History of Power LED Diodes

Power LED diodes have a rich history that dates back to the early 20th century. The first LED was invented by Oleg Vladimirovich Losev in 1927, but it was not until the 1960s that LED technology began to gain attention. In 1962, Nick Holonyak Jr. developed the first red LED at General Electric, marking a significant milestone in the development of LED technology. Since then, LED technology has evolved rapidly, and power LED diodes have become a vital component in various industries.

Technology of Power LED Diodes

Power LED diodes are made of semiconductor materials, such as gallium nitride (GaN), silicon carbide (SiC), and aluminum gallium indium phosphide (AlGaInP). These materials emit light when an electric current passes through them. The key factors that determine the performance of power LED diodes include the semiconductor material, chip size, and thermal management.

1. Semiconductor Material: Different semiconductor materials have different properties, such as emission wavelength, forward voltage, and luminous efficiency. For example, GaN-based power LED diodes offer high luminous efficiency and can emit light in a wide range of wavelengths, from blue to white.

2. Chip Size: The size of the LED chip directly affects the luminous intensity and heat dissipation of the power LED diode. Larger chips generally have higher luminous intensity but may require better thermal management.

3. Thermal Management: Power LED diodes generate heat during operation, and efficient thermal management is crucial for their performance and lifespan. Heat sinks, heat spreaders, and thermal interfaces are commonly used to dissipate heat from the LED chip.
