5mm Blue LED Lights: Enhance Your Project with Top Quality!

With the rapid development of technology and the increasing demand for high-quality lighting, the 5mm blue LED has become a hot topic in the industry. As a high-efficiency and energy-saving light source, the 5mm blue LED has been widely used in various fields, such as mobile phone screens, LED displays, and automotive lighting. This article will introduce the 5mm blue LED from several aspects, including its basic principles, application fields, and market trends.

Basic Principles of 5mm Blue LED

The 5mm blue LED is a semiconductor light-emitting diode with a diameter of 5mm. It is made of gallium nitride (GaN) as the main material, which has the advantages of high efficiency, low power consumption, and long service life. The working principle of the 5mm blue LED is based on the semiconductor physics.

When the forward bias voltage is applied to the LED, electrons and holes are injected into the active region. Under the action of the electric field, the electrons and holes recombine, releasing energy in the form of light. The color of the light emitted by the LED is determined by the energy band gap of the semiconductor material. The energy band gap of gallium nitride is about 3.4eV, so the 5mm blue LED emits blue light.
