Image Number 5 for United States Patent #7874690.
An oven lighting fixture includes an LED assembly or assemblies optically coupled with an optical guide member. The lighting fixture also includes a mounting bracket and a pair of electrical leadwires to connect the LED lighting fixture to an external voltage source. The LED assembly has an LED attached to a printed circuit board containing ancillary circuitry for powering the LED, and a heat sink for removing heat from the LED. The mounting bracket is attachable to a door of the oven cavity to support the LED lighting fixture adjacent to a sidelight window. The mounting bracket has a slot adjacent to the window for transmitting light from the LED through the light guide and into the oven cavity. Positioning the lighting fixture outside of the oven cavity and adjacent to the sidelight window permits the LED to operate within required temperature limits.
