Description

  The present invention relates to a light emitting device.

  Conventionally, various light-emitting devices that display a deep image have been proposed. For example, an incident surface, a light guide plate having a reflection surface and an exit surface on which a reflection region in the shape of an image to be displayed is formed, and a light source located in front of the incident surface, are incident from the incident surface. The light emitting device is configured to display an arbitrary image through the emission surface by reflecting the reflected light forward in the emission direction by the reflection surface, and is a light emitting device that is located behind the light guide plate in the emission direction. A reflective mirror and a half mirror that is positioned forward in the emission direction with respect to the light guide plate, reflects a part of the light traveling from the rear in the emission direction to the rear in the emission direction, and transmits the other part forward in the emission direction Are provided (Patent Document 1).

  According to this light emitting device, the light guide plate is visualized as a plurality of images superimposed at an equal pitch in the thickness direction of the light guide plate. Therefore, there is an effect that an image having a depth can be displayed while reducing the thickness of the light emitting device.

  However, a conventional light emitting device that displays an image with a depth can only display a plurality of display information and patterns displayed in parallel with the display surface of the light emitting device. For example, an image could not be displayed so as to be continuous in the direction perpendicular to the display surface.

JP 2008-145675 A

  The present invention has been made in view of such a problem, and includes not only an image that can be viewed in parallel with the upper surface of the light-emitting device, but also a plurality of surfaces that are oblique or perpendicular to the upper surface. It is a main object to provide a light emitting device that can be visually recognized as being continuously arranged.

  The present invention adopts the following means in order to achieve the above-mentioned main object.

The light emitting device according to the present invention is
A light source member;
A mirror member disposed on the back side;
A half mirror that is arranged on the front side, transmits a part of the traveling light, emits from the upper surface side, and reflects other light in the back direction;
A cylindrical outer frame that supports the mirror member on the back side and the half mirror on the front side, and forms a space between the mirror member and the half mirror;
Between the mirror surface member and the half mirror, a concave portion formed along the inner periphery of the outer peripheral frame and formed at least at a part on the outer peripheral surface side, and a first reflecting member disposed in the concave portion. A light guide member,
The light is emitted from the inner peripheral surface of the light guide member so that part or all of the light introduced from the light source can be visually recognized in the shape of the first reflecting member.

  According to the light emitting device of the present invention, the mirror member and the half mirror are respectively disposed on the back side and the front side of the inner peripheral surface side of the outer peripheral frame formed in a cylindrical shape. Furthermore, the light guide member is arrange | positioned along the internal peripheral surface of an outer periphery frame between the mirror surface member and the half mirror. Thereby, the light emitted from the inner peripheral surface of the light guide member from the outside of the half mirror can be displayed as an image of a surface perpendicular to or oblique to the half mirror. In this way, the surface that appears parallel to the upper surface does not appear to overlap in the depth direction as in the past, but the surfaces that are arranged perpendicular or oblique to the upper surface are continuous in the vertical direction. Seems to be arranged. Therefore, it can be visually recognized as an image having a three-dimensional impression as compared with the conventional case. In addition, by making the inner peripheral surface visible, light can appear to surround the periphery, so that it can be seen as a deep tunnel. At this time, since the first reflecting member is disposed on a part of the outer peripheral surface of the light guide member, the light reflected by the first reflecting member is emitted more strongly from the inner peripheral surface. Compared to the case where there is no reflecting member, it can appear brighter. Furthermore, the form of the 1st reflection member is visually recognized more clearly from the inner surface of the light guide member, and is visually recognized in a shape similar to the shape of the 1st reflection member or the shape of the 1st reflection member. Therefore, by changing the shape of the first reflecting member, it can be appropriately changed so that various shapes can be seen.

  Moreover, the light-emitting device concerning this invention WHEREIN: The surface of the said recessed part may be rough surface processes, such as a satin process, a mat | matte process, or an embossing process, It may be characterized by the above-mentioned. By adopting such a configuration, light is diffused by the rough surface of the recess, so that the form of the recess can be visually recognized more clearly.

  Furthermore, in the light emitting device according to the present invention, the light guide member includes a second reflecting member having a width of two-thirds or less of the width of the upper surface or the lower surface, the outer surface of the upper surface or the lower surface. It may be characterized by being attached to the side. By providing the second reflecting member on the upper surface or the lower surface, light emitted from these surfaces can be introduced again into the light guide member, and light loss is caused by light emitted from the upper surface or the lower surface. And more light can be emitted from the inner peripheral surface. Therefore, the inner peripheral surface can be made brighter. On the other hand, by attaching a second reflecting member having a width of 2/3 or less of the width of the surface or the lower surface to the upper surface or the lower surface and to the outer peripheral surface side, the inner peripheral surface of the upper surface or the lower surface A portion having a transparent surface with no coating in the width range of one third or more on the side is formed. For this reason, the image reflected on the inner peripheral surface can be easily seen through this transparent portion.

  Furthermore, in the light emitting device according to the present invention, the light guide member has a black or white surface on the outer surface of one or both of the first reflective member and the second reflective member, or a sheet of these colors is disposed. It may be characterized by that. By adopting such a configuration, it is possible to prevent light from being emitted from a surface other than the inner peripheral surface. Moreover, the possibility that a surface other than the inner peripheral surface can be seen from the front surface is reduced by making the portions other than the inner peripheral surface black. Therefore, it is possible to prevent an unintended image from being visualized from other than the inner peripheral surface.

  Furthermore, in the light emitting device according to the present invention, the light guide member may be characterized in that a part or all of the inner peripheral surface is formed on an inclined surface with respect to the mirror member. By making the surface other than the vertical surface with respect to the upper surface, surfaces having different brightness can be produced on the inner peripheral surface. Moreover, it can be visually recognized as a three-dimensionally continuous image in the depth direction.

  Furthermore, in the light emitting device according to the present invention, the light guide member may be characterized in that the inner peripheral surface is formed into a curved surface. By adopting such a configuration, a curved surface can be arbitrarily selected and can be visually recognized as a tunnel-like image having various shapes of inner peripheral surfaces.

Furthermore, in the light emitting device according to the present invention, a gap is formed between at least one of the light guide member and the mirror member and between the light guide member and the half mirror. There may be. By adopting such a configuration, the gap can be made continuous in the depth direction as a dark portion like a shadow, and thus can be visually recognized as an image continuous in the depth direction in a striped pattern.

  Furthermore, in the light emitting device according to the present invention, a pattern or display information may be written on the upper surface of the half mirror. By adopting such a configuration, in addition to an image continuous in the depth direction, a pattern or display information is visually recognized as floating on the upper surface.

  Furthermore, in the light emitting device according to the present invention, a pattern or display information may be attached to the surface of the mirror member. By adopting such a configuration, patterns or display information appear to continuously overlap in the depth direction.

The “lower surface” refers to the surface on the back side of the light guide plate.

(First embodiment)
A light emitting device 100 according to the first embodiment is shown in FIG. FIG. 1 is an exploded perspective view of the light emitting device 100 according to the first embodiment. The light emitting device 100 according to the first embodiment mainly includes a light source member 10, a light guide member 20, a mirror surface member 30, a half mirror 40, and an outer peripheral frame 50 for fixing them.

  The light source member 10 includes one or more light emitting diodes (hereinafter referred to as “LEDs”). The light emitting diode may be of any type such as a flat light emitting type, a side light emitting type, or a bullet type. Preferably, a plane emission type is used. The color of light of the LED is not limited, and may be, for example, white, red, orange, yellow, green, blue, indigo or purple, or a combination of these colors. The light source member 10 may include a light source mounting member 11 that can be mounted according to a light emitting diode, a type of power source, and other mounting methods, and a power supply unit (not shown) that supplies power to the LED. As a power supply unit, in order to adapt the power input from the outside to the rating of the LED, it performs step-down, rectification to DC constant current, pulse modulation after rectification, noise removal, etc., and supplies drive power to the LED For this reason, for example, a configuration including a transformer, a rectifier, a capacitor, and the like can be given.

  The light guide member 20 is made of a transparent resin through which light can pass. For example, in addition to a methacrylic resin such as methyl methacrylate or ethyl methacrylate, an acrylic resin such as methyl acrylate or ethyl acrylate, polycarbonate, polyethylene Various materials such as glass can be used. The material is not particularly limited as long as the material has high permeability.

  The light guide member 20 is provided with a through hole in the center and has an inner peripheral surface 22 on the inner side. In order to produce the light guide member 20, for example, a through-hole may be formed in the center of a rectangular plate-like light guide plate, or four beat tree-like light guide members made of elongated rectangular parallelepipeds may be combined. You may produce and it may produce combining the light-guide member shape | molded in the L-shape. As a method for forming the light guide member 20, the light guide member 20 may be cut from a large transparent resin plate or the like by cutting or laser, or may be formed by injection molding or the like. In the first embodiment, as shown in FIG. 2, a large square-shaped through hole 21 having a similar shape is provided at the center of the rectangular plate-shaped light guide plate, and a ring-shaped guide having an inner peripheral surface 22 is formed by the through-hole 21. The optical member 20 is obtained. Of course, the shape of the light guide member 20 is not limited to this, and may be any shape as long as it has a ring shape having the inner peripheral surface 22. For example, as shown to FIG. 3A, a circular ring (20) may be sufficient, and as shown to FIG. 3B, the ring-shaped form (20) which has a some curvature may be sufficient. The cross section of the light guide member 20 is formed in a substantially square shape as shown in the AA cross section of FIG. 2, and the outer peripheral surface 26 has a recess 26 a narrower than the width of the outer peripheral surface 26 of the light guide member 20. Are formed in a straight line shape, and the surface of the recess 26a is formed into a rough surface having irregularities by laser processing. The rough surface may have any form such as satin finish, matte finish, and texture finish. When producing a rough surface, not only the post-processing method described above, but also simultaneously with the formation of the light guide member 20 using a mold such as an injection prepared so that the rough surface can be formed in advance. A rough surface may be formed. In addition, the recessed part 26a is not formed in the introduction part 26b into which the light from the light source member 10 is introduced so that light can be smoothly introduced into the light guide member 20. The light is efficiently diffused by forming the recess 26a on the rough surface. Further, a first reflecting member 27 is adhered to the recess 26a. The first reflecting member 27 is not particularly limited. For example, a white sheet or a tape formed on a mirror surface is used. By providing the first reflecting member 27, the rough surface in the recess 26a can be illuminated more brightly. Further, a black or white sheet 28 may be provided on the outer peripheral surface 26 so as to cover the recess 26a and the first reflecting member 27, or may be applied with a black or white paint. By providing the white sheet 28 in addition to the first reflecting member 27, the luminance of the light emitted from the inner peripheral surface 22 is improved. By providing the black sheet 28, it is possible to prevent light from leaking from an unintended surface.

In the following, a concave portion 26a having a width of 3 mm is formed on the light guide member 20 having a cross section of 8 mm × 10 mm and a length of 240 mm, and a rough surface is produced by sandblasting the concave portion 26a, and then the white first reflecting member 27 is formed on the concave portion 26a. The measurement data which measured the brightness | luminance when a black sheet and a white sheet are each provided when it sticks to and when not sticking are shown. As a light source, an LED unit (model number OY-545) manufactured by SANKI was used, and light was introduced from the end face. As a measuring instrument, Minolta CS-100A was used, and the luminance was measured by placing it at a position 1 m away from the front surface corresponding to the inner peripheral surface.
1. No first reflecting member No sheet 13.9 cd / m ²
2. With first reflecting member Without sheet 26.8 cd / m ²
3. With first reflective member With black sheet 25.2 cd / m ²
4). With first reflective member With white sheet 40.7 cd / m ²

  From the above, it can be seen that the luminance is highest when the first reflecting member 27 and the white sheet 28 are provided. Although the brightness of the black sheet 28 was almost the same as that of the case without the sheet, the shape of the recess 26a could be visually recognized more clearly.

  In the light guide member 20 thus manufactured, light from the light source member 10 is introduced into the light guide member 20 from the introduction portion 26 b and is mainly led out from the inner peripheral surface 22. At this time, since the light is re-entered into the light guide member 20 by the first reflecting member 27 attached to the concave portion 26a and is diffused by the rough surface of the concave portion 26a, the region of the concave portion 26a is strongly illuminated. As seen from the inner peripheral surface 22. The place and number of light to be introduced into the light guide member 20 can be appropriately set according to the form of the light guide member 20 and the light intensity of the light source member 10. In the first embodiment, as shown in FIG. 1, light may be introduced into the light guide member 20 by the light source members 10 (not visible at one place) arranged at the four corners. For example, when the circular ring 20a shown in FIG. 3A is used, the light introduction part 26b may be provided in advance. Furthermore, as shown in FIG. 3B, an introduction portion 26b may be provided so that the light is introduced into the portion with the longest straight line so that the light can reach farther.

  Further, as shown in FIG. 4, the light guide member 20 has a width of 3 minutes with respect to the width of the upper surface 23 and the lower surface 25 so that the inner peripheral surface side is partially exposed on the upper surface 23 and the lower surface 25. The second reflecting member 60 having a width of 2 or less may be disposed on the outer peripheral surface side. By providing the second reflecting member 60, when light incident on the light guide member 20 is led out from the upper surface 23 and the lower surface 25, the light is reintroduced into the light guide member 20 and the inner peripheral surface 22. Light can be efficiently derived from Therefore, compared with the case where the 2nd reflective member 60 is not arrange | positioned, the internal peripheral surface 22 can be made to shine brightly. Therefore, an image continuous in the depth direction can be visually recognized more brightly, and a deeper depth can be seen. On the other hand, the upper surface 23 or the lower surface can be obtained by attaching the second reflecting member 60 having a width of 2/3 or less to the width of the surface or the lower surface to the upper surface 23 or the lower surface 25 and to the outer peripheral surface side. Thus, a transparent portion 23a is formed which is not covered with anything in the range of a width of 1/3 or more on the inner peripheral surface side of 25 and whose surface is transparent. Therefore, when the light diffused by the recess 26a is reflected on the inner peripheral surface 22, an image of the inner peripheral surface 22 can be visually recognized through the transparent portion 23a. Although it does not specifically limit as the 2nd reflective member 60, Like the 1st reflective member 27, for example, a white sheet, a tape formed on a mirror surface, or the like is used. The second reflecting member 60 does not necessarily have to be disposed on both the upper surface 23 and the lower surface 25, and may be provided on any one of the upper surface 23 and the lower surface 25.

  Furthermore, the light guide member 20 may have a black surface on the outer surface of either or both of the first reflection member 27 and the second reflection member 60, or a black sheet may be disposed. Thus, by blackening the outer surfaces of the first reflecting member 27 and the second reflecting member 60, the outer surfaces of the first reflecting member 27 and the second reflecting member 60 that are not originally desired to be visually recognized are visually recognized from the front. The possibility of being reduced can be reduced.

  As shown in FIG. 1, the mirror member 30 is a member that is disposed on the back side of the light emitting device 100 and reflects light emitted from the light guide member 20 to the front side, and one surface is formed as a mirror surface. ing. The mirror member 30 may be, for example, a member obtained by vapor-depositing a metal on the surface of glass or plastic, or a metal sheet itself.

  The half mirror 40 is a member that transmits part of the light emitted from the light guide member 20 or the light reflected from the mirror member 30 on the back side and reflects part or all of the remaining light. For example, a very thin metal such as gold, silver, copper, aluminum, chromium, nickel, titanium, tin, an alloy containing these metals, a metal compound, etc. is thinly deposited or sputtered on the surface of a transparent glass or resin sheet. It is good to use what was coated. In addition, the member which a part is absorbed may be sufficient as well as the member into which all the light is divided into reflection and permeation | transmission. Further, a protective layer such as a hard coat layer may be formed on the surface of the half mirror 40.

  The outer peripheral frame 50 is for holding the light source member 10, the light guide member 20, the mirror member 30, and the half mirror 40 described above, and is the same as the outer peripheral surface 26 of the light guide member 20 in the first embodiment. It is formed in a rectangular cylindrical shape having an inner peripheral surface. Therefore, the light guide member 20 is disposed in this space along the inner peripheral surface of the outer peripheral frame 50. The outer peripheral frame 50 is arranged such that the mirror member 30 is arranged on the back side and the half mirror 40 is arranged on the front side so that a space is formed between the mirror member 30 and the half mirror 40, and light is guided to this space. The member 20 is disposed along the inner peripheral surface of the outer peripheral frame 50. Thus, the outer peripheral frame 50 holds the light guide member 20, the mirror surface member 30, and the half mirror 40 in a stacked state.

  As shown in FIG. 5, the constituent members thus configured are arranged in the outer peripheral frame 50 in the order of the mirror member 30, the light guide member 20, and the half mirror 40 from the back side. The light source members 10 are arranged at the four corners of the outer peripheral frame 50, and light is mainly incident on each of the square sides of the light guide member 20. Of course, the number of the light source members 10 is not limited, and may be 1 to 3 or 5 or more as long as sufficient light can be emitted from the inner peripheral surface 22. Thus, in the light emitting device 100, the mirror member 30 is arranged on the back side, the half mirror 40 is arranged on the front side, and the light guide member 20 is arranged on the outer peripheral surface 26 side between the mirror member 30 and the half mirror 40, respectively. A space is formed in the portion by the through hole of the light guide member 20. This space forms the inner peripheral surface 22 of the light guide member 20, and light from the light source member 10 is emitted into this space.

  According to the light emitting device 100 manufactured as described above, when the light source member 10 is turned on, light enters the light guide member 20, and most of the light is emitted from the inner peripheral surface 22. A part of the emitted light reaches the mirror surface member 30 and the other part reaches the half mirror 40 directly. Part of the light that has directly reached the half mirror 40 is transmitted through the half mirror 40 and emitted to the outside of the light emitting device 100, and part or all of the light that has not transmitted through the half mirror 40 is on the mirror surface member 30 side. Reflected towards. Since the mirror member 30 reflects substantially all of the received light, the light directly incident from the light guide member 20 and the light reflected by the half mirror 40 are emitted to the half mirror 40 again. Part of this light is transmitted through the half mirror 40 and the other part is reflected again by the half mirror 40. Similarly, the transmission and reflection by the incident half mirror 40 and the reflection by the mirror member 30 are repeated, so that the inner peripheral surface 22 of the light guide member 20 has the depth of the light emitting device 100 as shown in FIG. The images are visualized by the half mirror 40 functioning as a display surface as a plurality of images that are continuous at equal pitches in the direction. In other words, it can be visually recognized by multiplexing as if the same pattern of the plurality of inner peripheral surfaces 22 exists in the depth direction. As described above, according to the light emitting device 100 of the first embodiment, it is possible to display an image having a depth many times the thickness of the light emitting device 100 itself. At this time, in the present embodiment, the recess 26a is provided on the outer peripheral surface 26, and the recess 26a is formed in a rough surface, and the first reflecting member 27 is adhered, so the recess 26a. The part of appears brighter.
