The phosphor (105,113) is thermally connected to a heatsink (103,116), of example by a plate (114) of sapphire glass, so as to dissipate the heat produced by the phosphor (105,113). The phosphor (105) may be mounted on a plane reflector (104) disposed on or comprising the heatsink (103) and facing a curved reflector (102) and the radiation source.

    Abstract: A laser beam (L50) generated by a laser light source (50) is reflected by a light beam scanning device (60), and irradiated onto a hologram recording medium (45). On the hologram recording medium (45), an image (35) of a scatter plate is recorded as a hologram by using reference light that converges on a scanning origin (B). The light beam scanning device (60) bends the laser beam (L50) at the scanning origin (B) and irradiates it onto the hologram recording medium (45). At this time, scanning is carried out by changing the bending mode of the laser beam with time so that the irradiation position of the bent laser beam (L60) on the hologram recording medium (45) changes with time. Regardless of the beam irradiation position, diffracted light (L45) from the hologram recording medium (45) reproduces the same reproduction image (35) of the scatter plate at the same position.

  • Patent number: 8844189
    Abstract: A sighting device replicates the spread pattern of pellets exiting the barrel of a shotgun. The sighting device includes a light source (preferably a laser) and a power source connectable to the light source. The device may also include a mount to attach the sighting device to a shotgun. The sighting device preferably projects a circular pattern of individual light beams wherein the circumference of the circular pattern increases as the light beams move farther from the sighting device to replicate the spread of shotgun pellets. The sighting device may also project a beam of light in the center of the pattern.

  • Patent number: 8820968
    Abstract: A method of manufacturing a wavelength conversion element can control a formation process of a polarization inversion structure with single crystalline magnesium-doped lithium niobate having a congruent composition, and can stably manufacture wavelength conversion elements having high conversion efficiency. The method involves forming periodic electrodes on the +z face of an MgLN substrate and forming an opposite electrode on the ?z face of the MgLN substrate; heat-treating the substrate after forming the periodic electrodes and the opposite electrode; and applying a pulsed electric field between the periodic electrodes and the opposite electrode while holding the MgLN substrate at a temperature of 100° C. or higher. The wavelength conversion element has a polarization inversion structure formed by applying an electric field to a heat-treated MgLN substrate.

  • Patent number: 8820967
    Abstract: The invention relates to a lighting apparatus comprising a laser (102) for emitting a first laser beam (103) and a diffractive reflective element (104). The first laser beam (103) is reflected by the diffractive reflective element (104) for generating a second laser beam (105) being the reflected first laser beam, wherein the diffractive reflective element (104) is adapted such that the effective surface area of the second laser beam (105) is larger than the effective surface area of the first laser beam (103). The second laser beam is supposed to be pointed directly or indirectly to the eyes of a person. Since the diffractive reflective element increases the effective surface area and is used in a reflective mode, i.e. the first laser beam will generally not directly meet the eye of the person, if the diffractive reflective element is damaged or displaced, the risk of eye damages can be reduced.

  • Patent number: 8794801
    Abstract: One embodiment relates to an oblique illuminator. The oblique illuminator includes a light source emitting a light beam, a first reflective surface, and a second reflective surface. The first reflective surface has a convex cylindrical shape with a projected parabolic profile along the non-powered direction which is configured to reflect the light beam from the light source and which defines a focal line. The second reflective surface has a concave cylindrical shape with a projected elliptical profile which is configured to reflect the light beam from the first reflective surface and which defines first and second focal lines. The focal line of the first reflective surface is coincident with the first focal line of the second reflective surface. The first and second focal lines of the second reflective surface may be a same line in which case the elliptical curvature is a projected spherical profile. Other embodiments, aspects and features are also disclosed.
