LED wavelength options have become an essential aspect of the lighting industry, offering a wide range of possibilities for different applications. With advancements in technology, the availability of various wavelengths has expanded, allowing for more tailored lighting solutions. This article delves into the different LED wavelength options available in the market and their applications.

Introduction to LED Wavelengths

LEDs (Light Emitting Diodes) emit light at specific wavelengths, which determine the color of the light they produce. The color spectrum of LEDs ranges from ultraviolet (UV) to infrared (IR), with visible light falling between these two extremes. LED wavelength options have been carefully engineered to cater to various lighting needs, from general illumination to specialized applications.

Visible Light LED Wavelengths

Visible light LEDs are the most commonly used in everyday applications. They produce light in the range of 380 to 780 nanometers (nm), which corresponds to the colors of the rainbow. The following are some of the most popular visible light LED wavelengths: -

Red (620-750 nm): Red LEDs are widely used in indicator lights, emergency vehicle lights, and red lasers.

-

Orange (590-620 nm): Orange LEDs are used in traffic lights, exit signs, and as indicator lights.

-

Yellow (570-590 nm): Yellow LEDs are used in traffic lights, safety signs, and as indicator lights.

-

Green (495-570 nm): Green LEDs are used in indicator lights, traffic lights, and as indicator lights.

-

Blue (450-495 nm): Blue LEDs are used in indicator lights, display screens, and as indicator lights.

-

White (380-780 nm): White LEDs are produced by mixing different colors of light, such as blue, green, and red. They are used in general lighting, display screens, and as indicator lights.

UV and IR LED Wavelengths

UV and IR LEDs are used in specialized applications due to their unique properties. The following are some of the most popular UV and IR LED wavelengths: -

Ultraviolet (UV) LEDs (380-380 nm): UV LEDs are used in forensic analysis, counterfeit detection, and curing adhesives.

-

Visible Light (380-450 nm): These LEDs are used in medical applications, such as photodynamic therapy, and in security systems.

-

Infrared (IR) LEDs (780-2500 nm): IR LEDs are used in remote controls, infrared sensors, and as indicator lights.
