Definition for uv led strip
The ultraviolet rays are one of the electromagnetic wave, the electron atoms jump from the high-energy bands at low energy band, will release excess energy with electromagnetic waves . The stronger the energy of electromagnetic wave , the short the wave you can . the human can see that400nm-780nm（1nm=10-9m）,
The 400nm of electromagnetic wave will shows “ blue ” color,
The 780nm of electromagnetic wave will shows “orange” color.
The wavelength of ultraviolet rays are smaller than 400nm. The wavelength outside the ultraviolet rays area, , it is known as Ultraviolet, the wavelength of UV as 100-400nｍ, These rays would not be visible to our eyes. But the cameras can see what human eyes can ‘ t: The ultraviolet rays.
