AI Technical Summary

Technical Problem

Conventional LED lighting devices suffer from low structural strength, particularly at the open end of frames with a roughly L-shaped cross-section, leading to deformation and tilting due to the weight of the device and the load from wiring, creating gaps between the lighting device and the fixture body.

Method used

The lighting device incorporates a frame with a protruding wall and a cover member that projects from one side, along with a fall prevention structure to enhance rigidity, and a reinforcing member to prevent the protruding wall from falling over, thereby increasing the overall structural integrity.

Benefits of technology

The solution results in lighting devices and fixtures with enhanced strength and stability, preventing deformation and tilting, ensuring a secure attachment to the fixture body.
