Infrared LED lamp bead applications and characteristic Infrared LED lamp beads are 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, which is very convenient to use. Due to the large amount of infrared remote control measures, its infrared launch and acceptance circuits have no lack of supporting equipment. These equipment is not only low and reliable, but the circuit is very simple. Electronic lixtants can use these equipment to assemble remote controls of various uses, not only use and can be added to make preferences. The characteristics of infrared LED lamp beads are not visible, and human eyes are not found. Commonly used infrared LED lamp beads, the shape is similar to the average LED lamp bead. Decreasing pulse occupation ratio can also greatly add the launch distance of small -power infrared light -emitting diode. 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 glow diodes, the lighting of light, just add a certain frequency pulse voltage to the driving pipe. When the infrared glow diodes are transmitted to control the controlled device, there are corresponding infrared photoelectric conversion elements in the controlled equipment, such as infrared accepted diodes, photoelectric triabilities, etc. There are two ways of infrared launch and acceptance. Direct refers to the relative placement of the optical pipe and the acceptance tube on the two ends of the launch and the controlled matter, and the distance between the center must be distance; the reflection of the light pipe and the acceptance tube are tied together. When encountering a reflex, accept the tube to receive the infrared line of the reflection. Glowing acceptance
