UV purple LED lamp, as a cutting-edge lighting technology, has been gaining increasing attention in various industries. This article aims to provide an in-depth introduction to UV purple LED lamps, covering their definition, working principle, applications, advantages, and future prospects. By the end of this article, readers will have a comprehensive understanding of UV purple LED lamps and their significance in the industry.

Definition and Classification of UV Purple LED Lamps

UV purple LED lamps are a type of LED lighting equipment that emits purple light with a wavelength of 380-450nm. They are widely used in various fields, such as printing, curing, and medical treatment. According to the light-emitting principle, UV purple LED lamps can be divided into two types: phosphor-converted UV purple LED lamps and direct-emission UV purple LED lamps.

Working Principle of UV Purple LED Lamps

The working principle of UV purple LED lamps is based on the photoelectric effect. When an electric current passes through the LED chip, electrons and holes are generated, which recombine to emit photons. The photons with a wavelength of 380-450nm are purple light. In the process of emitting light, the LED chip may be coated with a phosphor layer to convert the blue light emitted by the LED chip into purple light.
