In Patent Literature 1, the LED light source is surrounded by a vertically extending LED holder in order to prevent the light emitted from the LED light source from leaking in the lateral direction.

Japanese Patent Application Laid-Open No. 2005-311021

Although not disclosed in Patent Document 1, the LED light source includes a bullet-shaped LED light source and a flat plate-shaped LED light source. The light-emitting surface of the bullet-shaped LED light source is located above and away from the mounting surface of the substrate on which the LED light source is attached, but the light-emitting surface of the flat LED light source is located near the mounting surface of the substrate. is doing. Therefore, unlike the bullet-shaped LED light source, when a flat LED light source is used, since the light emitting surface is close to the mounting surface of the substrate, there is a problem that light leaks through the gap between the cover member and the substrate.

The present invention has been made to solve the problems described above, and one object of the present invention is to prevent light from leaking through a gap between a cover member and a substrate when a flat LED light source is used. It is an object of the present invention to provide a light source device for an indicator that can suppress this.

In order to achieve the above object, a light source device for an indicator according to a first aspect of the present invention includes a flat LED light source, a substrate to which the LED light source is attached, and a substrate disposed on the side opposite to the substrate with respect to the LED light source. an indicator portion that transmits light from the LED light source; a cover member that surrounds the LED light source; and a light shielding member.

In the indicator light source device according to the first aspect of the present invention, as described above, the cover member that surrounds the LED light source; and a light shielding member provided at a position corresponding to the gap. Accordingly, since the light shielding member is provided at a position corresponding to the gap between the substrate and the cover member, light traveling toward the gap between the substrate and the cover member is blocked by the light shielding member. When an LED light source is used, it is possible to prevent light from leaking through the gap between the cover member and the substrate.

With this configuration, the cover member protrudes from the second surface side of the substrate when inserted into the substrate, thereby effectively suppressing formation of a gap between the substrate and the cover member. Therefore, it is possible to effectively suppress leakage of light from the LED light source through the gap.

As a result, light from the LED light source 1 does not directly reach the ends of the opening 44 in the width direction, but scattered light with lower luminance than the direct light reaches the ends, so that the luminance is lower than that of the portion where the direct light reaches. You can add contrast.

The hole portion 46 is located at a position facing the light receiving surface 81 of the light receiving portion 8 . The size of the hole 46 is set according to the irradiation range of external light that is desired to reach the light receiving surface 81 . Therefore, the light from the operation unit that is desired to reach the light-receiving surface 81 reaches the light-receiving surface 81 by irradiating it at a predetermined angle or less. On the other hand, when the light from the outside other than the operation part exceeds a predetermined angle, it is irradiated to the cover member 4 and is blocked. Also, the cover member 40 is provided at the boundary between the light receiving portion 8 and the LED light source 1 . The cover member 40 is in contact with the indicator portion 3 .
