Furthermore, it is preferable that the first reflecting surface is colored in a color different from the color of the light source. In addition, coloring is not limited to only one color, and gradation of three or more colors is obtained by coloring two or more colors.

According to this configuration, it is possible to perform illumination of a color different from the color of the light source. Further, if the indirect light reflecting surface portion and the direct light reflecting surface portion are configured as described above, light of different colors can be emitted to the indirect light reflecting surface portion and the direct light reflecting surface portion. That is, two or more colors of indirect illumination (lighting) can be realized. In addition, it is preferable to use a white light emitting diode as a light source, and if it does in this way, the color given to a 1st reflective surface and the illumination color of a 2nd reflective surface can be made into the same color.

Similarly, the second reflecting surface is preferably formed of a rough surface that diffuses light from the light source.

Hereinafter, with reference to the attached drawings, a case where the electronic device lighting device of the present invention is applied to an AV lighting device will be described. This illumination device illuminates a volume operation knob (object to be illuminated), and illuminates the panel portion of the AV device in a ring shape so that the operation knob is lifted.

As shown in FIG. 1, a panel unit 2 is disposed at the front of an AV device (housing) 1 supported by a chassis (not shown). For this purpose, an operation knob 3 that is rotated is provided. The panel part 2 is comprised by the front panel 4 directly supported by the chassis, and the translucent window panel 5 attached to the front surface of the front panel 4 (refer FIG. 2). A portion of the panel portion 2 where the operation knob 3 is disposed is an opening. The opening edge is formed in a reflector-like shape around the operation knob 3.

As shown in FIGS. 1 and 2, the operation knob 3 has a cup shape in which the center portion of the front wall portion 3a is somewhat raised, and the peripheral wall portion 3b is sharp toward the rear (panel portion side). It is molded into. The inner surface of the operation knob 3 is integrally formed with a shaft attachment portion 3c extending from the center portion of the front wall portion 3a. The shaft portion 7a of the encoder 7 is detachably attached to the shaft attachment portion 3c. ing. The encoder 7 is fixed to a circuit board 10 attached to the opening peripheral wall 9 that constitutes the opening of the front panel 4, and is positioned on a bearing 11 that extends from the opening peripheral wall 9. And the illumination device 20 which illuminates the operation knob 3 is comprised over the area | region of the circuit board 10, the opening surrounding wall part 9, and the operation knob 3. FIG.

The electrical decoration device 20 includes a light source 21 attached to the circuit board 10, a first reflection surface 22 disposed inside the operation knob 3, and a reflector-like front panel 4 so as to face the first reflection surface 22. A second reflecting surface 24 disposed in the hollow portion 23, and a light diffusing member 25 inserted and mounted inside the opening peripheral wall portion 9 between the first reflecting surface 22 and the light source 21 are provided. The light source 21 is composed of a plurality (six in the embodiment) of light emitting diodes 27 that are equally arranged in the circumferential direction around the axis of the operation knob 3, and the optical axis thereof faces the first reflecting surface 22. Thus, it is mounted on the circuit board 10. The light emitting diode (LED) 27 is preferably white.

A deformed cylindrical holder 31 for attaching the first reflecting surface 22 is provided on the inner surface of the peripheral wall portion 3b of the operation knob 3, and a reflecting plate 32 constituting the first reflecting surface 22 is provided on the rear surface of the holder 31. It is attached. The reflection plate 32 is formed by pressing a thin plate material having a metallic luster such as aluminum or stainless steel into an umbrella shape, and a relief opening (the embodiment is circular) through which the shaft portion 7a of the encoder 7 is inserted at the center. (Regardless of shape) 32a is formed. The first reflection surface 22 is disposed so that the optical path from the light source 21 is directed to the second reflection surface (indirect light reflection surface portion) 24. That is, the first reflecting surface 22 is disposed so as to be inclined so that light from the light source 21 reflected by the first reflecting surface 22 is emitted toward the second reflecting surface 24. In this case, the tilt angle and curved surface shape of the first reflecting surface 22 are designed in consideration of the position of the second reflecting surface 24 and the tilt angle and curved surface shape thereof. As described above, the first reflecting surface 22 of the first embodiment is configured by the rear surface of the reflecting plate 32 provided on the holder 31 (the surface facing the second reflecting surface). The first reflecting surface 22 may be configured by performing vapor deposition or the like. The rear end of the peripheral wall 3b of the operation knob 3 is in contact with the end of the reflecting plate 32, and the rear end of the peripheral wall 3b is sharply formed, so that the rear end of the peripheral wall 3b is the second reflecting surface 24. It will be dark and will not be reflected.

The second reflecting surface 24 is a mirror-finished surface of the recess 23 of the front panel 4 and has a dark color so that the white light of the light source 21 is conspicuous. The recess 23 is formed as a curved surface having a concave cross section so that light from the first reflection surface 22 is emitted forward or obliquely forward with a predetermined directivity. In addition, the opening edge part 5a of the wind panel 5 is formed in the shape used as the extension part of the hollow part 23 from a design viewpoint.

The light diffusing member 25 is formed in a cap shape by forming a relief opening 25a through which the shaft portion 7a of the encoder 7 is inserted at the center, and guides the light of the light source 21 including a plurality of light emitting diodes 27 in the circumferential direction. It has the function of a member and the function of a lens that makes the light transmitted toward the first reflecting surface 22 straight. These configurations eliminate illuminance unevenness due to the plurality of light emitting diodes 27, and efficiently guide the light of the light source 21 to the first reflecting surface 22.

The light from the light source 21 passes through the light diffusing member 25 and reaches the first reflecting surface 22, is reflected obliquely outward by the first reflecting surface 22, reaches the second reflecting surface 24, and is further reflected by the second reflecting surface 24. Is emitted forward. That is, the second reflecting surface 24 is illuminated by the indirect light of the light source 21 reflected by the first reflecting surface 22. Thereby, it is illuminated so that the operation knob 3 may be lifted. In this case, since the first reflection surface 22 is inclined so that the light from the light source 21 is directed toward the second reflection surface 24, the first reflection surface 22 is used as illumination light for illuminating the second reflection surface 24. Light can be extracted efficiently. Therefore, with these configurations, the operation knob 3 can be illuminated with low power consumption and brightness.

Next, with reference to FIG. 3, the electrical decoration device 20A according to the second embodiment of the present invention will be described with a focus on differences from the first embodiment. In this embodiment, not only indirect light from the light source 21 reflected by the first reflection surface 22 but also direct light from the light source 21 is reflected by the second reflection surface 22. That is, the second reflecting surface 24 is illuminated with direct light from the light source 21. In this case, the hollow part 23 which comprises the 2nd reflective surface 24 is extended to the front outer side somewhat from the hollow part 23 of 1st Embodiment (it is not expressed on drawing). And the part near the outer side of the hollow part 23 becomes the direct light reflection surface part 41 illuminated with direct light, and the part near the inner side becomes the indirect light reflection surface part 42 illuminated with indirect light. Further, the direct light reflection surface portion 41 and the indirect light reflection surface portion 42 overlap each other (partially overlap), thereby preventing the occurrence of a boundary portion between the illumination portion by direct light and the illumination portion by indirect light. ing. With these configurations, the light from the light source 21 can be used as illumination light for illuminating the second reflecting surface 24 and can be extracted more efficiently, and the operation knob 3 can be illuminated with low power consumption and brightness.

Next, with reference to FIG. 4, an electrical decoration device 20 </ b> B according to the third embodiment of the present invention will be described with a focus on differences from the second embodiment. In this embodiment, the part which comprises the 1st reflective surface 22 of the reflecting plate 32 is colored blue or green. For example, a metal or the like is formed on the surface of the reflecting plate 32 by vapor deposition, and the surface of the reflecting portion 32 after film formation is colored by spray coating of a specified color. If it does in this way, the direct light reflection surface part 41 will copy the color of the light source 21, and will be illuminated in white, and the indirect light reflection surface part 42 will be illuminated by the colored designated color. That is, the operation knob 3 can be illuminated with at least two colors of ring illumination.

Next, with reference to FIG. 5, an electrical decoration device 20 </ b> C according to the fourth embodiment of the present invention will be described with a focus on differences from the third embodiment. In this embodiment, the second reflecting surface 24 is formed as a rough surface instead of a mirror surface. For example, the second reflecting surface 24 is formed by blasting the background of the recess 23. Thereby, the light reflected by the second reflecting surface 24 is radiated forward so as to diffuse. Therefore, the boundary between the white light that illuminates the direct light reflecting surface portion 41 and the designated color that illuminates the indirect light reflecting surface portion 42 is gradationized. Therefore, the operation knob 3 can be illuminated with ring illumination of two or more colors in which the boundary portion is gradation. The second reflecting surface is formed of a rough surface that diffuses light from the light source, thereby enabling the light reflected by the second reflecting surface to be appropriately diffused, and light emitted to the outside from the second reflecting surface ( (Lights) can be expanded.

It should be noted that the present invention can be applied to various electronic devices having a panel unit in addition to the AV device of the embodiment. It can also be applied to illuminations of various operation knobs and switches. Furthermore, when illuminating a switch group or the like, it is also possible to illuminate a straight line (two lines) or a square shape so as to sandwich or enclose the switch group. In this case, it is preferable to form the first reflecting surface on a part of the panel portion.
