ABSTRACT:
A high-illumination lighting system for microwave ovens which employs a small, low-voltage microwave-immune incandescent lamp located within the oven cavity, thereby utilizing up to the full 4.pi. steradians of emitted light. The lamp, which may be integrated into the oven cavity during manufacture or may be included in aftermarket ovens as a complete lamp module, preferably is located at the upper front of the oven in order to front-light the over contents. The lamp may be electrically connected to one of several existing oven power supplies, or alternatively, may be an aftermarket module powered by microwave energy within the oven cavity. In the latter case, a microwave antenna is connected to the lamp to supply operating power.
