Description

[Detailed Description of the Invention] The present invention relates to a vehicular lamp, and more particularly to a novel vehicular lamp that allows the lamp to be used in common.

For example, conventional vehicle lights have different specifications depending on the vehicle model.
Alternatively, molds were made separately for the component parts of lamps depending on the destination, and each product was molded, transported, managed, and assembled. However, in recent years, due to the increase in mold costs, lamps have been proposed in which lenses, housings, etc. are shared. For example, as illustrated in conventional FIGS. 1 and 2, FIG. 1 shows a domestic lamp in which two reflective surfaces b and b' are connected to each other on the inner surface of a housing a, and are arranged on the front surface of the housing a. The two reflective surfaces b,
Light source bulbs f and f are arranged at the focal point of b' via sockets e and e, respectively. Further, the light chamber d is configured as a tail lamp chamber, so naturally the bulbs f and f disposed in this light chamber d are
It is also a valve for the tail.

When the domestic lamp shown in Fig. 1 is shared for export, for example, as shown in Fig. 2, the housing a and the lens c are commonly used, and the lamp chamber d is
It is divided into two parts, and on the right side there is a light room with different functions, such as a backlight lamp room, as shown in the figure.
A light shielding plate g made of metal or the like is used to partition the tail lamp chamber d and the backlight lamp chamber l, and a reflector h having a different focal length from the reflective surface b of the housing a is used as a separate component to separate the backlight chamber d and the backlight lamp chamber l. A lamp chamber 1 is constituted, and a bulb f' for a backlight lamp is disposed within the lamp chamber 1 via a socket e. However, if the lamp for export shown in FIG. A plurality of protrusions j are protruded from the tip of i, and each protrusion j is inserted into a hole provided in the reflector h to place the reflector h on the pedestal part i. The light shielding plate g is fixed by welding and caulking, and the light shielding plate g is fixed by providing fitting portions k, k, etc. on the inner surfaces of the lens c and the housing a, so the light shielding plate and the reflecting mirror can be separated separately. It takes many man-hours to construct, assemble the light shielding plate, and assemble the reflecting mirror, and the large number of parts makes the structure complicated and increases the cost. In addition, not only does the configuration become complicated because multiple pedestals are provided protruding from the reflecting surface of the housing in order to place and fix the reflector, but also because the multiple pedestals are protruded, Even if an attempt is made to obtain light distribution as a tail lamp by using the reflective surface of the housing, there is a drawback that the reflective surface cannot be used more effectively than the plurality of pedestals i.

This idea was made in view of the above-mentioned circumstances.
In particular, the component parts of the light fixture can be shared, without having to be molded separately for each specific vehicle model or destination, and the structure is simple, and the assembly work is simple and easy. The purpose is to provide inexpensive vehicular lighting.

Embodiments of the vehicle lamp of the present invention will be described below with reference to the accompanying drawings.

Figures 3 and 4 show the first embodiment of the present invention, in which 1 is a housing made of synthetic resin;
A lens 2 is mounted and fixed on the front surface of the housing 1, and lamp chambers 3, 3 are formed adjacent to each other. This light chamber 3,3
In this case, parabolic reflecting surfaces 7, 7 are provided on the inner surface of the housing 1, respectively. For example, a bulb 40 for a tail lamp is positioned at the focal point of these reflective surfaces 7, 7.
(only one side shown) is attached to the attachment hole 13 of the housing 1 via the socket 41. In this case, it is used for tail lamps and stop lamps in Japan. When configuring such a domestic housing 1 into a lamp for export, for example, when configuring a rear combination lamp incorporating a backlight lamp depending on the destination,
The lamp chamber 3 for the tail lamp is configured as a backlight lamp chamber 3A. That is, the second housing 5 is installed inside the right tail lamp chamber 3 in order to share the housing 1 and form a backlight lamp chamber 3A having a different function from the left tail lamp chamber 3. The second housing 5 includes a parabolic reflection mounting portion 51 for attaching a reflection portion 58 having a focal length different from the reflection surface 7, a light shielding wall 53 for shielding light from the adjacent tail lamp chamber 3, and a light shielding wall 53 for shielding light from the adjacent tail lamp chamber 3. A mounting portion 54 extending from the light shielding wall 53 to the tail lamp chamber 3 is provided. Furthermore, in this example, the mounting portion 5
An engaging claw piece 52 is integrally formed at the end of the reflective mounting portion 51 on the opposite side of the reflecting mounting portion 51. The second housing 5 and lens 2 form a background lamp chamber 3A. In this backlight lamp chamber 3A, there is a backlight lamp bulb 4.
Set 0. The valve 40 is attached to the attachment hole 13 of the housing 1 via a socket 41.
The mounting portion 54 extending from the light-shielding wall 53 has a protrusion 55 protruding from its tip, and the protrusion 55 is engaged with the engagement portion 14 provided on the housing 1 . This locking portion 14 is formed in advance between the lamp chambers 3, 3. On the other hand, a bent portion 52 is provided at the tip of the engaging claw piece 52.
a, and the bent portion 52a is engaged with the engagement hole 12 previously drilled in the housing 1. To attach the second housing 5 to the housing, first engage the bent portion 52a of the engagement claw piece 52 into the engagement hole 12 from the direction of arrow _P1 , and then the protrusion 5 of the attachment portion 54
5 to the locking portion 14 from the direction of arrow _P2 . Note that when the second housing 5 is attached, the reflective surface 7 is not necessary.

Next, FIGS. 5 and 6 show a second embodiment of the present invention, in which a light shielding wall 63 of the second housing 6 is shown.
A mounting part 64 is extended to the mounting part 64, and a boss 1 is attached to this mounting part 64.
A hole 65 is bored into which the hole 4a is inserted. The boss 14
a protrudes above the partition 10 formed between the lamp chambers 3, 3, and is inserted into the hole 65 and then heat or cold swaged. Furthermore, in this example, ribs 15a, 15a are provided protrudingly on the partition part 10 for positioning the attachment part 64. The second housing 6 includes a parabolic reflecting section 68 for a backlight lamp similar to the reflecting section 58, and a reflecting mounting section 61 to which the reflecting section 68 is attached. Second housing 6
The mounting portion 64 is securely fixed onto the partition 10 of the housing 1 by the ribs 15a, 15a without being displaced when the boss 14a is crimped.

The light shielding walls 53 and 63 in the above example are both extended to the side of the lens 2 to block light to the backlight lamp chamber 3A when the bulb 4 of the adjacent tail lamp is lit, and to light the bulb 40 of the backlight lamp. This ensures that the tail lamp chamber 3 is shielded from light when the lamp is in use.

In the above example, the lamp chambers are configured as the tail lamp chamber 3 and the backlight lamp chamber 3A, but the present invention is not limited to this, and other lamp chambers having different functions may be configured.

As described above, the vehicle lamp of the present invention has at least two light chambers defined by a housing provided with a reflective surface and a lens placed on the front surface of the housing, and one of the light chambers is provided with a reflective surface. In the lamp in which the housing is shared by forming a reflecting portion having a different focal length from the reflecting surface, the lamp includes: a light-shielding wall for partitioning the adjacent light chambers; a mounting portion provided on the light-shielding wall;
The present invention is characterized in that a second housing for the destination, etc., which is provided with the reflecting portion, is disposed within the lamp chamber, so that there is no need to form separate lamps for each destination as in the conventional case. Moreover, by providing an attachment part to the housing on the light-shielding wall, there is no need to install a pedestal part on the reflective surface of the domestic housing, which would interfere with light distribution. , the number of assembly steps can be reduced, and the assembly work is simple.

It should be noted that, as a matter of course, the present invention is not limited to the illustrated embodiment.
