LED split type module lamp

Abstract

The invention discloses an LED split type module lamp which comprises a light management module, a light source module, a heat-radiating module and a housing, wherein the housing is provided with a cavity structure with an opened side, the heat-radiating module is arranged in a cavity of the cavity structure, a penetrating structure communicated with outside is arranged on the wall of the cavity,the light source module is fixed with the heat-radiating module, an emergent light side points at the opened side of the cavity, one end of the light management module is connected with the housing through a hinge mechanism and enables the light management module to rotate around the hinge mechanism for covering the opened side so as to cover and buckle the light source module, and the other end of the light management module is fixed with the housing through a wrench buckle. The power drive module, the light source module, the heat-radiating module and the light management module are subjected to split module design, thus the LED split type module lamp is easy to disassemble and replace, and is easy to realize expansion application of a large-power LED split type module lamp.

Description

technical field [0001] The invention belongs to the field of semiconductor lighting and relates to an LED split-type module lamp. Background technique [0002] The light source commonly used in the current road lamps is a high-pressure sodium lamp or a metal halide lamp, but there are certain deficiencies in the illuminance of the road surface and the uniformity of the illuminance. With the continuous advancement of human lighting technology, the industry has gradually begun to use LEDs as street light sources. In the field of semiconductor lighting technology, LED, as the fourth generation of energy, has the following advantages: high luminous efficiency, low reflection loss of lamps, energy saving, no need for high voltage, high safety, and long life, etc. [0003] However, heat dissipation has always been one of the key problems to be solved for LED street lights. Due to the high brightness requirements and high heat generation of LED street lights, and the harsh outdoor...

AI Technical Summary

Problems solved by technology

However, at present, most manufacturers only consider the heat dissipation surface area required by the LED light source when designing LED street lamps, and do not consider the environmental factors in the actual application of LED street lamps. This will cause large particles of dust, Leaves, paper scraps, woven fabrics, bird droppings, etc. accumulate on the heat sink of the lamp body in large quantities, and it is difficult to wash away even if there is rain. This will cause the heat generated by the LED light source to not be dissipated in time, so that the junction temperature of the LED light source will rapidly increase. increase, the luminous decay is accelerated, and the luminous flux drops sharply, which not only affects the illumination requirements of the road surface, but also greatly reduces the service life of the LED split module lamps

[0005] In addition, the existing LED street lamps often use an integrated design, which is not easy to disassemble during use, which brings great difficulties to maintenance
