If the spotlight is used for a period of time and it is not bright when it is just bought, then the situation is that the light source is of poor quality and the light decay is severe. The spotlight will be darker as the time of use. So today, Xiaobian will take everyone to analyze the reasons for the LED floodlights not shining.

The poor heat dissipation of the floodlight source will also cause the light source to decay (that is, it has not been lit up before) or burn out. In addition, there is no waterproofing of the floodlights, and the water inside the lamp is burned, causing the lamp beads to burn out. If the outer casing is intact, it is still possible to replace the lamp bead, but you need to know the power, current, voltage and other parameters of the power supply, and match the light source.

Wire solder joints are soldered, resulting in no power: the integrated lamp in the floodlight is connected to two wires. Does the lamp have any solder joints, false soldering, cold soldering, whether the power input line has loose connection points, open circuit, etc. Is the drive cable broken?

The floodlights went into the water. This kind of waterproof treatment is not done well, and the consequences may cause the light source and the power supply to burn. This kind of basic is not saved. You can change the light source and the power supply if you know it better. If necessary, you can contact the factory for sale. The main reason is still The quality is not good.
