How many volts does a 20 cm LED light band take to bring it up?
Generally there is a transformer, you can buy directly with the power of the LED light belt ah! Generally 1 meters long, divided into two kinds of hard and soft!
Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on. 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.
A 20 cm LED light band needs 10v-20v voltage to take it up. The voltage required for the LED lamp is not significantly related to the size but is only related to the number of leds. The voltage required for a typical LED lamp is about 10v-20v.
