Embodiment Construction

[0041] Next, the vehicle lamp according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings. The term "occasion" means the direction of posture when the vehicle lamp is installed on the vehicle.

[0042] figure 1 It is a schematic front view for explaining the vehicle headlamp 10 according to the embodiment of the present invention. figure 1 The illustrated vehicle lamp 10 is a rear combination lamp mounted on the rear of the vehicle.

[0043] like figure 1 As shown, the vehicle lamp 10 includes a lamp body 12 and a transparent cover 14 covering the front opening of the lamp body 12 . The lamp body 12 and the outer cover 14 form a lamp chamber 16, and in the lamp chamber 16, a reverse signal lamp 18 and a tail lamp 20 are provided. The reverse signal lamp 18 and the tail lamp 20 are fixedly supported on the lamp body 12 .

[0044] like figure 1 As shown, the reverse signal lamp 18 is arranged in the lower par...

Abstract

The present invention relates to lamps for vehicles. An object of the present invention is to suppress the luminous intensity of the side surface of the end portion of the plate-shaped light guide portion in a vehicle lamp provided with a light guide body in which the plate-shaped light guide portion is formed between two rod-shaped light guide portions. The tail light (20) includes an LED (21), and a light guide body (23) that internally guides the light from the LED (21) and emits toward the front of the lamp. The light guide body (23) comprises: a first rod-shaped light guide part (25), which guides light incident from the incident end face; a second rod-shaped light guide part (26), which guides the incident light; and a plate-shaped light guide portion (27) formed in the area between the first rod-shaped light guide portion (25) and the second rod-shaped light guide portion (26). The end side surface (27c) of the plate-shaped light guide part (27) is configured so that at least a part of the light traveling in the plate-shaped light guide part (27) faces the first rod-shaped light guide part (25) and the second rod-shaped light guide part (27). The light guide part (26) is totally reflected.

Description

technical field [0001] The present invention relates to a vehicle lamp, in particular to a vehicle lamp using a light guide. Background technique [0002] Conventionally, by arranging a plate-shaped light guide between two rod-shaped light guides, a luminous lamp for a vehicle is known that has a large light-emitting area and improves visibility. For example, in Patent Document 1, a vehicle lamp is disclosed, which includes a first light guide extending from a light incident portion and introducing light from the light incident portion, and extending and introducing A second light guide body for light from the light incident part, and a flat light guide plate formed between the first light guide body and the second light guide body. [0003] [Patent Document 1] Japanese Unexamined Patent Publication No. 2014-7014 [0004] However, in the vehicle lamp disclosed in Patent Document 1, although the light-emitting area can be increased, the light traveling in the plate-shaped l...
