  • Patent number: 10724692
    Abstract: A light source unit includes a light distribution lens configured to guide light emitted from an LED disposed behind the light distribution lens, and a reflector arranged to surround the light distribution lens. Illuminance unevenness can be more suitably reduced, and effective light is not blocked even if a pinhole device is used for glare prevention, thereby avoiding illuminance unevenness and illuminance reductions. The light distribution lens has a columnar part that extends in the optical axis direction, and a conical recess is formed in the distal end of the columnar part. The conical recess is constituted by a reflective surface that fully reflects, in the circumferential direction, light incident on the light distribution lens. The reflector reflects light emitted from a cylindrical side surface of the columnar part such that the reflected light becomes converging light.

    Abstract: An illumination apparatus, which is to be connected to a light source apparatus that generates laser light and which is to be attached to an optical cable that guides the laser light, is provided. The illumination apparatus includes a light-emitting module which is to be attached to a tip portion of the optical cable. The light-emitting module receives the laser light emitted from the optical cable, converts the laser light into light having a different wavelength of a predetermined color, and emits the light. A heat dissipating lens case includes a lens and dissipates heat generated by the light-emitting module. The lens controls distribution of the light emitted by the light-emitting module. The heat dissipating lens case includes an attachment structure which allows the heat dissipating lens case to be removably attached to the light-emitting module.

  • Patent number: 8094258
    Abstract: In a backlight apparatus, laminated optical sheets are housed in a tray such that a wall portion thereof surrounds their circumferences so that the optical sheets receive light from fluorescent lights. Tips of one corner portion A of optical sheets preferably have a shape in which the tips are trimmed by line segments extending between two edges defining the corner portions. At the wall portion of the tray, an opposing surface is formed along the line segments of the corner portions so as to correspond to the shape of the corner portions having tips trimmed off. The opposing surface restrains the line segments.

  • Patent number: 8075162
    Abstract: A zoomable luminaire has a source of light, a primary reflector with entry and exit apertures, and at least one secondary reflector with entry and exit apertures. The source delivers light into the entry aperture of the primary reflector, and the primary reflector delivers the light at the exit aperture of the primary reflector. The luminaire has a retracted position for producing a beam of a first beam angle, where the primary reflector is nested within the secondary reflector and the secondary reflector does not substantially affect the distribution of the light. The luminaire has at least one extended position for producing a beam of a second width, where the exit aperture of the primary reflector is contiguous with the entry aperture of a secondary reflector so that the light is delivered at the exit aperture of a secondary reflector.

  • Patent number: 8038327
    Abstract: A luminaire housing designed to be installed to illuminate an illumination area, wherein a light source is oriented within the housing to direct a central axis of emitted light rays away from the illumination area and towards a reflective surface of a stationary reflector. In some embodiments the stationary reflector is oriented and contoured to reflect the light rays towards a light passageway. In some embodiments, an adjustable reflector is also provided that is movable between at least a first and a second position. Optionally, the luminaire housing may be a recessed luminaire housing.

  • Patent number: 8033673
    Abstract: A light source (110) is fixed at a position and emits light in a direction away from an optical axis (A) of an objective lens. An outer reflecting mirror (an optical member) (130) and an inner reflecting mirror (an optical member) (140) are provided as a unit so that relative positions thereof are fixed. A reflecting mirror unit (120) can be moved in directions along the optical axis (A), i.e. up and down relative to the light source (110). A free-form curved surface portion (131) of the outer reflecting mirror (130) and a reflecting surface of the inner reflecting mirror (140) reflect light in different directions depending on a position of the light incident thereon.

  • Patent number: 7905630
    Abstract: A light effect system includes a light source and at least one aperture element interposed between the light source and an exit lens of the system. The aperture element has at least one aperture and at least one light effect element positioned therein. The system uses an aperture element having at least two “fingers” partly surrounding each light effect element in at least 180° of the circumference. These “fingers” engage with the contour of the outer surface of the light effect element to hold the light effect element in position in the aperture, and the fingers are formed of a flexible material. Hereby, it is achieved that the locking and releasing of the light effect component can be done by push and pull in an ideal perpendicular direction to the light path. In other words, no angling, bending or twisting is necessary, so a minimum of space is required.

  • Patent number: 7845834
    Abstract: The present invention discloses a lighting system with an adjustable illuminated area. The lighting system comprises a light source for outputting a light, a first refractive optical element and a second refractive optical element. The first and second refractive optical elements have continuous curvature. The first refractive optical element is movable along a first direction, while the second refractive optical element is movable along a second direction. The light passes through the first refractive optical element and the second refractive optical element to form an illuminated area. The shape and the size of the illuminated area are adjusted when the relative position of the first refractive optical element and the second refractive optical element is adjusted.
