What is the voltage and current of the 9 head LED flashlight?
The nominal voltage of single white light LED is 3.2V, 20mAHow much is your flashlight battery voltageIf the 1.2V rechargeable battery is used, the booster circuit must be used, and a simple step-up circuit is shownThe two circuit for single cell white light LED I do with the pack must be bright, basically do not debuggingUse three LED strings
When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.
The nominal voltage of single white light LED is 3.2V, 20mA.
