Technology

The 3mm infrared LED is a semiconductor device that emits infrared light when an electric current is applied. The device consists of a p-n junction, where the p-type material is doped with acceptor atoms, and the n-type material is doped with donor atoms. When an electric current is applied, electrons from the n-type material recombine with holes from the p-type material, releasing energy in the form of infrared light. The key factors that determine the performance of an infrared LED include its wavelength, intensity, and efficiency. The 3mm infrared LED typically emits light at a wavelength of 940 nm, which is within the near-infrared range. The intensity of the emitted light depends on the material quality, device design, and manufacturing process. Efficiency, on the other hand, refers to the ratio of the electrical power input to the light power output.
