the Infrared & Ultraviolet of some parameters

Infrared:

frequency range in normal status: 10^12–3.9*10^14 Hz
wavelength range in vacuum: 3*/10^-1—7.7*10^-7 m
Vision light:

frequency range in normal status: 3.9*10^14–7.5*10^14 Hz
wavelength in vacuum: 7.7*10^-7—4*10^-7 m
Ultraviolet:

frequency range in normal status: 7.5*10^14—5*10^16 Hz
wavelength in vacuum: 4*10^-7—6*10^-9 m
The list can also be sorted by frequency range between there tree
Infrared < Vision light< Ultraviolet(the sort data are appropriate for uv led strip )
The list can also be sorted by wavelength range between there tree
Infrared > Vision light> Ultraviolet

The reason for this is that affects led light

*The Material Factor to Affects LED light Quality. light attenuation rapidly.

*The junction temperature of LED has directly influence LED light output efficiency,

*The wrong drive way:LED needs constant-current drive, if you are assuming an incorrect drive way, the led light attenuation rapidly.
