Introduction to 1608 Infrared LED Technology

What is a 1608 Infrared LED?

The 1608 infrared LED, also known as a 1608 IR LED, is a compact and efficient light-emitting diode that emits infrared light. It is named after its dimensions, which are 1.6mm x 0.8mm, making it one of the smallest types of infrared LEDs available on the market. These LEDs are widely used in various applications due to their small size, low power consumption, and reliable performance. Infrared LEDs work by converting electrical energy into infrared light, which is a type of electromagnetic radiation with longer wavelengths than visible light. This light is not visible to the human eye but can be detected by sensors and other electronic devices. The 1608 infrared LED is particularly well-suited for use in proximity sensors, remote controls, and other applications where a small, low-cost, and energy-efficient light source is required.

How Does a 1608 Infrared LED Work?

The operation of a 1608 infrared LED is based on the principle of the semiconductor diode. When an electrical current is applied to the diode, electrons and holes recombine at the junction, releasing energy in the form of photons. In the case of an infrared LED, these photons have wavelengths that fall within the infrared spectrum, which is why the light is not visible to the naked eye. The 1608 infrared LED is typically made from gallium arsenide (GaAs) or similar semiconductor materials, which are chosen for their ability to efficiently emit infrared light. The LED is encapsulated in a clear or infrared-transmitting lens to focus the light into a narrow beam. This design ensures that the infrared light is directed towards the intended target, such as a sensor or receiver.
