20090073708 | Vehicle interior illumination system - There is provided a vehicle interior illumination system wherein a linear illumination unit having an elongated linear illuminating portion which extends in a longitudinal direction of a vehicle passenger compartment ceiling is provided along each of left- and right-hand edges of the vehicle passenger compartment ceiling and light emitted from the linear illuminating portion directly illuminates the vehicle passenger compartment. | 03-19-2009 |
20090251911 | In-vehicle illumination device - In an in-vehicle illumination device including: a room lamp section provided with a first light source section, and a light guide plate that guides a light of the first light source section from an end surface thereof and emits the light from a front surface thereof; a first switch for use by the room lamp section; and a vanity mirror section provided with a mirror, when the first light source section is turned on through operation of the first switch, a mode change is made to a room lamp illumination mode in which a first illumination light comes from the room lamp section, and also when the vanity mirror section is in use, the first light source section is turned on, and a mode change is made to a vanity mirror illumination mode in which a second illumination light comes from the room lamp section. The resulting in-vehicle illumination device can be excellent in practicality with the smaller size, and can achieve improvement in terms of design. | 10-08-2009 |
20090251912 | In-vehicle illuminination device - In an in-vehicle illumination device including: a room lamp section provided with a first light source section and a light guide plate, a map lamp section provided with a second light source section and a lens, a first switch for use by the room lamp section, and a second switch for use by the map lamp section, a light source configuring the first light source section and a light source configuring the second light source section are mounted on any same heat sink member. In the resulting in-vehicle illumination device, measures are taken against heat generation, and the reduction of size and weight is achieved. The design quality of the illumination device can be also improved. | 10-08-2009 |
20090251920 | Scuff plate - A scuff plate has a first light guide element having a groove of predetermined shape formed in an underside of the element when viewed from below, a first light source that guides light to the first light guide element, light emission unit that is disposed below the first light guide element and that upwardly emits light differing in color from the first light source, and a half mirror layer interposed between the first light guide element and the light emission unit. Light from the first light source is guided to the first light guide element, and the guided light undergoes reflective diffusion at the groove (a character section). As a consequence, a desired character, or the like, is luminously displayed. In the meantime, light generated by the light emission unit exits through the first light guide element, whereupon an area (a background area) other than the groove (the character section) is illuminated in color that differs from the color of light from the first light source. | 10-08-2009 |
20100080010 | Vehicle interior lighting device - 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. | 04-01-2010 |
20100165650 | Lighting device - In a lighting device provided on a ceiling of an interior of a vehicle, the lighting device has: a map lamp including: a case; a first light guide plate accommodated in the case, and having a light incident area on an end face and a light radiation area on a flat plate surface of the interior side of the vehicle; a first light source part having a plurality of LED lamps, the LED lamps being opposed to the light incident area and arranged in an array; and a prism lens provided in the light radiation area side of the first light guide plate. The map lamp allows the light of the first light source part to be incident on the first light guide plate from the light incident area, radiates the light from the light radiation area to convert the light into a planar light, and then converts the light into a light advancing in a prescribed direction to light a prescribed area in the interior of the vehicle. | 07-01-2010 |
20100165661 | Lighting device - A lighting device includes: a light guide plate having a light incident part in an end face and a light radiation part in a flat plate surface; a light source part opposed to the light incident part; a light shield member with which an area near the light incident part on the flat plate surface of the light guide plate is covered; and a switch part including a switch main body, a switch knob and a pressing member connected to the switch knob to press the switch main body by pressing down the switch knob. An end part of the switch knob opposed to a center of the flat plate surface of the light guide plate is located on the light shield member, and the end face of the light guide plate is located between a first virtual line passing the end part of the switch knob and perpendicular to the flat plate surface of the light guide plate and a second virtual line passing the center of the switch main body and perpendicular to the flat plate surface of the light guide plate. | 07-01-2010 |
