Introduction to IR COB LED Technology

What is an IR COB LED?

The term "IR COB LED" stands for Infrared Chip-On-Board Light Emitting Diode. It is a type of LED that emits infrared light, which is a part of the electromagnetic spectrum that is not visible to the human eye. IR COB LEDs are widely used in various applications, including automotive, medical, industrial, and consumer electronics, where invisible light is required for communication, sensing, or illumination purposes. In an IR COB LED, the LED chips are mounted directly onto a substrate, eliminating the need for a traditional packaging process. This direct mounting allows for a more efficient and compact design, which is particularly beneficial for applications where space is limited. The absence of packaging also reduces the thermal resistance, enabling better heat dissipation and longer lifespan of the LED.

How Does an IR COB LED Work?

An IR COB LED operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. In the case of an IR COB LED, the semiconductor material is specifically chosen to emit infrared light. When an electric current is applied to the LED, electrons and holes are excited and recombine within the semiconductor. This recombination process releases energy in the form of photons, which are emitted as infrared light. The color and intensity of the light emitted depend on the composition of the semiconductor material and the current applied. The direct mounting of the LED chips onto the substrate in a COB (Chip-On-Board) configuration allows for a more efficient light output and better heat dissipation. The compact design also reduces the light loss due to reflections and scattering, resulting in higher overall efficiency.
