A connector terminal portion 43 to be described later is inserted into the terminal hole 14d.

  The power supply metal plate 40 is made of a thick plate substrate having a thickness of about 1 mm and made of an iron-based metal material and having a surface subjected to rust prevention treatment such as galvanization. By using an iron-based metal material, the strength can be improved as compared with a metal substrate mainly composed of copper, and the cost can be further reduced. The thickness is preferably thicker than 0.8 mm from the viewpoint of strength, and preferably within a range not exceeding 2 mm from the viewpoint of processing accuracy and weight. The power feeding metal plate 40 is formed by bending into a bent shape corresponding to the stepped bent portion 12.

A portion of the lower metal plate flat surface 41 c is bent toward the back side of the housing 10 to form a connector terminal portion 43. The connector terminal portion 43 is inserted into the connector portion 18 and electrically connected to a socket (not shown).

  The LED mounting board 30 is formed of a material such as a printed board, and a wiring pattern (not shown) is formed on the surface thereof. An LED light source 31 is mounted on the surface on the lens cover 20 side, and in this embodiment, two surface mount type light emitting diodes are electrically and mechanically fixed with a known material such as solder. . Further, four mounting holes 32 are formed between the LED light source 31 mounting portion of the LED mounting substrate 30 and the edge of the LED mounting substrate, and the two power supply metal plates 40 described above are formed in the two mounting holes. The crimping portion 44 is inserted, and the LED mounting substrate 30 and the power feeding metal plate 40 are integrated by bending and crimping after insertion. If necessary, other electronic components such as resistors and protective diodes are mounted on the LED mounting substrate. Moreover, it is preferable to perform black coating on the surface on the side where the LED light source 31 is mounted.

  Caulking of the caulking unit 44 is performed in the following order. First, the power feeding metal plates 40 are installed in the housing 10. At this time, positioning is performed by attaching the rib holes 42, 42, 42, 42 provided in the power supply metal plates 40, 40 so as to fit into the power supply metal plate mounting boss 14 provided in the housing. Next, the LED mounting substrate 30 on which the LED light source 31 is mounted is attached. At this time, the caulking portion 44 is linearly bent toward the lens cover 20 so that the caulking portion 44 is inserted into the mounting hole 32.

Next, the caulking portion 44 is caulked and bent to integrate the LED mounting substrate 30 and the pair of power supply metal plates 40, 40.

  Further, when the crimping portion 44 is crimped, as shown in FIGS. 4 and 6, the leading end side of the crimping portion 44 is bent so as to be substantially parallel to the surface of the LED mounting substrate 30, and as shown in FIG. It is electrically connected to a wiring pattern (not shown) provided on the surface of the substrate 30 on the lens cover 20 side. 4 and 6, the crimping portion 44 is shown in a bent state. In FIG. 6, the LED mounting substrate 30 is shown as transparent so that the arrangement state of the power feeding metal plate 40 can be easily understood. Show. Further, in order to ensure electrical connection between the caulking portion 44 and a wiring pattern (not shown) provided on the surface of the LED mounting substrate 30 on the lens cover 20 side, both are connected by a conductive material such as solder and used together. It is preferable.

  Further, when the LED mounting board 30 and the power feeding metal plate 40 are integrated at the caulking portion, the upper metal plate flat surface 41a has the back surface (the LED light source 31 is mounted) of the LED mounting board 30 as shown in FIG. It is in surface contact with the back side contact portion 34 on the non-side). By surface contact, heat conduction between the LED mounting substrate 30 and the power feeding metal plate 40 is improved.

  Furthermore, mesh-like ribs that serve as LED mounting board mounting portions 16 are formed on the upper flat surface 13a of the housing in which the upper metal plate flat surface 41a is provided. The mesh-shaped rib is composed of a plurality of ribs erected in a lattice shape, and the power feeding metal plate 40 is placed on the upper surface thereof. Compared to a uniform flat surface in which the mesh-like ribs 16 are not formed, the heat increase of the housing 10 can be suppressed. Further, a part of the mesh-shaped rib is covered with the LED mounting substrate 30 via the power feeding metal plate 40, and a part is covered with the LED mounting substrate 30 without passing through the power feeding metal plate 40. Thereby, the space 17a surrounded by the mesh-like rib 16 is formed on the back surface side of the portion where the LED light source 31 of the LED mounting substrate 30 is mounted. A space 17a serving as an air chamber is provided between the housing 10 and the heat transmitted to the back surface side at a position corresponding to the upper flat surface 13a of the housing 10 can be reduced.

  The process of supplying the power supply metal plate 40 and the LED mounting substrate 30 to the housing 10 is performed by the lower flat surface boss 14c and the LED mounting substrate mounting boss 15 described above. Specifically, heat caulking is performed to fix the power supply metal plate 40 and the LED mounting substrate 30 by applying pressure while the bosses 14 c and 15 are heated to deform the boss. The thermal caulking is performed at a total of four locations of the lower flat surface boss 14c and the LED mounting board mounting boss 15, and the upper flat surface boss 14a and the intermediate flat surface boss 14b function as positioning bosses. is not.

  The lens cover 20 is formed of a transparent resin material, and is molded by a resin material such as acrylic or polycarbonate. Seal legs 22 are formed around the lens cover 2, and are fused and integrated with the peripheral seal portion 17 of the housing 10. The seal leg 22 faces the front opening 11 of the housing 10, and the lens cover 20 has a bowl shape. The strength of the door mirror lamp 1 can be improved by welding the seal legs 22 of the bowl-shaped lens cover 20 to the peripheral seal portion 17.

  A substrate cover 60 is provided between the lens cover 20 and the LED mounting substrate 30 so as to cover the LED mounting substrate 30. FIG. 10 shows a state before the substrate cover 60 is attached, and FIG. 6 shows a state after the substrate cover 60 is attached. The substrate cover 60 is formed of a non-conductive material, for example, a resin material, and is positioned and fixed by a hook structure in which a claw (not shown) provided on the peripheral edge 61 is fitted in a groove provided in the housing. In addition, an opening is provided at a position corresponding to the LED light source 31 of the substrate cover 60, and the LED light source 31 is located in the opening. Furthermore, the surface of the LED light source 31 on the emission direction side is the same color, similar color or black surface as the door mirror housing 4. By using the colors of these systems, it is possible to enhance the sense of unity when not lit.

  In the present invention, the strength of the entire lamp is improved by the stepped bent portion 12 and the power feeding metal plate 40. Further, the strength in a direction different from the direction of the strength improved by the stepped bent portion 12 and the power feeding metal plate 40 is improved by the seal leg 22. Therefore, since the strength is improved by the curved surface, the bent surface, and the thick metal, the thickness of the material of the lens cover 20 and the housing 10 can be reduced, and the weight of the door mirror lamp 1 can be reduced. be able to.

  Further, a part of the lens cover 20 forms a convex portion that protrudes to the surface side, and the convex portion becomes the light emitting surface 1a. The light emitting surface 1a is designed to match the door mirror side surface 2a in design, and is formed to be a continuous curved surface in this embodiment. A prism lens 21 is formed on the inner surface of the light emitting surface 1a, that is, the surface in contact with the lamp chamber 50. The prism lens 21 forms a lens element that refracts the light emitted from the LED light source 44 so as to obtain a predetermined light distribution pattern. In this embodiment, a large number of minute prisms are formed. In the drawing, since the prism lens 21 is very small, it is shown by a straight line in the sectional view.

  When manufacturing the door mirror lamp of the embodiment of the present invention configured as described above, the LED mounting substrate 30 such as a general-purpose printed circuit board, the two types of bent power supply metal plates 40, the housing 10 and the lens cover 21 are provided. All that is required is a small number of parts. Also, the assembly work can be performed by attaching the power feeding metal plate 40 to the housing 10 at a predetermined position, installing the LED mounting board thereon, fixing by caulking, heat caulking the boss, and sealing with the lens cover. good. Each part has a size that is easy to handle, has excellent handleability, and improves assembly. Therefore, the assembling work can be easily performed, and the cost can be reduced as a whole. Moreover, the connector part 18 is also formed integrally, and it is not necessary to prepare the terminal separately. Further, in the present embodiment, since it is installed on the side surface 2a of the door mirror, the LED light source 31 is mounted on the same plane of the LED mounting substrate 30 so as to face the same optical axis direction, and is combined with a prism lens provided thereon. A predetermined light distribution can be obtained. Therefore, the troublesomeness of arranging in different directions so as to have different optical axis directions as in the prior art is also eliminated.

  When the door mirror lamp 1 described above is attached to the door mirror 2, the door mirror lamp 1 integrated as shown in FIGS. 3 and 3 is provided in the notch 4a of the mirror housing 4 at the position of the side surface 2a of the door mirror. Fit from the cover 5 side. At this time, the gasket 45 is fixed around the light emitting surface 1a of the lens cover 20 with a double-sided tape or the like, and the watertightness with the mirror housing 4 can be maintained by fitting it. Thereafter, the assembly is completed by fixing the door mirror cover 5 as shown in FIG. 2 via a seal packing (not shown). The power supply terminal connected to the door mirror lamp 1 is provided with a socket (not shown) in the space between the mirror housing 4 and the door mirror cover 5 and attached to the connector portion 18 to complete the necessary electrical wiring. .

  The door mirror lamp 1 is positioned on the door mirror side surface 2a, and the LED mounting substrate 30 is arranged in a rectangular shape so that the long side is positioned in parallel with the vehicle vertical direction (z direction) of the door mirror side surface 2a. The LED light source 31 is also arranged in parallel with the vehicle vertical direction (z direction). Therefore, the light emitting surface 1a can be provided on the narrow door mirror side surface 2a. By providing the door mirror lamp 1 on this narrow door mirror side surface 2a, it is possible to irradiate light not only in the vehicle lateral direction but also in the vehicle traveling direction and in the direction opposite to the vehicle traveling direction. Therefore, it can be formed so as to conform to standards such as European standards. For example, the light distribution range satisfies a luminous intensity of 0.6 cd to 200 cd in the vertical direction ± 15 ° and in the horizontal direction 5 ° to 60 °. be able to. Further, the power feeding metal plate 40 is disposed in a direction parallel to the horizontal direction. Therefore, since the strength when the door mirror lamp 1 is assembled to the door mirror 2 is increased by the power feeding metal plate, it is possible to prevent deformation and distortion during the assembly. Further, since the power supply metal plate 40 and the movable range of the mirror housed in the door mirror 2 are substantially parallel, the heat from the LED light source 31 radiated through the power supply metal plate 40 is transmitted from the side of the door mirror side surface 2a and Heat can be radiated to the outside from both sides of the mirror.

  Further, when the door mirror lamp 1 is not lit, the light emitting surface of the lens cover is located on the side surface 2a of the door mirror, so that the inside of the lamp chamber 50 is easily observed through the lens cover 20. However, since the substrate cover 60 and the prism lens are provided in the present invention, the LED mounting substrate 30 is hardly observed. Further, since the substrate cover 60 has the same color, similar color or black surface as the door mirror housing 4, the color observed through the lens cover becomes a color consistent with the housing cover 4, and the appearance quality when not lit is improved. It is improving.

  The above embodiment is merely an example in all respects. The present invention is not construed as being limited to these descriptions. For example, the present invention can be applied to a door mirror lamp in which a door mirror lamp is provided on a double mirror cover or three power supply metal plates are used. The present invention can be implemented in various other forms without departing from the spirit or main features thereof.

  The present invention can be applied to a door mirror lamp with improved parts count and ease of assembly.
