Definitions
- the invention relates to a color effect lamp that generates light of all colors.
- the principle of light generation is based on the principle of "additive color mixing", which is known per se.
- additive color mixing which is known per se.
- the three primary colors red, green and blue are projected one above the other and, depending on the intensity of the individual colors, result in all colors of the rainbow, including white.
- the present invention is concerned with the use of this principle for use in a color effect lamp.
- a lampshade is largely determined by aesthetic considerations.
- a lampshade designed from an aesthetic point of view generally does not have the geometry required for producing the color effect. Because the outer, the visible shape of the lampshade usually takes precedence before the functionality, ie for the generation of color effects, only such color effects with little variability can be achieved with such lamp arrangements.
- a lamp has several differently colored lamps and a lampshade.
- a light mixing and reflection body is arranged within the lampshade and is illuminated by the lamps.
- the light mixing and reflection body is e.g. B. a cone made of optically clear plastic.
- the surface is matted.
- the cone can also be hollow. When light of different colors hits the surface of the cone from different directions, an additive color mixture occurs on the surface. Part of the light can also penetrate the cone and exit on the opposite side. On this side, the incident light mixes with the emerging light, which also leads to color effects.
- the shape of the light mixing and reflection body can be arbitrary and influences the shape and the color effects on the lampshade. The only thing that matters is that an additive color mixture is generated on the surface of the light mixing and reflection body and this mixed light is emitted onto the lampshade.
- the brightness of the illuminants can be regulated to produce a wide variety of lighting effects, and even white light can be generated.
- the Lichtmisch- and reflection body opaque, for. B. matt white.
- the additive light mixing takes place only on the surface section of the light mixing and reflection body, which is directly irradiated by the respective illuminants.
- the mixed light is emitted from this surface section onto the inner surface of the lampshade and appears there as a colored light spot. If the color components are evenly distributed, a white light spot appears.
- the light mixing and reflection body is translucent and has a surface that is suitable for additive light mixing. That can e.g. B. a glass body with a matt surface. Part of the incident light is mixed on this matted surface and emitted as mixed light on the inside of the lampshade. The other part of the light emitted by the colored light sources penetrates the glass body and hits the matt surface from the inside on the opposite side of the glass body, where an additive color mixture also occurs. This mixed light is also emitted on the inside of the lampshade.
- the person skilled in the art can produce a wide variety of light mixing and color effects through the design of the shape and the surfaces of the color mixing and reflection body, especially its translucency and surface structure.
- the light mixing and reflection body is designed as a cone and the lampshade as a cylinder.
- the cone is on the tip and is arranged concentrically in the cylinder.
- the lamps are arranged in a circle around the cone tip and shine on the cone shell, where the light is mixed additively and emitted onto the inside of the cylindrical lampshade.
- the cone is hollow and the cone jacket made of a white, translucent plastic film.
- This embodiment is particularly suitable for cost-effective production in large quantities.
- the light mixing and reflection body is interchangeable. This measure is also suitable for cost-effective production in large quantities.
- Fig. 1 shows a schematic representation of the invention in side view.
- Fig. 2 shows the schematic diagram of Fig. 1 in plan view.
- Fig. 1 shows a color effect lamp with illuminants 1, 2 and 3, which are arranged in a star shape and pivoted so that their light cones can be adjusted.
- the illuminants 1, 2, 3 are arranged on the lower end section of a cylindrical lampshade 4 and shine obliquely upwards onto a conical light mixing and reflection body 5.
- the illuminants can each have a color filter V, 2 'and 3' or have colored glass flasks.
- the light rays emanating from the illuminants 1 and 2 meet on the surface of the conical light-mixing and reflection body 5 at point 6.
- the mixed light which is produced there is emitted and strikes the inside of the cylindrical lampshade 4 at point 7, which from the outside as colored light spot appears.
