LED LIGHTING DEVICE WITH LED BOARD ON NETWORK

Abstract:

The lighting device includes a LED board that supports an LED. A communication interface is provided with the LED board. At least one of a dimming control command and a color control command is received at the communication interface on then LED board. The communication interface sends the received control signals to the LED board controller. If the control signal is a dimming control command the LED board controller transmits a driver control signal to the LED driver. The driver adjusts the current delivered to the LED board based on the driver control signal. If a color control command is received the LED board controller adjusts the color of the emitted light by selectively operating different color LEDs as programmed in the LED board controller.
