Garden light LED light source low power high brightness

Shanghai College Restaurant Garden Light Project The garden lights use LED light sources, which can achieve the effect of low power and high brightness, save energy and illuminate the world. The VF voltage of LED light sources for lighting is very low, generally 2.75~3.8V, and IF is generally 15~1,400mA. Therefore, the output voltage of the LED driver IC is VFxN or VFx1, and the IF is kept constant at 15~1,400mA. There are two types of LED light sources used in LED lamps: low power (IF is 15~20mA) and high power (IF is greater than 200mA). Low-power LEDs are mostly used to make LED fluorescent lamps, decorative lamps, and grille lamps. High-power LEDs are used for home lighting, spotlights, underwater lights, wall washers, street lights, tunnel lights, automotive work lights, etc. The power LED light source is a low-voltage, high-current driven device, and its luminous intensity is determined by the current flowing through the LED. Too much current will cause LED light attenuation, and too small current will affect the luminous intensity of LED. Therefore, the driving of the LED needs to provide a constant current power supply to ensure the safety of high-power LED use and achieve the ideal luminous intensity at the same time. In the field of LED lighting, in order to reflect the energy-saving and long-life characteristics of LED lamps, the correct selection of LED driver ICs is crucial. Without the matching of a good driver IC, the advantages of LED lighting cannot be reflected. Company: Shanghai CHZ Changhui Lighting Technology Co., Ltd. Website: www.chz-lighting.com
