Similarly, the second collimating lens array 203 is composed of a plurality of second collimating lenses 2031, wherein a surface of each second collimating lens 2031 close to the LED light source is a light incident surface, a surface of each second collimating lens far away from the LED light source is a light emitting surface, the light incident surface is a plane, and the light emitting surface is a spherical convex surface.
The first collimating lens 2011 and the second collimating lens 2031 are made of any transparent solid material, including but not limited to acrylic, glass, etc., and the transmittance of the lens is generally 90-93%, or in a larger range, such as more than 93% or less than 80%.
The lens array 202 is a plurality of black regular hexagonal prisms, is arranged in a honeycomb seamless splicing manner, and is arranged in one-to-one correspondence with the first collimating lens array 201 and the second collimating lens array 203.
As shown in fig. 9, the honeycomb core 3 is made of a black solid core material made of one of aluminum alloy, glass fiber fabric impregnated with resin, aromatic fiber paper, kraft paper, graphite fiber or kevlar fiber, and has light guiding and heat dissipating effects.
The diffusion plate 4 is made of PC, PMMA, or transparent glass and transparent toughened glass bonded with diffusion films, wherein the diffusion films are bonded on one surface of the transparent glass connected with the honeycomb core material, or the diffusion films are bonded on two surfaces of the transparent glass. The diffusion plate 4 has the main functions of converting an uneven light source into a surface light source with evenly distributed and fuzzy lattice points and simultaneously shielding honeycomb core materials or other optical defects; secondly, improve the visual angle, increase the light source softness, thirdly, support backlight framework to the optical material of above is impaired.
Specifically, the light transmittance of the diffusion plate 4 is generally required to be 85% to 90%, or 80% to 92%, or 75% to 95%. The haze of the diffusion plate 4 is generally required to be 65% to 75%, or 60% to 80%, or 55% to 85%.
The blue light scattering plate 5 is composed of a transparent substrate 501 and transparent titanium dioxide nanoparticles having different refractive indexes relative to the transparent substrate 501 and an average size significantly smaller than the wavelength of visible light, and the titanium dioxide nanoparticles have the functions of absorbing and suppressing ultraviolet rays, self-cleaning, purifying air, and the like.
As an embodiment of the present invention, as shown in fig. 10, titanium dioxide nanoparticles 502 are uniformly embedded in a transparent substrate 501, and the transmitted white light is absorbed and suppressed by the titanium dioxide particles 502 in the transparent substrate 501, and long wave components in the sunlight are filtered, so that blue light and violet light penetrate a blue light scattering plate 5.

Blue light scattering can be explained by Rayleigh scattering, and since the intensity of Rayleigh scattering is inversely proportional to the fourth power of wavelength, the red light has longer wavelength, the scattered red light has weaker intensity, and the blue and purple light has shorter wavelength and stronger scattering intensity. Therefore, the atmospheric molecules are better than a filter screen, the components of long waves in sunlight are filtered out, and the rest blue and purple lights are sprayed to the ground. The human eye is very insensitive to violet light and therefore the sky presented is blue.
In order to meet the Rayleigh scattering requirement, the diameter d of the nanoparticle must be much smaller than the wavelength λ of the incident light, typically the upper bound is about 1/10 of the wavelength of blue light, e.g. 48nm, where the diameter d of the nanoparticle may be 40nm, 30nm, 20nm, 10nm or 5nm.
As shown in fig. 2, the light emitted from the LED light source array is collimated into parallel light after passing through the collimator lens array 2. The parallel light is guided to the diffusion plate 4 through the honeycomb core 3, so that the light is more uniform and softer. Directly above the observer, the sun 6 (warm light) formed by the parallel light passing through the partial honeycomb core 3 in the visual field is seen, while the light in other areas is blocked by the honeycomb core, and the blue sky (cool light) formed by the blue light scattering plate 5 is seen.
The invention introduces the diffusion blue sky and the virtual sun into the indoor space, can realize an illumination system, a medical system and an air purification system, can be applied to indoor illumination, such as home illumination, underground malls, parking lots, meeting rooms, office buildings and other places needing illumination, and can also be applied to auxiliary treatment of depression, such as hospitals, rehabilitation centers, medical research institutions and other places.

Therefore, the protection scope of the invention is subject to the protection scope of the claims.
