摘要:
Intrinsically safe laser sourced illumination. A system for illumination is disclosed, including a plurality of laser illumination sources configured to transmit laser beams; a dichroic mirror spaced from the plurality of laser illumination sources and having an aperture configured to allow the laser beams to pass through the dichroic mirror, the remaining surfaces of the dichroic mirror configured to reflect the laser beams; a phosphor element spaced from the dichroic mirror and coated with a substance to fluoresce when struck by the laser beams and configured to disperse the laser beams and to output combined light that includes fluorescent light and the dispersed laser beams; and an illumination output arranged to receive the combined light from the phosphor element and to output illuminating light containing both the fluorescent light and the dispersed laser beams. Methods are also disclosed.
