The invention relates to a reflector unit and a lighting device (1) having a plurality of light sources (4) and a reflection arrangement, with the light sources (4) being positioned in front of a reflection surface of the reflection arrangement, with the light beam from the light sources (4) being deflected by reflection to the main emission direction of the lighting device (1) via the reflection arrangement. According to the invention, a first reflection section (2) and a raised second reflection section (5) are provided, with the first and the second reflection sections being matched to one another such that a main light beam can be produced, in that the light from the light sources (4) first of all strikes the second reflection section (5), and then the first reflection section (2), and leaves the lighting device in the main emission direction.
In a lighting device (1) having a plurality of light sources (4) and a reflection arrangement, with the light sources (4) being positioned in front of a reflection surface of the reflection arrangement wherein the improvement comprises the plurality of light sources (4) arranged around an outlet opening (10) in the plurality of light sources, said plurality of light sources facing an opposing concave conical reflection section (2) having a raised convex conical reflection section (5) disposed internal with respect to the concave conical reflection section (2) and at least partially surrounded by the concave reflection section (2), with the concave conical and convex conical reflection sections being matched to one another and opposed to the plurality of light sources such that a main light beam emission is produced whereby light from the plurality of light sources (4) first strikes the raised convex conical reflection section (5) and is reflected from there onto the concave conical reflection section (2) and leaves the reflection arrangement in the a main emission direction through the outlet opening (10) in the plurality of light sources.
In a lighting device having a plurality of light sources and a reflection arrangement, with the light sources being positioned in front of a reflection surface of the reflection arrangement wherein the improvement comprises a light having an emission direction of a light beam in the same direction or in an opposite direction from the plurality of light sources wherein the reflection arrangement has a concave conical reflection section (2, 11) having a raised convex conical reflection section (5) disposed internal with respect to the concave conical reflection section (2) and at least partially surrounded by the concave conical reflection section (2), with the concave conical and convex conical reflection sections being matched to one another such that a main light beam is produced in which light from the plurality of light sources first strikes the concave conical reflection section (2, 11) and then the raised convex conical reflection section (5) and after reflection from the raised convex conical reflection section is emitted in the main emission direction of the lighting device.
In a reflector unit for a lighting device having a multiplicity of light sources (4) wherein the improvement comprises the multiplicity of light sources (4) arranged around a concave shaped ring and a reflection arrangement having at least two reflection sections where at least one reflection section is a raised convex reflection section having a raised conical reflection section which is internal with respect to a concave reflection section and is at least partially surrounded by the concave reflection section, with the at least two reflection sections both in front of and facing the multiplicity of light sources to produce a main light beam from the multiplicity of light sources so that light strikes and is reflected from the at least two reflection sections and leaves the reflection arrangement in a main emission direction through an outlet in the concave shaped ring or through an outlet in the raised conical reflection section.
