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

Abstract

The invention discloses an LED street lamp adopting a double-sided radiator structure, which comprises a double-sided radiator (103) formed by extruding metal. The double-sided radiator (103) is provided with an installation interface, and an LED is arranged on the installation interface. The light bulb (102); the double-sided radiator (103) is installed on the light pole (108); the double-sided radiator (103) is provided with a metal extrusion molding or plastic die-casting molding lamp housing (101). The invention has the advantages of simple structure, low cost, fast and convenient installation, use, and maintenance, and will not expand faults. It realizes the independence of production and use of bulbs, lamps, and lighting control products of LED lights, greatly reduces production links, and realizes production The mass production is conducive to the application and industrial scale 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...

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.
