With the rapid development of technology, invisible infrared LED has emerged as a revolutionary product in the field of lighting. As the name suggests, these LEDs emit infrared light that is invisible to the naked eye, making them ideal for various applications that require covert illumination. This article aims to provide an in-depth introduction to invisible infrared LED, covering its technology, applications, advantages, and market trends.

Introduction to Invisible Infrared LED

Invisible infrared LED, also known as invisible infrared diode, is a type of light-emitting diode that emits infrared light with a wavelength outside the visible spectrum. The invisible infrared LED emits light in the near-infrared region, which is between 780 nm and 1400 nm. This type of LED is designed to be unnoticeable to the human eye, making it an excellent choice for applications that require discreet illumination.

Technology of Invisible Infrared LED

The technology behind invisible infrared LED is based on the principles of photonic crystal and quantum dot. Photonic crystal is a type of periodic structure that can control the propagation of light waves, while quantum dot is a tiny semiconductor particle with unique optical properties. By combining these two technologies, manufacturers can produce invisible infrared LEDs with high efficiency and excellent performance. In the production process, the photonic crystal structure is integrated into the LED chip to guide the light waves and enhance the extraction efficiency. Quantum dots are then used to adjust the emission wavelength of the infrared light, making it invisible to the human eye. This technology allows invisible infrared LEDs to achieve high luminous efficiency, long lifespan, and stable performance.
