Patent number: 9862306Abstract: A vehicle decorative lighting device and a vehicle lamp including the lighting device can include a light guide lens and a light source that can emit various color lights. The light guide lens can includes a front surface including a plurality of convex surfaces so as to emit the color lights having a substantially uniform light-intensity from the front surface. The vehicle lamp can include a lamp room between an outer lens and a housing, and can incorporate various vehicle lamps such as a headlight along with the lighting device in the lamp room. The lighting device can be located in the lamp room so as to emit the color lights along a periphery of the outer lens. Thus, the disclosed subject matter can include providing vehicle lamps including the decorative lighting device having a harmonious favorable light distribution, for example, such that combine a headlight with a position lamp.Type: GrantFiled: July 26, 2016Date of Patent: January 9, 2018Assignee: STANLEY ELECTRIC CO., LTD.Inventors: Toshihiko Yajima, Takanori Tsuchiya

Patent number: 9822961Abstract: An LED optical light engine spotlight which can accommodate a variable number of light-emitting diodes (LEDs) is disclosed. An optical projection lens mounted in front of the LEDs merges the separate LED beams into a single beam, similar to the single beam provided by a halogen light and reflector. A heat sink provides convection cooling up to approximately 100° F. An optional fan provides additional heat dissipation for more extreme conditions. The depicted device can include a vertical tilt of over 200°. Optimally, the depicted device is designed to have a full vertical tilt range between zenith (0 degrees) to horizontal (90 degrees) to full depression (135 degrees). An optional accessory lens provides additional capabilities, including flood lenses, colored lenses and rock guards, for example. The depicted device can be hard wired or wireless. The depicted device can be adapted to many base units and/or pan and tilt platforms.Type: GrantFiled: July 29, 2016Date of Patent: November 21, 2017Assignee: Golight, Inc.Inventors: Albert W. Gebhard, Colton D. Hosick

Patent number: 9809150Abstract: A light assembly includes a carrier. A first high beam light module is rotatably attached to the carrier for rotation relative to the carrier about a first high beam horizontal axis. A first low beam light module is rotatably attached to the carrier for rotation relative to the carrier about a first low beam horizontal axis. The first high beam horizontal axis and the first low beam horizontal axis are parallel with each other. A bar interconnects the first high beam light module and the first low beam light module. An adjustment drive is coupled to the bar. The adjustment drive is operable to move the bar along a bar axis. Movement of the bar along the bar axis simultaneously rotates the first high beam light module about the first high beam horizontal axis, and the first low beam light module about the first low beam horizontal axis.Type: GrantFiled: October 28, 2015Date of Patent: November 7, 2017Assignee: GM Global Technology Operations LLCInventors: Andrzej Wasilewski, Richard Tepper, Jeffrey T.

Patent number: 9732924Abstract: The invention relates to a headlamp lens for a vehicle headlamp, in particular a motor vehicle headlamp. The headlamp lens comprises a body made of a transparent material and having at least one light inlet surface and at least one optically effective light exit surface. The body comprises a light tunnel which transitions into a light-conducting element while making a bend for imaging the bend as a light-shadow line. The body further comprises an orientation structure for orienting the headlamp lens in a vehicle headlamp and/or for orienting the headlamp lens towards a light source for irradiating light onto the light inlet surface.Type: GrantFiled: October 1, 2013Date of Patent: August 15, 2017Assignee: Docter Optics SEInventors: Wolfram Wintzer, Hans Scheibner, Hagen Goldammer

Patent number: 9709237Abstract: A vehicle lamp comprises a reflector, a semiconductor light source, and a projection lens. The lens axis of the projection lens shifts upward relative to the center of a light emission surface. A reflection surface rotates upward about the center or near the center of the light emission surface. The light emission surface rotates upward to face the reflection surface about the center or near the center of the light emission surface. The rotation angle of the light emission surface is greater than the rotation angle of the reflection surface.Type: GrantFiled: April 4, 2014Date of Patent: July 18, 2017Assignee: ICHIKOH INDUSTRIES, LTD.Inventor: Yasufumi Suzuki

Patent number: 9618676Abstract: A light-conducting apparatus includes a light source, a light-conducting member and a light-reflecting structure. The light-conducting member includes a ring-shaped portion, a light-receiving surface and a radially outwardly bulged portion. The ring-shaped portion extends continuously over an entire circumference of the ring-shaped portion in a circumferential direction of the ring-shaped portion. The light-receiving surface causes light from the light source to enter the light-conducting member through the light-receiving surface. The radially outwardly bulged portion is bulged radially outwardly from the ring-shaped portion and causes the light having entered the light-conducting member through the light-receiving surface to enter the ring-shaped portion in one direction in the circumferential direction of the ring-shaped portion.Type: GrantFiled: October 10, 2013Date of Patent: April 11, 2017Assignee: KOJIMA INDUSTRIES CORPORATIONInventors: Katsutoshi Sakanashi, Tomoya Une, Hirokazu Kandori
