Abstract:
A lighting device (1) comprising a light generating element (2; 3), and a micro-lens (4) comprising a focal plane (Fp), wherein the light generating element (2; 3) comprises a first light generating component (2) and a second light generating component (3), wherein the first light generating component (2) comprises a light emitting surface (28) adapted for providing a diffuse light output component, wherein the second light generating component (3) comprises at least one array of light sources (3) adapted for providing a directional light output component, wherein the light generating element (2; 3) is arranged to emit a light output towards the micro-lens array (4), the light output being formed by a superposition of the diffuse light output component and the directional light N output component, and wherein the array of the light sources (3) is located in the focal plane (Fp) of the micro-lens array (4).
