Claim Text:
1. A lighting apparatus comprising: laser light modification units configured to modify laser light to modified light, wherein a first laser light modification unit of the laser light modification units comprises a first luminescent material for emitting a first luminescent light and a second laser light modification unit of the laser light modification units comprises a second luminescent material for emitting a second luminescent light, the first luminescent light and the second luminescent light being the modified light when illuminated by the laser light; a laser for emitting the laser light that is to be directed along a longitudinal axis of the lighting apparatus to the first and second luminescent material of the laser light modification units; a first layer and an opposing second layer; and an intermediate transparent layer disposed between the first layer and the second layer, wherein the laser light modification units are arranged between the first layer and the second layer, wherein at least one of the first layer and the second layer comprises a transparent material being transparent to the modified light, wherein the laser light modification units are configured to allow the modified light to pass through the transparent material, said laser light modification units being arranged at different locations between the first layer and the second layer, wherein only the first luminescent material and the second luminescent material protrude in a transverse direction transverse to the laser light and to the longitudinal axis of the lighting apparatus, and wherein a first protruding length of the first luminescent material is different from a second protruding length of the second luminescent material, the first protruding length and the second protruding length being a length of protrusion into the laser light along the transverse direction of the laser light, and wherein the laser and the first and second luminescent material of the laser light modification units are arranged such that the laser light modification units are simultaneously illuminatable by the laser light, and wherein the intermediate transparent layer comprises one of gas and liquid.
