[0023] Specifically, Rayleigh scattering plate 22 selects Rayleigh scattering light guide plate with thickness 3-10mm, and blue sky module 2 is wrapped into a module by metal aluminum 23.In order to improve the effect of deep blue sky, semi-reflective and semi-transmissive plate 24 can be provided on the back of Rayleigh scattering plate 22, the thickness of semi-reflective and semi-transmissive plate 24 is 2-4mm, the light transmittance is 50%, the reflectivity is 50%, the first light source 21 is placed on the side edge of Rayleigh scattering plate 22 in the form of side light emission, the color temperature of the used light source is 6880-8100K, the main wavelength is 484nm, the red ratio is 15.1%, the green ratio is 78.2%, and the blue ratio is 6.6%.When the light source is started, light enters Rayleigh scattering plate 22, and scattering occurs on the surface of micro-nano particles in the interior of Rayleigh scattering plate 22, so that the light emitting surface presents the effect of blue sky.At this time, the light emitting surface is tested by using an illuminometer, and the red ratio, the green ratio and the blue ratio are 12.6%, 35.9% and 51.5% respectively, and the blue ratio is greatly improved.Partial light is refracted downward to semi-reflective and semi-transmissive plate 24, and semi-reflective and semi-transmissive plate 24 is single-coated, and partial light is refracted into the plate and then reflected in multiple stages, so that the visual effect of superimposed blue sky effect is generated when the lamp is observed by the human eye, the three-dimensional effect is better, and the sky effect is more transparent.The outermost plate is transparent plate 25 with high light transmittance, which mainly protects Rayleigh scattering plate 22 from dust and scratches without affecting the main light emitting effect.

[0024] In the embodiment, the edge of the Rayleigh scattering plate 22 is provided with a mirror surface reflection structure 3 perpendicular to the Rayleigh scattering plate 22. When the blue sky module 2 is lit, the light emitted by the Rayleigh scattering plate and the semi-reflective and semi-transmissive plate 24 is reflected by the mirror surface reflection structure 3, and the mirror surface reflection structure 3 around the human eye is observed as the reflection of the bottom blue sky module 2.
