20090196059LICENSE PLATE LAMP - A license plate lamp for radiating light to a surface of a license plate attached to a rear end of a vehicle body includes: a lamp body disposed above the license plate; a light emitting diode disposed within the lamp body, the light emitting diode having an optical axis extending in a vertical direction for emitting light toward a license plate located under the light emitting diode; and a control lens provided between the light emitting diode and the license plate for controlling the light emitted by the light emitting diode so that the light is radiated toward a surface of the license plate. The control lens includes a first control portion for radiating the light emitted by the light emitting diode toward an upper end part of the surface of the license plate, and a second control portion located rearward of the first control portion for radiating the light emitted by the light emitting diode toward substantially a whole region of the surface of the license plate.08-06-2009
20090290370VEHICLE LIGHTING APPARATUS - A lighting apparatus is disposed near an upper end edge of a license plate on a rear side of a vehicle. The lighting apparatus includes a license plate lamp which illuminates the license plate with visible light, and an infrared irradiation lamp which irradiates a region behind the vehicle with infrared light. The license plate lamp includes a first light emitting device which emits the visible light and is supported on a rear surface of a first support plate. The infrared irradiation lamp includes a second light emitting device which emits the infrared light and is supported on a lower surface of a second support plate. A lower end of the first support plate is coupled to a rear end of the second support plate. When seen from behind the vehicle, the license plate lamp is disposed directly above the infrared irradiation lamp.11-26-2009
20100008088LAMP - A lamp is provided. The lamp includes a lamp housing; light emitting diodes (LEDs); a main reflector disposed so as to oppose to the LEDs for reflecting light emitted from the LEDs towards a front side of the lamp; a sub-reflector which is interposed between the LEDs and the main reflector, and which reflects and diffuses the light emitted from the LEDs towards the main reflector; an LED element assembly which extends in parallel with the sub-reflector and comprises a plurality of flat portions, each flat portion corresponding to one of the plurality of LEDs and on which the corresponding LED is mounted, adjacent ones of the flat portions being coupled together by at least one step portion; and a center portion which covers the LED element assembly and the LEDs such that the LEDs are not exposed to the front side of the lamp.01-14-2010
20100060127VEHICULAR INFRARED IRRADIATION LAMP - A vehicular infrared irradiation lamp includes an infrared light-emitting element for projecting infrared light; a visible light-emitting element that emits visible light; and a transparent member provided at least partially adjacent to a light-emitting portion of the infrared light-emitting element. The transparent member radiates visible light received from the visible light-emitting element in a radiation direction of infrared light.03-11-2010
20100149828VEHICULAR LAMP - A vehicular lamp including, in a lamp chamber formed by a lamp body having a front opening and a transparent front cover attached to the front opening, a semiconductor light-emitting element; and an inner lens positioned forward of the semiconductor light-emitting element. The inner lens includes a first light control portion for diffusing light from the semiconductor light-emitting element in a horizontal direction; and second light control portions respectively positioned on left and right sides of the first light control portion, each of which have a reflective surface for reflecting the light from the semiconductor light-emitting element in a predetermined direction.06-17-2010
20110032721VEHICULAR LAMP - A vehicular lamp includes a body that opens forward; an outer cover attached to the body so as to cover the opening; a first light source disposed within a lamp chamber formed from the body and the outer cover; an optical member that reflects first light source light from the first light source forward; a second light source disposed within the lamp chamber; and a light guide in which an end portion thereof receives second light source light from the second light source and an extended side surface thereof radiates forward at least a portion of the second light source light. The light guide is provided at a position that does not block a light component that forms a main light distribution of the first light source light.02-10-2011
20110085344Lamp Unit and Vehicle Lamp - A lamp unit includes at least one light source that emits light in a predetermined direction, and a light guide body including at least one incident surface where light emitted from the light source enters, a first emission surface that emits light entering from the incident surface in a horizontal direction, and a plurality of second emission surfaces that emits light entering the incident surface in a horizontal direction and emits light entering the incident surface to the upper side of the horizontal direction. The second emission surfaces are formed above the first emission surface at different positions in an up-down direction, and are positioned on the back side of the first emission surface so as to be spaced apart from one another in the horizontal direction.04-14-2011
