  • Patent number: 9016882
    Abstract: A strobe device of the present invention includes a flash discharge tube having an anode electrode and a cathode electrode on both ends thereof, and a conductive reflector in contact with an outer peripheral surface of the flash discharge tube. The reflector houses a part of the flash discharge tube inside, and functions as an external trigger electrode. The reflector has a bottom that is in contact with a portion of the outer peripheral surface of the flash discharge tube, the portion covering at least an area between the anode electrode and the cathode electrode and a sintered metal of the cathode electrode. This can suppress variation in discharge path at every light emission from the flash discharge tube. As a result, variation in light quantity and variation in light distribution of light emitted from the strobe device can be suppressed.

    Abstract: A strobe device of the present invention includes a light source; an optical element; and reflector having reflecting surface. Reflecting surface includes first reflecting surface formed closer to reflector than from specific reflecting region in reflecting surface; and second reflecting surface formed closer to the optical element. Further, first reflecting surface has a shape curved so as to have its center of curvature inside reflector. Second reflecting surface has a shape curved so as to have its center of curvature outside reflector and to be more remote from an optical axis with decreasing distance to the optical element. This prevents light emitted from the light source from illuminating part other than a desired region.

    Abstract: A studio light and deflection cone softens the harsh light that is produced by studio lighting instruments, in order to show fewer wrinkles and imperfections on the actors' faces and to create more appealing and flattering facial features for the purpose of photography. The cone attaches to the front of a studio lighting instrument. As light is projected into the rear of the cone, it passes through a primary gel frame that is covered with light deflecting material that spreads the beam. Inside the cone, the light reflects off the ultra-white interior of the cone, is intensified, and passes through the secondary gel frame that is covered with light deflecting material. Upon leaving the cone, the light passes through the control grid at the very front of the cone that narrows the spread of the light exiting the cone in degrees to produce a very soft and controlled light.

  • Patent number: 8025417
    Abstract: A lighting apparatus comprises a light panel having a panel frame, and a plurality of LEDs or other light elements secured to the panel frame. A self-contained battery unit securably attaches to the outside of the panel frame. The light panel may have a dimmer switch, and may also be capable of receiving power from a source other than the self-contained battery unit. The lighting apparatus can be mounted to a camera or a stand through adapters. Diffusion lenses or color gels can be integrated with or detachable from the light panel. The lighting apparatus may conveniently be provided in the form of a kit, with one or more of a light panel, self-contained battery unit, compact stand, connecting cable(s), adapter(s), lenses or color gels, and so on, provided in a single package.

  • Patent number: 8021006
    Abstract: A LED array flash for cameras includes a LED array and a controller. The LED array consists of at least one LED light source with first order lens. The LED light source may be further covered with a second order lens. Thus an oblong or round distribution pattern with uniform light intensity is emitted. The controller is used to control flash modes such as low brightness continuous lighting or high brightness pulse lighting with lighting time control so as to save power and avoid overheating.

  • Patent number: 7946719
    Abstract: A photographic light diffusing device comprises a semi-transparent cowl which is adapted to be mounted on a photographic light source, the cowl including an opening through which the photographic light source is visible when the cowl is mounted thereon, and a removable semi-transparent cover detachably mounted on the cowl. In another embodiment, a camera flash system comprises a camera flash unit, and a diffuser unit having an adaptor and a tapered cylindrical body. The adaptor is formed to match the shape of the housing of the camera flash unit so that it may be fitted thereto, and the adaptor extends between the camera flash unit and the tapered cylindrical body of the diffuser unit. The diffuser unit widens from the adaptor to meet the tapered cylindrical body.

  • Patent number: 7810941
    Abstract: The present example provides a flexible and compact system for diffusing light in multiple levels when taking photographs. An adapter capable of coupling many types of flashes is fitted to a first diffusion device. The diffusion device may be fitted inside a light box fitted with a diffusion lens so that additional light dispersion is provided. The light box may be substituted with a black box that tends to direct diffused light for further control over exposure. Various filters may also be used in the system allowing for further flexibility in setting exposure. And finally a system of reflectors and shields allow further control of lighting effects.

  • Patent number: 7780303
    Abstract: An apparatus and methods that includes a gel holder and an optional shade holder that allows a user to add color or eliminate or reduce reflected color and to shape, shade, diffuse, soften, absorb, block, reflect, retract and dim light inside photographic reflectors such as photographic umbrellas or other reflective apparatus. The invention allows a user to mix, blend or shape light at the source and the resulting light can be symmetrical or asymmetrical. The invention allows a user to more efficiently add texture, eliminate hotspots and create shadows by changing positions of a gel holder with a gel and one or more shade holders with shades on a reflector focus tube.

  • Patent number: 7733415
    Abstract: A small illumination apparatus including an optical member less affected by heat from a light source is disclosed. The illumination apparatus has a light source and an optical member closer to a light irradiation side than the light source and having an entrance surface formed as a refractive surface. The entrance surface has a first area receiving a first light component emitting from the light source at an angle smaller than a first angle with respect to an irradiation optical axis and a second area receiving a second light component emitting at an angle larger than the first angle with respect to the irradiation optical axis. The second area is positioned closer to the light source than the first area in the irradiation optical axis direction. Each of the first and second areas is formed a flat surface or a curved surface having a concave shape facing the light source.
