Detailed Description of the Invention

Figs. 1-3 provide several views of a smart light switch according to one embodiment of the present invention. Smart light switch 1 includes several elements, specifically knob 10 having a knob screen 11, a plurality of function buttons 20, and a frame 30.

Knob 10 may be configured to rotate and/or to be pushed in. Knob 10 may be configured to rotate while being pushed in. Knob 10 may be configured to adjust certain environment settings, such as lighting brightness, audio volume, thermostat temperature, and the like. Preferably, knob screen 11 does not rotate upon rotation of knob 10. Knob screen 11 may be composed of any commonly-known display screen technology, including LCD, LED, OLED, QLED, plasma, e-ink, and the like. In a preferred embodiment, the display of knob screen 11 is an e-ink display. The plurality of function buttons 20 may be set around knob 10. The smart light switch of the present invention may include any plurality of function buttons. In a preferred embodiment, the smart light switch includes four function buttons in a quadrant-based arrangement. Each function button 20 is capable of being pressed individually. Accordingly, each function button 20 may be configured to represent a preset function relating to lighting, audio, and/or temperature. Present functions may include lighting scenes, music playlists, and automation in certain Thread network protocol products.

The smart light switch of the present invention may be configured to control traditional wired lights. Moreover, the smart light switch may be configured to control third party smart environment products that accept connections via BLUETOOTH Low Energy (BLE) , WI-FI, ZIGBEE, and/or Thread protocols, including but not limited to PHILIPS HUE, LIFX, SONOS, NEST, SMARTTHINGS, and WINK. In a preferable embodiment, the smart light switch of the present invention is capable of making outgoing connections only, except in the instance of accepting connections from an application specifically designed for the smart light switch of the present invention. BLE may be used with respect to such connections. The application may be available on IOS- and/or ANDROID-capable mobile devices. Firmware updates may be performed by the smart light switch, such as on a regular schedule, as opposed to receiving updates pushed from a cloud source .

The smart light switch may be approximately the size of a U.S. double-gang light switch. Moreover, the electronic components of the smart light switch may be compact enough to fit over or within a U.S. single-gang box. Therefore, the smart light switch of the present invention may be utilized in replacing both single switches and double switches .

The smart light switch may include one or more sensors. The sensor (s) may detect light, temperature/humidity, and/or motion. A light sensor may be directed to efficiency purposes, such as dimming lights when a covered area is already receiving sufficient natural light. A motion sensor may react to the approach or the departure of an individual in the covered area. Upon approach of the individual, the smart light switch may turn on or otherwise become active. Upon the departure of the individual, the smart light switch may turn off, go into sleep mode, or otherwise become inactive .

The smart light switch may include an internal speaker. The internal speaker may be capable of communicating feedback regarding an individual' s interactions with the smart light switch. The smart light switch may also include a microphone. The smart light switch may be capable of setting a timer and/or a schedule for lighting controlled by the smart light switch.

Additionally, another aspect of a smart light switch according to one embodiment of the present invention is a light color control aspect. A smart light switch may include a circuit board, such as a printed circuit board assembly (PCBA) , which may be disposed in a plastic or metal housing, where the circuit board is configured to control light color of an associated multi-color light source by adjusting the allocation or proportion of each color in the multi-color light source. The multi-color light source may be, but is not limited to, a red-blue-green (RGB) light-emitting diode (LED) . Light color control may involve discrete color changes or continuous color changes.

The smart light switch of this embodiment may also have radio frequency (RF) communication capabilities including but not limited to BLUETOOTH Low Energy (BLE) , WI-FI, ZIGBEE, and the like, such that the smart light switch communicates and controls the associated light (s) via RF means. The color may be controlled and/or adjusted by a knob or button disposed on the body of the smart light switch or by a mobile device application associated with the smart light switch. For example, the mobile device may be able to communicate with the smart light switch through the wireless communication capability.

Additionally, another aspect of a smart light switch according to one embodiment of the present invention includes a self-powering feature. A switch of this embodiment may also have a dimmer feature. The dimmer feature may be one or more of a preset light intensity adjustment, a complete power off, a complete power off upon light levels falling below a preset level, and the like. The switch may have an energy-harvesting mechanism for self-powering an RF transmitter. The energy-harvesting mechanism may include but is not limited to a piezoelectric element, an electromagnetic system, and the like. A mechanical action may need to be performed in order to capture energy, with such action including but not limited to pushing a button, moving a slide, and the like. Accordingly, a mechanical actuation mechanism may be a button actuator, a slide actuator, or a dual polarity actuator. In this embodiment, the switch does not need to access any wiring harness in order to function.

The switch of this embodiment may include an RF transmitter assembly having a mechanical actuation mechanism, an energy-harvesting mechanism, and circuitry configured to convert harvested energy into an RF signal. The switch may also include a light dimming circuitry and a wireless receiver configured to send control signals to the light dimming circuitry after receiving the signal from the RF transmitter. The RF signal may be one signal or multiple signals. The wireless receiver may send control signals corresponding to each received RF signal.
