Why led lamp is damaged, why there are some way

1, the power supply voltage jump. Let the power supply have many reasons for sudden high voltage, such as zhongshan hundred DE photoelectric co. , LTD. Power quality problems, or the user's improper use, and so on reasons can let the power of the power supply voltage rise suddenly.

1。 Sudden high supply voltage. The power supply voltage rises abruptly, there are many reasons. Burt of photoelectric co. , LTD. , the power quality problems such as zhongshan, the user use undeserved, etc. The sudden rise could lead to a power supply voltage. 2. Some components or printed circuit and other circuit in circuit of short circuit formed led the local short circuit of power supply path, which has increased its voltage. 3. If a light emitting diode is damaged, due to its own quality lead to short circuit, the original voltage drops were transferred to other leds. 4. Temperature is too high in the lamp, make the article light-emitting diode characteristics of the brand. 5, lamps and lanterns in the water, water is conductive. 6. In the process of assembly, anti-static isn't doing a good job, cause the leds inside in light-emitting diodes, light box damaged by static electricity in the process of production in detail. Although using normal voltage and current value, light-emitting diodes (leds) are easily damaged. All of these reasons can lead to the development of light emitting diode current surging, light emitting diode chip will soon burnt due to overheating. According to our experience, most of the light emitting diode burned is poles short circuit, a few are open. Each light emitting diode voltage drop is about 3. 2 volts. If it is burnt out, if it is cut off, the string of leds will not shine. If the short circuit voltage, it will be transferred to other light-emitting diode, led to more current to other light-emitting diodes (leds), other leds would burn up faster, and even a threat to the power supply. If it is a small accident, it is easy to cause accident. Leds are normally installed in high, is not easy to install, more difficult to maintain. , therefore, the protection of light-emitting diodes (leds) is a kind of realistic demand, but at present, the definition of a light emitting diode bulbs, use, supply and purchase information, and industry information has not caused enough attention, this is also a lot of people have to face a problem.
