Introducing the Infrared COB LED: A Revolution in Lighting Technology

Introduction to Infrared COB LED

The infrared COB LED, short for Chip on Board infrared light-emitting diode, represents a significant advancement in the field of lighting technology. Unlike traditional LED packages, which are often surface-mounted, the COB LED integrates the entire chip onto a single board, resulting in a more compact and efficient lighting solution. This technology has gained popularity in various applications, including automotive, medical, and industrial sectors, due to its superior performance and versatility.

How Infrared COB LED Works

The infrared COB LED operates on the principle of light emission from a semiconductor material. When an electric current is applied to the diode, it excites the electrons within the semiconductor, causing them to recombine and release energy in the form of light. In the case of infrared COB LEDs, the emitted light falls within the infrared spectrum, which is not visible to the human eye but can be detected by various sensors and devices. The key components of an infrared COB LED include the semiconductor material, which is typically made of gallium arsenide (GaAs) or gallium nitride (GaN), the chip, and the substrate. The chip is the heart of the LED, where the light is generated. The substrate provides structural support and thermal management to the chip. By integrating the chip onto a single board, the infrared COB LED achieves higher efficiency and better heat dissipation compared to traditional LED packages.

Advantages of Infrared COB LED

There are several advantages that make the infrared COB LED a preferred choice in various applications: 1.
