Support has a first mounting part and a second mounting part.Heat sink is arranged at the first mounting part. Light board is arranged on the side of the radiator facing the inside of the support. Glass cover is arranged on the second mounting part; the light board is facing the glass cover . The beneficial effect of the utility model is that the lamp board is facing the glass cover, and the high-temperature cavity is illuminated through the glass cover, so as to realize the lighting requirement. The light board is connected with the radiator to ensure the low temperature operation of the light board, and combined with the glass partition to separate the glass cover and the light board into multiple air layers with temperature differences, the air in each layer is convective with the outside through the ventilation holes. Achieve a good temperature insulation effect.
At the same time, the reflector can improve the light utilization rate. With this LED module, it can be used in high-temperature supply devices such as ovens and microwaves.
