UV Diode LED, or Ultraviolet Diode LED, is a type of light-emitting diode that emits ultraviolet light. It has been widely used in various fields such as industrial processing, medical treatment, and environmental protection. This article will introduce the industry of UV Diode LED, including its working principle, types, applications, and market prospects.
Working Principle of UV Diode LED
The working principle of UV Diode LED is based on the semiconductor physics. When the forward bias voltage is applied to the PN junction of the semiconductor material, the electrons and holes are recombined in the active region, releasing energy in the form of photons. The energy of the photons is determined by the energy gap of the semiconductor material. For UV Diode LED, the energy gap is relatively large, so it emits UV light.
Types of UV Diode LED
According to the wavelength of the emitted light, UV Diode LED can be divided into three types: short-wave UV (SW-UV), medium-wave UV (MW-UV), and long-wave UV (LW-UV). Short-wave UV has a wavelength of 200-280nm, medium-wave UV has a wavelength of 280-400nm, and long-wave UV has a wavelength of 400-1000nm. The application fields of these three types of UV Diode LED are different due to their different wavelengths.
