The Characteristics and Applications of Infrared LED Lamp Bead Patch

The characteristics of infrared LED lamp beads are similar to the shape of the general visible light LED lamp beads, but the infrared rays are issued. Its voltage is generally about 1.4V, and the working current is generally less than 20mA. In order to adapt to different working voltage, limited flow resistance in the circuit. When using infrared LED lamp beads to control the corresponding controlling device, the distance between its control is proportional to the launch power. In order to increase the control distance of infrared rays, the infrared LED launch tube is working in the pulse state, because the effective transmission distance of the pulse light is proportional to the veins of the pulse. As long as you try to increase the peak IP, you can increase the transmission distance of infrared light. The method of improving IP is to reduce the pulse to the duty ratio, that is, the width T of the compressed pulse, the duty -duty duty cycle can also increase the launch distance of the low -power infrared light. Ordinary infrared light emitting diodes are divided into three categories: small power, medium power and high power. To make the infrared light emitting diode generate, just add a certain frequency pulse voltage to the drive tube. When infrared diode emitted infrared rays to control the controlled device, there are corresponding infrared conversion elements in the control device, such as infrared receiving diodes, infrared receiving heads, light -sensitive triode, etc. There are two ways to launch and receive infrared launch, namely direct and reflectives. Direct refers to the relative to the two ends of the launch and the controlled by the optical pipe and the receiving tube, and the middle phase is a certain distance in the middle; the reflection of the light pipe is tied together with the receiving tube. Usually the receiving tube is always no light, and only the infrared emitted by the luminous pipe only in the luminous pipes. When the light encounters a reflex, the receiving tube receives the infrared light returned from the reflection. Double -tube infrared launch circuit can increase the launch power and increase the distance of infrared launch. Specializing in the production of various types of LED lamp beads, we are all customized according to the needs of customer product needs, and according to the characteristics of infrared LED lamp beads, we can get a wider range of applications according to different wavelengths: 1. Wave length: 808nm, applicable to applicable In the pump light source of medical equipment, space light communication, infrared lighting, and solid laser; 2, wavelength: 830nm, suitable for automatic card swiping system on high -speed roads (the night vision system is best, you can see that there is a little red light on the tube core. , The effect is better than 850nm); 3, wavelength: 840nm, suitable for cameras and color change infrared waterproof; 4, wavelength: 850nm, suitable for cameras, digital photography, monitoring, building intercom, anti -theft alarm, infrared waterproof; 5 Wavelength: 870nm, suitable for cameras at the intersection of shopping malls and crossroads; 6. Palace: 940nm, suitable for remote control, such as the remote control of home appliances. Zhuhai Co., Ltd. is a professional LED lamp bead manufacturer with a number of national patents.
