Description

Technical Field

[0001] The utility model relates to the field of street lamps, and more specifically, to an LED street lamp based on multi-dimensional lighting angle adjustment. Background Art

[0002] Streetlights primarily illuminate urban roads, providing illumination at night or during low-light conditions. They not only impact traffic safety but also the aesthetics of cities and the quality of life for residents. LED streetlights, with their energy-efficient design, long lifespan, and diverse lighting effects, are playing an increasingly important role in urban lighting systems. With the continuous advancement of technology, LED streetlights are poised for even greater growth.

[0003] Existing streetlights often have fixed lamp heads at specific pitch angles, unable to adjust according to actual needs. This can result in suboptimal lighting in some situations, failing to fully illuminate the area in need, and potentially creating blind spots. Some streetlights also often have fixed left-right angles, limiting their illumination range and making them unable to adapt to changing road sections or lighting needs. These blind spots and limited illumination range can increase the risk of traffic accidents, especially at night or in poor visibility. Utility Model Content
