Introduction to 3535 Infrared LED Industry

What is a 3535 Infrared LED?

The 3535 infrared LED, also known as a 3535 infrared diode, is a type of semiconductor device that emits infrared light. It is named after its physical dimensions, which are typically 3.5mm in width and 3.5mm in length, hence the name "3535". These LEDs are widely used in various applications due to their compact size, high efficiency, and cost-effectiveness. The infrared light emitted by these LEDs is invisible to the human eye, making them ideal for applications that require covert or hidden signaling.

Working Principle of 3535 Infrared LED

The 3535 infrared LED operates based on the principle of electroluminescence. When an electric current is applied to the semiconductor material, it generates heat, which excites the electrons within the material. As the electrons return to their ground state, they release energy in the form of photons. In the case of infrared LEDs, these photons are in the infrared spectrum, which is outside the visible light range for humans. The semiconductor material used in 3535 infrared LEDs is typically a compound semiconductor, such as AlGaAs (Aluminum Gallium Arsenide) or GaAs (Gallium Arsenide). These materials have a direct bandgap, which allows for efficient emission of infrared light when excited by an electric current.
