Description

Sky lamp with dynamic imaging function

Technical Field

The utility model relates to the technical field of sky lights, in particular to a sky light with a dynamic imaging function.

Background

Sky light is a kind of flat lamp, and when light source irradiates on rayleigh board to generate optical phenomenon of rayleigh scattering, particle size is far smaller than incident light wavelength (less than tenth of wavelength), scattered light intensity in each direction is different, and the intensity is inversely proportional to fourth power of incident light wavelength, which phenomenon is called rayleigh scattering. Because the intensity of Rayleigh scattering is inversely proportional to the fourth power of the wavelength, blue-violet light with shorter wavelength in solar spectrum is more obvious than red light with longer wavelength, and blue light energy is the largest in short wave, so that blue light is scattered to diffuse sky under the strong scattering action of atmospheric molecules when rainy weather or autumn is high and fresh (coarser particles in the sky are fewer and molecular scattering is the main), and the sky is blue; meanwhile, the Rayleigh scattering plate is also used for optimizing the spectrum and guaranteeing the healthy and transparent effect of lamplight.

Compared with the existing flat lamp, the sky lamp realizes better illumination effect through Rayleigh scattering, but the existing sky lamp simulates a static sky and meets illumination requirements, or realizes shading or color change through dimming, and is difficult to present dynamic change or imaging, for example: the simulated sky has single functions and insufficient presentation, and is difficult to meet the requirements of users.
