Each described sawtooth unit 1 includes multiple sawtooth, any two adjacent described sawtooth unit 1
In the varying in size of angle of work surface and bottom surface of described sawtooth；Luminescence unit 2 energy
Enough on the work surface of described sawtooth, irradiate directional light according to certain incident angle, so that shining
It is incident upon on the sawtooth work surface of any two adjacent described sawtooth unit 1, spreads out through reflection
The color of the light of injection is different.At this it should be noted that each sawtooth of the present embodiment
Unit can be formed in substrate, it is also possible to is created as the structure of one.
Being not difficult to find out, the multiple sawtooth unit 1 in the present embodiment constitute existing skill
Echelle grating (also known as reflective echelon) in art, in the present embodiment, profit
With the dispersion characteristics of echelle grating, the light that luminescence unit 2 is emitted, pass through
Reflection diffraction goes out the light of other color.
Concrete, if expecting the light of three kinds of different colours of red, green, blue, luminous single
2 light sent of unit are white light, according to echelle grating equation m λ=2dsin θ, wherein,
M is the order of diffraction time, and λ is diffraction wavelength, and d is grating constant, and θ is that blaze angle (glitters
Angle is the work surface of sawtooth and the angle of bottom surface), now luminescence unit 2 is issued
White light then can go out the light of a kind of wavelength according to blaze angle θ diffraction, and a kind of wavelength
Light then represents the light of a kind of color, to those skilled in the art, red, green, blue
Wavelength corresponding to the light of three kinds of different colours is knowable, therefore can be pre-designed out
The size of the blaze angle θ corresponding with these three wavelength, namely shown in Fig. 1, each
