LED Power Supply works as AC adapter for laptop
LED drivere (også kendt som LED strømforsyninger) ligner ballaster til lysstofrør eller transformere til lavspænding pærer: de giver LED'er med den korrekte strømforsyning for at fungere og yde deres bedste. Ligesom Laptops brug AC-adapter, fluorescerende efterspørgsel ballast, LED-lys & skærme kræver egnet strømforsyning samt. Hvad er en LED driver? LED driver er kendt som LED-strømforsyning, som er den strømkilde til en LED-system. Denne vejledning af LED drivere vil dække konstant spænding eller konstant strøm LED-driver, dæmpning teknologi til førte strømforsyning, kvalitet, kontrol af LED driver, og etc. Artiklen fokuserer på LED-industrien. 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. Dog, low voltage LED light sources, such as some MR- pærer (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 (12-24Den), direct current electricity. Dog, most places supply high AC voltage (120-277Den), 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.
