What are the common causes of damage to LED lamps under normal conditions?
Because of its energy saving, environmental protection, long life and other characteristics, the market demand is increasing. However, people often use improper use of LED lamps in their daily lives and cause LED lamps to no longer have "longevity", so it is common to cause damage to LED projectors. What are the reasons? Fortune Lighting’s 20-year-old LED project-light lamp manufacturer will tell you the main reasons for the damage of LED lamps:
1. The power supply voltage rises suddenly and surges increase.
2. The short circuit of a component or printed line or other wire in the circuit forms a local short circuit of the LED power supply path, which increases the voltage in this place, and the solder joints are soldered or loose.
3. Some LEDs are short-circuited due to their own quality damage, and their original voltage drop is transferred to other LEDs. The internal resistance of the LED changes, and the voltage across the LED is uneven.
4. The temperature inside the lamp is too high, which deteriorates the characteristics of the LED; the temperature inside the lamp rises too fast; the temperature is too high during soldering or immersion tin.
5. Water enters into the lamp, and the water is conductive. The hot air flow in the enclosed lamp accumulates to form water vapor or mist.
6. During the light source test, it is switched on and off quickly, and the inter-electrode charge discharge (that is, it fades out when it is off).
7. The erosion of the washing water and the ultrasonic nanowave when washing the plate.
8. Live operation; all fixtures and fixtures do anti-static work; keep the temperature and humidity of the environment.
The common reasons for the damage of the LED lamps caused by the above 8 points are organized by the problems encountered by the Benwei lighting engineers in the actual work. I hope it will be helpful to everyone. Benwei Lighting has been focusing on LED indoor lighting fixtures for 12 years. It is an indoor lighting fixture manufacturer and service provider integrating production, R&D, sales and service.
