Abstract

A light source for a vehicle includes a first substrate, a second substrate, a first light emitting element, and a second light emitting element. The second substrate is spaced apart from the first substrate. The first light emitting element is coupled to a surface of the first substrate that faces the second substrate. The first light emitting element is configured to emit light through the second substrate. The second light emitting element is coupled to a surface of the second substrate that faces the first substrate. The second light emitting element is configured to emit light through the first substrate.

Claims

1. A light source for a vehicle, the light source comprising:

a first substrate;

a second substrate spaced apart from the first substrate;

a first light emitting element coupled to a surface of the first substrate that faces the second substrate, wherein the first light emitting element is configured to emit light through the second substrate; and

a second light emitting element coupled to a surface of the second substrate that faces the first substrate, wherein the second light emitting element is configured to emit light through the first substrate.

2. The light source of claim 1, wherein the second substrate is oriented substantially parallel to the first substrate.

3. The light source of claim 1, wherein the first substrate includes a substantially transparent portion to allow for light emitted by the second light emitting element to pass therethrough, and wherein the second substrate includes a substantially transparent portion to allow for light emitted by the first light emitting element to pass therethrough.

4. The light source of claim 1, wherein the first substrate and the second substrate are each generally planar.

7. The light source of claim 1, wherein the first light emitting element has a primary light emission axis, and wherein the second light emitting element has a primary light emission axis that is offset from, and is substantially parallel to, the primary light emission axis of the first light emitting element.

8. The light source of claim 1, further comprising a substrate base located at a proximal end of the first and second substrates, wherein the first and second substrates extend outwardly away from the substrate base.

9. The light source of claim 8, further comprising a standard bulb base rotatably coupled to the substrate base by a rotary assembly, wherein the rotary assembly is configured to allow for optical adjustment of the first and second substrates relative to the standard bulb base.

10. The light source of claim 8, further comprising a cap located at a distal end of each of the first and second substrates opposite the substrate base, wherein the cap is substantially opaque.
