Description

Technical Field

[0001] The utility model relates to the field of street lamps, and more specifically, to a multi-lamp head active heat dissipation type LED street lamp. Background Art

[0002] With the continuous advancement and maturity of LED technology, LED street lights have gradually become the mainstream choice for road lighting. The energy consumption of LED street lights is much lower than that of traditional street lights. Since LED light sources have high luminous efficiency, LED street lights consume less power than traditional street lights under the same lighting effect. In addition, LED street lights do not contain harmful substances, are more environmentally friendly, and are in line with the concept of modern green lighting.

[0003] Existing LED street lights have only one or a few lamp heads, which limits the lighting range of street lights. In some areas that require extensive lighting, such as large squares, stadiums or highways, the lighting range of a single lamp head may not be enough to cover the entire area. In areas with heavy vehicle traffic at night, more lamp heads may be needed to illuminate the road to improve driving safety. In the case of a limited lighting range, there may also be lighting blind spots, and unlit areas may cause safety hazards. Street lights generate heat when working, especially LED street lights. If the street lights do not have the function of autonomous heat dissipation, the heat will accumulate inside the lamp head, causing the internal temperature to rise. Continuous high temperature will not only affect the performance of the street lights, but also shorten their service life. When installing some street lights, it is inconvenient to route the wires, the cable management is inconvenient, and even messy. Not only does it increase safety hazards, it may also cause trouble during maintenance. It may take more time and effort to organize the cables. Utility Model Content

[0034] During the specific installation, first fix the mounting rod to the lamp pole, then insert the L-shaped lamp holder rod into the jack of the top cover unit, and insert it into the U-shaped limit plate, so that the plug is inserted into the lamp holder rod until the bottom end of the lamp holder rod abuts against the abutment plate, then fix the lamp holder rod with the first locking bolt, then the surrounding plate of the top cover unit surrounds the top of the mounting rod, and fixes the top cover unit with the second locking bolt. When threading, thread the wire from the rubber tube. Since the rubber tube has a certain elasticity, the gap of the rubber tube is smaller after threading, which reduces the waste of heat dissipation airflow caused by the heat dissipation airflow flowing out of the threading hole.
