Introduction to the 1608 Infrared LED Industry

What is a 1608 Infrared LED?

The 1608 infrared LED, also known as an SMD (Surface Mount Device) infrared LED, is a compact and efficient light source designed for various applications that require invisible light transmission. Measuring just 1.6mm x 0.8mm, the 1608 LED is significantly smaller than traditional infrared LEDs, making it ideal for space-constrained environments. Its compact size and high luminous intensity make it a popular choice for consumer electronics, automotive, and industrial applications.

Design and Technology

The 1608 infrared LED is constructed using advanced semiconductor technology. It consists of a small, round semiconductor chip encapsulated in a clear or yellow plastic lens, which helps to focus the infrared light in a specific direction. The lens material and shape are crucial in determining the beam angle and the intensity of the emitted light. These LEDs typically have a wavelength of around 940nm, which is within the near-infrared spectrum, making them invisible to the human eye.
