LED 4mm white has become a popular choice in the lighting industry due to its versatility and efficiency. This article aims to provide an in-depth introduction to the LED 4mm white market, covering its history, technology, applications, and future trends.

History of LED 4mm White

The LED (Light Emitting Diode) technology has been around for several decades, but it was not until the late 20th century that white LEDs started to gain attention. The first white LED was developed in 1993 by Shuji Nakamura, a Japanese scientist, who used a combination of gallium nitride (GaN) and indium gallium nitride (InGaN) to create a blue LED. By mixing blue light with phosphor, white light could be produced. The LED 4mm white was born, and it quickly became a favorite among consumers and businesses alike.

Technology of LED 4mm White

The LED 4mm white is a type of LED that emits white light with a diameter of 4mm. It is composed of a blue LED chip, a yellow phosphor layer, and a clear encapsulant. When the blue LED chip emits light, the yellow phosphor layer absorbs the blue light and emits yellow light. The combination of blue and yellow light creates white light. The color temperature of the LED 4mm white can be adjusted by changing the phosphor material and the ratio of blue and yellow light.
