The importance of the led flat panel lighting power supply

    Popular in the LED panel lights at the same time, an important component of its -- drive power has been paid attention to. Because the drive power quality LED panel lamp directly determines the reliability of the LED panel light, so with the development of LED panel light industry, LED driving power supply is gradually mature. Here we introduce you the importance of the led flat panel lighting power supply.
    Since LED is a sensitive semiconductor device, but also has a negative temperature characteristic, therefore in the application process need to be stabilized and protected the, resulting in a concept of drive.
    LED requirements for driving power supply is very strict, LED panel light can not be directly connected to the AC mains. LED is 2 to 3 volt low driving voltage, need to transform a complex circuit design, LED lamps with different purposes, to be equipped with the power adapter of different.
    The international market of foreign clients on the LED panel lamp driver power conversion efficiency, effective power, the precision of constant current, power life, electromagnetic compatibility requirements are very high, the design of a good power supply must be comprehensive consideration of these factors, because the led lighting panel power supply are as important as the human heart.
    First is the driving circuit of whole life, especially the key components, such as capacitors under high temperature service life directly affects the life of the power supply. Second is the LED driver should be converted to challenge higher efficiency, especially in the high-power LED drive, because the output of the power there is a part of dissipated as heat, power conversion efficiency is too low, affected the play LED panel light energy-saving effect.
