1. The power supply is broken, and the power supply is not connected:

The bad power supply of the floodlight of the floodlight manufacturer accounts for the majority, and the power supply shows a good working voltage for the lamp source.

(1) the power supply has problems in the whole process of converting AC current to DC power supply. It may form that the LED projection light does not flash directly, which is generally impossible to repair. Change the power supply immediately. Naturally, you have to find out the serial and parallel number of the light source, the current intensity, and whether it is full watt. If you don't figure out how to change the power supply hastily, you can't control how long it will be broken or not bright.

(2) another situation is mainly manifested in that at the beginning, the floodlight can be on for a moment, and then it starts to flash or flash when the light is on. This is mainly because the electronic components of the power supply are unstable, forming a flash. The root problem depends on the poor quality of the power supply or the poor heat transfer. After a period of time during the operation of the power supply, the temperature of the power supply itself rises, forming the instability of the components of the power supply itself, and the temperature difference in some regions changes greatly in winter and summer, The operating temperature of the power supply is too high or too low, and it cannot operate smoothly. Objectively speaking, this kind of power supply is full of unqualified products. If the power supply breaks down, replace it with a better one. If a general quality power supply can't last for two to three years, the quality will be poor. Now many power supplies have a five-year warranty period, and it's no problem to use it for five or six years.

2. The light source is broken and does not flash:

(1) check whether there is a small black spot at the gluing part in the middle of the LED lamp bead. This small black spot is caused by two reasons. First, after long-term application, the temperature of the LED lamp bead is generated by the high temperature of strong glue and luminous powder. Another reason is that the current of the power supply is too high (this kind of power source is unstable, and it may also be due to the poor quality of the lamp source). Look at the LED lamp bead itself, leading or shrinking.

(2) poor heat emission of the light source of the projection lamp will also lead to serious light loss (that is, it will not be on before) or burning. In addition, there is also a problem that the floodlight is not done well, and the water seeps inside the lamp, forming led beads and burning.

(3) if the housing is intact, it is still possible to replace the LED lamp beads, but you need to know the main parameters of the power supply, such as output power, current, operating voltage, and so on, which should be matched with the light source.
