Revolutionizing Lighting Technology: Unveiling the Power of High Power Violet LED Lamp

High power violet LED lamp, as the name suggests, is a type of LED lamp with high luminous power and emits violet light. In recent years, with the continuous development of LED technology, high power violet LED lamps have been widely used in various fields. This article will introduce the industry of high power violet LED lamps, including their basic principles, application fields, and market prospects.

Basic Principles of High Power Violet LED Lamps

High power violet LED lamps are based on the principle of light-emitting diodes (LEDs). LEDs are semiconductor devices that can convert electrical energy into light energy. When an electric current passes through a semiconductor material, electrons and holes are recombined, releasing energy in the form of light. The color of the light emitted by an LED is determined by the energy gap of the semiconductor material used.

The violet light emitted by high power violet LED lamps is generated by using a semiconductor material with a small energy gap, typically gallium nitride (GaN) or aluminum gallium nitride (AlGaN). The energy gap of GaN is about 3.4 eV, and the energy gap of AlGaN is about 2.5 eV. When the electrons and holes recombine in these materials, they release energy in the form of violet light.
