Abstract

A color effect light or lamp with a three-dimensionally extending transparent lampshade on which luminous areas of various forms and colors are to be produced. A light mixing and reflecting body having an effective three-dimensionally shaped outside-surface is at least partially surrounded by the transparent lampshade. Differently colored illuminants whose brightness can be regulated separately are provided to illuminate the outside-surface of the light mixing and reflecting body, and spaced from one another. Preferably, each illuminant includes directing member for concentrating or focusing the light into a homogeneously coloured light beam, and is adjusted to cast its light beam in a direction to the effective outside-surface of the light mixing and reflecting body where differently colored light beams meet one another and are transformed by additional mixing into light of various colors. This light is reflected onto the inside of the transparent lampshade which transmits it to its outside producing the luminous areas of various forms and colors.

Claims

1. A colour effect light with several differently coloured illuminants whose brightness can be regulated separately, and with a three-dimensionally extending transparent lampshade, and with a three-dimensionally extending light mixing and reflecting body, comprising:

said light mixing and reflecting body having an effective three-dimensionally shaped outside-surface and is at least partially surrounded by said transparent lampshade,

said differently coloured illuminants are provided with directing means concentrating or focusing light of said differently coloured illuminants into respective light beams,

said differently coloured illuminants are spaced from one another, and adjusted to cast light beams from different positions on, and in direction to an effective outside-surface of said light mixing and reflecting body,

said differently coloured light is mixed additively on the effective outside-surface of said light mixing and reflecting body where different light beams meet one another, and

the light cast on the effective outside-surface of said mixing and reflecting body is reflected onto an inside of said transparent lampshade which transmits the reflected light outside where luminous areas of various forms and colours are effective.

2. The colour effect light according to claim 1, wherein said light-mixing and reflecting body is a cone and the lampshade is a cylinder whereby the cone standing on its apex is positioned concentrically in the cylinder and the illuminants are arranged in a circle around the apex of the cone and radiate onto the cone surface where the light is mixed additively and is reflected onto the inside of the cylindrical lampshade.

3. The colour effect light according to claim 1, wherein said cone is hollow and the cone surface is a white, transparent plastic film.

4. The colour effect light according to claim 1, wherein said light-mixing and reflecting body can be interchanged.

5. The coloured effect light according to claim 1, wherein said light mixing and reflecting body is partially transparent and gives way to some of the light passing through from one portion to another portion of its outside-surface where it emerges and may be mixed with light directly incident on this other portion.

6. The coloured effect light according to claim 1, wherein said light mixing and reflecting body is partially translucent and gives way to some of the light passing through from one portion to another portion of its outside-surface where it emerges and may be mixed with light directly incident on this other portion.
