Abstract

According to one embodiment, a reflector device is disclosed. In one example, the reflector device comprises a reflector having a plus-shaped cross section, and at least one solid state light emitting element. The reflector may comprise at least a first and a second surface portions, which extend in planes intersecting at an angle, said at least one solid state light emitting element being mounted to one of said first surface portion or said second surface portion.

First claim

The invention claimed is:

1. A reflector device comprising:
a reflector having four pairs of surface portions that constitute a plus-shaped cross section, wherein said surface portions are flat; and
at least one solid state light emitting element mounted to each pair of the surface portions;
wherein said at least one solid state light emitting element extends through a hole of the reflector, such that a light emitting portion of said at least one solid state light emitting element protrudes from one surface of each pair of the surface portions, while a support portion of said at least one solid state light emitting element is positioned at the other surface of each pair of the surface portions.

2. The reflector device according to claim 1 , wherein the reflector comprises four V-shaped grooves.

3. The reflector device according to claim 1 , wherein the at least one solid state light emitting element is being mounted to one surface portions of the pairs of the surface portions in an alternate configuration.

4. The reflector device according to claim 1 , wherein the angle of intersection is 90 deg.

5. The reflector device according to claim 1 , wherein each one of said first and second surface portions has a side edge, said at least one solid state light emitting element being mounted at a distance from the side edge of the surface portion at which it is mounted.

6. The reflector device according to claim 5 , wherein the side edge of said first and second surface portions is in contact with a transmissive light outlet.

7. A lighting device comprising a transmissive light outlet portion, and a reflector device according to claim 1 , wherein light is outlet from the lighting device through a light outlet portion.

8. The lighting device according to claim 7 , further comprising a light diffuser, which light diffuser is arranged to diffuse the light before being outlet from the lighting device.

9. The lighting device according to claim 8 , wherein the light diffuser comprises the light outlet portion, which is provided with light diffusing properties.

10. The lighting device according to claim 9 , comprising a tubular portion, which is elongated and which includes the light outlet portion.
