LASER LIGHTING SYSTEM COMPRISING OPTICAL FIBER

Abstract

The invention provides a light generating system comprising a light generating device, an optical fiber, and a light generating unit. Especially, the light generating device may be configured to generate device light comprising a first wavelength, wherein the light generating device comprises a solid-state light source. Especially, the optical fiber may comprise an elongated body of light transmissive material, transmissive for the device light comprising the first wavelength. Further, the optical fiber may comprise a light entrance part. Especially, the optical fiber may have a length L1 and an elongated outer surface over at least part of its length L1. Especially, the optical fiber may be configured such that upon irradiating the light entrance part with the device light comprising the first wavelength, over at least part of its length L1 second light escapes from the optical fiber via the elongated outer surface. Further, the light generating unit may comprise a light chamber. Especially, the light chamber may comprise a reflective internal surface, reflective for the second light, and a chamber exit window, transmissive for the second light. Further, at least part of the optical fiber having a chamber fiber length L2 may be configured within the light chamber with n1 curvatures in a plane parallel to a length axis (A) of the optical fiber (500), wherein n1=1. Especially, the light generating system may be configured to generate system light comprising at least part of the second light escaped from the light chamber via the chamber exit window.
