Abstract: A light modifier is disclosed for use in photography, comprising a frame and a screen supported by the frame. The frame comprises a spine member with first and second limbs pivotally connected to the spine member at spaced apart locations thereon. The frame is mounted on an external support with the first and second limbs retaining in screen supporting positions substantially orthogonal to the spine member such that the screen is tensioned between the first and second limbs. The first limb is seated in a first bracket attached to the spine member and the second limb is seated in a second bracket attached to the spine member. The first and second tubular collars are slidingly mounted on the first and second limbs respectively, the first and second tubular collars fitting when the first and second limbs are in the screen supporting position, over apexes of the first and second brackets respectively so as to prevent pivotal movement of the first and second limbs.
Abstract: A reflecting surface consists of an inner surface and an outer surface, and a filament is disposed along the optical axis of the reflector. The inner surface produces a projection pattern extended in the horizontal direction. The upper half of the inner surface produces a projection pattern below the horizontal center line. Of the lower half of the inner surface, a subsection located on one side of the vertical center plane of the reflector produces a projection pattern contributing to formation of the inclined cutline, and the other subsection located on the other side of the vertical center plane produces a projection pattern contributing to formation of the horizontal cutline. The outer surface produces a projection pattern concentrated in a central area. The upper half of the outer surface produces a projection pattern below the horizontal center line.
Abstract: Disclosed is a vehicular headlamp, which has a reflecting surface curved outward, a lens covering the front of the reflecting surface and a filament disposed at a predetermined position at the reflecting surface, whereby the light emitted from the filament is reflected at the reflecting surface to irradiate a low beam. This headlamp further has an auxiliary reflecting surface provided at a position out of the region which extends from the filament and covers the effective reflecting surface of the reflecting surface. The auxiliary reflecting surface is positioned substantially horizontal and substantially parallel to the irradiation direction. The vehicular headlamp with the above structure can therefore produce beams to illuminate overhead signs from the light reflected at the auxiliary reflecting surface while emitting no dazzling light to an approaching vehicle from the auxiliary reflecting surface. Further, this headlamp does not deteriorate the designability of the lens.
Abstract: A headlight for a motor vehicle incorporation devices for measuring the amount of deviation of the beam of light produced thereby from the desired axis. The first deviation measuring device, which is used for measuring the amount of deviation of the beam in the horizontal direction, includes a calibrated rod extending between either the reflector and the headlight body, in the case of a movable reflector type headlight, or between the vehicle body and the headlight body, in the case of a movable unit type headlight. The second deviation measuring device, which is used for measuring the amount of deviation in the vertical direction, includes a level secured to the reflector or headlight body.
