LED road lamp using extruded radiator as main lamp structure

Abstract

The invention discloses an LED road lamp using an extruded radiator as a main lamp structure. The LED road lamp comprises the metal extruded radiator (103) and a harness connector (106), wherein the metal extruded radiator (103) is formed by an extrusion process, is fixed onto a lamp post (108) and comprises a lamp post fixing sleeve. Radiators are arranged on two sides of the lamp post fixing sleeve, mounting interfaces for mounting LED bulbs (102) are arranged on the radiators, and the LED bulbs (102) are mounted on the mounting interfaces. The harness connector (106) is arranged on the lamp post fixing sleeve and used for connecting the LED bulbs (102) into a power supply and a control circuit. The LED road lamp is simple in structure, low in manufacturing cost and rapid and convenient to mount, use and maintain. Faults are not easily enlarged, the bulbs of the LED lamp, a lighting fixture and a lighting control product can be respectively independent in production and use, production links are greatly decreased, batch production is improved, and application and industrial scale expansion of energy-saving LED lighting products are facilitated.

Description

technical field [0001] The invention relates to an LED street lamp, in particular to an LED street lamp using an extruded radiator as the main structure of the lamp. 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 l...

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.
