  • Patent number: 9328885
    Abstract: A vehicle lighting unit includes LEDs mounted on a substrate, and an elongated inner lens configured to receive light from the LEDs and guide the light along its lengthwise direction so as to emit light from its front surface. The inner lens includes a first light guiding section extending in the left-to-right direction and a second light guiding section extending in the vertical direction, and a bending section between the first and second light guiding sections. The bending section includes a first reflection surface and a second reflection surface. The first and second reflection surfaces internally reflect light toward the first and second light guiding sections, respectively. The LEDs include a first LED and a second LED, disposed in the rear of the first reflection surface and the second reflection surface, respectively.

  • Patent number: 7258473
    Abstract: A vehicle lamp can include a first light source located almost at the center of an emission region, and a transparent cover lens arranged to cover the front in the direction of illumination from the first light source. A central reflective portion of the cover lens can be located in front of the first light source to receive light from the first light source and reflect it toward the entire circumference in a direction almost perpendicular to the direction of illumination. A diametrical outer reflective portion can be located at the rim of the cover lens to receive the light from the first light source and reflect it along the direction of illumination for radial emission. The central reflective portion and the outer reflective portion of the cover lens can be integrated with a joint portion of the same material.
