Introduction to LED 940 nm

LEDs, or Light Emitting Diodes, are semiconductor devices that emit light when an electric current passes through them. The color and wavelength of the emitted light depend on the material used in the LED’s semiconductor layer. The 940 nm wavelength falls within the infrared spectrum, making it invisible to the human eye. This unique property makes 940 nm LEDs highly desirable for various applications, especially those requiring long wavelengths.

Characteristics of 940 nm LEDs

The following are some of the key characteristics of 940 nm LEDs:

1. Infrared Wavelength: As mentioned earlier, 940 nm LEDs emit light in the infrared spectrum, making them invisible to the human eye. This property is particularly useful in applications where the visibility of the light source is undesirable.

2. High Emission Efficiency: 940 nm LEDs are known for their high emission efficiency, which means they can convert a significant portion of the electrical energy into light. This characteristic makes them highly suitable for energy-efficient applications.

3. Long Life Span: 940 nm LEDs have a longer lifespan compared to other types of LEDs. This is due to the lower energy levels involved in the emission process, which reduces the risk of material degradation over time.

4. Low Heat Generation: 940 nm LEDs generate less heat compared to other types of LEDs, making them suitable for applications where heat dissipation is a concern.
