regulating signals, and first signal terminals are also added to the port 150,

correspondingly. [0058] Although the present invention is described with reference to specific implementations, a person skilled in the art should understand that, many modifications and variations may be made for the present invention. Therefore, it is to be understood that the intention of the claims lies in all the modifications and variations covered in a real concept and scope of the present invention.
