Abstract
Official abstract text for this publication.
A vehicle lamp includes a lamp unit configured such that emitted light from a light source is emitted toward the front of the lamp via a projection lens. The lamp unit includes first and second light sources as the light source, which are turned on at respective required turning on modes. The first light source includes at least one light emitting element disposed in a vicinity of a rear focal point of the projection lens. The second light source includes at least one light emitting element disposed at a position obtained by being moved from the rear focal point in a front-rear direction above the rear focal point. Light emitting elements including the first and second light source respectively are mounted on the same substrate extending obliquely in the front-rear direction of the lamp relative to a vertical plane orthogonal to the front-rear direction of the lamp.
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicle lamp comprising: a lamp unit configured such that emitted light from a light source is emitted toward the front of the lamp via a projection lens, wherein the lamp unit includes first and second light sources as the light source, which are turned on at respective required turning on modes, wherein the first light source includes at least one light emitting element disposed in a vicinity of a rear focal point of the projection lens, wherein the second light source includes at least one light emitting element disposed at a position obtained by being moved from the rear focal point in a front-rear direction above the rear focal point, and wherein light emitting elements including the first light source and light emitting elements including the second light source are mounted on the same substrate extending obliquely in the front-rear direction of the lamp relative to a vertical plane orthogonal to the front-rear direction of the lamp. 2. The vehicle lamp according to claim 1 , wherein a light emitting area of the second light source is set to a value larger than a light emitting area of the first light source. 3. The vehicle lamp according to claim 1 , further comprising: a second lamp unit configured to selectively form a low-beam light distribution pattern and a high-beam light distribution pattern, wherein the second lamp unit is configured such that brightness of the low-beam light distribution pattern is reinforced by turning on the second light source, and brightness of the high-beam light distribution pattern is reinforced by turning on the first light source. 4. The vehicle lamp according to claim 1 , wherein the substrate is inclined toward the front of the lamp relative to the vertical plane. 5. The vehicle lamp according to claim 1 , wherein the lamp unit includes a pair of reflectors disposed on left and right sides of the second light source, and wherein the reflectors are configured to reflect the emitted light from the second light source toward the projection lens.
