摘要： 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.

摘要： 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 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.

摘要： A headlight can form a light distribution pattern that prevents uneven brightness when the headlight is set to a high beam mode, and also minimizes power consumption when the headlight is set to the high beam mode. The vehicle light can include a multi-focal lens that has a mid-level lens portion, an upper-level lens portion, and lower-level lens portion. A separator plate can have a front edge positioned at or near the focal point of the mid-level lens portion. Light emitting elements can be mounted on top and bottom of the separator plate, respectively. A first elliptical reflecting surface whose first focal point is set at or near the first light emitting element and whose second focal point is set at or near the focal point of the mid-level lens portion can be provided. A second elliptical reflecting surface can also be provided whose first focal point is set at or near the second light emitting element and whose second focal point is set at or near the focal point of the upper-level lens portion. A hyperbolic reflecting surface can be located adjacent the second elliptical reflecting surface and can have an inner focal point set at or near the second light emitting element and an outer focal point set at or near the focal point of the lower-level lens portion. The vehicle light can be configured such that the first light emitting element and the second light emitting element can selectively emit light beams.
