What kind of LED lights are useful to power adapters? How many volts power adapters are used in general?
The adapter output voltage varies according to the type of the LED lamp. Usually between 3 volts and 80 volts. LED portable light, LED lamp holder and other power adapter output voltage is 5 volts, you can directly use mobile phone charger instead. LED, advertising lights, etc., need higher voltage, or even reach 80 volts.
Any use of alternating current as a power supply, all need to use the power adapter [directly on the 220 volt lamp holder on the LED light bulb, except because it comes with variable voltage rectifier circuit]. For example: neon lamp advertising box, LED desk lamp, LED flat lamp, decorative LED bead string, LED carry on lamp, head mounted LED lamp and so on. In addition, LED carry light, LED head lamp, LED portable lamp holder, etc., can be directly inserted in the voltage adapter [cell phone charger] use, can also be inserted in the use of charging treasure.
Where the use of alternating current LED lights have to use the power adapter, usually switching power input 220V, the output voltage according to the different combinations of LED lights and different forms, 12-80V have
LED lamps for general household lighting, the lighting brightness according to their needs, set up their own production and practice of power supply in series or can choose DC 3 12V can be, some need to reduce on the shunt resistance voltage or current size, protect the safety of LED. According to the brightness of the needs of their choice of voltage size on it.
