Description
Technical field
The present invention relates to a kind of radiator structure of LED power-type street lamp segmentation luminescence unit.
Background technology
Current LED power-type street lamp has been dispelled the heat by the whole lamp of lamp housing and has changed segmentation radiator structure into most the sixth of the twelve Earthly Branches, and each section forms an independently luminescence unit.Two Fa Guang Unit unit Jian Liu have a gap, and form the passage of heat flow, this tactic pattern is conducive to the heat radiation of luminescence unit, and LED industry competitively adopts.But independently luminescence unit in heat dissipation technology link, remain from LED lamp bead, to aluminum-based circuit board, to vertical heat transfer not smooth Ji Intraoperative difficult point aluminium radiator, so that the electric heating produced when forming LED work can not conduct smoothly, spread, thus causes the light decay of LED.
Summary of the invention
The present invention is exactly for this technology reality, provides a kind of radiator structure of LED power-type street lamp segmentation luminescence unit.It adopts solid state si heat conducting film to substitute traditional liquid heat conductive silicone grease, under producing the condition of high temperature when overcoming LED work, the technological deficiency of liquid heat conductive silicone grease highly volatile, solid state si heat conducting film is a kind of polymer composite, there is both-sided adhesive and high conduction stability, it can all the time with face contact pattern, be connected between aluminum-based circuit board and aluminium radiator, evaded heat-conducting silicone grease volatilization after caused point cantact, make the drawback of large calorimetric energy whirlpool Liu in aluminum-based circuit board.For improving radiating effect further, at surface spraying one deck heat loss through radiation coating of aluminium radiator radiating fin, improve the radiating effect of Fa Guang Unit unit further with the form of infra-red radiation.
This heat loss through radiation coating is through the solution of modified colloidal particulate (being less than 100 nanometers) the generation cohesion that high-temperature process is crossed.Solution after film-forming, in fish scale-shaped structure, is conducive to radiation of heat under the effect of curing agent, and its filler is the material of the high thermal conductance such as CNT, spinel metal oxide and infrared emission.This structure can increase heat radiation specific area and conductivity greatly, improves the radiation coefficient of radiating fin infra-red radiation, significantly promotes the effect of Re Liang Jiao Change.
