1. Quality

　　Under normal circumstances, the life of the led strip is very long, and there is no problem with the life span of more than 100,000 hours. If the damage caused by other reasons is excluded, then the product quality is defective. The main quality reasons are: the lamp beads of the strip The quality is too bad; the resistance is used to digest the high voltage and cause damage to the LED lamp beads; the irregular lamp chip is used; Jedver has three R&D teams of self-power supply + control system + lamps, and the quality is very good.

　　2. Welding

　　If the bending angle is too large when installing the wardrobe light strip, the LED light strip will not light up due to the separation of the solder joints and the copper foil. Similarly, excessive squeezing of the light strip will also cause the LED light strip chip to be damaged or The solder joint is deformed and falls off and does not shine.

　　Three, voltage

　　If the voltage of the light strip is too high or too low, it will reduce the life of the lamp beads, and the low-voltage light strip needs an external power transformer. When the internal current is too high and the power is too high, the internal heat can not be dissipated, and the light strip is easy be damaged. The main damages caused by voltage are:

　　1. Sudden increase in supply voltage

　　2. A certain LED strip is short-circuited due to some reasons, and its original voltage is transferred to other LED strips

　　Fourth, temperature and environment

　　1. LED is not very high temperature resistant, so if the welding temperature and welding time of the LED during the production process are not well controlled, the performance of the LED strip will be damaged due to the high temperature.

　　2. The LED needs to be dehumidified before use, otherwise the moisture in the LED package will expand during use due to moisture absorption in the early stage, which will indirectly cause the LED chip to overheat and damage

　　3. If the LED is used in an unsuitable environment, the waterproof level of the lamp is not enough. If water enters the lamp, the LED strip will also be damaged.

　　Five, static electricity

　　LED is an electrostatic sensitive component, so special attention should be paid to the problem of electrostatic protection during the production process, otherwise it is very likely that the LED chip will be burnt due to static electricity. In addition, anti-static work must be done when installing it.

　　6. Damage to the LED power supply and drive

　　Generally speaking, the damage to the LED power supply and driver comes from the over-voltage shock (EOS) of the input power supply and the open circuit fault at the load end. First of all, the over-current impact of the input power supply is likely to cause damage to the drive chip in the drive circuit, and breakdown and damage to passive components such as capacitors. The short-circuit fault at the load end can easily cause over-current driving of the drive circuit, resulting in short-circuit damage to the drive circuit or overheating damage caused by the short-circuit fault.
