发明名称 Lighting apparatus
摘要 A lighting apparatus is for use with a projection-receiving surface. The lighting apparatus includes a light-filtering assembly configured to block transmission of a first amount of light emitted by a light source towards the projection-receiving surface. This is done in such a way that blocked transmission of the first amount of light forms a projected shadow region on the projection-receiving surface. The light-filtering assembly is also configured to permit transmission of a second amount of light emitted by the light source towards the projection-receiving surface. This is done in such a way that transmission of the second amount of light forms a projected glow region on the projection-receiving surface. A filter-moving assembly is configured to move the light-filtering assembly. This is done in such a way that the projected shadow region and the projected glow region move and combine to form a variable curved wave pattern.

主权项 1. A lighting apparatus for use with a projection-receiving surface, the lighting apparatus comprising: a housing assembly forming an interior housing chamber, and the housing assembly also forming a projection opening leading to the interior housing chamber, and the projection opening being configured to face the projection-receiving surface once the housing assembly is positioned to do just so; a light source being positioned in the interior housing chamber of the housing assembly, and the light source being configured to emit light through the projection opening of the housing assembly toward the projection-receiving surface once the light source is positioned and activated to do just so; a light-filtering assembly being positioned in the interior housing chamber of the housing assembly between the projection opening and the light source, and the light-filtering assembly being configured to: (A) block transmission of a first amount of light being emitted by the light source through the projection opening towards the projection-receiving surface in such a way that blocked transmission of the first amount of light being emitted by the light source, in use, forms a projected shadow region positioned on the projection-receiving surface; and (B) permit transmission of a second amount of light being emitted by the light source through the projection opening towards the projection-receiving surface in such a way that transmission of the second amount of light being emitted by the light source, in use, forms a projected glow region positioned on the projection-receiving surface; and a filter-moving assembly being positioned in the interior housing chamber of the housing assembly, the filter-moving assembly being coupled to the light-filtering assembly, and the filter-moving assembly being configured to move the light-filtering assembly in such a way that the projected shadow region and the projected glow region positioned on the projection-receiving surface move and combine to form a variable curved interference pattern while the light-filtering assembly is moved just so; and a light controller being configured to be coupled to the light source via a control wire, and the light controller also being configured to control an amount of a type of light emitted by the light source; and the light controller being configured to facilitate focusing of a projected image to be casted onto the projection-receiving surface.
