Introducing the infrared LED 3535, a compact and highly efficient light source that has become a staple in various applications across industries. This article delves into the details of the infrared LED 3535, its features, applications, and the impact it has on the industry.

What is an Infrared LED 3535?

An infrared LED 3535, also known as an IR3535, is a type of light-emitting diode (LED) that emits infrared light. The "3535" refers to the physical dimensions of the LED, which are 3.5mm in width and 3.5mm in height. These LEDs are designed to emit light in the infrared spectrum, which is not visible to the human eye. They are commonly used in applications where invisible light is required for communication, sensing, or illumination.

How Does an Infrared LED 3535 Work?

Infrared LEDs work on the principle of electroluminescence, where an electric current is applied to a semiconductor material, causing it to emit light. The semiconductor material used in infrared LEDs is typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). When an electric current passes through the semiconductor, it excites electrons, which then recombine with electron holes, releasing energy in the form of infrared light. The color of the light emitted by an infrared LED is determined by the energy band gap of the semiconductor material. The 3535 size LEDs typically emit light in the near-infrared range, which is between 780nm and 1000nm. This range is particularly useful for applications that require invisible light, such as remote controls, security systems, and wireless communication.
