Introduction to High Power LED Chips

High power LED chips are a type of light-emitting diode (LED) that emit a higher intensity of light compared to traditional LEDs. These chips are designed to produce a higher lumen output, which is the measure of light emitted by a light source. The increased luminosity is achieved by using a larger semiconductor material and optimizing the design for better light extraction.

History of High Power LED Chips

The development of high power LED chips can be traced back to the early 2000s when manufacturers began to focus on increasing the brightness of LEDs. Initially, these chips were used in niche applications such as automotive lighting and architectural lighting. However, with advancements in technology and cost reductions, high power LED chips have become increasingly popular in consumer, commercial, and industrial lighting markets.
