Description

Technical Field

[0001] The utility model relates to the field of street lamps, and more specifically, to an LED street lamp with convenient illumination angle adjustment. Background Art

[0002] The development of streetlights is closely tied to the progress of human civilization. From ancient campfires to modern LED streetlights, streetlight technology has continuously innovated, and lighting performance has continued to improve. With technological advancements and growing environmental awareness, LED streetlights are becoming mainstream due to their high efficiency, energy saving, and environmental friendliness.

[0003] Many traditional streetlights have fixed lamp holder angles, which limits their flexibility in complex environments (such as ramps, curves, and squares), making it difficult to achieve optimal lighting results. While some streetlight lamp holders have adjustable angles, they often fail to maintain the set angle after adjustment. Wind, vibration, and other factors can cause them to loosen, impacting lighting quality and safety. Furthermore, due to the varying lighting angle requirements for different road conditions, some lamp holders are difficult to adjust. Furthermore, the lamp holder's adjustment mechanism is exposed, without a protective structure. Environmental factors such as rain can damage it, shortening its service life. The exposed adjustment mechanism also affects the streetlight's appearance. Utility Model Content
