  • Patent number: 10414330
    Abstract: A vehicle signaling light includes a first light source, a first plate light guiding lens, a second light source, and a second plate light guiding lens. The first plate light guiding lens includes a light incident portion to receive light from the first light source in a direction parallel to the plate surface and a light output surface through which the light having been guided is allowed to exit, and the light incident portion has upper and lower expanded portions. The second plate light guiding lens receives light from the second light source in a direction perpendicular to the plate surface and causes the light to exit from the light guiding lens in the direction parallel to the plate surface. The first and second plate light guiding lenses are stacked on each other to configure the vehicle signaling light including a turn signaling lamp function and a DRL function.

  • Patent number: 10352525
    Abstract: A DRL unit as a vehicle signaling light can include: an LED light source; and a plate light guiding lens formed from a light guide plate. The light guide plate includes: a light guide plate main body having a light output surface; and a light entrance portion that is formed to be continuous with the light guide plate main body and includes a light incident surface opposite to the light source and upper and lower expanded portions. The upper and lower expanded portions are integrally formed with the light entrance portion on top and bottom surfaces of the light entrance portion so as to expand in the thickness direction of the light guide plate main body. Here, the upper and lower expanded portions can have asymmetric cross sections in the thickness direction and different sizes when seen in a top plan view.

  • Patent number: 10168017
    Abstract: A vehicle combination lamp including lamp units of high use efficiency can be provided. Among a plurality of lamp units constituting the combination lamp, a first lamp unit can be configured to include two types of light sources, namely, white light sources and orange light sources and a light guide bar that takes in light from the light sources and emits the light in a predetermined direction. White light and orange light that are emitted from the white light sources and the orange light sources, respectively, and guided through and emitted from the light guide bar can contribute to a DRL function and a turn signal lamp function, respectively.

  • Patent number: 9033561
    Abstract: A vehicle lighting unit can include LEDs and at least two long light guide bodies arranged adjacent to each other. At least two light transmitting lenses can be disposed in front of the at least two light guide bodies. The at least two light guide bodies each can include a gap portion interposed therebetween. A first end portion of the light transmitting lens can be positioned at the gap portion so that the first end portions of the light transmitting lenses overlap with each other in a front-rear direction. The first end portions of the at least two light transmitting lenses can have a surface processed portion on its front surface. The surface processed portions can be configured to direct light exiting through the respective first end portions of the at least two light guide bodies forward.
