The VF voltage of LED light sources for lighting is very low, generally 2.75~3.8V, and IF is generally 15~ 1,400 mA. Therefore, the output voltage of the LED drive IC is VFxN or VFx1, IF the constant current is maintained at 15~ 1,400 mA. There are two kinds of LED light sources for LED lamps: small power (IF 15~20mA) and large power (IF greater than 200mA). Small power LED is used for making LED fluorescent lamps, decorative lights, grille lights. High-power LED is used to do household lights, spotlights, underwater lights, wall washing lights, street lamps, tunnel lights, car work lights, etc. The power LED light source is a device driven by low voltage and high current. Its luminous intensity is determined by the current flowing through the LED. Excessive current will cause LED light attenuation, and too small current will affect LED light intensity. Therefore, the DRIVE of LED needs to provide a constant current power supply, so as to ensure the safety of high-power LED and achieve the ideal luminous intensity. In the field of LED lighting, in order to reflect the characteristics of LED lamp energy and long life, the right choice of LED drive IC is very important. Without a good driver IC match, the advantages of LED lighting cannot be reflected.
