LED street lamp with extruded heat sink structure

Abstract

The invention discloses an LED (light-emitting diode) road lamp adopting an extruding radiator structure. The LED road lamp comprises an extruding radiator (103) formed by metal in an extruding manner; the extruding radiator (103) is provided with an installing interface; the installing interface is provided with an LED light bulb (102); the extruding radiator (103) is installed on a lamp post (108); a lamp shell (101) formed by metal in a punching manner or formed by casting plastic is arranged outside the extruding radiator (103); the LED road lamp adopting the extruding radiator structure further comprises a harness connector (106); and the harness connector (106) is used for distributing and connecting the plurality of LED light bulbs (102) into a power supply and a control circuit. According to the LED road lamp adopting the extruding radiator structure, the LED road lamp is simple in structure, low in construction cost, rapid and convenient to install, use and maintain without worsening breakdown, so that the production and use of the light bulb of the LED lamp, the lamps and the lighting control products are independent, the links in the production chain are greatly reduced, the mass production is realized, and the application and large-scale production of the LED energy-saving lighting products are benefited.

Description

technical field [0001] The invention relates to an LED street lamp with a radiator, in particular to an LED street lamp adopting an extruded radiator structure. Background technique [0002] As a new generation of lighting technology, semiconductor lighting has high photoelectric conversion rate, easy control of light source direction, easy control of lighting period and mode, high color rendering of light source, high power factor under reasonable design, etc., which cannot be compared with other existing lighting technologies. The five energy-saving advantages are favored by global investors and strongly supported by governments of various countries. The luminous efficiency of current LED lighting can exceed 70LM / W, which is more energy-saving than traditional energy-saving lamps. Theoretically, the luminous efficiency of green LEDs can be as high as 683LM / W; the theoretical efficiency of white LEDs can also reach 182.45LM / W, so there is huge room for improving LED lighti...

AI Technical Summary

Problems solved by technology

This has brought a series of fatal problems such as high manufacturing cost, inconvenient use, and difficult maintenance to LED lighting products.

First of all, it is impossible to achieve national and even global unified standardized production in manufacturing, resulting in many product specifications, few batches, and high prices; secondly, the products of each company are various, not universal, let alone interchangeable; thirdly, product failure Sometimes it is necessary to remove the LED optical module, driving power supply, lamps and other assemblies as a whole for maintenance, which is extremely inconvenient to maintain, and it is very easy to cause defects such as expansion of faults, delay in maintenance, and high maintenance costs.

These defects have greatly restricted the promotion and use of LED lighting, and are flaws in the promotion of LED lighting products.
