Infrared LED Lamp Beads of Various LED Lamp Bead Specifications of Various LED Lamp Beads

Conventional infrared LED lamp beads and general visible light LED lamp beads are similar, but they are infrared. Its voltage is generally 1.4V, and the current of the matter is generally less than 20mA. In order to adapt to the difference between the difference, the limited flow resistance in the circuit often serves. When using the infrared LED lamp beads to control the corresponding controlling device, its control distance is proportional to the launch power. In order to increase the restraint distance of infrared rays, infrared launch supervisors work in the pulse state, because the useful transmission distance of the pulse light is directly proportional to the veins of the pulse, and only need to try to mention the IP of the Cenling value. The essentials to improve the IP are the duty -to -duty duty cycle, that is, the width T of the compressed pulse, the reduction of the duty -to -duty duty cycle can also make the launch of the low -power infrared light. Ordinary infrared light emitting diode, its power is divided into small power, medium power, and three -year night category. To make the infrared light emitting diode generate, the pulse voltage that only needs to add the inevitable frequency on the drive tube. When infrared diode emitted infrared rays to control the controlled device, there are corresponding infrared photoelectric conversion elements in the control device, such as infrared absorption dilateral, infrared suction head, light -sensitive triode, etc. There are two types of infrared launch and absorption. Direct refers to the optical pipe and the absorption tube relative to the two ends of the launch and the controlled matter, and the distance between the middle is bound to be separated; When the light encounters a reflex, the absorption tube receives the infrared light of the reflection. Double -tube infrared launch circuit can improve the launch power and increase the distance of the infrared launch. According to the characteristics of infrared LED lamp beads, a wider range of applications can be obtained according to the differential wavelength: first, wavelength: 808nmled lamp bead standard, suitable for medical utensils, space light communication, infrared lighting, solid laser pump light sources; 2. Wavelength length : 830nm, the automatic card system suitable for high -speed roads (the night vision system is the best, you can see that there is a little red light on the tube core, the effect is better than 850nm); three, wavelength: 840nm, suitable for cameras and color change infrared waterproof Fourth, wavelength: 850nm, suitable for cameras, digital photography, monitoring, Louyu intercom, anti -theft alarm, infrared waterproof; 5. 870nm, suitable for cameras at shopping malls and crossroads; Remote control, such as the remote control of home appliances. --- The article comes from LED lamp beads, please indicate Tongjia (China) www.tongjialed.com
