1. Try to use the form of series LED, because the voltage difference of LED floodlights is special. The peak current of ordinary LED is maintained at 80mA, and the reverse voltage is around 6V. In LED application, attention should be paid to the limit of peak voltage and current in circuit design.

2. Use soldering at 25 watts, the soldering iron is individually controlled to be exposed to the SMD LED at a high temperature of 300 degrees Celsius, do not squeeze its epoxy resin part, the LED floodlight or wipe it with a sharp object, because the LED light is very fragile and easy to use Damaged, welding time 3 seconds. in the case of
