  • Patent number: 8950916
    Abstract: Disclosed is a vehicle light fitting unit that can include a plurality of light sources, a reflecting plane which diffusely reflects light emitted from the plurality of light sources, and a lens which emits the light, which is diffusely reflected by the reflecting plane, to a front direction. The plurality of light sources can each be provided so that a pitch between one light source and another light source adjacent to the one light source is shorter than a light path length from the one light source to the lens passing through the reflecting plane.

  • Patent number: 8752990
    Abstract: A vehicle light can allow light to be emitted more uniformly through an elongated area from a fewer number of light sources as compared with a conventional one. The vehicle light can include an outer lens, a plurality of light sources arranged along the outer edge of the outer lens for emitting light in an optical axis direction orthogonal to the arraying direction thereof, an inner lens including a light guide portion elongated in the arraying direction of the light sources and disposed along the optical axis of the light sources, for dispersing the light in a longitudinal direction of the lens and emitting in the optical axis direction, and a first diffusion reflector and second diffusion reflectors configured to be elongated in the longitudinal direction of the inner lens and disposed in the optical axis direction of the lens.

  • Patent number: 8740429
    Abstract: A vehicular lamp can include a guiding lens having a polygonal outline. The guiding lens can include divided portions around the optical axis with an equal center angle. The divided portions can each have an incidence face, a reflection face that can reflect to an optical axis direction light emitted from a light source and having passed through the incidence face, and a light-exiting face that can allow the light from the reflection face to pass therethrough to be projected in an illumination direction of the vehicular lamp. Each divided portion can have an outer-diameter end of the light-exiting face or reflection face at a position farthest from the optical axis within a plane including the maximum radius portion of the divided portion and the optical axis.

  • Patent number: 8702281
    Abstract: A light fixture unit can include a light source having an optical axis and a light guide body. The light guide body can include a light incident portion at a front of the light source protruding from a first surface, a light exit portion formed to be elongated in a first direction on a second surface, and a light guide portion. The light incident unit can be configured to make light enter into the light guide body while converting the light into parallel light in a second direction. The light guide portion can include second reflection surfaces disposed to provide a recess on the second surface, each of which is inclined at 45 degrees with respect to the optical axis outward in the first direction individually, and third reflection surfaces which make light reflected internally on the second reflection surfaces in the first direction reflected internally in the second direction toward the light exit portion.

  • Patent number: 8591077
    Abstract: A lens and a lighting fixture utilizing the same provides a plurality of LED light sources as a single light source with a simple configuration. The lens is used with a plurality of light sources in combination and can have a single focus. The lens can include a plurality of light incident portions each disposed so as to face each of the plurality of light sources, the plurality of light incident portions collimating light beams emitted from the plurality of light sources in parallel with a predetermined optical axis while guiding the light beams inside the lens. A light exiting portion can include a refracting surface disposed on optical paths of the collimated light beams guided from the plurality of the light incident portions into the inside of the lens, with the light exiting portions causing the collimated light beams to exit and be converged on the single focus. A lighting fixture can utilize the lens described herein.

  • Patent number: 8562191
    Abstract: A vehicle light can project light beams through ring-shaped or arc-shaped light exiting surfaces, and among them the outermost and innermost light exiting surfaces are brighter than the others. The vehicle light can include a light emitting element having an optical axis and a light guide lens having an incidence surface on which light beams from the light emitting element at a certain angle (?4 to ?5) impinge, reflection surfaces reflecting the light beams so that the light beams are parallel to each other, and light exiting surfaces configured to allow the reflected light beams to pass therethrough. In this vehicle light, light beams emitted at a certain angle (?4 to ?4a where ?4<?4a<?5) can be projected through the farthest light exiting surface from the optical axis.
