LED lamp is one of the lamps commonly used in life, and attention should be paid to all aspects in the use process. So, how to repair the LED light that is not lit but has weak light? What should I pay attention to when using LED light strips?
How to repair the led light that is not lit but has weak light?
Generally speaking, it is caused by some lamp beads not lighting up, such as internal damage or short circuit. If it is damaged, it cannot be repaired. The entire lamp panel must be replaced by a professional. However, if only some lamp beads are short circuited, you can find this part, remove it with a tool, and then replace it with lamp beads of the same specification.
However, this situation may also be caused by the instability of household voltage, especially in the peak period of power consumption, and can not be used normally until the voltage is restored. However, if it is caused by line damage, professionals must be required to deal with it as soon as possible to avoid water leakage and other dangerous accidents.
Precautions for using D light strip
1. High temperature damage
The LED light strip has poor temperature resistance. If the welding temperature and time are not well controlled in the production process, it is likely that the high temperature will continue, leading to LED chip damage and death. In this case, first control the temperature of the soldering iron. It is recommended to use a temperature control soldering iron to prevent the LED chip from burning out at high temperature. Note that the soldering iron cannot stay on the LED pin for 10 seconds, otherwise the LED chip will be easily burned.
2. Moisture bursts at high temperature
There is a certain amount of water in the air. If the LED package is exposed to water for a long time, the water in the LED package will be subject to thermal expansion due to excessive temperature in the over-current welding, resulting in the LED package bursting and damage. LED storage environment needs constant temperature. If the unused LED should be baked in the oven at 80 ° for 6-8 hours for dehumidification, it can ensure that the LED will not absorb moisture.
Article summary: the above is about how to repair the led light that is not lit but has weak light and all the things that need attention when using the led light strip. i hope it will be helpful to everyone.
