| 20080232127 | VEHICLE LAMP - A vehicle lamp can suppress dimensions in the depth direction and provide a large emission area with a simple configuration, and has a light-emitting surface of wraparound configuration with impressive appearance and aesthetic qualities. The vehicle lamp can include a light source unit and a light guide lens. The light source unit can include a light source, and a converting part for converting light from the light source to a narrow width light. The conversion part has an emission area for emitting the converted light. The light guide lens can include one end face having a shape corresponding to the emission area of the conversion part, a thin plate-like light guiding portion for guiding the incident light, and another end face being a farthest part away from the incident surface. The light guide lens guides the incident light toward the other end face and emits the guided light from a predetermined surface thereof as it travels on its way through the lens. | 09-25-2008 |
| 20090067186 | VEHICLE LAMP UNIT - In a vehicle lamp unit that is configured to be mounted on a vehicle, a semiconductor light source can be substantially covered with a first reflector and, therefore, the semiconductor light source is not visually observable (or, is difficult to see) from outside the lamp unit even when a projection lens is disposed in front of the opening of the first reflector and spaced from the first reflector so as not to contact the first reflector. Thus, a vehicle lamp unit having a novel design can be provided in which the projection lens appears as if it is floating in air and in which the semiconductor light source is not visually seen or is difficult to be seen from the outside. | 03-12-2009 |
| 20090231875 | VEHICLE LAMP - A vehicle lamp can include a plurality of light source modules each having an LED as a light source, and optical systems for distributing light from each of the light source modules frontward toward predetermined areas or predetermined patterns that are different from each other and which make up a light distribution pattern. Each of the optical systems can be optimized to emit light to a predetermined area, and each of the light source modules' LEDs can be optimally arranged for each of the corresponding optical systems. | 09-17-2009 |
| 20090316423 | LIGHTING DEVICE - A lighting device with a stable high light intensity can effectively dissipate heat generated by an LED so that the light emission efficiency does not deteriorate while the inside temperature distribution can be maintained in an even state. The lighting device can also be configured to prevent snow from adhering onto an outer lens by allowing an outer surface temperature of the lighting device to rise during actuation of the device. The lighting device can also be configured to improve light utilization efficiency. The lighting device can include a semiconductor light emitting device as a light source and can include structure(s) that guides the emission light to a projection lens. The semiconductor light emitting device can be configured to emit light in a reverse or opposed direction with respect to an illumination direction for the lighting device. A projection lens can be disposed in front of the semiconductor light emitting device. An elliptic reflector can be configured to reflect light from the semiconductor light emitting device and to direct the light to the projection lens. A lens holder can be made of metal and the semiconductor light emitting device and the projection lens can be disposed on the lens holder. | 12-24-2009 |
| 20100073951 | LED LAMP FOR LIGHT SOURCE - Whereas incandescent light bulbs and other similar light sources known in the related art emit light in all directions, LED lamps can emit light in a single direction, and this is manifested in the problem of being unable to achieve light distribution characteristics satisfied by conventional headlamp designs. In accordance with an embodiment of the presently disclosed subject matter, an LED lamp for a light source of a headlamp can include an LED chip in the vicinity of the focus of a projection means and a shielding member covering a portion of the LED chip in a formation allowing a light distribution characteristic suitable for a vehicle front-illumination light to be obtained when light from the LED chip is magnified and projected in an illumination direction by a projection lens or the like constituting the projection means. Accordingly, accurate light distribution characteristics can be obtained in a simple manner by projecting in the illumination direction using the projection lens. | 03-25-2010 |
| 20100177526 | OPTICAL LENS AND VEHICLE LIGHTING DEVICE USING THE SAME - An optical lens for use in a vehicle light can be compact and less expensive and has an outer appearance that has a high commercial value and achieves a high light utilization efficiency. The optical lens can include a light incident surface that receives light from a light source and a light output surface to output the light. The light incident surface can include a center light incident surface formed at its center and being convex toward the light source with a plurality of prisms with a polygonal shape formed radially from its center to its periphery. The light output surface can include a toroidal surface corresponding to the center light incident surface and a surrounding light output surface corresponding to the prisms. | 07-15-2010 |
| 20100259153 | LAMP USING LED LIGHT SOURCE - A lamp can include an LED light source and a lens body having a first lens portion and a second lens portion arranged outside the first lens portion, the first and second lens portions being integrally formed with each other. The first lens portion can include a first light-incident surface and a refractive surface to form a main light distribution pattern condensation and refraction. The second lens portion can include a second light-incident surface, a first total-reflecting surface, a ring-shaped light projecting surface including an individual light projecting surface and a second total-reflecting surface, and a third total-reflecting surface. The second light-incident surface can be disposed beside the LED light source and can refract the light reaching the second light-incident surface to let the light enter the inside of the second lens portion. The first total-reflecting surface can totally reflect light entering through the second light-incident surface to condense the light in the front direction. The ring-shaped light projecting surface is disposed to cover an optical path range of light reflected from the first total-reflecting surface and is divided into a plurality of areas. The individual light projecting surface is provided in at least one of the plurality of divided areas and can transmit the light totally reflected from the first total-reflecting surface. The second total-reflecting surface can totally reflect the light from the first total-reflecting surface in the sideward and outward direction. The third total-reflecting surface can reflect light from the second total-reflecting surface to direct the light in the front direction. | 10-14-2010 |
| 20110122637 | VEHICLE LIGHT - A vehicle light can include an LED light source disposed such that the optical axis of the LED light source is directed downward, a first lens disposed forward of the LED light source, a second lens disposed below and forward of the first lens, and a first reflector extending from both sides of the LED light source to a position near the optical axis of the LED light source. The first reflector can be configured to reflect light beams from the LED light source toward the first lens so as to form a wide vertically converged and horizontally diffused light distribution pattern. The vehicle light can include a second reflector disposed at a position below and forward of the first reflector. The second reflector can be configured to reflect light beams from the LED light source toward the second lens so as to form a middle-area vertically converged and horizontally diffused light distribution pattern. The lens can be formed by a toroidal lens that is horizontally elongated and that is formed by horizontally extending an aspherical lens cross section having a focus near the LED light source in an arc shape, or by a cylindrical lens having a horizontal focus line. In particular, the lens can be formed by an upper-half lens portion of such a toroidal lens. The vehicle light can include a light shielding shutter having a first upper edge portion and a second upper edge portion lower than the first upper edge portion. | 05-26-2011 |
