Introduction to 3535 Infrared LEDs
The 3535 Infrared LED, also known as a 3535 SMD infrared LED, is a surface-mounted device (SMD) that measures 3.5mm by 3.5mm. Despite its small size, it packs a significant amount of power, making it an ideal choice for compact and energy-efficient applications. The "3535" refers to the dimensions of the LED, which are 3.5mm in length and width.
How 3535 Infrared LEDs Work
3535 Infrared LEDs work by converting electrical energy into infrared light. When an electric current passes through the LED, it excites the electrons within the semiconductor material, causing them to recombine and release energy in the form of light. In the case of infrared LEDs, this light is in the infrared spectrum, which is beyond the visible range of human eyes.
The key to the 3535 Infrared LED's functionality lies in its semiconductor material, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). These materials have a direct bandgap, which allows them to efficiently emit infrared light when an electric current is applied.
