AI Technical Summary

Technical Problem

Existing lighting fixtures are difficult to use and prone to damage when adjusting the direction of light, especially when users want the light to shine at an angle, the components of the fixture are inconvenient to adjust and easily damaged.

Method used

A universal joint unit is used to connect the heat sink housing and the insulating housing. The orientation of the light-emitting device is adjusted by rotating the heat sink housing, and the gap is sealed by the flexible housing. Ball pins and limiting grooves are set to facilitate installation and disassembly, while guiding the wires to avoid damage.

Benefits of technology

This invention achieves ease of use and high reliability of the lighting device, allows for adjustment of the light direction within a wide angle range, prevents foreign objects from entering, reduces wire damage, and improves the overall reliability and service life of the device.
