Description of LED Emitters

LED Emitters are a class of semiconductor devices that produce light when an electric current passes through them. This group encompasses Infrared (IR), Ultraviolet (UV), and Visible light emitters.

LED Emitters

1. Infrared (IR) LEDs: Emit light in the invisible spectrum to humans, with wavelengths typically between 700-800 nanometers (nm) and 1 millimeter (mm).

applications:

Optical Communication: Used in fiber optic communication and data transmission.

Remote Controls: Commonly used in remote controls for consumer electronics.

Night Vision: Employed in night vision devices for military and security applications.

2. Ultraviolet (UV) LEDs: Emit light outside the visible spectrum, with wavelengths ranging from approximately 200 nm to 400 nm.

applications:

Sterilization: Effective in killing bacteria and viruses, used in air and water purification systems.

Curing: Used in the curing of adhesives and coatings in industrial processes.

Forensics: Employed in forensic analysis for document examination and evidence detection.

3. Visible LEDs: Emit light within the range visible to the human eye, from about 400 nm to 700-800 nm.

appllications:

General Illumination: Used in household and commercial lighting for energy savings.

Signage and Displays: High brightness LEDs used in electronic signage and scoreboards.

Automotive Lighting: Used in vehicle headlights, taillights, and interior lighting.

How to select right LED emitters?

These LED emitters can be categorized and selected based on several parameters, such as:

• Type: Infrared, Ultraviolet, or Visible.
• Forward Current: The current required to operate the LED at its specified intensity.
• Wavelength: The specific color or frequency of light emitted.
• Viewing Angle: The range of angles at which the light can be effectively seen.
• Forward Voltage: The voltage needed to drive the LED at the specified current.
• Operating Temperature: The temperature range within which the LED operates efficiently.
• Other Factors: Including color rendering index, brightness, and lifespan.
