LED (light-emitting diode) street lamp using double-sided radiator structure

Abstract

The invention discloses an LED (light-emitting diode) street lamp using a double-sided radiator structure. The LED street lamp comprises a double-sided radiator (103) which is molded by metal through extrusion; a mounting interface is installed on the double-sided radiator (103); an LED bulb (102) is disposed on the mounting interface; the double-sided radiator (103) is mounted on a lamp pole (108); and a lamp shell (101) which is molded by metal through extrusion or molded by plastic through die casting is disposed outside the double-sided radiator (103). The LED street lamp disclosed by the invention has the advantage of being simple in structure, low in cost and rapid and convenient to mount, use and maintain, and hard in fault magnification. According to the LED street lamp using the double-sided radiator structure, the bulb of the LED lamp, the lamp and a lighting control product are independent in production and use, therefore, production links of the LED street lamp can be greatly reduced, mass production is realized; and the LED street lamp using the double-sided radiator structure is beneficial for application and large-scale industrialization of LED energy-saving lighting products.

Description

technical field [0001] The invention relates to an LED street lamp with a radiator, in particular to an LED street lamp adopting a double-sided 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 lig...

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.
