AI Technical Summary

Technical Problem

Existing infrared emitters have low beam concentration when emitting infrared light, resulting in insufficient infrared output efficiency, which affects long-distance transmission performance. Furthermore, they are prone to overheating during high-frequency operation, affecting their service life.

Method used

It adopts a condenser lens and heat-conducting pin structure. The condenser lens reflects lateral infrared light to the optical axis direction through the reflective coating on the inner wall of the lens tube. The heat-conducting pin dissipates heat quickly through the heat-conducting plating layer. The combination of copper conductive pins and heat-conducting sheets improves heat dissipation.

Benefits of technology

It improves the concentration and long-distance transmission performance of the infrared beam, reduces the junction temperature of the infrared emitting chip, and extends its service life.
