The Thermal Management For The LED

Time:2014/9/23  keywords:LED Street Light


      Relative to the traditional light source, LED has longevity, echo strength such as fast, high photosynthetic efficiency and environmental protection.But the  led high bay   common technical problems still exist - heat dissipation.If there is no outstanding heat capacity, the quantity of heat of chip scattered not to go out, and will make the chips produce light failure will affect its service life.

      LED by electronic before the onset of the transition between the band, infrared light is not included in the spectrum, the LED heat out not by radiation, and thus LED called cold light source.LED generally choose epoxy resin encapsulation, the thermal conductivity of epoxy resin ability is very poor, heat can only rely on the chip substrate from the pin.Traditional brightness LED as luminous power, quantity of heat also is not big, so no cooling.While power type LED in lighting demand will more than to reach the required luminous flux of LED light source module, chip and more concentrated, will produce a lot of heat, if not timely to heat conduction, will directly affect the performance of the chip.

      In today's  LED Street Light   chip high integration density, heat yield high, existing cooling device on heat conduction link, ignoring the convection radiator link, although many manufacturers thought for all kinds of ways to improve heat transfer link, but the export quantity of heat is not dispersed in time will reflow heat, need the air to optimize the structure of the cooling fins increased contact area, scientific use of air thermodynamics, rather than blindly increasing radiator for cooling volume.
