Abstract

A system and method for discovering at least one dimming control protocol installed in a plurality of lighting devices and for controlling a plurality of dimming levels of the plurality of lighting devices are disclosed. The system may include at least one gateway that connects to at least one plurality of luminaires and/or LED'"'"'s, at least one sensor subsystem and at least one power meter. The system and method may exchange information between a plurality of light devices and a self-organized, self-discovering gateway device. The gateway may use one or more known control protocols as an input and is able to handle multiple light devices that support different control protocols. This ability makes the gateway a universal lighting control gateway.

Claims

at least one protocol agnostic Universal Smart Lighting Gateway, the Universal Smart Lighting Gateway configured for discovering the at least one dimming control protocol installed in each of the plurality of lighting devices and controlling the dimming levels of each of the plurality of lighting devices;

a plurality of luminaires, wherein the plurality of luminaires is physically connected to the at least one protocol agnostic Universal Smart Lighting Gateway via at least one dimming control interface;

at least one sensor subsystem, wherein the sensor subsystem senses a plurality of color channel and monitors at least one change in light and environment in real time, and wherein the sensor subsystem is connected with the at least one of the protocol agnostic Universal Smart Lighting Gateway; and

at least one power meter for measuring power in real time, wherein the at least one power meter is connected with the at least one of the protocol agnostic Universal Smart Lighting Gateway.

2. The system of claim 1, wherein the at least one protocol agnostic Universal Smart Lighting Gateway discovers the at least one dimming control protocol, the dimming control protocol comprising one of 0V-10V, 1V-10V, DALI, and DMX.

3. The system of claim 1, wherein the plurality of luminaires comprise a plurality of LED'"'"'s, and the plurality of luminaires are configured to receive at least one dimming control command from the at least one protocol agnostic Universal Smart Lighting Gateway during a protocol discovery process, the dimming control command being transmitted via the at least one dimming control interface.

4. The system of claim 1, wherein the at least one sensor subsystem comprises at least one of a color sensor and at least one environment sensor.

5. The system of claim 4, wherein the at least one color sensor faces the plurality of luminaires, and senses at least one of a color content and a color intensity of at least one of the plurality of luminaires and the plurality of LED'"'"'s.

6. The system of claim 4, wherein the at least one environment sensor senses a nearby environment of the plurality of luminaires while facing away from the plurality of luminaires.

7. The system of claim 4, wherein the at least one environment sensor comprises at least one of an ambient light sensor, and a temperature sensor.

8. The system of claim 1, wherein the at least one protocol agnostic Universal Smart Lighting Gateway is connected to at least one network gateway in a backhaul via at least one of a LAN, a WLAN, a WAN, and a Mesh BLE radio network.

9. The system of claim 8, wherein the at least one network gateway is connected to at least one cloud server in the backhaul via one of a WAN and a LAN.

10. The system of claim 1, wherein the Universal Smart Lighting Gateway discovers the at least one dimming control protocol by:
