Problems solved by technology

However, in some occasions that require high lightness of the lamp structure, such as narrow industrial and mining occasions, or occasions that require high aesthetics of lamps, such as urban municipal lighting, etc., this kind of radiator is bulky and cannot meet the design requirements of lamps. Therefore, the heat dissipation problem of high-power LED lighting equipment in these occasions still cannot be effectively solved

Abstract

The invention provides an ultra-thin radiator for an LED (light-emitting diode) lamp, and the ultra-thin radiator is made of metal aluminum. The ultra-thin radiator is characterized in that the aluminum radiator is integrally stamped and formed by double layers of aluminum boards, wherein a honeycomb-shaped pipeline is formed between the double layers of the aluminum boards by stamping; and a super-conductive medium is contained in the pipeline. The aluminum radiator can be directly used as a housing of a lamp, is various in modeling, has super-strong radiating performance, and is especially suitable for being matched with a large-power LED light source assembly for use, so that the radiating needs of a large-power LED light-emitting module are met by virtue of a simple design.

Description

technical field [0001] The invention relates to the technical field of LED lighting equipment, in particular to the heat dissipation technology of LED lamps. Background technique [0002] With the development of LED street lamp technology, high power and high lumens have become a trend, so the heat dissipation performance of the LED street lamp housing has become a technical bottleneck that limits the power increase of LED street lamps. [0003] The patent zl201520208157.3 held by the applicant himself ( figure 1 As shown), the heat-conducting copper tube 200 is used as the heat-conducting member to conduct the heat of the aluminum substrate 300 to the heat-dissipating aluminum sheet 100 to realize heat dissipation. The heat-conducting copper tube can be a superconducting copper tube with a heat transfer rate of 300,000 W / M.K, and 40 heat-dissipating aluminum sheets are used to provide heat dissipation for the 250W lamp. The use of superconducting copper tubes greatly impr...
