  • Patent number: 9249944
    Abstract: It is provided a vehicle rear lamp structure that can effectively utilize light that is illuminated from a light source. A door side lamp portion of a rear combination lamp has a housing that supports an incandescent bulb for a back lamp, and a lens that covers the incandescent bulb for the back lamp by being fixed to the housing, and transmits light illuminated from the incandescent bulb for the back lamp. Further, a garnish is mounted to the door side lamp portion. A surface at the lens side of the garnish reflects light, that is illuminated from the incandescent bulb for the back lamp, toward a vehicle rear side. Due thereto, light illuminated from the incandescent bulb for the back lamp can be utilized effectively.

  • Patent number: 8992057
    Abstract: A vehicle includes a main lighting control sensor, a body, a housing, an outer lens, and main and expressive lighting assemblies. The sensor generates an output signal in response to a detected vehicle condition such as braking or headlight activation. The lens defines a cavity in conjunction with the housing. The main lighting assembly is positioned within the cavity, and illuminates in response to the output signal. An expressive lighting assembly positioned within the cavity includes clear transparent plates arranged in a stack, with LEDs arranged in multiple rows and columns on a major surface of each plate. Wire arrays connect the LEDs to a control board. The control board receives an activation signal from a device, e.g., a fob, and individually addresses the LEDs to command illumination of the LEDs according to a calibrated LED illumination sequence. A controller may be used for downloading sequences as applications.
