Infrared LED 3535, also known as an infrared emitting diode or IR LED, is a compact and efficient light source that emits infrared radiation. These devices are widely used in various applications, including remote controls, security systems, and communication systems. This article delves into the details of infrared LED 3535, exploring its features, applications, and the industry surrounding this technology.

Introduction to Infrared LED 3535

The infrared LED 3535 is a type of LED that emits infrared light in the 780 to 950 nanometer (nm) wavelength range. It is named "3535" due to its dimensions, which are 3.5mm x 3.5mm. These LEDs are typically made of gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) and are designed to emit infrared light efficiently. The compact size and high efficiency make them ideal for integration into various electronic devices.

How Infrared LED 3535 Works

Infrared LEDs work on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. When an electric current is applied to the semiconductor material in an infrared LED, electrons and holes recombine, releasing energy in the form of infrared light. The wavelength of the emitted light depends on the composition and structure of the semiconductor material. The 3535 package is designed to enhance the emission of infrared light. It typically consists of a flat top and a round lens that focuses the light into a narrow beam. This design allows for better control of the light output and directionality, making it suitable for applications that require precise targeting of infrared light.
