Over the years, the 3mm LED diode has undergone continuous technological innovation, and its performance has been greatly improved.

Technology of 3mm LED Diode

The 3mm LED diode is a semiconductor device that emits light when an electric current passes through it. The core component of the 3mm LED diode is a semiconductor material, typically gallium nitride (GaN) or silicon carbide (SiC), which emits light when excited by electrons. The following are the key factors that affect the performance of a 3mm LED diode:

• Wavelength: The color of the emitted light is determined by the wavelength of the emitted photons. The 3mm LED diode can emit light in a variety of colors, including red, green, blue, and white.
• Brightness: The brightness of the 3mm LED diode is determined by the number of photons emitted. The brightness of a 3mm LED diode can range from a few millivolts to several tens of millivolts.
• Efficiency: The efficiency of a 3mm LED diode refers to the ratio of the electrical power input to the light output. The higher the efficiency, the less power the 3mm LED diode consumes.
• Lifetime: The lifetime of a 3mm LED diode refers to the time it takes for the brightness to decrease to 70% of its initial value. A longer lifetime means a more durable 3mm LED diode.
