Infrared diode is a diode that can emit infrared, which is usually used in remote controls and other occasions. The commonly used infrared light -emitting diode is similar to the LED LED of the emitting diode, emitting infrared light. The pipe pressure drops by 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. What are the shapes of infrared light emitting diode?

In some color TV infrared remote controls, the working pulse ratio of infrared light pipes is about 1/3-1/4; some electrical products infrared remote controls, the duty ratio is 1/10. Decreasing pulse occupation ratio can also greatly increase the launch distance of small -power infrared light -emitting diodes. For 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 or more). To make the infrared light -emitting diode generated, the pulse voltage of a certain frequency is added to the driver.
