Abstract

A lighting system comprising a track having a first and a second rail ( 5, 7 ), mutually extending equidistantly. Said first and second rail comprise a first respectively a second electrically conductive strip ( 13, 15 ), mutually electrically isolated. A lighting module comprising a first and second electrical contact, which lighting module in mounted position rests by gravitational force on the first and second rail. When mounted the first and second electrical contact are in electrical contact with a respective one of the first and second electrically conductive strip. The lighting module is dismountable from the track by a single displacement of the lighting module in a direction against the direction of the gravitational force.

First claim

The invention claimed is:

1. A lighting system accommodating a light source and further comprising:
a track comprising at least a first and a second rail mutually extending equidistantly along a length axis, said first and second rail are spaced apart by an opening defining a plane P and the first rail comprises a first electrically conductive strip and the second rails comprises a second electrically conductive strip, said strips are mutually electrically isolated, each rail has a ridge extending perpendicular to the plane P,
at least one lighting module comprising a first and second electrical contact adapted to make electrical contact with a respective one of the first and second electrically conductive strip when supported by a respective carrier side of both the first and the second rail, and comprising a base having a mutually opposing first and second side,
the lighting module and track being free from mutual overhang to allow for an integration of the lighting module into the track rather than hanging the lighting module underneath the track and to enable to dismount the lighting module from the track by a displacement of the lighting module in a direction essentially perpendicular to the plane P,
the lighting module is provided with grooves that, in mounted position, grip around at least a part of a respective rail, and the grooves are present on both the first and second side of the lighting module to enable to flip the lighting module 180° over a horizontal axis.

2. The Lighting system as claimed in claim 1 , wherein the lighting module is passable through the plane P via said opening.

3. The Lighting system as claimed in claim 1 , wherein the lighting module is essentially planar and/or that the first side of the lighting module is essentially flush with the first and second rail.

4. The Lighting system as claimed in claim 1 , wherein the first and second electrical contact are provided at the first side of the lighting module and, the first and second electrically conductive strips are provided at the carrier side of the first respectively the second rail.

5. The Lighting system as claimed in claim 1 , wherein first and second electrical contact are provided at a side face extending from the first side towards the second side and that the first and second electrically conductive strips are provided on the rail at a respective rail wall extending from the carrier side normal to the plane P along the length axis.

6. The Lighting system as claimed in claim 1 , wherein the electrical contacts comprise a resilient part.

7. The Lighting system as claimed in claim 1 , wherein the rail has a cross section profile chosen from the group consisting of a U-profile, L-profile, concave curvature towards the lighting module, wedge-shape in a combination of the first and second strip.

8. The Lighting system as claimed in claim 1 , wherein the first and second rail are mutually axially aligned and together are shaped as a wedge extending along the length axis as a consecutive connected sequence of insets.

9. The Lighting system as claimed in claim 1 , wherein the lighting module is chosen from the group consisting of a power supply, a voltage power converter, a current source, a coupling module for coupling two lighting systems, and a user interactive receiver plus control module.

10. The Lighting system as claimed in claim 1 , wherein said anode and cathode are conductive strips extending along the length of the rails, preferably located on a respective rail wall extending from the carrier side normal to the plane P along the length axis.

11. The Lighting system as claimed in claim 1 , wherein the track has an elongated shape along the length axis, the lighting module being freely shiftable over said track along the length axis.

12. The Lighting system as claimed in claim 1 , wherein the rails are embodied as heat sinks to dissipate heat generated by the lighting module.

13. The Lighting system as claimed in claim 1 , wherein the lighting module is provided with an anti-collision system.

14. The Lighting system as claimed in claim 1 , wherein the lighting module is provided with rotatable wheels, preferably activated by a motor, to enable the lighting module to ride over the rails of said track along the length axis.

15. A Track being for use in the lighting system as claimed in claim 1 comprising at least a first and a second rail mutually extending equidistantly along a length axis, said first and second rail are spaced apart by an opening defining a plane P, each rail has a U-shaped profile in cross section with two legs of the U-shaped profile extending in a direction against gravity perpendicular to the plane P, the first rail comprises a first electrically conductive strip and the second rails comprises a second electrically conductive strip, said strips are provided at a respective rail wall extending from a carrier side of the rail normal to the plane P along the length axis and are mutually electrically isolated, the carrier of the rail extending in or along the plane P.

16. A Lighting module for use in the lighting system as claimed in claim 1 comprising a first and second electrical contact adapted to make electrical contact with a respective one of the first and second electrically conductive strip when supported by a respective carrier side of both the first and second rail, and comprising a base having a mutually opposing first and second side and wherein the lighting module comprises and the lighting module is provided with grooves, the grooves have a gripping function for a carrier and are present on both the first and second side of the lighting module to enable to flip the lighting module 180° over a horizontal axis and yet maintain said gripping function for said carrier.
