Medical surgical lamp

Among lamps that require high stability and electromagnetic shielding capabilities, high-purity ceramics are particularly important.

Outdoor lighting

The lamp socket needs to be resistant to cold and heat, and still maintain stable insulation in a high-humidity environment.

In these occasions, the use of high-purity ceramic lamp holders for LED lighting can significantly enhance the safety and continuity of system operation and reduce operation and maintenance risks.

Four. High-temperature resistant LED lamp head solutions facilitate high-intensity lighting demands

In many extreme environments, such as steelmaking workshops, mine operations, and high-temperature laboratories, the challenges faced by LED lamps are not only the continuous output of brightness but also the need to operate stably for long periods under high-temperature conditions. For this reason, providing reliable high-temperature resistant LED lamp head solutions is particularly crucial.

This solution includes:

High-purity alumina LED lamp heads are selected

Ceramic substrates have excellent heat resistance and heat dissipation performance, which is a fundamental guarantee.

High-temperature stable interface design
