Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a lighting structure for an instrument that integrates an internal member and a light shielding plate.

BACKGROUND TECHNOLOGY As shown in FIG. 3, a conventional meter of this type has a meter body 2 attached to a meter housing 1.
A pointer is rotatably provided on a dial 3 at the top of the instrument body 2, and a transparent protection plate 5 is provided thereon. Further, a lamp 8 fitted into a socket 7 is projected from a cylindrical receiving part 6 at the lower part of the instrument housing 1, and a mounting tube 10 having a light shielding plate 9 is attached to this cylindrical receiving part 6 (as shown in Fig. 59−65404
(see publication).

In this conventional meter, balanced illumination is achieved by directly blocking light from the dial side of the meter housing by the light shielding plate 9 and once reflecting it inside.

On the other hand, if the instrument housing is a dark color such as black, the light from the illumination bulb will not reflect efficiently towards the display, so it may be difficult to effectively reflect the light from the illumination bulb by, for example, installing a brightly colored inner case inside the instrument housing. There are structures that provide illumination, and there are also structures that provide colored illumination by incorporating a board material of an arbitrary color to adjust the illumination color and reflecting the illumination light onto this.

Problems that the invention aims to solve However, even when providing internal materials such as the inner case and plate materials as described above, a light shielding plate has traditionally been used, and the interior material and the light shielding plate are separate and dedicated parts. As a result, there were problems in that the number of parts was large and assembly was time-consuming.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a light-shielding plate above the illumination light disposed in the instrument housing, and the illumination light blocks the light-shielding plate, etc. In a lighting device that illuminates a display section such as a display board or a dial board, an internal material that can diffusely reflect the light from the illumination lamp is provided along the inner wall of the instrument housing, and the light shielding plate is integrated with the internal material. It is characterized by the formation of

Effect This invention uses lighting brightness adjustment and colored lighting to
By forming the light-shielding plate integrally with the internal material installed in the instrument housing, the light-shielding plate can be set at the same time as the internal material is assembled to the instrument housing, reducing the number of parts and manufacturing effort.

Embodiment 1 FIG. 1 shows an exploded perspective view of a meter according to an embodiment of the present invention, in which a cylindrical receiving portion 14 into which a lamp 13 attached to a socket 12 is inserted is provided inside the meter housing 11. and this instrument housing 1
The internal member 15 inserted into the meter housing 1 is provided with a light shielding plate 16 at the position of the cylindrical receiving portion 14, and when the internal member 15 is attached to the instrument housing 11, it is configured as shown in FIG.

In the instrument of this embodiment configured in this way, the light shielding plate 16 is formed integrally with the inner member 15, so that the inner member 15 only needs to be attached to the instrument housing 11 during assembly, which saves time and effort for assembly. The advantage is that it can be saved.

Embodiment 2 FIG. 3 shows a sectional view of a meter according to another embodiment of the present invention, in which a lamp 1 is attached to the meter housing 11.
An internal member 15, which is fitted with a socket 12 and which is mounted inside the meter housing 11, is formed into a plate shape, and a light shielding plate 16 is formed integrally with a part of this internal member 15.

The instrument of this embodiment configured in this manner can also obtain the same effects as those of the above embodiment, but the fact that the internal member 15 is shaped like a plate can be used particularly for colored lighting.

Note that the socket 12 is installed on the instrument housing 1.
1, a cylindrical receiving part may be formed in the internal member 15 and the holding part may be held by this.

Effects of the invention As is clear from the above explanation, the invention achieves two functions in one part by forming a light shielding plate integrally with the internal material inside the instrument housing, by adjusting the brightness of lighting and by coloring the lighting. This can be achieved by reducing assembly man-hours and the number of parts, resulting in an extremely effective structure.
