Abstract: A programmable LED constant current driver circuit for driving LEDs at constant current and dimming the LEDs using standard, off-the-shelf dimmers is provided. The current driver circuit of the present disclosure includes a temperature compensation feature which controls the on time for the LEDs based on a measured temperature of the current driver and associated circuits. In another embodiment, the current driver circuit is designed to receive a 24 VAC input and drive one or more LEDs in a transformer-based system dimming system.

Abstract: An LED based module designed to be easily retrofitted into existing incandescent based light fixtures with minimum or no modification is provided. The LED module of the present disclosure includes a generally cylindrical threaded adapter module including a flat top surface and a conical bottom portion. The bottom portion includes a threaded cavity for receiving a conventional threaded rod of a light fixture which then couples the LED module to the light fixture. The top surface of the LED module is configured to mount a metal core printed circuit board including at least one LED (light emitting diode). Furthermore, the LED module includes at least two channels running therethrough to accommodate wires or conductors from the light fixture to the metal core printed circuit board. The threaded surface of the LED module is configured to accept a conventional shade retainer ring or nut.
