Problems solved by technology

[0009] On the other hand, a reflection part made of a sheet-shaped material for the purpose of light weight has been proposed, but it is difficult to ensure rigidity due to its thin thickness, and it is particularly difficult to manufacture a large extended reflection part due to deformation.

Embodiment Construction

[0045] Refer to the attached Figure 1 Embodiments of the vehicle lamp according to the present invention will be described in detail.

[0046] figure 1 is a front view of the vehicle lamp according to the first embodiment of the present invention, figure 2 yes figure 1 The II-II sectional plane view, image 3 yes figure 1 The III-III cross-sectional view, Figure 4 is figure 1 The IV-IV sectional plane is a view, and the partial enlarged view is a view when a part of the expansion part made of a sheet material is set as a retroreflective part (RR).

[0047] In the first embodiment, for example, the vehicle lamp 100 is described by taking a rear combination lamp installed at the rear of a vehicle as an example, but the vehicle lamp 100 of the present invention may also be used for a headlight or the like.

[0048] Such as figure 1 and figure 2As shown, the vehicle lamp 100 has a lamp housing 15 formed by a lamp body 11 and a lamp cover 13 .

[0049] Such as figure ...

Abstract

The invention provides a vehicular lamp, which has an expansion part and a reflection part with small weight and high rigidity, reduces manufacture cost and improves oil consumption. The vehicular lamp(100) has an expansion part(37) for bounding the reversing light(21), the brake light(23) and the width lamp(25), and bounding the plurality of LEDs(29) and bulbs in the lamp chamber(15) formed by lamp body and lamp cover(13). The expansion part(37) has light source division walls(49a),(49b),(51a),(51b) and unit division walls(47a),(47b),(47c),(47d) protruding in the light emission direction of LED; the walls are integrally formed into specified shapes by sheet-like materials.

Description

technical field [0001] The present invention relates to a vehicular lamp, and more particularly to a vehicular lamp including a partition member that divides any one of a plurality of lamp units or a plurality of light sources. Background technique [0002] The vehicle lamp includes a partition member for partitioning at least one of a plurality of lamp units or a plurality of light sources in a lamp chamber formed by a lamp body and a lamp cover. [0003] As the spacer, there are reflective parts, extended parts, extended reflective parts, and the like. Here, the extended reflector refers to a reflector used as a decoration around the unit lamp to improve the overall appearance of the lamp when the lamp is viewed from the outside. [0004] Conventionally, these spacer members are formed by bending a metal plate, but if the shape is complicated, bending of the metal plate is very difficult, and there is a problem that the manufacturing cost becomes high. [0005] Then, for...
