Method for generating light and shadow patterns by light source illumination

Abstract

The invention discloses a method for generating a shadow pattern through light source illumination. A light source device capable of generating semi-spherical light is arranged on the bottom face, light emitted by the light source device on the bottom face passes through a shadow transmission and scattering device to be irradiated to the target face to illuminate the target face, and the shadow pattern is formed on the target face. The shadow transmission and scattering device is provided with a surrounding type structure to converge the light emitted by the light source device, the surrounding type structure is a seamless cylinder made of metal, and the cross section of the seamless cylinder is in a circle shape or an oval shape or a regular polygon shape or a rectangle shape. The minimum distance between the light source device to the lateral wall of the seamless cylinder is D, the height of the seamless cylinder is H, the power of the light source device is P, and the adjustment constant is K, wherein P=(H / D)*K, the D is larger than or equal to 40 and smaller than or equal to 200, the H is larger than or equal to 400 and smaller than or equal to 4000, and the K is larger than or equal to 1.4 and smaller than or equal to 2.5. According to the method for generating the shadow pattern through light source illumination, the shadow pattern generated by shadow projection can be clear, and boundaries are not dim.

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 shortcomings of the prior art, and provide a method for generating light and shadow patterns by light source illumination, which produc...
