Abstract
A lighting device (1) comprising a light generating element (2; 3), and a micro-lens array (4) comprising a focal plane (Fp), wherein the light generating element (2; 3) is arranged to emit a light output towards the micro-lens array (4), wherein the lighting device (1) comprises an array of micro-logos (81-83), and wherein the array of micro-logos (81-83) is located in the focal plane (Fp) of the micro-lens array (4).
Claims14
A lighting device comprising:
- a light generating element, and
- a micro-lens array comprising a focal plane (Fp),
- wherein the light generating element is arranged to emit a light output towards the micro-lens array,
- wherein the light generating element comprises any one of or both of a first light generating component and a second light generating component,
- wherein the first light generating component comprises a light emitting surface adapted for providing a diffuse light output component,
- wherein the second light generating component comprises at least one array of light sources adapted for providing a directional light output component,
- wherein the light output is formed by any one of the diffuse light output component, the directional light output component and a superposition of the diffuse light output component and the directional light output component, respectively,
- wherein the lighting device further comprises an array of micro-logos located between the light generating element and the micro-lens array,
- wherein the array of micro-logos is located in the focal plane (Fp) of the micro-lens array, and
- wherein the at least one array of light sources comprises the array of micro-logos.
