Question:

The voltage of the LED lamp is about how much

The voltage of the LED lamp is about how much

Answer:

If you buy a product of lamps and lanterns, it should indicate the rated voltage. If it is homemade, you can choose according to the input voltage connection. You three series, 5 groups and then together, you can pick up in 10 v
Power are using domestic load voltage 220 v, after ac into dc, again after decompression for the LED power supply, how many v voltage, LED need according to the design to have different version for different voltage, such as there are 5 v, 6 v, 9 v, 12 v, 16 v, 24 v, 32 v, etc. A LED light-emitting diode connection: string increase the voltage, electric current is constant. And even the constant voltage, electric current increase. For reference only.
Like to see the instruction manual. General desk lamp is 6 v or 12 v (lead-acid battery). 3.6 V or 7.2 V (lithium ion battery). 220 plug into mains, after a step-down rectifier transform into direct current, lit LED lights, and recharge the battery (losing electricity state). The working voltage of a single LED lamp is between 3.2 3.6 V, usually series after parallel. If you don't know how much is the voltage, disassemble the lamps and lanterns, count you know leds in series voltage
No, now the best solution is a string of ten. And then in parallel. Voltage is controlled in 32 v, with constant current source driver. Safety, high efficiency
