Technical Field

Background

Rayleigh scattering is an optical phenomenon, called rayleigh scattering, in which the intensity of scattered light in various directions is different at a particle scale much smaller than the wavelength of incident light (smaller than one tenth of the wavelength), and is inversely proportional to the fourth power of the wavelength of incident light. Because the intensity of Rayleigh scattering is inversely proportional to the fourth power of the wavelength, blue-violet light with shorter wavelength in the solar spectrum is more obviously scattered than red light with longer wavelength, and the energy of the blue light is the largest in the short wave, so that when raining and raining, the sky is cool (the number of thicker particles in the sky is less, and the molecular scattering is the main factor), under the strong scattering action of atmospheric molecules, the blue light is scattered to the diffuse sky, and the sky is blue. With the pursuit of people for high-quality light and the progress of lighting technology; sky lights which can show blue sky are increasingly popular in the industry.

In the prior art, the following technical problems in the aspect 2 exist:

1. light rays cannot be uniformly distributed on the Rayleigh effect plate, light emitted by the lamp is not uniform, light emitted on the Rayleigh effect plate is not uniform, and clear sky vision effect generated by the sky lamp is poor. Especially, in the case of a large-sized lamp, it is difficult to form a uniform blue sky effect.

2. The light emitted from the light source from the inside of the lamp box can partially irradiate on the light receiving area of the box body to generate harmful reflection, so that the light emitting of the lamp is deteriorated. In order to solve the technical problems, the patent numbers are as follows: the utility model ZL202122252093.5 discloses: a lighting device comprises a box body, a light source module, a light-emitting plate and a light extinction structure. The box includes roof and bounding wall, the first end of bounding wall with the roof is connected, the second end of bounding wall forms the light-emitting window, the central line of bounding wall with the roof slope sets up. The light source module is arranged in the box body. The light emitting plate is arranged at the light emitting opening. The extinction structure is arranged on the light receiving area of the inner wall of the box body. When part of light rays radiated from the inside of the box body to the outside of the light source module irradiate on the light receiving area of the box body, the extinction structure is used for absorbing the part of light rays and reducing the reflection of stray light rays to the light emitting plate, but the technology is the same as the technology for eliminating harmful light rays; the utilization efficiency of light is reduced, and then the energy efficiency of the lamp product is reduced.
