VEHICLE LAMP ASSEMBLY
First Claim
1. A vehicle lamp assembly comprising:
- a lamp body;
a front cover which forms a lamp chamber together with the lamp body;
a first lamp section comprising a light source and a reflector which reflects light from the light source; and
a second lamp section comprising a first light emitting device, a second light emitting device, a light guide member, and an optical component,wherein the first lamp section and the second lamp section are disposed inside the lamp chamber,wherein the light guide member comprises;
a base end face from which the light guide member extends in a strip shape along the front cover;
a functional portion comprising a diffusing front surface which diffusely emits light from the first light emitting device; and
a decorative portion comprising an internally reflecting rear surface which reflects light from the second light emitting device toward the front cover,wherein a light emitting area of the decorative portion is larger than a light emitting area of the functional portion,wherein the optical component is disposed on a rear side of the functional portion to guide the light from the first light emitting device toward the diffusing front surface, andwherein the second light emitting device is disposed such that the light emitted therefrom is incident on the base end face of the light guide member.

Abstract
A vehicle lamp assembly includes a first lamp section and a second lamp section, which are disposed inside a lamp chamber defined by a lamp body and a front cover. The first lamp section includes a light source and a reflector which reflects light from the light source. The second lamp section includes a first light emitting device, a second light emitting device, a light guide member, and an optical component. The light guide member includes a base end face from which the light guide member extends in a strip shape along the front cover, a functional portion having a diffusing front surface which emits light from a first light emitting device, and a decorative portion having an internally reflecting rear surface which reflects light from a second light emitting device. A light emitting area of the decorative portion is larger than that of the functional portion. The optical component is disposed on a rear side of the functional portion to guide the light from the first light emitting device toward the diffusing front surface. The light emitted from the second light emitting device is incident on the base end face.

15. A vehicle lamp assembly comprising:
-
a lamp body; a front cover which forms a lamp chamber together with the lamp body; a first lamp section comprising; a light source; and a reflector which reflects light from the light source; a second lamp section comprising; a first light emitting device; a second light emitting device oriented in a same direction as the first light emitting device; a circuit board shared by the first and second light emitting devices; a light guide member comprising; a base end face from which the light guide member extends in a strip shape along the front cover; a functional portion comprising a diffusing front surface which diffusely emits light from the first light emitting device, wherein the diffusing front surface comprises cylindrical steps; and a decorative portion comprising an internally reflecting rear surface which reflects light from the second light emitting device toward the front cover, wherein the internally reflecting rear surface comprises stippled dots, wherein a light emitting area of the decorative portion is larger than a light emitting area of the functional portion, wherein a cross sectional area of the decorative portion is gradually decreased as a distance from the second light emitting device becomes longer; and an optical component, which collimates the light from the first light emitting device, disposed on a rear side of the functional portion to guide the light from the first light emitting device toward the diffusing front surface, the optical component comprising a parabolic reflector, wherein the light guide member and the optical component are formed in a one-piece structure, and wherein the second light emitting device is disposed such that the light emitted therefrom is incident on the base end face of the light guide member, wherein the first lamp section and the second lamp section are disposed inside the lamp chamber, and wherein the light guide member is closer to the front cover than the first lamp section. - View Dependent Claims (16, 17, 18, 19)
