5mm LED multi-color has become an essential component in the lighting industry, offering a wide range of applications and benefits. This article aims to provide an in-depth introduction to the 5mm LED multi-color market, covering its history, technology, applications, and future trends.

History of 5mm LED Multi-Color

The concept of multi-color LED technology dates back to the early 1990s when scientists and engineers began to explore the possibility of combining different colors in a single LED device. The first multi-color LEDs were produced using a technique called phosphor mixing, which involved coating the LED with a thin layer of phosphor material that could emit light of a specific color when excited by the LED's light. In the 2000s, the development of chip-on-board (COB) technology allowed for the integration of multiple colors in a single LED package, making 5mm LED multi-colors more compact and efficient.

Technology of 5mm LED Multi-Color

The 5mm LED multi-color technology is based on the principle of color mixing, which involves combining red, green, and blue (RGB) light to produce a wide range of colors. The RGB LEDs are typically mounted on a single die, and the color mixing is achieved by adjusting the intensity of each color. The following are some key aspects of the technology: 1. Chip-on-Board (COB) Technology: COB technology allows for the integration of multiple LEDs on a single die, reducing the size and improving the efficiency of the LED package. 2.
