Lighting device
First Claim
1. A lighting device comprising at least one light source as well as a light reflector disposed beside the light source for reflection of at least part of the light radiated from the light source, characterized in that the light reflector comprises at least one light-transmitting element bounding a space at least in part, as well as a diffusely reflective powder present inside said space.

Abstract
A lighting device (1) comprising at least one light source (3) as well as a light reflector disposed beside the light source (3) for reflection of at least part of the light radiated from the light source (3), a special feature being the fact that the light reflector comprises at least one light-transmitting element (4) bounding a space (5) at least in part, as well as a diffusely reflective powder (6) present inside said space (5).

15. A method for manufacturing a lighting device, in which at least one light source and at least one lighting fixture are supplied and in which a light reflector is arranged beside the light source for diffuse reflection of at least part of light radiated from the light source and for specular reflection of at least another part of the light radiated from the light source so as to increase light output of the lighting device and to restrict the angular distribution of the intensity of the emitted light beam from the lighting device, characterized in that at least one light-transmitting element bounding a space at least in part, as well as a diffusely reflective powder present inside said space are used as the light reflector, wherein the light-transmitting element comprises at least two substantially parallel, substantially optically smooth surfaces, and wherein the surface of the light-transmitting element that faces towards the light source extends substantially parallel to the surface of the lighting fixture facing the lamp.
