1. Use the series led form as far as possible, because the LED floodlight lamp voltage difference is special. The peak current of the ordinary LED is maintained at 80 ma, the reverse voltage is up and down in 6V, in the LED application should pay attention to the design circuit peak voltage and current at this limit.
2. The use of 25 watts under the welding voltage, soldering iron temperature under 300 degrees Celsius in the high temperature of the bare SMD led, do not squeeze its epoxy parts, or with a sharp hard object to wipe, because LED lamps are very fragile, very easy to damage, welding time 3 seconds.
LED floodlight is widely used, so the installation of tips and precautions is very important, LED is a new light source, in the correct installation mode, to ensure that led floodlight stable long-term normal work.
