How much voltage can the LED lamp withstand?
What is the voltage of the ED lamp in general? We Guanghong LED lamp electronic production with conventional voltage specification is 12V and 24V, LED 12V lamp with LED lamp is three LED for a group of 24V band is 6 LED as a group. Customers have been asked to lower the power supply voltage, but not all colors, all specifications of the LED band can be used to reduce voltage, and it can not be unconditionally reduced. To make a clearer distinction between what specifications of LED lights, the band voltage can be reduced, and first look at the 5 conventional colors of a single LED drive voltage:1, white LED:3.0~3.3V2, red LED:1.8~2.2V3, blue LED:3.0~3.2V4, green LED:2.9~3.1V5 yellow LED:1.8~2.0VThe market standard DC power supply voltage specifications are 6V, 9V, 12V, 18V, 24V and so on, then LED lights with step-down specifications must also be consistent with these specifications, otherwise the power supply matching is also a problem.
LED lamp needs constant current driver, single wick turn-on voltage from 2.8V to 3V, and work for a period of time after the temperature rise, the value will be reduced, the lamp is a lamp wick composed of series parallel, because the number of different series, so the voltage is different, when the current basic variable voltage variable.
