What are the main parameters of LED high -power lamp beads? 1cd = 1 lm/sr (flow/three -dimensional arc) = 1 candlelight. The interpretation is: the optical flux issued from the three -dimensional angle DΩ in the specified direction or the optical flux Dφ transmitted by the light source transmission, the business of the two is the light emitting intensity I (the unit is Kandla, CD).

LED high -power lamp bead

The outer hood can be made of PC tube. The high temperature resistance is 135 degrees .PC tube to make LED hoods. The inner temperature can reach 135 degrees. The outer temperature can resist -45 degrees without cracking. As a new green, environmentally friendly, energy-saving light source , Flashlight, lamps and other places. The name of LED high power is mainly for small power LEDs. There are three types of classification standards:

The first of these types can be divided into 0.5W, 1W, 3W, 5W, 10W .... 100W according to the power size. According to the total power of the molding product after packaging, it is different and different.

The second type can be divided into different packaging processes: large -sized epoxy resin packaging, imitation of mermaid epoxy resin packaging, aluminum substrate (MCPCB) encapsulation, to packaging, power -type SMD packaging, MCPCB integrated packaging, etc.

The third type can be divided into low -light power products and non -low light aging power products according to its degree of light decay.

Of course, because there are many parameters of the high -power LED itself, there will be different classification standards according to different parameters, and there will be no more described here.

LED high -power lamp beads still belong to one of the LED packaging products, which is the most important part of semiconductor lighting towards the general lighting field.
