life of LED drive
Using long life capacitors does not guarantee that the power life, to improve the power life, you need ways to improve: use the higher life expectancy of capacitor, improve power efficiency, the thermal design power, thermal design of optimized lamps. Many lamps and compact in order to reduce the weight of the enterprises in order to take into account lighting design, require compact volume and install a power supply in a confined space, their thermal conditions of the power supply is limited. High efficiency, small volume and better thermal design power LED challenges.
Apart from some traditional lamps power converts sunlight outside, most of the power is converted into infrared radiation energy radiation to the lamps and lanterns outside space, LED lighting is different. LED is a semiconductor light-emitting, outside its some of its power conversion of light energy, most of the power is converted to heat, the heat can only be use in close connection with the lamp cooling
To make the lighting product be beautiful, LED and power LED lights with compact design, LED of heat and power heating superimposed, such power and the LED lights are in the poor working environment, when the work environment temperature exceeds a certain temperature, the LED power and LED life greatly diminished. Set temperature inside of the power supply protection occurs when you repeatedly switch lights, set temperature protection will not cause high temperatures can damage the power supply devices and accelerate lumen LED.
LED power belongs to the switching power supply, switching power supply's quality and reliability depends on its circuit design, production processes, and quality of the device. Electrolytic capacitors are essential components of the high power switching power supply.
Switching power supply using normal working life depends on the power of life of electrolytic capacitors, electrolytic capacitor capacitance of the life expectancy depends on their own life and operating temperatures.
