High voltage LED, also known as high voltage light-emitting diode, is a type of LED with a higher forward voltage than traditional LEDs. This article will introduce the high voltage LED industry, including its definition, working principle, application fields, advantages, challenges, and future development trends.
Definition and Working Principle of High Voltage LED
High voltage LED refers to an LED with a forward voltage higher than 5V. The working principle of high voltage LED is similar to that of traditional LEDs. When a forward voltage is applied to the LED, electrons and holes are injected into the PN junction, and recombination occurs in the active layer. The energy released during recombination is converted into light energy, thereby emitting light.
