why led flood lights are broken?

When the led flood lights is broken, mainly problem is the light source and driver are not good enough. If there is a tool to detect it, you will know which one is broken. The following is the general reason why the led flood lights does not light up:

1. The power supply is broken and no electricity is supplied: the majority of the spotlights have broken power supply, and the power supply provides a stable working voltage for the light source.
There is a problem with the power supply in the process of converting alternating current into direct current, which may cause the led flood lights to not light up and flash directly. This kind of general cannot be repaired, and the power supply can be replaced directly. Of course, before you change it, you must find out the series-parallel number and current of the light source. Voltage, whether it is full watts, if you don't know how to change the power supply rashly, if you change it wrongly, it will be broken or not bright enough.
Another phenomenon is that the led flood lights can be on for a while at the beginning and then starts to flash or flashes when the light is turned on. This is mainly because the power supply components are unstable, resulting in flashing. The fundamental problem is that the quality of the power supply is too poor or the heat conduction is not good. After working for a period of time, the temperature of the power supply itself rises, which makes the components of the power supply itself unstable. In some areas, the temperature difference between winter and summer changes greatly, resulting in the working temperature of the power supply being too high or too low, and it cannot run stably. Objectively speaking, this kind of power supply is unqualified. Taste. If the power supply is broken, then replace it with a better one. If a normal quality power supply cannot be managed for two or three years, the quality will not be good. Now many power supplies have a 5-year warranty, and it is not a problem to use it for 5 or 6 years.

2. The light source is broken and the light does not turn on: check whether there is a black spot in the middle of the lamp bead sealant. This black spot is caused by two reasons. One is that the temperature of the lamp bead passes through the glue and the high temperature of the phosphor after long-term use. Another reason is that the current of the power supply is too high (this is because the power supply is unstable, or the quality of the light source may be poor), which is caused by the open circuit or necrosis of the lamp bead itself.

Ningbo Sunshinelux led flood lights use chinese sanan led chips in good quality and designed with a fin-type heat sink, which means it acts like a radiator to dissipate heat and extremely long life 20,000 hours to reduce re-lamp frequency. If you buy more than 100w, adds a respirator so that It is easier to dissipate heat, air convection, and prolong the working life of the product.

To choose a qualified led flood lights, which requires very high professionalism. Believe that Sunshinelux’s led flood lights will be your best choice.
