  • Publication number: 20100080010
    Abstract: A vehicle interior lighting device includes a light source disposed in a vehicle, and a rod-shaped light guiding member including an one end face through which light emitted from the light source is inputted a transparent material, and a transparent material for guiding the inputted light from the one end face to an other end in an axis direction of the rod-shaped light guiding member. The rod-shaped light guiding member includes a first light radiation section for radiating light in a direction perpendicular to the axis direction according to a first illumination pattern to illuminate a first irradiated area in the vehicle, and a second light radiation section for radiating light in the direction perpendicular to the axis direction according to a second illumination pattern different from the first illumination pattern to illuminate a second irradiated area in the vehicle.

  • Patent number: 7419285
    Abstract: The invention is an indicator lamp for warning signal to a person who approaches the vehicle to steal a vehicle. The indicator lamp includes a lamp unit including a light emitting diode (LED). The indicator lamp includes a light guide including an elongated portion and a cover portion. The elongated portion receives a light from the LED at one end and conveys the light to a light emitting end. The cover portion covers the LED of the lamp unit and is integrally formed with the elongated portion. The light guide connects with the lamp unit at the cover portion. The indicator lamp prevents rainwater from the top from entering the lamp unit.
