Introduction to Power LED UV
Power LED UV refers to the use of high-power UV light-emitting diodes (LEDs) in various applications, including curing, sterilization, and disinfection. Unlike traditional UV lamps, power LED UV technology offers numerous advantages, such as energy efficiency, longer lifespan, and compact size. This section will delve into the basics of power LED UV technology and its working principles.
Working Principles of Power LED UV
The working principle of power LED UV technology is based on the excitation of electrons in a semiconductor material, which results in the emission of UV light. When a high-power LED is powered on, electrons are excited and move from the valence band to the conduction band, creating a flow of electricity. As electrons return to the valence band, they release energy in the form of UV light.
The UV light emitted by power LED UV lamps is mainly in the 200-400 nm range, with a peak at around 254 nm. This range of UV light is particularly effective in curing coatings, inactivating microorganisms, and other applications. The energy density of power LED UV lamps can reach up to 100 mW/cm², making them highly efficient and suitable for various applications.
