however, the LED Module

 Furthermore, as device dimensions continue to shrink , screen size and resolution graphic  LED Bulb printing has its limitations , as the reduced size , screen printing rendered image size differences of each unit ( uniformity ) and the metal thickness difference will be more obvious. In order to be able to continue to shrink circuit size and accuracy of the stringent requirements , LED heat sink substrate production technology is bound to continue to improve. Thus the introduction of thin film technology has become one of the ways to improve , however, the  LED Module country has a mature film metallized ceramic substrate process technology manufacturers are numbered. To this end, started to film element Secretary Bo Ai E (ICP), that is, for the development of their own traditional thick film substrate and substrate process and product characteristics of its variance analysis ( as shown in Table II ) .

LED is based on the principle of electroluminescence solid semiconductor light source, with rich colors , compact size , high brightness , long life , low voltage , safe to use , fast response , adjustable from 0 to 100% light output , impact resistant anti-vibration , no ultraviolet and infrared radiation , and many other advantages . Therefore, the gradual expansion of the range of applications and has good application prospects. LED Flexi Strip

Single high-power high-brightness LED package of high cost, and is mainly a point source, so close to a wide range of practical still time . Currently into practical use single high-brightness LED power is very small, but most of the actual use of the occasion requires flat light, it must be arranged in accordance with the requirements of multiple LED combination , on the one hand to meet a wider range than high brightness, dynamic display, color-changing requirements of applications such as hand to meet with the LED driver matching driver matching requirements .
