High Voltage LED, a revolutionary technology in the lighting industry, has gained significant attention in recent years. As a type of LED, it operates at higher voltages compared to traditional LEDs, offering numerous advantages in terms of efficiency, brightness, and lifespan. This article aims to provide an in-depth introduction to the high voltage LED industry, covering its working principle, applications, market trends, and future prospects.
Working Principle of High Voltage LED
High Voltage LED, also known as High Voltage Light Emitting Diode, is a semiconductor device that emits light when an electric current passes through it. The key difference between high voltage LED and traditional LED lies in the voltage at which they operate. While traditional LEDs typically operate at voltages ranging from 3V to 3.5V, high voltage LEDs can operate at voltages as high as 24V or even higher.
The working principle of high voltage LED is based on the P-N junction. When a forward voltage is applied across the P-N junction, electrons and holes are injected into the junction, recombining and releasing energy in the form of light. The higher the voltage, the more electrons and holes are injected, resulting in higher brightness.
Advantages of High Voltage LED
Compared to traditional LEDs, high voltage LED has several advantages:
1. Higher Efficiency: High voltage LED can achieve higher efficiency due to the lower forward voltage requirement. This means that less electrical energy is wasted as heat, resulting in lower power consumption.
2. Higher Brightness: The higher voltage allows for a higher injection current, which in turn increases the brightness of the LED.
3. Longer Lifespan: High voltage LED has a longer lifespan due to the lower thermal stress caused by the lower forward voltage. This means that high voltage LED can be used in applications requiring long-term operation.
4. Lower Cost: High voltage LED can be produced at a lower cost due to the simpler manufacturing process and lower material requirements.
