(1) Low-power in-line LED lamp beads

Generally, they are divided into models by diameter, 3mm 4mm 5mm 8mm 10mm 12mm

Regardless of the diameter, its working voltage and working current are the same

Color: red light yellow light 1.7--2.1V

White light Blue light Warm white light Pink light Purple light 2.8--3.6V

Green light 2.6--3.4V

(2) LED lamp beads have a variety of specifications

1. 0.06W, the voltage is 2.5-3.5V, and the current is 20mA.

2. 0.5W, the voltage is 2.5-3.77V, and the current is 150mA.

3. For 1W, the voltage is 2.79-3.99V, and the current is 350mA.

4. For 3W, the voltage is 3.05-4.47V, and the current is 700mA.

5. For 5W, the voltage is 3.16-4.88V, and the current is 1000mA.

The current of the lamp bead 1W: 320-350mA, the selected driver is generally 300mA current, and the chip size is 30mil, 35mil, 40mil, 45mil.

The current of the lamp bead 3W: 700mA, the driver is generally 600mA, and the chip size is 45mil.

1W 3W voltage is between 3.0-3.6V, better 3.2-3.4V.

Generally, the LED lamp beads used for lighting are from 0.5w-5w, and the working voltage is about 3-3.2V.
