Introduction to LED 3mm Blue

LED 3mm blue is a type of LED with a diameter of 3mm, making it a compact and versatile lighting solution. These LEDs emit a bright and vibrant blue light, which is highly visible and eye-catching. The blue light is generated when electrons are excited and collide with the semiconductor material, releasing energy in the form of light. The color of the light emitted by an LED is determined by the energy band gap of the semiconductor material used. In the case of LED 3mm blue, the semiconductor material typically used is gallium nitride (GaN), which has a narrow energy band gap that allows it to emit blue light. The intensity of the blue light can be controlled by adjusting the forward voltage and current of the LED.
