Lighting arrangement

1. A lighting system comprising:

a laser light source;

a scanning mirror arranged to rotate around two substantially orthogonal axes, the scanning mirror to receive light radiated by the laser light source and to reflect the received light;

a wavelength conversion element to receive the light reflected by the scanning mirror and to emit multi-spectral light; and

a reflector element non-coupled to and spatially separate from the wavelength conversion element, the reflector element comprising:

an array of a plurality of micro-focal elements to receive the multi-spectral light emitted from the wavelength conversion element and to converge or diverge the received multi-spectral light, wherein the array comprises at least one first micro-focal element having a first concave shape and at least one second micro-focal element having a second convex shape; and

a reflective surface to reflect the converged or diverged multi-spectral light towards an exit aperture.

2. The lighting system according to claim 1 , wherein the laser light source is located on a first side of the wavelength conversion element, where the reflected light is arranged to exit the lighting system, and the reflector element is located on a second side of the wavelength conversion element, the second side being opposite to the first side.

3. The lighting system according to claim 1 , wherein the plurality of micro-focal elements are microlenses or micro-reflectors.

4. The lighting system according to claim 1 , wherein the plurality of micro-focal elements have a maximum dimension between 1 micrometers and 5 millimeters.

5. The lighting system according to claim 1 , wherein the array comprises between 10,000 and 2,250,000 micro-focal elements.

6. The lighting system according to claim 1 , wherein the array comprises micro-focal elements of at least two different types.

7. The lighting system according to claim 6 , wherein one type of micro-focal element is defined by at least one of a focal length, or a size.

8. The lighting system according to claim 1 , wherein the second convex shape of the micro-focal elements corresponds to a spherical shape.

9. The lighting system according to claim 1 , wherein the first concave shape of the micro-focal elements corresponds to a cylindrical shape.

10. The lighting system according to claim 1 , wherein at least one of the first shape or the second shape of the micro-focal elements corresponds to an aspherical shape.

11. The lighting system according to claim 1 , wherein the light reflected from the reflector element is arranged to pass through the wavelength conversion element towards the exit aperture.

12. The lighting system according to claim 1 , wherein the reflector element is oriented so that the light reflected from the reflector element exits the lighting system without being further reflected.

13. The lighting system according to claim 1 , wherein the wavelength conversion element comprises a phosphorous layer.

14. A method, comprising:

radiating light to a scanning mirror arrangement arranged to be rotatable around two substantially orthogonal axes;

reflecting the radiated light to a wavelength conversion element;

re-emitting, from the wavelength conversion element, broad-spectral light;

converging or diverging, at an array of a plurality of micro-focal elements, the broad-spectral light re-emitted by the wavelength conversion element,

wherein the array comprises at least one first micro-focal element having a first concave shape and at least one second micro-focal element having a second convex shape; and

reflecting the converged or diverged light towards an exit aperture of a lighting system by a reflector element physically non-coupled to and spatially separate from the wavelength conversion element.
