## Abstract

The present disclosure provides a vehicular lamp including a low-beam lamp and a daytime running lamp. The low-beam lamp includes a low-beam LED, a low-beam reflector, and a projection lens. The daytime running lamp includes a DRL LED, and a DRL reflector. The DRL LED is disposed at the rear side of the low-beam reflector to emit a light in a direction which intersects with the optical axis of the vehicular lamp. The DRL reflector includes an extension area that extends to at least the outer side of the projection lens when viewed from the front, and reflects the light from the DRL LED in the extension area to emit the light to the front side of the lamp through the outer side of the projection lens.

## Claims

### Claim 1

A vehicular lamp comprising:
a projector type lamp unit including a light-emitting element mounting unit for a projector type lamp configured to mount a light-emitting element for the projector type lamp, a projection lens configured to project light from the light-emitting element for the projector type lamp to the front side, and a light shield body configured to prevent a light from the outside from being incident on the projection lens and reflect the light from the light-emitting element for the projector type lamp to the projection lens; and
a reflector type lamp unit including a light-emitting element mounting unit for a reflector type lamp configured to mount a light-emitting element for the reflector type lamp, and a reflector for the reflector type lamp configured to reflect the light from the light-emitting element for the reflector type lamp,
wherein the light-emitting element mounting unit for the reflector type lamp is disposed at a rear side of the light shield body of the projector type lamp unit in a depth direction of the vehicular lamp along with an optical axis of the vehicular lamp, and
the reflector for the reflector type lamp includes an extension area that extends to at least the outer side of the projection lens when viewed from the front, and reflects the light from the light-emitting element for the reflector type lamp in the extension area to emit the light to the front side of the lamp unit through the outer side of the projection lens.

### Claim 2 (depends on 1)

The vehicular lamp of claim 1, further comprising a second reflector type lamp unit,
wherein the second reflector type lamp unit includes a light-emitting element mounting unit for a second reflector type lamp configured to mount a light-emitting element for the second reflector type lamp, and a reflector for the second reflector type lamp configured to reflect the light from the light-emitting element for the second reflector type lamp, and
the light-emitting element mounting unit for the second reflector type lamp is disposed such that the light-emitting element for the second reflector type lamp emits a light in a direction which is opposite to a light-emitting direction of the light-emitting element for the reflector type lamp.

### Claim 3 (depends on 2)

The vehicular lamp of claim 2, wherein the light-emitting element for the reflector type lamp and the light-emitting element for the second reflector type lamp emit lights with different colors, respectively.

### Claim 4 (depends on 3)

The vehicular lamp of claim 3, further comprising a third reflector type lamp unit,
wherein the third reflector type lamp unit includes a light-emitting element mounting unit for a third reflector type lamp configured to mount a light-emitting element for the third reflector type lamp, and a reflector for the third reflector type lamp configured to reflect the light from the light-emitting element for the third reflector type lamp, and
the light-emitting element mounting unit for the third reflector type lamp is disposed at the rear side of the reflector for the reflector type lamp such that the light-emitting element for the third reflector type lamp emits light in a direction which is substantially the same as in the light-emitting element for the projector type lamp.

### Claim 5 (depends on 4)

The vehicular lamp of claim 4, wherein at least one of the light-emitting element mounting unit for the projector type lamp, the light-emitting element mounting unit for the reflector type lamp, the light-emitting element mounting unit for the second reflector type lamp, and the light-emitting element mounting unit for the third reflector type lamp is mounted on a common base member.

### Claim 6 (depends on 2)

The vehicular lamp of claim 2, further comprising a third reflector type lamp unit,
wherein the third reflector type lamp unit includes a light-emitting element mounting unit for a third reflector type lamp configured to mount a light-emitting element for the third reflector type lamp, and a reflector for the third reflector type lamp configured to reflect the light from the light-emitting element for the third reflector type lamp, and
the light-emitting element mounting unit for the third reflector type lamp is disposed at the rear side of the reflector for the reflector type lamp such that the light-emitting element for the third reflector type lamp emits a light in a direction which is substantially the same as in the light-emitting element for the projector type lamp.

### Claim 7 (depends on 6)

The vehicular lamp of claim 6, wherein at least one of the light-emitting element mounting unit for the projector type lamp, the light-emitting element mounting unit for the reflector type lamp, the light-emitting element mounting unit for the second reflector type lamp, and the light-emitting element mounting unit for the third reflector type lamp is mounted on a common base member.
