High power LED white is a cutting-edge technology that has revolutionized the lighting industry. With its high efficiency, long lifespan, and versatility, it has become a popular choice for various applications. This article aims to provide an in-depth introduction to the high power LED white industry, covering its history, technology, applications, and future prospects.
History of High Power LED White
The concept of LED lighting dates back to the early 20th century when the first LED was invented. However, it was not until the 1990s that high power LED technology began to emerge. In 1993, Nichia Corporation, a Japanese company, successfully developed the first high brightness blue LED. This breakthrough paved the way for the development of white LED technology.
With the advancement of technology, the efficiency of high power LED white has significantly improved. In the early 2000s, the efficiency of high power LED white reached around 70lm/W. Today, the efficiency has increased to over 150lm/W, making it a highly competitive lighting solution.
Technology of High Power LED White
High power LED white technology is based on the principle of converting electrical energy into light. The key components of a high power LED white include a semiconductor chip, a phosphor coating, and a heat sink.
The semiconductor chip is the core component of the LED. It is made of a gallium nitride (GaN) material and emits light when an electric current passes through it. The phosphor coating is applied on the surface of the semiconductor chip to convert the emitted light into white light. The heat sink is used to dissipate the heat generated by the LED during operation, ensuring its long lifespan.
There are two main types of phosphor coating used in high power LED white technology: phosphor-converted LED (PCLED) and phosphor-converted chip-on-board (PCCOB). PCLED involves coating a phosphor on the surface of the semiconductor chip, while PCAOB involves directly bonding the phosphor to the semiconductor chip.
