Introduction to Infrared COB LED

What is Infrared COB LED?

The infrared COB LED, short for Chip on Board infrared LED, is a type of LED that combines the advantages of traditional LED technology and the latest advancements in semiconductor technology. It is widely used in various fields such as automotive, medical, industrial, and consumer electronics. Infrared COB LED has a compact structure, high brightness, and excellent heat dissipation performance, making it an ideal choice for applications requiring high light output and stable performance.

Structure and Working Principle of Infrared COB LED

The structure of an infrared COB LED is similar to that of a traditional LED, but with some differences. It consists of a semiconductor chip, a phosphor layer, and a metal encapsulation. The semiconductor chip is the core part of the LED, which emits light through the phosphor layer after being excited by electricity. The phosphor layer is used to convert the emitted light into infrared light, and the metal encapsulation is used to protect the internal components and improve the heat dissipation performance. The working principle of an infrared COB LED is as follows: when the LED is powered on, the current passes through the semiconductor chip, causing the electrons and holes to recombine. During the recombination process, a large amount of energy is released in the form of light. The phosphor layer absorbs this light and converts it into infrared light, which is then emitted from the surface of the LED.
