Abstract

A light fixture is provided or retrofitted with wireless LED lighting system requiring no additional wireless devices. An LED driver housing has power output terminals and control input terminals for an LED driver disposed therein. An LED lighting device includes driver input terminals to receive the output power from the LED driver, and to which an LED array and a wireless communication module are coupled to receive power therefrom. The wireless communication module comprises a transceiver configured to send and receive wireless communication signals with respect to an external device, and a controller linked to the transceiver and configured to generate lighting output control signals. Dimming control signals received via the transceiver may be processed by the controller and transmitted to the driver without requiring additional hardware or wiring within or attached to the driver. The lighting device also can wirelessly receive occupancy sensor data or LED configuration information.

First claim

What is claimed is:

1. An LED lighting device comprising:
first and second input terminals configured to receive input power from an LED driver when coupled thereto;
one or more light emitting diodes (LEDs) coupled in series across the first and second input terminals and configured to generate a lighting output corresponding to the input power;
a wireless communication module coupled to the first and second input terminals to receive input power therefrom, the wireless communication module comprising
a transceiver configured to send and receive wireless communication signals with respect to an external device, and
a controller linked to the transceiver and configured to generate lighting output control signals; and

first and second output terminals configured to transmit the lighting output control signals to the LED driver when coupled thereto.

2. The LED lighting device of claim 1 , wherein the transceiver is configured to receive dimming control signals from the external device, and wherein the controller is configured to generate lighting output control signals corresponding to a desired lighting output from the dimming control signals.

3. The LED lighting device of claim 2 , wherein the controller is further configured to receive wireless input signals via the transceiver from one or more environmental sensors and determine an environmental condition associated with the lighting device, and
wherein the transceiver is configured to transmit to the remote device environmental data corresponding to the environmental condition.

4. The LED lighting device of claim 3 , wherein one or more of the environmental sensors are occupancy sensors from a group comprising passive infrared detectors and sound detectors, and the controller is configured to determine an occupancy state with respect to the lighting device based at least in part on the input signals from the occupancy sensors.

5. The LED lighting device of claim 2 , wherein the controller is configured to receive and store LED configuration information associated with an input power required to generate the desired lighting output, and wherein the wireless communication module is configured to transmit signals corresponding to a stored LED module configuration to an LED driver controller when coupled thereto and to the external device.

6. The LED lighting device of claim 5 , wherein the LED configuration information comprises one or more parameters from a group comprising a number of LEDs coupled in series and a number of LEDs coupled in parallel with respect to the first and second input terminals.

7. The LED lighting device of claim 5 , wherein the controller is configured to receive input signals from one or more lighting output sensors and store corresponding lighting output information over time, and
wherein the transceiver is configured to transmit to the remote device a lighting depreciation status corresponding to changes over time in lighting output relative to the input power.

8. The LED lighting device of claim 1 , further comprising an antenna coupled to the transceiver of the wireless communication module.

9. The LED lighting device of claim 1 , further comprising an antenna integral with respect to the wireless communication module.
