UVB — ultraviolet uv LED strip is the wavelength of 100 nm to 280 nm, which is of great value in the field of sterilization, medical, biochemical detection, high density information storage and secure communication. Compared with the mercury lamp UV light source, based on aluminum gallium nitride (AlGaN) materials ultraviolet light-emitting diode (LED) has the following advantages：Strong, energy saving, long service life, no mercury and environmental protection etc. UVB LED is gradually infiltrated into the traditional application fields of mercury lamp.At the same time, many other applications can now benefit from UVB LED.such as the white home appliances disinfection module, portable water purification system, mobile phone disinfection, etc., thus showing a broad market prospects, becoming the semiconductor lighting LED, the new hot spot of global LED research and investment.it’s  became global LED research and investment new hotspot in subsequent semiconductor lighting Research Report shows that the future of the LED market may be divided into two parts, one for general lighting visible LED; other is a high-tech innovation as the characteristics of UVB ultraviolet LED.Compared with visible LED, the luminous efficiency and the optical output power of UVB ultraviolet LED are lower than visible LED at present. But now we use the nano scale technology to produce nano pattern substrate,not only improved the quality of materials, but also improve the light extraction efficiency.

280 nm ultraviolet LED @ 20 mA current, the output power of the optical output reached more than 3 MW,can also optimize the packaging process, making deep UV LED light beads encapsulated can be achieved morethan 4 mW optical output power.
