How long will the led light last? what if the LED light doesn’t work?
Led light does not light how to change itself first, turn off the switch, with the help of folding ladders, remove the shell of the led ceiling lamp, and check whether the lamp tube is dark. If so, it is likely that the lamp has been damaged.
At present, the service life of our LED lamp is 30, 000 hours, but what you need to know is that 30, 000 hours is not that the light is broken or not on.
Theoretically, the service life of LED lamps (light emitting diodes only) is generally 10000 hours. However, after assembling the lamps and lanterns, because other electronic components also have a life, the LED lamp can not reach 10000 hours of service life, generally speaking, it can only reach 5000 hours.
After the installation of the LED light bulb is not lit, the plug power supply is normal, change the light bulb. If it is the LED headlamp assembly, it is generally the headlight control unit problem, if the control unit has electricity, the iron is normal, and the plug is not corroded, it is to change the headlamp control unit and replace the headlamp control unit.
How is the led light sometimes on and sometimes off?
The possible reasons are as follows. The power supply system is unstable. A part in the power supply circuit for the LED lamp is damaged. The power switch that controls the LED lamp is not in contact with reality. Solution: restart the power supply system again to see if the LED light is normal. Send the lamp to the repair station to repair or replace the LED lamp.
Due to the heating condition, the virtual welding occurs in the LED power supply. Check whether the LED lamp circuit is in bad contact, and you should find a professional for door-to-door maintenance. Check if there is a problem with the bulb of the LED lamp. The bulb should be changed immediately. Check whether the voltage at home is too low, find a professional door-to-door inspection in time.
There are two reasons why LED lights are not lit: first, the excessive leakage current of LED causes PN junction failure, so that LED lights are not lit, which generally does not affect the work of other LED lights; second, the internal connection leads of LED lights are disconnected, resulting in dead lights caused by no current passing through LED.
What are the reasons why the LED light is not on?
The reasons why the LED is not bright are as follows: the packaging protection of the LED lamp strip is not perfect, which causes the lamp beads to be damaged by impact during transportation. The solder joint of the LED lamp strip has the phenomenon of virtual welding, and the vibration in the process of transportation will cause the solder joint to fall off and cause the lamp belt to be not bright. The solder content of LED lamp strip is small, and the solder joint is easy to fall off.
The possible reasons are as follows. The power supply system is unstable. A part in the power supply circuit for the LED lamp is damaged. The power switch that controls the LED lamp is not in contact with reality. Solution: restart the power supply system again to see if the LED light is normal. Send the lamp to the repair station to repair or replace the LED lamp.
The reason why the led light is not lit and the maintenance power supply voltage is low: check whether the switch and socket are connected properly, if it is found that the connection is normal, it may be due to insufficient power supply, at this time, you need to check whether the line has bad contact or short circuit; if there is no fault, then you need to replace a new power cord.
