Description

Technical Field

[0001] The utility model relates to the technical field of LED street lamps, and more specifically, to a lamp housing for LED street lamps. Background Art

[0002] LED street lights refer to street lights that use light-emitting diodes (LEDs) as light sources. LED street lights are efficient, safe, energy-saving, environmentally friendly, have long life, fast response speed, and high color rendering index, which are of great significance to energy saving in urban lighting. At present, when LED street lights use traditional street lamp housings, most of them are fixed and installed with screws, which means that when the electronic components inside the lamp housing need to be replaced and repaired, tools are needed to disassemble them, which affects the maintenance efficiency. In addition, the screws are small, and if they fall, they are difficult to find, which affects the normal installation. When connecting to external lines, the cables are generally directly inserted into the wiring holes for installation. This wiring method is relatively simple, and the cable fixing effect is poor, which is prone to random shaking, resulting in poor contact. Moreover, most of the lamp housings are one-piece structures and do not have a buffer mechanism, which causes hail or gravel lamps to fall from above, causing damage to the lamp housing.
