As lights and other auxiliary lighting source application the multiple Φ5mm package a variety of monochrome and white LED assembly on a lamp panel or standard lamp holder, the service life can reach 100,000 hours. 2000 studies have pointed out the white LED work 6000h in Φ5mm, its intensity has been reduced to half its original. In fact, the use of Φ5mm white LED array light-emitting device, its life may be 5000h. Different color LED light attenuation at different speeds, the slowest which red, blue, green center, white fastest. Used only for indicator LED original Φ5mm package, package thermal resistance up to 300 ° C / W, can not be fully heat dissipation, resulting in elevated temperature of the LED chip, causing the devices optical attenuator accelerated. In addition, the epoxy yellowing will reduce the light output. High Power LED generated in the high current white LED is 10 to 20 times more luminous flux than Φ5mm effective thermal design and the use of packaging material does not deteriorate to solve the problem of bad light, shell and tube, and the package has become the development of high-power LED one of the key technologies. New LED power-type packaging design concept mainly grouped into two categories, a class of single-chip power package, and the other for multi-chip power package.
