Abstract
A lighting tool for a vehicle includes a first light source unit having a plurality of first light emitting elements and a first heat conductive substrate on which the first light emitting elements are mounted, and a second light source unit having at least one or a plurality of second light emitting elements and a second heat conductive substrate on which the second light emitting element is mounted, wherein the first heat conductive substrate is thermally bonded to the second heat conductive substrate in a state in which the first heat conductive substrate and the second heat conductive substrate are overlapped with each other.
Claims13
A lighting tool for a vehicle comprising:
- a first light source unit having a plurality of first light emitting elements, a first heat conductive substrate on which the first light emitting elements are mounted, and a first reflector configured to reflect light emitted from the first light emitting elements toward a direction of advance of the vehicle;
- and
- a second light source unit having at least one or a plurality of second light emitting elements and a second heat conductive substrate on which the second light emitting element is mounted, and a second reflector configured to reflect light emitted from the second light emitting element in the direction of advance of the vehicle,
- wherein the first heat conductive substrate is formed so as to extend from the first light source unit to the second light source unit,
- wherein the first heat conductive substrate is thermally bonded to the second heat conductive substrate in a state in which the first heat conductive substrate and the second heat conductive substrate are overlapped with each other,
- wherein the plurality of first light emitting elements of the first light source unit include at least two light emitting elements in which switching of turning ON and OFF thereof are individually controlled, and
- wherein among the two light emitting elements, a light distribution pattern formed by turning ON one of the two light emitting elements and a light distribution pattern formed by turning ON the other one of the two light emitting elements are formed at different positions with respect to each other in a horizontal direction.
