How to deal with the power failure of LED floodlight

The power supply is the basic reason why the lamps are broken. The power supply provides the constant current working voltage for the light source. Many led floodlights are broken in the power supply. The power supply is broken. It can't be repaired. So what should I do if the LED light is not powered?
 
 
If the power supply of the floodlight is good, the performance is that the floodlight can be on for a while at the beginning and then start to flash. This is mainly because the heat of the lamp beads cannot be dissipated, resulting in continuous flash. The fundamental problem is that the shell does not scatter the lamp beads of the light source. First, check whether the shell meets the standard of 50g / W, in addition, check whether the light source is well connected with the shell, and whether the heat transfer paste is evenly coated.
 
 
 
If the power supply is broken, try changing the power supply to see if the light is still off. If not, then the problem is not necessarily in the power supply. Another reason is that the temperature difference between winter and summer varies greatly in some areas, which causes the working temperature of the power supply to be too high or too low and cannot operate stably. Objectively speaking, the power supply is all unqualified. If the power supply is broken, replace it with a better one. The quality of a power tube will not be good until two or three years.
