What are the main faults of the LED desk lamp light source not turning on?
We all know that table lamps are very common in our lives, and they can be used for home decoration, student study, office supplies and other life needs. But LED desk lamps occasionally have some faults, so what are the reasons for the faults? Let's follow the eye protection lamp manufacturers to discuss and refer to.
Generally, there are two types of LED desk lamps, one is a USB rechargeable LED desk lamp, and the other is a battery-guided LED desk lamp.
About the cause of the failure of the USB rechargeable LED desk lamp light source
1. The USB socket is damaged and has no power, resulting in the failure to charge;
2. The fault of the charging circuit;
3. Turn on the light while charging, causing the wick of the LED tube to burn out.
About the cause of the failure of the LED desk lamp led by the battery not to light up
1. The circuit board seems to be in good condition, but many inspections will find that there are breaks;
2. The battery is dead or the circuit is in poor contact, so it cannot supply power;
3. The LED is burned out due to excessive current. (In order to make the light brighter, some manufacturers design the current of the LED to be too large, which greatly shortens the life of the LED. In this case, the LED is often dimmed to not bright.)
