Abstract

A reflector ( 1; 31; 41 ) for a lighting device comprising: ( 13; 61; 62 ), at least one rear cutout ( 6 ) for a light source ( 20; 47; 56 ) in each case and at least one front-side reflector opening ( 8 ), wherein at least one spring element ( 10; 34; 45 ) is incorporated into the reflector ( 1; 31; 41 ).

First claim

The invention claimed is:

1. A reflector for a plurality of lighting devices, comprising:
a reflector holder having a plurality of conical-shaped reflective surfaces disposed in an axially symmetric manner about a longitudinal axis, each conical-shaped reflective surface having a front-side reflector opening at a wider end of the conical-shaped reflective surface, and a rear cutout at a narrower end of the conical-shaped reflective surface, the rear cutout shaped for mounting one of the plurality of lighting devices therein so that light from the lighting device radiates directly or indirectly toward the front-side reflector opening, the reflector holder having a front-side surface in which the front-side reflector openings are positioned;
a covering element configured to cover the front-side surface of the reflector holder so that the plurality of front-side reflector openings are covered by the covering element;
a light source carrier onto which each of the plurality of lighting devices is mountable;
a housing;
at least one elastic spring element integrally formed along a circumferential periphery of an upper edge of the reflector holder, the upper edge being at a front side of the reflector holder where light radiates from the plurality of conical-shaped reflective surfaces through the plurality of front-side reflector openings, each spring element having a shape of

a connected double U with each U being positioned alongside another U with the openings of the connected double U directed toward the upper edge of the reflector and a width of the connected double U being oriented to extend partially around the circumferential periphery of the upper edge of the reflector holder; and
a locking mechanism,
wherein the covering element is disposed on the reflector holder, the reflector holder is disposed on the light source carrier, and the light source carrier is disposed on the housing so as to form an enclosed space delimited by the covering element and the housing,
wherein each spring element is configured so that a portion of each spring element projects forward beyond the front-side surface of the reflector holder so that each spring element presses against the covering element, and
wherein the locking mechanism in configured to lock the covering element to the housing.

2. The reflector of claim 1 , wherein the reflector holder is of at least two-piece design with the plurality of conical-shaped reflective surfaces being separate inserts mounted into the reflector holder.

3. The reflector of claim 1 , wherein the reflector holder is of one-piece design with the plurality of conical-shaped reflective surfaces being formed into the reflector holder.

4. The reflector of claim 1 , wherein the reflector holder has at least one rearward projecting spacer seated on the light source carrier.

5. A reflector for a plurality of lighting devices, comprising:
a reflector holder having a plurality of conical-shaped reflective surfaces disposed in an axially symmetric manner about a longitudinal axis, each conical-shaped reflective surface having a front-side reflector opening at a wider end of the conical-shaped reflective surface, and a rear cutout at a narrower end of the conical-shaped reflective surface, the rear cutout shaped for mounting one of the plurality of lighting devices therein so that light from the lighting device radiates directly or indirectly toward the front-side reflector opening, the reflector holder having a front-side surface in which the front-side reflector openings are positioned;
a covering element configured to cover the front-side surface of the reflector holder so that the plurality of front-side reflector openings are covered by the covering element;
a light source carrier onto which each of the plurality of lighting devices is mountable;
a housing;
at least one elastic spring element integrally formed along a circumferential periphery of an upper edge of the reflector holder and extending radially outward from the longitudinal axis, the upper edge being at a front side of the reflector holder where light radiates from the plurality of conical-shaped reflective surfaces through the plurality of front-side reflector openings, each spring element comprising an obliquely forward facing, unilaterally fixed bar, a portion of each spring element projecting forward beyond and through the front-side surface of the reflector holder; and
a locking mechanism,
wherein the covering element is disposed on the reflector holder, the reflector holder is disposed on the light source carrier, and the light source carrier is disposed on the housing so as to form an enclosed space delimited by the covering element and the housing,
wherein each spring element is configured so that each spring element presses against the covering element, and
wherein the locking mechanism is configured to lock the covering element to the housing.

6. A reflector for a plurality of lighting devices, comprising:
a reflector holder having a plurality of conical-shaped reflective surfaces disposed in an axially symmetric manner about a longitudinal axis, each conical-shaped reflective surface having a front-side reflector opening at a wider end of the conical-shaped reflective surface, and a rear cutout at a narrower end of the conical-shaped reflective surface, the rear cutout shaped for mounting one of the plurality of lighting devices therein so that light from the lighting device radiates directly or indirectly toward the front-side reflector opening, the reflector holder having a front-side surface in which the front-side reflector openings are positioned;
a covering element configured to cover the front-side surface of the reflector holder so that the plurality of front-side reflector openings are covered by the covering element;
a light source carrier onto which each of the plurality of lighting devices is mountable;
a housing;
at least one elastic spring element integrally formed along a circumferential periphery of an upper edge of the reflector holder, the upper edge being at the front-side surface of the reflector holder where light radiates from the plurality of conical-shaped reflective surfaces through the plurality of front-side reflector openings, each spring element having a shape of a single U with an opening of the U directed toward the upper edge of the reflector and a width of each U being oriented to extend partially around the circumferential periphery of the upper edge of the reflector holder; and
a locking mechanism,
wherein the covering element is disposed on the reflector holder, the reflector holder is disposed on the light source carrier, and the light source carrier is disposed on the housing so as to form an enclosed space delimited by the covering element and the housing,
wherein each spring element is configured so that each spring element causes the reflector holder to press against the covering element, and
wherein the locking mechanism is configured to lock the covering element to the housing.

7. The reflector of claim 6 , wherein the reflector holder has a support element and each spring element is incorporated into a respective support element of the reflector, and wherein the respective support element is disposed on the housing.
