Prior Art

From the background art, non-patented literature, the company Nanoleaf is known to produce light bulbs with LED diodes. Their light bulbs resemble the form of classic bulbs with a light-bulb power connector. Instead of a well-known, pear-like glass body of a bulb, the Nanoleaf bulbs are a geometric body of nine regular pentagons whose surface holds three LED diodes each. Unlike the solution according to the invention, these bulbs from the background art in their shape remind of old classical bulbs, and their function is the same as the function of the old bulbs.

The same company also has a product called smart light. The smart light of the

Nanoleaf Company includes a lamp in the form of triangles with LED diodes, which are arranged in one plane. A combination of lighting triangles on the wall makes a decorative light and some sort of artistic creation. These lamps differ in their design from the solution according to the invention. In addition, they are two-dimensional and have to be attached to the wall.

From non-patented literature, there is also an example of a modular lighting by designer Bruno Fosi. Its modular lighting includes elements of the shape of a parallelepiped which can have LED diodes on one of its bases. By combining connections in various ways of basic elements in the form of a parallelepiped an interesting lighting appears in the room. The only common features of Bruno Fosi's creations and the solution according to the invention is modularity and the use of LED diodes.

All of the above stated solutions from the background art apply only to the lamp. None of the solutions has the ability to be used in the same design as a loudspeaker or as a camera. Only the Olixar Company has a solution for the device, which is both a light and a loudspeaker. With this solution, the light and loudspeaker are the accompanying elements of a bluetooth, unlike the solution according to the invention, which can perform as an independent lamp or as an independent speaker.

Disclosure of Invention

The modular electrical system, according to the invention, includes a number of interconnected base devices. The base device is in the shape of an equilateral triangle. However, it is possible that the base device also takes the shape of a square, a regular pentagon or any other regular polygon. The system, according to the invention, includes a single device for power supply which suplies the system with electricity, and one or more operating devices. The number of operating devices in the modular system accoding to the design is not limited, but it is limited by the power of the transformer which is a part of a power supply device, as well as electrical conductivity of the electrical contacts. According to the invention, the modular electrical system may, apart from a power device and operating devices, also include a battery device. Two new independent modular electrical systems may be formed out of the modular electrical system consisting of a power supply device, a number of operating devices and a battery device, where one system would include a power supply device and operating devices, and the other system would include a battery device for a power supply and operating devices which the battery supplies with power.

The devices are inter-connected with magnets located at the outter edges of the devices. Depending on the number of connected devices, a modular electrical system may have, for example, a form of tetrahedron, octahedron, dodecahedron, and icosahedron or any other regular, irregular, closed or open geometrical body with regular polygons as its sides. The devices of the modular electrical system, according to the invention, may be in a shape of any regular polygon.

The modular electrical system may operate as a lamp when LED diodes are placed in operating devices. System may also have a wireless speaker in operating devices, so it may operate as a loudspeaker, or have a wireless camera and operate as a recording camera. Operating devices are not mutually exclusive, so various operating devices may be located in a system so the modular electrical system may operate as a lamp with a loudspeaker and a camera. In addition, the battery device with a temporary power supply function, can also be added to the modular electrical system, according to the invention.

According to the invention, the modular electrical system uses a harmless direct low- voltage current. The power source may vary. 220V alternating current from the grid can be used and connected to the power supply device via a power cable. In this version, the system in its power supply device includes a transformer, which transforms 220V alternating current into a low-voltage direct current. The required direct low-voltage current may be connected directly to the power supply device. Power supply device may include, as a source of power, a solar cell or it may harness wireless power.

Electricity transfer between base devices is carried out through a set of five electrical contacts at each edge of the device.

Interconnection of base devices within a modular electrical system is achieved by a set of two modular magnets at each edge of the device.

Detailed description of the invention

The modular electrical system 505, according to the invention, consists of devices 100, 200, 300 in the shape of an equilateral triangle, which are easily and simply connected, thus creating various forms of a modular electrical system.

The modular electrical system 505 includes one power supply device 100 and one or more operating devices 200. The modular electric system 505, according to the invention, apart from the power supply device 100 and the operating device 200 may also include the battery device 300. When modular electrical system 505, apart from the device 100, 200, includes the battery device 300, then the battery 300 is being charged. The charged battery 300 can temporarily replace the power supply device 100, and then the modular electrical system 505 consists of the battery device 300 and one or more operating devices. Devices 100, 200 and 300 connect with each other at an edge of the equilateral triangle shape, where modular magnets 35 bind them together. The transmission of the electrical current from the power supply device 100 to the operating devices 200 and the battery devices 300, as well as the transmission of the electrical current between operating devices, is accomplished through a set 5 of electrical contacts 10, 15, 20. The electrical contact 10 is the ground for all devices, whilst the contact 15 is used to power all operating devices except the operating device 205. The contact 20 is only used for powering operating devices 205, so they always have independent power source from all other devices. The battery device 300 can also be powered via contacts 15 or 20.

The design of the power supply device 100 is defined by the energy form the power supply device is connected to. The power supply device 100 may have multiple designs, including: power supply device 105 when alternating current is supplied; power supply device 145 when direct current is supplied; power supply device 155 when solar energy is used; power supply device 165 when power is harnessed wirelessly.

The power supply device 105, supplied with 220V alternating current (AC) includes upper casing 115 and lower casing 125. Circular part 120 has been designed in the upper casing 115, which morphs mto outlet 119 for fixing the light-bulb power connector 107. The outlet 119 is made of a material which does not conduct electricity. Upper casing contains a transformer 108 for transfonning the AC 220V into a harmless direct low- voltage current required for the functioning of the modular electrical system. Voltage used for the operation of the devices can be 3, 6, 9, 12 or 24V. 12V is most commonly used. The transformer is fixed to a triangular circuit printed board which is the controller 109. In addition to the controller 109, wireless modem 65 is also placed on the printed circuit board. The controller 109 channels the transformed electrical current from the transformer 108 to the distributor 25. On the underside, opposite of the light-bulb power connector 107, the power supply device 105 includes bottom cover 135, which sits on the lower casing 125 fixed by the controller 109. The upper casing 115 of the power supply device 105 from the inner bottom side in all three corners of the device 105 has an angular reinforcement 117 with a thread. The fixing screw 45 is screwed into the thread through the lower casing 125. The function of the fixing screw 45, apart from connecting the upper and the lower casing of the power supply device 105, is also to secure the position of the lower cover 135, the printed circuit board with the controller 109 and the direct current distributor 25. The upper surface of the upper casing ends with a small outlet 118. The outlet 118 of the upper casing 115 is attached to a tooth 131 of the lower casing 125. In this way, an even edge is formed along an external visible joint of the upper 115 and the lower 125 casings. The upper casing 115 includes an outlet 116, which is adjacent to the lower casing with a small gap in contact with the electrical contacts 10, 15 and 20 and holds them in a fixed position. In addition, it allows for a controlled connection of the main elements of the device 105, set 5 of the electrical contacts 10, 15 and 20 and the distributor 25.

The wireless modem 65 is used for wireless control of the controller 109, via a wireless controller 60 that may be a smartphone or similar. Using wireless control, power supply to the electrical contact 15 or to the electrical contact 20 can be switched off, independently of each other, making the wireless controller 60 the main controller of the entire system, and thus allowing the system to be controlled remotely from a distance.

The lower casing 125 of the device 100, 200, 300 is in the shape of a triangular section.

A thread is made in part 128 of the lower casing 125, which is parallel to the reinforcement 117 of the upper casing 115, into which the fixing screw 45 is fitted to fix the lower casing 125 to the upper casing 105. In each side of the lower casing 125 two recesses 126 are made, into which a set 30 of two modular magnets 35 of a cylindrical shape is placed. The recesses 126, as well as the modular magnets 35, are symmetrical to the axis of that side of the lower casing 125 and they are positioned in the same way on all sides of the device 100, 200 and 300. The recesses 126 fix the position of the magnets 35 in the lower casing 125 of the device 100, 200 and 300 and at the same time separates the electrical contacts 10 and 15. The magnets 35 in the set 30 of modular magnets are thus diametrically magnetized, with the north pole 40 and the south pole 41 asymmetrically positioned on each side in relation to the longitudinal axis of that side of the device. The outer edge of the lower casing 125 has a rounded end 130 that follows the shape of the magnet 35. The rounded end 130 of the lower casing 125 allows for equal and uniform connection at different angles of the lower casings 125 of the devices 100, 200 and 300 in relation to the vertical cross-section through the device. The rounded end 130 of the lower casing 125 ends with a tooth 131 which is attached to the outlet 118 of the upper casing 115. In this way, an even edge is formed along the outer visible connection of the upper 115 and the lower 125 casings.

In addition to the set 30 of modular magnets, on each side of the lower casing 125, a set 5 of modular electrical contacts 10, 15 and 20 is also placed in the same way. In each set 5 of modular contacts there are five contacts, one modular contact 10 and two each of modular contacts 15 and 20. The contacts 15 and 20 are positioned symmetrically with respect to the axis of the side of lower casing 125. The modular electrical contact 10 is inbetween the magnets 35 in the recesses 126. The modular electrical contacts 15 and 20, which are on the outter side of the magnets 35, are mutually separated from by a protrusion 127 of the lower casing 125.

The modular electrical contacts 10, 15, and 20 are of such a shape that one side is rounded, sits proud from and follows the shape of the rounded part of the lower casing 130. Further to this, their geometry is reminescent of a square with rounded angles, where at the fourth angle the side 51 of the contacts 10, 15 and 20 is twice folded to form the straight part 55 for their fixing in place. Each rounded angle in the geometry of the contacts 10, 15 and 20 is flexible and the modular electrical contact operates as a spring when pressed. When two devices 100, 200, 300 are connected, modular magnets 30 provide a precise connection with respect to the axis of the side of the devices they touch along at any angle from 0° to 180° in relation to the vertical cross-section through the devices. Furthermore, this enables a precise connnection of the respective modular electrical contacts 10, 15 and 20 between the two devices 100, 200 and 300, while the protrusion of the modular contacts 10, 15 and 20 in relation to the rounded part of the lower casing 130 and their mnctioning as a spring by mutual pressure, provides a continuous flow of electrical current between modular electrical contacts 10, 15 and 20 from one device to another.

The contacts 10, 15, and 20 sit with one part on the lower casing 125, and the folded end 55 of the modular electrical contacts 10, 15 and 20 is firmly positioned between the outlet 116 of the upper casing 115 and the distributor 25. The end 55 of the contacts 10, 15 and 20 is attached to the distributor 25.

Distributor 25 is in a triangular shape, as it follows the shape of the device 100, 200, 300. In the case that the device 100, 200, 300 is in the shape of a square, a regular pentagon or other regular polygon, the distributor 25 would be of the same shape. All contacts 10, 15 and 20 of all three sets 5 of the modular electrical contacts 10, 15 and 20 are connected by soldering to the distributor 25. All electrical contacts 10, 15, and 20 at one side of the device 100, 200 and 300 are connected through the distributor 25 with the corresponding electrical contacts 10, 15 and 20 on the other sides of the device 100, 200 and 300. In this way, the direct current from the controller 109 is transmitted via the distributor 25 to the contacts 10, 15 and 20 in the sides of the device 100, and by direct contact with the corresponding electrical contacts 10, 15 and 20 of the device 200 and 300 further through the distributor 25 to the other contacts 10, 15 and 20 at the other sides of this device and further through the entire system. In the lower casing 125, a tooth 129 encroaches into the electric contacts 10, 15 and 20 and thus secures the position of the electrical contacts 10, 15, 20 in the lower casing 125. In addition, the tooth 129 provides stability to the lower casing 125.

Figure 6 shows the block diagram of the electric current path and magnets in the power supply device 105 which is supplied by alternating current. From an external AC 220V source, the electric current is transmitted via the main power connector 107 to the transformer 108. The transformed direct current of 12V is distributed from the transformer 108 via the controller 109 and the distributor 25 to the electrical contacts 10, 15 and 20. The wireless controller 60, which is outside the power supply device 105, controls the controller 109 via a wireless modem 65.

The power supply device 145 supplied with system required 12V direct current is of a simpler design than the power supply device 105. The power supply device 145 supplied with a direct current comprises of the upper casing 160 and the lower casing 125. The upper casing 160 and the lower casing 125, as well as the entire power supply 145, are in the shape of a triangular section.

The electricity is supplied to the power supply device 145 via a suitable cable 147 to the main connector 148 and the controller 149. The controller 149, as in the power supply unit 105, is a triangular printed circuit board which sits on the bottom cover 135 and is fixed to a part of the upper casing 117 with fixing screws 45. The controller 149 is in contact with the distributor 25, to which it further transmits the electricity. Printed circuit board also contains the wireless modem 65 with the controller 149.

The wireless modem 65 serves for the wireless control of the controller 149, using the wireless controller 60 that may be a smartphone.

The power supply device 155 uses solar energy. The power supply device 155 is of the same shape, a triangular section, as well as power supply device 145. Power supply device 155 includes a solar cell 157 of a triangular shape, set up in the upper casing 160. The current generated in the solar cell is transferred to the controller 159 and further to the distributor 25. The power supply device 155 is envisaged to operate in combination with the battery device 300, to charge it. Power supply device 155 may also include an internal battery 158 placed under the solar cell 157. In this case, power supply device 155 would be a battery at the same time.

When energy is supplied to a power supply device 100 wirelessly, then power supply device 165 includes a wireless energy conversion module 167 and an internal rechargeable battery 168. The wireless conversion module 167 and the internal rechargeable battery 168 are set in the upper casing 160 below the upper cover 170 of the power supply device 165.

The modular electrical system, according to the invention, also includes the battery device 300. The design of the battery device 300 is substantially alike the design of the previously described power supply device 105, 145, 155, 165. The battery device 300 includes an upper casing 310 and a lower casing 125. The upper casing 310 and the lower casing 125, as well as the entire battery device 300, are in the form of a triangular section. The upper casing 310 is identical to the upper casing 160 of the power supply device 145, 155, 165. The battery device 300 also includes an internal rechargeable battery module 301 and a controller 303 which are set in the upper casing 310 of the battery device 300 below the upper cover 315. In the upper casing 310, battery device 300 includes a switch 302 to switch the battery off. The switch 302 is used only when the battery 300 provides electrical current to the operating device 200. When the battery 300 is charged by the power supply device 100, the switch 302 is not used. When the battery 300 is connected to the power device 100, directly connected to the power device 100 or via operating devices 200 connected to the power supply device 100, the battery device 300 is being charged. Then the current from the power supply device 100 is transmitted via electrical contacts 10, 15 and 20 to the distributor 25 of the battery 300, and from the distributor 25 to the controller 303 and further to the internal rechargeable battery 301. When battery 300 is charged up and connected to the operating device 200 without the presence of the power supply device 100 and with the switch 302 turned on, then the battery device 300 operates as a power supply device. In this case, the current from the internal rechargeable battery 301 via the controller 303 is transmitted to the distributor 25 and further to the electrical contacts 10, 15, 20 of the battery device 300. Through the electrical contacts 10, 15 and 20 of the battery 300, which are in contact with the contacts 10, 15 and 20 of the operating device 200, electrical current is transferred to the operating device.

The operating device 200 may also have multiple versions depending on the assigned use.

The versions of the operating device 200 include: operating device 205 lamp; operating device 240 wireless speaker; operating device 250 wireless camera and microphone; operating device 260 wireless display; operating device 270 sensor and operating device 280 without designated use.

The operating device 205 operating as a lamp comprises an upper casing 210 and a lower casing 125. The upper casing 210 and the lower casing 125, as well as the entire operating device 205, are in the form of a triangular section.

The upper casing 210 of the operating device 205 is of the same shape as the upper casing 160 of the power supply device 145, 155 and 165 and the upper casing 310 of the battery device 300. The flat upper surface of the upper casing 210 ends with a small outlet 213. The outlet 213 is attached to a tooth 131 of the lower casing 125. In this way, an equal edge is achieved along the outer visible connection of the upper casing 210 with the lower casing 125. From the inside, the upper casing 210 has an outlet 211 towards the lower casing 125. The outlet 211 is in contact with the distributor 25 and the set 5 of the modular electrical contacts 10, 15 and 20. The outlet 211 provides a uniform and controlled contact between the main parts of the device 205, distributor 25 and the modular electrical contacts 10, 15 and 20. In addition, the outlet 211, as well as the entire upper casing 210, operates as a heat-sink for the lighting module 206. The upper casing 210 is made of thermally conductive material - like thermal plastic, anodized aluminum or some other metal with the protection against conducting electrical current. In the inner corners, the upper casing 210 includes a reinforcement 212 with a threaded section. The fixing screw 45 is fastened in the thread to connect the upper 210 and the lower 125 casings. Controller 207 of lighting module 206 is a part of the distributor 25.

The lower casing 125 of the operating device 205 is identical to the already described casing 125 of the power supply device 100 and the battery device 300.

At the bottom, the operating device 205 is closed with a cover 230. The cover 230 in the operating device 205 also has a light reflecting function. Transparent filter 231 for a direct dispersion of light from the illuminating LED diodes 233 is placed on top of the cover 230.

The lighting module 206 is also a part of the distributor 25 of the operating device 205.The lighting module 206 includes: light-emitting diodes (LED) 233, reflectors 235, and resistors 234. The LED diode 233 is in contact with the distributor 25 through which it receives electricity. On the other side, it is fixed with the transparent filter 231 of the operating device 205. The reflectors 235 are positioned between the diodes. The light from the LED diodes 233 is reflected by the reflectors 235 and the bottom cover 230. The resistors 234 carry out voltage normalization function for the LED diodes 233.

The operating device 205 is connected to the power supply device 100 or the battery

300, either directly or through other operating devices 200, via a set 30 of modular magnets, which attract and are connected with the set 30 of magnets of the power supply device 100 and / or the battery device 300 and / or other operating devices 200. The operating device 205 receives electricity through a set 5 of modular electrical contacts, that are in contact with the set 5 of the modular electrical contacts of the power supply device 100 or the battery device 300 either directly or via other operating devices 200. The electricity is transferred from the contacts 10, 15 and 20 to the distributor 25, and from it to the controller 207, and further to the lighting module 206.

The operating device 240 operating as a loudspeaker comprises an upper casing 210 and a lower casing 243. The upper casing 210 is of a triangular shape. On the upper side it is closed with a top cover 244. The top cover 244 includes holes for letting through the sound from a loudspeaker module 241. Spacer 245 is set between the upper cover 244 and a controller 242. The controller 242 sits on the flat surface of the lower casing 243. The outer shape of the controller 242 is a triangle, but in the middle of the triangle is an opening for the loudspeaker module 241 and the wireless modem 65. The lower casing 243 is thicker than the lower casing 125 previously described, as it is trapezially expanded to contain the loudspeaker module 241. In the case of the operating unit 240 loudspeaker, the device can be positioned in the system at the angles given in the figures 34a, b, c and d, and all angles inbetween but not under the angle shown in figure 34e due to the expanded casing. The reinforcements 246 for holding the controller 242 are installed in the corners of the lower body 243 of the operating unit 240. The wireless modem 65 serves to control the controller 242, using a wireless controller 60, that may be a smartphone. Wireless control can play audio material from the wireless controller 60 on the loudspeaker module 241.

The operating device 250 operating as a video and audio recorder includes the upper casing 210 and the lower casing 125, a wireless camera 251, and a microphone 252. The upper casing 210 is closed on the upper side by a top cover 257. The top cover 257 has openings 253 for a microphone 252, a wireless camera 251, a motion and light sensor 254, and an infrared light for recording at night 255. The lower casing 125 is closed on the underside by a bottom cover 258. Controller 256 sits on the bottom cover 258. The controller 256 is in the form of a triangle with holes for camera lens 251 and the wireless modem 65. The wireless modem 65 serves to control the controller 256, using a wireless controller 60, that may be a smartphone. The wireless controller 60 can display and play a video recording from the camera 251 and audio recording from the microphone 252. The motion sensor 255 would, if programmed via the wireless controller 60, react to motion during a day or a night, paired with the infrared light 254, and automatically switch on the camera and the microphone and notify the wireless controller 60 and if requested, play those video and audio recordings.

The operating device 260 as the cover of the upper casing 210 has a wireless screen 261. Controller 262 is set in the middle of the height of the operating device 260. The controller 262 is of a triangular shape with opening for setting the wireless modem 65. Between the screen 261 and the controller 262, as well as between the bottom cover 258 and the controller 262, there are spacers 245, which maintain the distance between the screen 261 and the controller 262, as well as the distance between the controller 262 and the bottom cover 258. The wireless modem 65 serves to control the controller 262, using a wireless controller 60, that may be a smartphone. A video can be displayed wirelessly from the wireless controller on the screen 261.

The operating device 270 operating as a sensor includes the upper casing 210 and the lower casing 125, a top cover 277 and a bottom cover 258. Sensors 271 and 272 are installed on the top cover 277, as well as the infrared light 273 for operation in the dark. Sensors 271 and 272 may be used for different purposes, from smoke / fire sensors to motion sensor, in which case the operating device 270 would function as an alarm device. The upper cover 277 also includes alarm loudspeaker 274 and alarm light 275. On the bottom cover 258, there is a controller 276 of triangular shape with openings for the loudspeaker 274 and the wireless modem 65. The wireless modem 65 serves to control the controller 276, using a wireless controller 60 that may be a smartphone. Using wireless control, the controller 276 would, via the wireless modem 65, in the event of an alarm, when the sensors respond to a particular alarming activity, send the signal to the wireless controller 60 about that alarming activity. In the case of smoke and fire sensors, it would warn of a potential fire hazard, and in the case of a motion sensor, of a potential danger from burglars.

The operating device 280 is of a base design, without designated use. The operating device 280 from the inside of the triangular section includes an inner cover 281, of a triangular shape, set between upper 210 and lower 125 casings. The function of the operating device 280 is the transmission of electrical current within the modular electrical system 505 without the consumption of that energy.

The described execution of the operating device 200 does not exhaust the possible new uses of the operating device 200.

The modular electrical system 505, according to the invention, may have an unlimited number of versions. All versions include one power supply device 100 in any execution, or a battery device 300 and an unlimited number of operating devices 200 with any operating use or no operating use.

One of the versions of the modular electrical system according to the invention is a combination of one power supply device 100 with a different number of operating device 200. The modular electrical system 505 may have a tetrahedron form when it consists of the power supply device 100 and two or three operating devices 200. With four operating devices 200 the modular electrical system may be in one plane. The system may have six devices, one power supply device 100 and five operating devices 200. The modular electrical system 505 may have an octahedron shape with one power supply device 100 and seven operating devices 200. It can also have ten or twenty devices.

The modular electrical system 505 may comprise one power supply device 100, a number of operating devices 200, and the battery device 300. In this version, the power supply device 100 supplies power to the operating devices 200 and charges the battery device 300. When the battery device 300 is charged with energy, the modular electrical system 505 may be divided into two modular electrical systems 505. In this situation, one system would include the power supply device 100 and a number of operating devices 200, and the other system would include the battery 300 as a power supply device and a number of operating units 200.
