LED 4mm white has become an indispensable component 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 history of LED 4mm white can be traced back to the early 2000s when LED technology began to gain traction in the lighting industry. Initially, LED 4mm white was primarily used in indicator lights and small display panels. However, with the advancement of LED technology and the increasing demand for energy-efficient lighting solutions, the applications of LED 4mm white expanded rapidly.

Technology of LED 4mm White

LED 4mm white is a type of light-emitting diode (LED) with a diameter of 4mm. The color of the LED is determined by the material used in its semiconductor chip. In the case of LED 4mm white, the semiconductor material is typically a combination of gallium nitride (GaN) and indium gallium nitride (InGaN). These materials emit light at a wavelength of around 470nm, which corresponds to the white color spectrum. The manufacturing process of LED 4mm white involves several steps. First, the semiconductor material is deposited on a substrate, usually a silicon or sapphire wafer. Then, a series of layers, including the active layer, are deposited on top of the substrate using a process called epitaxy. Finally, the LED is encapsulated in a clear, transparent material to protect the semiconductor chip and enhance its light output.
