Detailed description of the invention
Guiding device includes glass light guide plate 10, LED 40, pcb board 50 as shown in Figure 1, and light bar 40 is positioned at pcb board 50
On, it being placed in the side of glass light guide plate 10, the light that LED 40 sends enters glass light guide plate from the side of glass light guide plate 10
10, from exiting surface out.A layer thickness 10um-30um, the plating of reflectance more than 95% are set in the bottom surface of glass light guide plate 10
Silver layer, the light that LED 40 sends enters light guide plate from side, enters the light in light guide plate due to direct reflection effect 99% light
It is reflected to exiting surface.Compare increase reflector plate bottom light guide plate, owing to total reflection and refraction action only have 50% light by instead
Being mapped to exiting surface, the light transmission bottom surface and the air layer that are not reflected back toward exiting surface produce partition losses due to reflection, refraction, arrive
Some loss understood by reflector plate, and light is reflected back bottom surface again can some loss at air and glass interface reflection, refraction.
This utility model utilizes direct reflection that 99% luminous reflectance of directive bottom surface is returned back out bright finish, it is to avoid light is in the reflected refraction of multiple interfaces
Causing damage, comparing bottom surface increases reflector plate, and this utility model light utilization increases by 20%～40%.
Quantum Dot Glass light guide plate is as in figure 2 it is shown, arrange quantum dot light conversion layer at Quantum Dot Glass light guide plate exiting surface

Amount to poly resin and add light diffusing agent.Described light diffusing agent comprises siloxane type polymers particle, acrylic polymer particle, carbon
One or more mixing in acid calcium, barium sulfate, silicon oxide, titanium oxide.
The coating of light diffusion layer 20 is that subregion is carried out, as shown in Figure 4, Jin Guang district 11 brightness too high and away from Jin Guang district
12 brightness are too low, and in the case of therefore in hybrid resin, light diffusion particle concentration is identical, the coating number of times in Jin Guang district 11 is more than
Away from the coating number of times in Jin Guang district 12, or coating number of times constant in the case of, light diffusion particle in the hybrid resin in Jin Guang district 11
Concentration more than away from light diffusion particle concentration in the hybrid resin in Jin Guang district 12, thus realize improving away from Jin Guang district 12 brightness and
Reducing Jin Guang district 11 brightness, away from entering, light regional luminance generally ratio is relatively low, by reducing this region coating number of times or coating number of times
Diffusion particle concentration in constant reduction hybrid resin, further produces optical microstructures as shown in Figure 3 on this surface, increases
Amount of light, makes this regional luminance increase by 30%～50%, and the whole exiting surface uniformity brings up to more than 95%.
Can only carry out luminance-reduction operation or luminance raising operation, or according to specific requirement subregion carry out luminance-reduction and
Luminance raising operates.
The side view of Quantum Dot Glass light guide plate 10 is planar shaped or curve form, the minimum 1-2mm of thickness, can enter by one side
Light, two-sided enter light or multiaspect enter light；The front view of Quantum Dot Glass light guide plate 10 be shaped as rectangle, circle, polygon or other
Abnormity.
The manufacture method of Quantum Dot Glass light guide plate, comprises the following steps:
S1: the one side at glass light guide plate carries out roughening treatment；
S2: coating quantum dot light conversion layer on the surface of roughening treatment；
