Description

Profile, LED street light body, LED street light

LED street lights not only have good color, maintenance-free, long life, but more importantly, they are more energy efficient than traditional street lamps. LED street lights replace traditional street lights and are a revolution in public utilities. At present, high-power LED street lamps are in the stage of trial or trial production, and many international lighting giants are also involved in high-power LED street lamps, but almost no formal application. The tester or the tester often uses a lamp body similar to a normal street lamp to dissipate heat with the fan. The cooling of the fan is not only unstable, but also has a low life, energy consumption and frequent maintenance. Moreover, the structure of the traditional street lamp, regardless of the metal stamping or the die-casting lamp body, requires a special mold to process each type of product, which invisibly increases the manufacturing cost and limits the promotion and application of the high-power LED street lamp.
