Abstract

A lighting fixture that includes a frame, a heat sink assembly, an LED assembly, and a reflector. The frame includes a first end plate and a second end plate, each end plate including a slot formed therein. The slot extends from a top edge of the end plates towards a bottom edge of the end plates. The heat sink assembly includes one or more LEDs and a lightguide having a first longitudinal edge that receives light emitted from the LEDs. A first edge and a second edge of the lightguide are slidably inserted into respective slots. The heat sink assembly includes a heat sink base and a heat sink cap coupled thereto which forms a first cavity for housing the LEDs and a second cavity adjacent the first cavity for housing a portion of the lightguide. The reflector is coupled to the end plates.
