LED Power Supply works as AC adapter for laptop
drivers de LED (também conhecida como fontes de alimentação LED) são semelhantes aos balastros para lâmpadas fluorescentes ou transformadores para lâmpadas de baixa tensão: eles fornecem LEDs com a fonte de alimentação correta para funcionar e executar no seu melhor. Assim como Laptops precisa adaptador AC, lastro demanda fluorescente, Luzes LED & monitores necessitam de fonte de alimentação adequada, bem. O que é um LED driver? LED driver é conhecido como fonte de alimentação LED, que é a fonte de energia para um sistema de LED. Este guia de drivers de LED cobrirá tensão constante ou condutor de corrente constante levou, escurecimento tecnologia para fornecimento de energia levou, qualidade, controlo do controlador levou, e etc. O artigo está se concentrando na indústria de LED. Below, we discuss when you need an LED driver, why you need an LED driver, and what type of driver you may need.
The working voltage of LED light is DC, which means every LED light source requires a driver to transform the AC power to DC. Some LEDs already include an integrated driver within the bulb. LEDs designed for household use (global bulbs with E26 / E27 or GU24 / GU10 bases and that run on 240V or 120V) typically already include a driver. Contudo, low voltage LED light sources, such as some MR- lâmpadas (MR GU5.3s, MR8s, and MR11s) and tape light, as well as certain fixtures, panels, or outdoor-rated lights, usually require a separate driver. When an LED that requires a separate driver stops working before the end of its rated lifetime, it can usually be saved if the driver is replaced.
- LEDs are designed to run on low voltage (12-24O), direct current electricity. Contudo, most places supply high AC voltage (120-277O), alternating current electricity. An LED driver’s main purpose is to rectify higher voltage, alternating current to low voltage, direct current.
- LED drivers also protect LEDs from voltage or current fluctuations. A change in voltage could cause a change in the current being supplied to the LEDs. LED light output is proportional to its current supply, and LEDs are rated to operate within a certain current range (measured in amps). Too much or too little current can therefore cause light output to vary or degrade faster due to higher temperatures within the LED. In sum, LED drivers serve two purposes: to convert higher voltage, alternating current to low voltage, direct current, and to keep the voltage or current flowing through the circuit at its rated level.
