Abstract

The invention relates to a lighting device (1) comprising a plurality of light sources which are capable of emitting light towards a surface (S). The lighting device is arranged in such a way that light from at least one first light source (2) forms a first lighting pattern (I) of white light on said surface and light from a plurality of second light sources (3) forms a second lighting pattern (II) of light of a different color on said surface. The second lighting pattern substantially surrounds said first white lighting pattern.

Claims

1. A lighting device comprising a plurality of light sources capable of emitting light towards a surface (S), wherein said lighting device is arranged in such a way that the light from at least one first light source forms a first lighting pattern of white light on said surface and the light from a plurality of second light sources forms a second lighting pattern of colored light on said surface, such that said second lighting pattern substantially surrounds said first lighting pattern.

2. The lighting device according to claim 1, wherein said at least one first light source is at least partially surrounded by said plurality of second light sources.

3. The lighting device according to claim 1, wherein said lighting device comprises a first controller for selectively controlling at least one of said first and second light sources for adjusting at least parameter of at least one of said first and second lighting patterns.

4. The lighting device according to claim 1, wherein said lighting device comprises a first controller for selectively controlling at least one second light source to form one or more third lighting patterns varying in position relative to said second lighting pattern.

5. The lighting device according to claim 1, wherein said lighting device further comprises at least one optical element for controlling the light emitted from at least one of said first and second light sources and a second controller arranged to control said optical element for adjusting at least one parameter of said first and second lighting patterns.

6. The lighting device according to claim 1, wherein said lighting device further comprises at least one diaphragm for defining a contour of at least one of said first and second lighting patterns.

7. The lighting device according to claim 1, wherein said first and second light sources are selected from the group consisting of:

incandescent lamps, halogen lamps, LEDs and high-intensity discharge lamps.
