The shunt regulator is in a parallel-type configuration with the voltage divider and is configured to receive the reference voltage and control a driver output of the LED driver based on the reference voltage.

Abstract: A lighting assembly is provided having a housing supporting a lighting source such as a plurality of LEDs, a reflector having a central opening for the light source, a light transmitting cover and a frame attached to the housing to couple the frame and the light transmitting cover to the housing. The reflector has an outer perimeter with a channel formed in the top face and the bottom face for a continuous seal member. The frame is coupled to the housing to capture the frame and the light transmitting cover between the frame and the housing so that the seal members form a weatherproof seal between the light transmitting cover and the frame and between the frame and the face of the housing.
