Want to improve the efficiency of the LED display, extend the life of the LED display, it is necessary to solve the LED heat problem, I hope we must take seriously.
 
         A fever principle:
   
       Simply means that the power input of only 20% LED display --30% conversion of light energy, and the remaining 70 percent into heat energy consumed only by conversion, so the LED display on the very high fever.
 
        The above simple understanding a little fever principle, to talk about the cooling method are highlighted below it.
 
        Second, the cooling package is divided into before and after packaging
   
        Front Package: Led chip and heat, mainly the selection and technology related to the substrate and the circuit, as any LED lamps are made, so the heat generated by the LED chip always end by the lamp housing scattered into the air. If the heat is not good, because the heat capacity of the LED chip is small, a little bit of accumulation of heat will make the chip junction temperature is rapidly increasing, if a long time in a high temperature state, its life will soon be shortened.
 
        After the package, that is, we can operate the cooling mode:
 
       1, thermal plastic case: a thermally conductive material at the time of filling plastic injection molding, plastic housing increased thermal conductivity, heat capacity.
 
       2, air hydrodynamics use of the lamp envelope shape, to create a convection air, which is the lowest-cost way to enhance heat dissipation.
 
       3, a fan or blower inside the lamp housing reinforcing long life and efficient cooling fan, low cost, good effect. But some want to change the fan is in trouble, not suitable for outdoor, this design is more rare.
 
       4, the use of a heat exchanger tube heat exchanger tube technology, the heat conduction from the LED chip to the housing fins. In large lamps, such as street lamps is a common design.
 
       In short, according to the implementation of the above approach, your LED display will dramatically improve the efficiency and service life!
