Title:
LASER DIODES BASED ILLUMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/065978
Kind Code:
A3
Abstract:
An illumination device includes a bulb including a segment of at least second order curvature and a cylindrical segment. A least two laser diodes are coupled with the bulb such that laser beams emitted by the at least two laser diodes propagate inside the bulb through total internal reflection. The laser beams propagating in the bulb expand in the bulb, are evenly mixed and exceed outward from the bulb as a volumetric light flux.
