Abstract
Official abstract text for this publication.
A lighting apparatus includes: a base that is open toward a front and includes a low beam light-distribution pattern forming component; a lens body disposed forward of the base; a first light-emitting device; and a second light-emitting device. Incident light is refracted in a lower portion of the lens body, and the incident light and exiting light travel in substantially same direction in an upper portion of the lens body. The first light-emitting device is disposed behind the lower portion of the lens body, the second light-emitting device is disposed further forward than the first light-emitting device and behind the upper portion of the lens body, and the low beam light-distribution pattern forming component is disposed in front of the first light-emitting device.
First claim
Opening claim text (preview).
The invention claimed is: 1. A lighting apparatus comprising: a base that is open toward a front and includes a low beam light-distribution pattern forming component; a lens body disposed forward of the base; a first light-emitting device; and a second light-emitting device, wherein incident light is refracted in a lower portion of the lens body, the incident light and exiting light travel in substantially same direction in an upper portion of the lens body, the first light-emitting device is disposed behind the lower portion of the lens body, the second light-emitting device is disposed further forward than the first light-emitting device and behind the upper portion of the lens body, and the low beam light-distribution pattern forming component is disposed in front of the first light-emitting device. 2. The lighting apparatus according to claim 1 , further comprising: a first reflector disposed above the first light-emitting device; and a second reflector disposed in front of the second light-emitting device. 3. The lighting apparatus according to claim 2 , wherein the first reflector has a substantially hemispherical shape that is open toward the front, and the second reflector has a substantially conical shape with a diameter increasing toward the front. 4. An automobile comprising: the lighting apparatus according to claim 1 ; and a vehicle body having a front portion in which the lighting apparatus is disposed.
