Embodiment Construction

[0044] figure 1 An oblique top view of a one-piece reflector 1 according to a first exemplary embodiment is shown. The reflector 1 can be produced, for example, by means of a plastic injection molding process. The reflector 1 has four cup-shaped or funnel-shaped reflector recesses 2 arranged rotationally symmetrically about a longitudinal axis L, the inner walls 3 of which are embodied reflectively or diffusely reflectively. The inner wall 3 can be shaped as a parabolic, hyperbolic or free-form surface. On the rear side of the reflector recess belonging to the reflector base 4 , the reflector recess 2 is each equipped with a central rear-side recess 6 . On the front side 7 of the reflector 1 , each of the reflector recesses 2 has a front-side reflector opening 8 .

[0045] Light emitted by a light source arranged below the recess enters through the corresponding rear-side recess 6 , or the light source can protrude into the recess 6 from behind or below. The light subseque...

Abstract

The invention relates to a reflector (1) for a lighting device (13), comprising at least one recess (6) on the rear side thereof for a light source (20) and at least one reflector opening (8) on the front side thereof, wherein at least one spring element (10) is integrated in the reflector (1). The lighting device (13) comprises at least one such reflector (1) wherein the at least one reflector opening (8) on the front side thereof is covered by means of a cover element (53) pressing on the reflector (1).

Description

technical field [0001] The invention relates to a reflector for a lighting device, which has at least one front reflector opening and at least one rear recess, respectively, for a light source. Background technique [0002] For installation in LED lamps, reflectors have hitherto typically been glued or fastened. The general problem here is that mechanical tolerances have to be compensated. Until now, this has been solved using one or more compensating elements, such as compression springs. [0003] DE 10 2004 004 778 A1 relates to a light-emitting diode lighting module having one or more light-emitting diode components and an optical system for beam shaping which is arranged downstream of the light-emitting diode components in their radiation direction. The optical arrangement has a radiation-focusing optical element for each light-emitting diode component, a radiation-expanding optical element being arranged downstream of said radiation-focusing optical element, viewed fr...
