(1) At present, most LED tunnel lights still use high-power integrated light sources, the heat is concentrated and unevenly distributed, and the heat dissipation capacity of the lamps is poor. raised and shortened.
(2) At present, LED tunnel lights on the market are generally assembled with light source modules, power supplies and lamp housings. The lamp structure is complex and the operation is cumbersome.
(3) On the existing LED tunnel lights, the common connection method between the lens and the lamp housing is to use screw connection. Although a seal is set between the lens group and the lamp housing, the sealing performance of the screw connection is relatively low. Difference. Specifically, when the screw connection is used, the torque of each screw in the screw group is not exactly the same when tightening, so that the deformation of the seal is different, resulting in uneven small gaps between the seal, the lens and the lamp housing, and the water vapor It is easy to penetrate into the cavity of the lens and the lamp housing from a large gap, which affects the luminous performance and electrical performance of the LED lamp beads between the lens and the lamp housing, thereby affecting the service life of the lamp.
