How to distinguish infrared emission tube model specifications

Infrared emitter tube model too much, there is a direct plug and patch type, and high power infrared emitter tube, infrared emitter tube current from dozens of milliamps to a few amps have, the voltage is relatively consistent, most are a few volts at three points, no way to generalize.Roughly speaking, according to the package is directly inserted, patch.According to power, it is divided into large, medium and small power.

High-power white light (such as CREE xml-t6) has reached 10W per power, voltage 3.3v current 3A, low-power red light (such as common 5MM direct insertion) voltage 2v, current 15 ma.If no element model can be found, the working voltage can be inferred according to the light color:

Red light from 1.8 v to 2.2 v

Yellow light from 2.0 v to 2.4 v

The green light from 2.2 v to 2.8 v

Blue and white light 2.8~3.5v

The patch package is 0805, 1206 and other small power tube, and the working current is usually 10 ma, but there are exceptions.

The SMD package is 3014, 3528, 3535 and other small power tubes. The working current is usually 20 to 50 ma, but there are exceptions.

The SMD package is 5050, 5060, 5630 and other medium power tubes. The working current is usually 50~150 ma, but there are exceptions.

High power is all SMT packaging, different brands of different series of parameters are very different;However, the normal operating current of 1W is 350mA

Small power direct-inserted infrared emission tube, usually according to the diameter of the model,

3 mm4mm5mm8mm10mm12mm.The working voltage and working current are the same regardless of the diameter.

Color: red and yellow 1.7-- 2.1v

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

Green light 2.6-3.4 V

Infrared emitter tube has a variety of specifications:

1.0.06w, voltage is 2.5-3.5v, current is 20mA.

For 2.0.5w, the voltage is 2.5-3.77v and the current is 150mA.

3.1w, voltage 2.79- 3.99v, current 350mA.

4.3w, voltage 3.05- 4.47v, current 700mA.

5.5w, voltage 3.16-4.88v, current 1000mA.

The current of 1W infrared transmitter tube: 320-350ma, the driver is usually selected 300mA current, chip size 30mil, 35mil, 40mil, 45mil;

Infrared transmitter tube 3W current: 700mA, drive usually 600mA, chip size 45mil;

1W3W voltage is between 3.0-3.6v, better 3.2-3.4v;

As for the specific parameters of a single 5W chip, I am not clear. The chip is usually above 50mil.Infrared emission tubes, which are usually used for lighting, range from 0.5w to 5w;

The working voltage is about 3-3.2v.

What are the parameters of white light 1-watt infrared emitter tube? We usually design 3.6-- 4.2V, 0.2-- 0.3A.

You can refer to it.Such as creemce creet6.

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

Methods to distinguish infrared emitter tube:

1. See the brightness, that is, the brightness at the driving current of 350mA and the voltage between 3.0v and 3.6v, the higher the better.

2. Look at chip brands and sizes. Brands include NICHIA, CREE, prui, xuming, wafer and new century.

3. See the division BIN, namely, color temperature division and voltage division BIN, the finer the better.

4. To see the attenuation, aging test is needed. The smaller the light decay, the better.

5. For practical applications, such as: the market has a suitable and cheap lens, aluminum substrate, it is good, lens, aluminum substrate need to open the mold, will invest a little more, 1W high power, current: 350ma, voltage: 2.8-4.0v brightness: 80-130lm color temperature: 3000%-12000k.
