Description

  The present invention relates to a vehicular lamp, and more particularly, to a vehicular lamp that includes an defining member that partitions between a plurality of lamp units or between a plurality of light sources.

The vehicular lamp includes an defining member that partitions and forms at least a plurality of lamp units or a plurality of light sources in a lamp chamber formed by a lamp body and a lamp cover.
Examples of the defining member include a reflector, an extension, and an extension reflector. Here, the extension reflector is a reflector used as a decoration around the unit type lamp, and it looks bright when the lamp is observed from the outside and improves the appearance of the entire lamp.

Conventionally, these defining members have been made by bending a metal plate. However, if the shape of the component is complicated, bending of the metal plate becomes extremely difficult, which increases the manufacturing cost. It was.
Thus, for example, the extension reflector disclosed in Patent Document 1 is formed by molding a resin and depositing aluminum on the surface thereof. The rear portion has a rectangular tube-like fixing portion protruding rearward, and a bolt is inserted into the fixing portion, and a nut is screwed into the bolt to fix the lamp body.

  According to such an extension reflector, the surface of the transparent member is provided with a light-impermeable undercoat and the surface of the undercoat is subjected to a reflection treatment, so that it can be easily and inexpensively manufactured and has an appearance. It was possible to improve the appearance decline. Further, since the fixing portion provided in the reflector is in a transparent state without being subjected to undercoat and reflection treatment, the fixing bolt can be seen through, and the fixing operation can be easily performed.

JP-A-6-76609

However, since the extension reflector made of transparent resin has a thickness of about 2 mm and is heavy, it is disadvantageous for improving fuel efficiency when attached to the vehicle body. Further, as the size increases, the mounting strength required for increasing the weight also increases, and the mounting portion becomes larger and the weight further increases.
On the other hand, although a reflector made of a sheet-like material has been proposed for the purpose of reducing the weight, it is difficult to ensure rigidity because it is thin, and in particular, a large extension reflector is difficult to produce because distortion occurs. .

  Accordingly, the present invention has been made in view of the above situation, and an object thereof is to provide a vehicular lamp that includes a lightweight and highly rigid extension or reflector, and that can reduce the manufacturing cost and improve the fuel consumption of the vehicle. To do.

The object of the present invention is a vehicular lamp provided with a defining member that partitions 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. There,
The defining member is provided such that an defining wall protruding in the light emitting direction of the light source is provided at least between the lamp units or between the light sources, and is integrally formed into a predetermined shape by a sheet-like material. This is achieved by the vehicular lamp.

  According to the vehicular lamp having the above-described configuration, the defining member made of the sheet-like material is provided by providing the defining wall protruding in the light emitting direction of the light source at least between the lamp units or between the light sources. A three-dimensional structure is formed by the defining wall, and the defining member has high rigidity. In addition, since the defining member is integrally formed of a sheet-like material and becomes lightweight, the required attachment strength of the defining member can be reduced. In addition, it is possible to integrally form a large complex shape such as a large-area reflector integrated extension for combination lamps. It is possible to form an defining member having

  In the vehicular lamp having the above-described configuration, it is preferable that the light source is formed of a semiconductor light emitting element, and the defining member constitutes an extension for forming a partition between the light sources.

  According to the vehicular lamp having such a configuration, since the light source is a semiconductor light emitting element, the defining member can be an extension that does not require optical design. In this case, since the distance between each light source becomes short, the definition member which defines these becomes compact, and it becomes easy to ensure rigidity. Furthermore, in the case of a semiconductor light emitting device with a small calorific value, it is not necessary to consider the heat resistance of the defining member, so that the shape around the light source can be made similar to a reflector or given a free pattern, and the vehicle The appearance of the lamp is improved.

  In the vehicular lamp having the above-described configuration, it is preferable that the defining member constitutes an extension that partitions and forms the lamp units.

  According to the vehicular lamp having such a configuration, it is possible to produce a wide-area extension over the entire lamp unit with a sheet-like material, which leads to a reduction in the weight of the entire vehicular lamp, and thus low fuel consumption.

Further, in the vehicular lamp configured as described above, convex portions that can be deformed to absorb an assembly error are provided at a predetermined interval on the periphery of the defining member,
It is preferable that the lamp body and the lamp cover sandwich the convex portion to fix the defining member.

  According to the vehicular lamp having such a configuration, the deformable convex portion is provided on the periphery of the defining member that is clamped and fixed between the lamp body and the lamp cover, so that the lamp fluctuates due to a dimensional tolerance or the like. The convex portion is crushed according to the fixing gap between the body and the lamp cover, and even a thin sheet material can be securely clamped and fixed. Moreover, since the defining member is made of a sheet-like material, even if the convex portion is crushed, the overall shape is not affected.

Further, in the vehicular lamp configured as described above, convex portions that can be deformed to absorb an assembly error are provided at a predetermined interval on the periphery of the defining member,
It is desirable that two ribs on the molding extension side and one rib on the lamp unit side sandwich the convex portion to fix the defining member.

  According to the vehicular lamp having such a configuration, the convex portion with which the back surface side (the concave portion side) is in contact between the two ribs on the molding extension side is sandwiched between one rib on the opposite lamp unit side. Therefore, the convex portion can be deformed with a wide range of deformation amounts from a shape projecting toward one rib side to a shape projecting between the two ribs. In other words, even if the attachment error on the lamp unit side is large, the amount of crushing of the convex portion changes greatly, so that even a thin sheet material can be securely clamped and fixed. In this case, the relative position between the molding extension and the defining member is always constant due to contact other than the convex portion.

  In the vehicular lamp having the above-described configuration, it is desirable that the defining member constitutes a reflector-integrated extension corresponding to a plurality of light sources.

  According to the vehicular lamp having such a configuration, the sheet-like material is formed into a three-dimensional structure by the defining wall by being manufactured integrally with the extension, so that high rigidity is ensured and distortion is hardly generated. Therefore, if the reflector is made of a sheet-like material, the rigidity is insufficient, and the disadvantage of distortion due to vibration during traveling can be solved.

  According to the vehicular lamp according to the present invention, the sheet-like material becomes a three-dimensional structure by the defining wall, and rigidity can be ensured even when molded as a wide area reflector integrated extension for a combination lamp. As a result, the weight can be reduced and the required strength of the mounting portion can be set small, thereby reducing the manufacturing cost and material cost. Furthermore, since the complex large-sized shape can be integrally formed, the defining member can be formed in the shape around the light source similar to the reflector or provided with a free pattern, and the appearance of the vehicular lamp can be improved.
