This article will introduce the industry of high power violet LED, including its basic principles, market trends, and application prospects.
Basic Principles of High Power Violet LED
High power violet LED is a semiconductor device that emits violet light. It is composed of a semiconductor material, a p-n junction, and an encapsulation layer. When the semiconductor material is excited by an external electric field, electrons and holes recombine, releasing energy in the form of light. The color of the light emitted depends on the energy gap of the semiconductor material.
The energy gap of the semiconductor material is the energy difference between the valence band and the conduction band. The smaller the energy gap, the shorter the wavelength of the emitted light. The energy gap of the semiconductor material in high power violet LED is typically in the range of 2.0-2.2 eV, which corresponds to the violet light region.
