  • Patent number: 9162609
    Abstract: A vehicle headlight can form a variable light distribution pattern with a simple structure including a favorable fail-safe. The headlight can include a movable mirror facing a light source unit, a static mirror between the movable mirror and the light source unit and a controller to emit light from the light source unit and to scan the light toward the static mirror using the movable mirror having a default position, where receives the light at a position substantially perpendicular thereto. The controller can enable the headlight to provide various light distribution patterns by varying a scanning method and the movable mirror is configured to return the light toward the light source unit even if it fails to operate properly. Thus, the disclosed subject matter can provide a vehicle headlight that can form various light distribution patterns in accordance with surroundings and can have the simple structure including the favorable fail-safe.

  • Patent number: 7524075
    Abstract: A shock absorbing mounting for a rotating warning light for a light bar is provided by the assembly of the rotator with a base member useful for mounting one or more rotators and other light producing array units. The light bar base member has longitudinal grooves and the mounting enables the rotator to be attached wherever desired along the grooves. The grooves are blind grooves. The rotator has its own base with a plurality of holes in which are provided resilient shock absorbing grommets with holes therethrough. The assembly of the rotator to the light bar base member is via self-threading screws which have heads, parts of which may be washers, which enlarge the diameter of the heads. The screws are of such length that when they engage and are stopped by the bottom of the grooves, the head compresses the grommet sufficiently to provide a resilient shock absorbing connection.

    Abstract: A headlamp adjuster includes an output shaft driven by a co-rotatable gear. Threads on the shaft engage splines in a thin wall boss, the splines having limited circumferential engagement with the screw. The thin wall boss deflects outwardly in response to forces that build in the engagement of the shaft and splines, to release driving engagement between the splines and the shaft.

    Abstract: A universal joint component is used for connecting two members, such as a reflector and a lamp body. The universal joint component includes a shaft, an installation section formed on one end of the shaft, and a spherical head formed on the other end of the shaft. The spherical head includes a joint base, a top end, and at least one gap formed on a side of the spherical head between the top end and the joining base. The gap is formed of a groove or through hole so as to straddle a phantom line substantially passing through a center of the spherical head and perpendicularly intersecting a shaft axis of the shaft. Split head sections are defined by the at least one gap so that the split head sections flexibly deform when the spherical head is inserted into a spherical socket.
