Caution: 

 First, heat, light-emitting diode semiconductor chip due to the current technical limitations, LED conversion efficiency to be improved, especially the great merit LED, because of higher power, about 60% of the energy will become heat release, which requires end-user in the application of high-power product, heat to do work to ensure that high-power LED products to work properly. 
 Second, the electrostatic protection, LED are semiconductor devices sensitive to static electricity, especially for white, green, blue, purple, LED to do the work to prevent static electricity and eliminate static electricity. 
 Third, welding, soldering iron temperature, please pay attention to selecting the welding temperature of 260 degrees Celsius.
