3mm multi-color LED is a type of light-emitting diode (LED) with a diameter of 3mm. It is widely used in various industries due to its small size, high brightness, and multiple color options. This article aims to provide an in-depth introduction to the 3mm multi-color LED industry, covering its history, technology, applications, and market trends.

History of 3mm Multi-Color LED

The invention of the LED dates back to the 1960s, and since then, it has undergone significant development. The 3mm multi-color LED was first developed in the late 1980s. At that time, due to the limitations of technology, the color gamut of the 3mm multi-color LED was relatively limited. However, with the continuous advancement of technology, the color gamut and brightness of the 3mm multi-color LED have been greatly improved, making it widely used in various fields.

Technology of 3mm Multi-Color LED

The 3mm multi-color LED is based on the principle of light-emitting diode. It consists of a semiconductor chip, a lens, and a lead frame. The semiconductor chip is the core part of the LED, which can emit light through the lens after being energized. The color of the light emitted by the LED is determined by the material of the semiconductor chip. The 3mm multi-color LED can be divided into two types: RGB and RGBW. The RGB LED emits red, green, and blue light, and can be mixed to produce various colors. The RGBW LED adds a white light channel, which can improve the brightness and color purity of the LED.
