[0056] (lamp body)

[0057] figure 1 It is a perspective view of a vehicle 10 mounted with the lamp body 1 according to the first embodiment viewed from the rear.

[0058] The lamp body 1 is suitable for, for example, a tail lamp or a stop lamp provided at the rear end of the vehicle 10 . The lamp body 1 emits light toward the rear of the vehicle 10 .

[0059] figure 2 It is an external perspective view of the lamp body 1 of the first embodiment. image 3 is along figure 2 A cross-sectional view of the lamp body 1 along line III-III.

[0060] Such as figure 2 As shown, the lamp body 1 is formed in a ring shape centered on an axis C along the front-rear direction of the vehicle 10 . In the following description, sometimes the direction along the axis C of the lamp body 1 is simply called the axial direction, the direction perpendicular to the axis C is called the radial direction, and the direction around the axis C is called the circumferential direction. The irradi...

Abstract

The invention provides a lamp body which can restrain enlargement and can further show the sense of depth. The lamp body includes a light source (5), a light guide body (6) configured to cause light (L) from the light source to be guided and cause the light to be emitted from a light emitting surface (45), a reflector (7) configured to cause the light, which has exited from a light guide exit surface (65b, 66b) of the light guide body, to be reflected toward a side of the light emitting surface; and a half mirror (4) disposed to face the reflector (7) and having a reflection area where the light (L) reflected by the reflector (7) is reflected toward a side of the reflector and a transmission area where the reflected light is transmitted. The light guide body (6) has: a first light guide lens (61) that guides light (L) from the light source (5) in a first direction; and a second light guide lens (62) having a light guide emission surface for emitting light (L) in a second direction intersecting the first direction, the first light guide lens and the second light guide lens being disposed in a state of being in contact with each other.

Description

technical field [0001] The invention relates to a lamp body. Background technique [0002] Conventionally, in lamp bodies for vehicles such as tail lamps, a structure in which a light source and a light guide are combined is known. In these lamp bodies, in order to express a sense of depth while reducing the thickness, various techniques have been proposed to make the light from the light emitting surface appear three-dimensional by reflecting the light from the light source multiple times inside. [0003] For example, Patent Document 1 (Japanese Unexamined Patent Publication No. 2017-92010) discloses a structure of a light guide having a light guide that emits a part of light from a light source in one direction. A light exit surface; a light guide incident surface for the light emitted from the light guide exit surface; and a light guide reflective surface that reflects another part of the light from the light source or the light incident from the light guide incident sur...
