Description
Technical field
The invention belongs to high-power illumination lamp technical field, relate to the illumination lamp of being with heat abstractor, particularly relate to a kind of cross-ventilation radiating high-power LED road lamp.
Background technology
LED (Light emission diode light emitting diode) obtains the approval of society and increasingly extensive application with its energy-efficient, safe and reliable, long-life superiority in recent years, wherein, the most important thing is the appearance of super brightness white light great power LED, make the application of LED be across to efficient road lighting from the lamp of giving instruction, instrument board.But the solid matter of great power LED is used simultaneously, and the drawback of light fixture ubiquity sealing, causes the difficulty of distributing of heat, the service life of seriously having reduced LED.
Solve this drawback, must solve the heat dissipation problem of light fixture.There are a lot of patent documentations to disclose LED light fixture heat sink conception, what generally adopt in existing technology is to utilize lamp chamber air fluxion strap to walk heat, improve heat radiation, its scheme adopts the heat radiation chamber, there is air inlet/outlet in the heat radiation chamber, communicates with atmosphere or directly communicates with atmosphere by conduit, and air inlet is arranged below conduit, there is the gas outlet top, and the heat radiation chamber is formed by the fin sealing.Its weak point is owing to adopt one or two radiating tube to serve as the heat radiation chamber, the area of air and radiating tube heat exchange is big inadequately, the heat of taking away when air flows is few, make heat exchanger effectiveness not high, in addition, the heat radiation chamber is a closing form, and air advances one by one of radiating tube and goes out, and the thermal capacity that makes air take away is little.
Causing another too high major reason of luminous zone temperature is that high-power LED light source and radiator assembling are unreasonable, be at first the high-power LED light source array to be welded on the FR4 epoxy resin wiring board in existing high-power LED light source and radiator mounting technology, wiring board relends the hot silica stationary of the assistant director of a film or play on fin then, because the heat transfer efficiency of epoxy resin wiring board and heat conductive silica gel is lower, cause the thermal impedance between high-power LED light source and the fin to increase.
Above-mentioned deficiency all is the main cause that causes decay of high-power LED light source light efficiency and reduction in service life.
