There are too many types of infrared emission tubes, there are direct insertion and patch type, as well as high-power lamp beads. The lamp current is from tens of milliamperes to several amps. The voltage is relatively consistent, mostly at three points. A few volts. There is no way to generalize.

Roughly speaking, according to the package, it is divided into direct insertion, patch, and LED piranha lamp bead. According to the power, it is divided into large, medium and small power.

High-power white LEDs (such as CREE's XML-T6) have a single power of 10W, a voltage of 3.3v and a current of 3A, and a low-power red LED (such as a common 5MM in-line) with a voltage of 2v and a current of 15mA.

If you can't find the component model, you can infer the working voltage according to the light color:

Red light 1.8~2.2v

Huang Guang 2.0~2.4v

Green light 2.2~2.8v

Blu-ray and white light 2.8~3.5v

The chip package is a small power tube such as 0805 and 1206, and the working current is generally 10 mA, but there are exceptions;

The chip package is a small power tube such as 3014, 3528, 3535, etc. The working current is generally 20~50 mA, but there are exceptions;

The chip package is 5050, 5060, 5630 and other medium power tubes, and the working current is generally 50~150 mA, but there are exceptions;

High-power LEDs are all packaged in SMD. The different series of different brands of different companies have very different parameters; but the nominal working current of 1W is 350mA.

Low power in-line infrared emission tube

Generally according to the diameter of the model, 3mm 4mm 5mm 8mm 10mm 12mm

Regardless of the diameter, its operating voltage and operating current are the same.

Color points: red light yellow light 1.7--2.1V

White light blue warm white light pink light purple light 2.8--3.6V

Green light 2.6--3.4V

Infrared launch tubes come in a variety of sizes

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

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

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

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

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

Lamp 1W current: 320-350mA, the selection drive is generally 300mA current, chip size 30mil, 35mil, 40mil, 45mil.

Lamp 3W current: 700mA, drive 600mA, chip size 45mil.

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

As for the single 5W company, we have not produced it yet, so I don't know the specific parameters. The chip is generally 50mil or more.

Generally used for illumination, the infrared emission tube is available from 0.5w to 5w, and the working voltage is about 3-3.2V.

What is the parameter of white LED 1W lamp bead? Our general design is 3.6---4.2V, 0.2---0.3A. There are still many 15W lamp beads.

Voltage: 3.2-3.6v, current 300-350ma, luminous flux: 100-120 lumens, color temperature: white light 6000-7000K.
