Principle of work of the present invention:
(1) as shown in Fig. 4 (a) ~ 5, when noon in summer, when sun altitude is larger (this sentences 65 ° for example), if indoor lighting uses without surface micro-nano structure daylighting glass (hereinafter referred to as common daylighting glass), then sunray is with the incident glass in 65 ° of angles, and it is indoor from the another side directive of glass with 65 ° of angles, solar energy is almost lossless, summer room temperature then can be caused more hot, and excessively strong light also easily cause the problems such as electrical equipment damages, furniture is aging;
And if indoor lighting uses the double-deck dimming glass of the present invention, then sunray is with the incident glass in 65 ° of angles, light layer inside glass after twice refraction with incident angle θ directive micro-nano structure, calculating is verified, within the scope of controlled intermediate refractive index layer and Zig-zag array structure (saw tooth like microstructures) base angle, the angle of total reflection i that incident angle θ will be greater than between the middle layer of Zig-zag array structure and pugging air contact interface c:
i c = arcsin n 1 n 2
Wherein, n 1for optically thinner medium refractive index, n 2for optically denser medium refractive index.
Then will there is total reflection phenomenon in the sunray of directive Zig-zag array structure, and then with the another side of incident angle γ directive Zig-zag array structure, continue secondary total reflection phenomenon occurs, finally return to outdoor.Thus significantly reduce and enter indoor sunray, effectively reduce sunlight strength, and then room temperature is kept a suitable scope.
(2) as shown in Fig. 6 (a) ~ 7, in time-division morning and afternoon in winter in spring and autumn, when sun altitude is less (this sentences 25 ° for example), if indoor lighting uses common daylighting glass, then sunray is with the incident glass in 25 ° of angles, indoor from the another side directive of glass with 25 ° of angles after birefringence, solar energy remains in a suitable scope, and indoor temperature is comfortable;
If indoor lighting uses the double-deck dimming glass of the present invention, then sunray is with the incident glass in 25 ° of angles, with incident angle θ directive micro-nano structure after birefringence, calculating is verified, within the scope of controlled intermediate refractive index layer and Zig-zag array structure base angle, the angle of total reflection i that incident angle θ will be less than between the middle layer of Zig-zag array structure and pugging air contact interface cthen can not there is total reflection phenomenon in the sunray of directive micro-nano structure, but directly by refraction action directive beam projecting layer glass, and then enter indoor, period, solar energy is almost lossless, and known double-deck dimming glass is in time-division morning and afternoon in winter in spring and autumn, sunlight strength can be remained in a suitable scope equally, ensure indoor Thermal comfort.
(3) as shown in Fig. 8 ~ 11, in time-division morning and afternoon in summer, when sun altitude is less (this sentences 40 ° for example), if use this double-deck dimming glass, but do not use its angle regulating function, then as shown in Fig. 8 ~ 9, sunray enters light layer glass with 40 ° of angles, with incident angle θ directive Zig-zag array structure after birefringence, the now angle of total reflection i that will be less than between the middle layer of Zig-zag array structure and pugging air contact interface of this incident angle θ cthen can not there is total reflection phenomenon in the sunray of directive Zig-zag array structure, but directly by refraction action directive beam projecting layer glass, and then enter indoor, solar energy is almost lossless, cause indoor to remain on a higher temperature, this double-deck dimming glass fails to play a role completely;
And if employ angle regulating function, then as shown in Figure 10 ~ 11, when sun altitude is 40 °, light will enter light layer glass with 55 ° of angles, with incident angle θ directive Zig-zag array structure after birefringence, the now angle of total reflection i that will be greater than between the middle layer of Zig-zag array structure and pugging air contact interface of this incident angle θ c, then will there is total reflection phenomenon in this sunray, finally return to outdoor, room temperature is reduced in a scope be comparatively suitable for.
(4) as shown in Figure 12 ~ 15, at the noon in winter in spring and autumn, when sun altitude is larger (this sentences 65 ° for example), if use this double-deck dimming glass, but do not use its angle regulating function, then as shown in Figure 12 ~ 13, sunray enters light layer glass with 65 ° of angles, with incident angle θ directive Zig-zag array structure after birefringence, the now angle of total reflection i that will be greater than between the middle layer of Zig-zag array structure and pugging air contact interface of this incident angle θ c, then will there is total reflection phenomenon in this sunray, finally return to outdoor, and cause room temperature to reduce, human body feels cold;
And if employ the angle regulating function of this double-deck dimming glass, then as shown in Figure 14 ~ 15, when sun altitude is 65 °, light will enter light layer glass with 51 ° of angles, with incident angle θ directive Zig-zag array structure after birefringence, the now angle of total reflection i that will be less than between the middle layer of Zig-zag array structure and pugging air contact interface of this incident angle θ c, can not there is total reflection phenomenon in this sunray, but directly by refraction action directive beam projecting layer glass, and then enter indoor, and solar energy is almost lossless, thus remained on indoor in a suitable temperature range.
In sum, apply this double-deck dimming glass as lighting for buildings parts, effectively can reduce fierce sunlight strength in summer, room temperature be controlled a suitable scope, also significantly can reduce the probability of happening of the problems such as electrical equipment damages and furniture is aging simultaneously, promote the quality of the life of the mankind; And in winter in spring and autumn, comparatively suitable sunlight strength also can not be weakened because of the existence of interlayer glass micro-nano structure, can continue to remain in a suitable scope, ensure that indoor Thermal comfort.
As mentioned above, just the present invention can be realized preferably.
Embodiments of the present invention are not restricted to the described embodiments; other are any do not deviate from Spirit Essence of the present invention and principle under do change, modification, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
