Abstract:
The invention provides a lighting device comprising a first luminescent concentrator further using a second luminescent material of another composition alongside the first luminescent concentrator (especially no optical contact and/or optically separated using a dichroic mirror). Especially, this second material has an absorption band overlapping with the emission band of the first material. As a consequence a significant part of the light generated by the first luminescent material will be absorbed by the second material resulting in a high brightness white source with increased efficiency.

Claim (Index 1):
A lighting device comprising:\n a plurality of luminescent concentrators, each luminescent concentrator comprising an elongated light transmissive body having a first face and a second face defining a length of the elongated body, the elongated body comprising one or more side edges, wherein one or more side edges comprise one or more radiation input faces wherein the second face comprises a radiation exit window; each elongated light transmissive body comprising a luminescent material configured to convert at least part of a pump radiation received at one or more radiation input faces into luminescent material light, and each luminescent concentrator, configured to couple at least part of the luminescent material light out at the radiation exit window as converter light; a plurality of light sources configured to provide light source radiation as first pump radiation to the one or more radiation input faces of a first luminescent concentrator; said first luminescent concentrator comprising a first luminescent material configured to convert at least part of the first pump radiation into first luminescent material light, and configured to couple at least part of the first luminescent material light out at the first radiation exit window as first converter light; a second luminescent concentrator configured parallel to the first luminescent concentrator with a side edge of the first luminescent concentrator configured parallel to a side edge of the second luminescent concentrator, wherein the second luminescent concentrator is configured to receive at said side edge of the second luminescent concentrator one or more of said first pump radiation and said first luminescent material light escaping from said side edge of said first luminescent concentrator as second pump radiation, the second luminescent concentrator comprising a second luminescent material configured to convert at least part of the second pump radiation into second luminescent material light, and configured to couple at least part of the second luminescent material light out at the second radiation exit window as second converter light; wherein one or more of the luminescent concentrators are longer than one or more of the other luminescent concentrators, thereby providing one or more luminescent concentrator extending parts extending relative to the one or more other luminescent concentrators, and wherein a subset of one or more light sources is configured to provide light source radiation to the one or more luminescent concentrator extending parts.
