In this article, we will delve into the world of infrared LED 3535, exploring its characteristics, applications, and the market trends surrounding this technology.

Introduction to Infrared LED 3535

The 3535 size refers to the dimensions of the LED, which are 3.5mm in length and 3.5mm in width. These compact dimensions make them ideal for space-constrained applications where traditional larger LEDs would not fit. Infrared LEDs are available in different colors, with the most common being red, amber, and near-infrared, which are invisible to the human eye.

How Infrared LED 3535 Works

Infrared LED 3535 operates on the principle of the photoelectric effect. When an electric current passes through the semiconductor material, it generates heat, which is dissipated into the environment. As a result, the electrons in the material gain energy and move to a higher energy state. When these electrons return to their original state, they release energy in the form of light. In the case of infrared LEDs, this light is in the infrared spectrum, which is not visible to the human eye.
