We all know that no matter what product has its shelf life, of course, LED power is no exception. Shenzhen Lianyunda Xiaobian believes that the impact of LED power supply life, the following aspects.
1. The internal temperature of the lighting, the temperature of the lighting enclosure and the temperature of the adapter will affect the service life of the LED power supply.
2, in the strong magnetic, dusty, high humidity, high temperature, vibration environment will have a certain impact on the life of the LED power supply.
3. The voltage input of the unstable power grid will impact the components of the adapter, thus affecting the service life of the LED driver.
4, the correct installation of the product and good insulation will enhance the application of the adapter.
5. The sealed part of the electrolytic capacitor will leak out the vaporized electrolyte. This phenomenon will accelerate with the increase of temperature. The electrolytic capacitor determines the life of the LED power adapter.
6. Most adapters have a capacitor input type rectification circuit. When the adapter is connected, a surge current will be generated, resulting in fatigue of the switch contacts, causing problems such as increased contact resistance and adsorption.
7. In order to offset the inrush current generated when the adapter is connected, the adapter is usually designed to use resistors in parallel with components such as SCR. The peak value of the power when the adapter is turned on is up to several tens to hundreds of times the rated value, resulting in thermal fatigue of the resistor, causing an open circuit.
