Working Principle of LN48YCP LEDs

The working principle of the LN48YCP LED series is based on the emitting of visible light when a voltage is applied between the anode and cathode terminals. The LED consists of a semiconductor chip that contains two regions of oppositely doped material. When an electrical current is passed through the LED, the electrons from the n-type material and the holes from the p-type material recombine and generate photons. These photons excite the electrons in the LED and give off visible light. The color of the light depends on the type of semiconductor material used in the LED and the wavelength of the light is determined by the materials used to make the LED.

Conclusion

The LN48YCP series of LEDs from KingBright is ideal for a wide range of applications, providing a compact, surface mountable LED with the choice of red, green and yellow colors. The excellent light output to space ratio and bright diffused colors make these LEDs ideal for discrete indication applications.
