Problems solved by technology

[0002] Today, with the rapid development of society, people are still pursuing aesthetics while meeting basic lighting needs. Therefore, many existing lighting fixtures have changed from simply providing lighting functions to aesthetics and appreciation. It becomes a composite lighting fixture. When the existing light source is used for lighting, when the light generated by the light source produces a light and shadow pattern, the pattern is not clear enough, the brightness is not enough, and the boundary is blurred. Not enough light

Abstract

The invention discloses a method for generating a shadow pattern through light source illumination. A light source device capable of generating hemispheric light is arranged on the bottom face. Light emitted by the light source device on the bottom face is emitted to a target face through a shadow transmitting and scattering device to illuminate the target face, and therefore the shadow pattern is formed on the target face. The shadow transmitting and scattering device is of a surrounded structure so that the light emitted by the light source device can be converged, and the shadow transmitting and scattering device is provided with a plurality of transmitting structures and a plurality of scattering structures. The transmitting structures are used for generating the shadow pattern and the scattering structures are used for illuminating the whole target face. According to the method for generating the shadow pattern through light source illumination, the shadow pattern generated through projection of the shadow can be made to be clear, a boundary is clear, it can be guaranteed that the face generating the shadow pattern has the enough illumination degree, and a person feels that the light is soft and comfortable.

Description

technical field [0001] The present invention relates to the technical field of lighting, and more specifically, to a method for generating light and shadow patterns by lighting with a light source. Background technique [0002] Today, with the rapid development of society, people are still pursuing aesthetics while meeting basic lighting needs. Therefore, many existing lighting fixtures have changed from simply providing lighting functions to aesthetics and appreciation. It becomes a composite lighting fixture. When the existing light source is used for lighting, when the light generated by the light source produces a light and shadow pattern, the pattern is not clear enough, the brightness is not enough, and the boundary is blurred. Not enough light. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art, and provide a method for generating light and shadow patterns by light source illumination. Soft and co...
