LIGHTING FIXTURE CONNECTION ASSEMBLY
A lighting fixture includes a driver, a heat sink assembly, a light generating assembly, a first connection assembly, and a first lead. The heat sink assembly is coupled to the driver and includes a base plate that defines a first through hole. The light generating assembly is secured to the base plate and includes a PCB, a plurality of LEDs, and a board cover. The PCB defines a first board hole therethrough. The plurality of LEDs are secured direction to the PCB. The board cover is positioned over the PCB and is fastened to the base plate. The first connection assembly includes a first connector that is secured directly to the PCB and that is in electrical communication with the plurality of LEDs. The first lead extends from the driver, through the first through hole, through the first board hole, and being captured by the first connector.
