摘要:
In a light source device, a control unit causes an energy density of a laser light in a lighting start region RS when a laser support light is maintained to be lower than an energy density of the laser light in the lighting start region RS when the laser support light is put on. For this reason, when the laser support light is maintained, a laser light L is radiated to the lighting start region RS at an energy density of a degree where sputtering does not occur. Therefore, in the light source device, because sputtering in a light emission sealing body can be suppressed, a sufficiently long life can be realized.

An ignition facilitated electrodeless sealed high intensity illumination device is disclosed. The device is configured to receive a laser beam from a continuous wave (CW) laser light source. A sealed chamber is configured to contain an ionizable medium. The chamber has an ingress window disposed within a wall of a chamber interior surface configured to admit the laser beam into the chamber, a plasma sustaining region, and a high intensity light egress window configured to emit high intensity light from the chamber. A path of the CW laser beam from the laser light source through the ingress window to a focal region within the chamber is direct. The ingress window is configured to focus the laser beam to within a predetermined volume, and the plasma is configured to be ignited by the CW laser beam, optionally by heating of a non-electrode ignition agent located entirely within the chamber.

A light-extraction apparatus for an optical-film lighting set having a visible-light coating include a transparent sealed body, a wide AOR (0 degree to 90 degrees) optical film for reflecting ultraviolet lights and a visible light layer. The transparent sealed body is formed as a hollow shell body to accommodate an ultraviolet light source. A supporting member coated with the optical film and the visible light layer is constructed to a wall of the shell body or inside the shell body. The visible light layer is consisted of monolayered fluorescent or phosphorescent particles, and the particles are evenly distributed to coat on the interior wall of the shell body or the supporting member inside the shell body in a sparse scattering manner. A fixed area ratio of the coverage of the particles to that of the inter-particle spacing is then provided to the visible light layer for obtaining a higher illumination performance.

The invention relates to light sources with laser pumping and to methods for generating radiation with a high luminance in the ultraviolet (UV) and visible spectral ranges. The technical result of the invention includes extending the functional possibilities of a light source with laser pumping by virtue of increasing the luminance, increasing the coefficient of absorption of the laser radiation by a plasma, and significantly reducing the numerical aperture of a divergent laser beam which is to be occluded and which is passing through the plasma. The device comprises a chamber containing a gas, a laser producing a laser beam, an optical element, a region of radiating plasma produced in the chamber by the focused laser beam, an occluder, which is mounted on the axis of the divergent laser beam on the second side of the chamber and an optical system for collecting plasma radiation.
