Infrared emission tube is a kind of expressible luminous body material composed of infrared light-emitting diodes used after a series of operations. When this product is produced, it needs to use existing materials with high infrared radiation efficiency, such as gallium arsenide, which is commonly used. Then we use this to make a PN junction, where the forward bias will inject current into the PN junction to excite infrared light. After we do this, the approximate spectral power of the infrared light that can be excited is generally distributed in the center wavelength of 830~950nm.

In the process of use, we need to know that the performance of light-emitting diodes is displayed by a specific coefficient of positive temperature. The greater the current here, the higher the temperature will naturally become, and the higher the temperature, the greater the current will be. . At the same time, the power of the LED infrared diode here has a lot to do with the specific current we give it. But at the same time we also need to pay attention to that, once the forward input current exceeds its original maximum rating, the infrared diode's transmit power will start to drop rapidly instead.

　　 In fact, the infrared emitting tube we know is also called infrared emitting diode, which is also a type of light emitting diode. This kind of emitting diode is generally used in the emission light source used for daily control of various instruments. Generally speaking, the radiation angle of this type of emitting diode in the use of different packaging process models will vary according to the situation in which it is used. For example, in our common monitors, there is this kind of technology in it, so that it can better capture the objects within the scope of the monitor.
