The Characteristics and Application of Infrared LED Lamp Beads

Infrared LED lamp beads have been widely used in color TV, audio systems and various household appliances. The control distance of the remote control can generally reach 6 to 8 meters, and the use of a very lunch. Due to the large amount of infrared remote control measures, there are no lack of supporting devices in infrared launch and receiving circuit. These devices are not only low and reliable. Electronic lixtants can use these devices to assemble remote controls of various purposes, which are not only used but can increase production preferences. The characteristics of infrared LED lamp beads are not visible infrared, and people's eyes are not detected. Commonly used infrared LED lamp beads, its shape is similar to ordinary LED lamp beads. Decreasing pulse occupation ratio can also great. Common infrared light emitting diode, its power is divided into three categories: small power (1MW 10MW), medium power (20MW 50MW), and high power (50mW 100MW). When using different power infrared light -emitting diodes, the driver of the corresponding power should be equipped. To make the infrared light -emitting diode, just add a pulse voltage with a certain frequency to the drive pipe. When the infrared glow diodes are transmitted to control the controlled equipment, there are corresponding infrared photoelectric modification elements in the controlled equipment, such as infrared receiving diode, photoelectric triability, etc. There are two methods for infrared launch and receiving. Direct refers to the relative placement of the optical pipe and the receiving tube at both ends of the launch and the controlled matter, and the distance between the center must be distance; When you encounter a reflex, the receiving tube receives the infrared talent of the reflection.
