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 that faces a direction perpendicular to the thickness direction that coincides with the emission direction, a reflection surface that is located behind the emission direction and has a reflection region in the shape of an image to be displayed, and emission A light guide plate having a light exit surface located in front of the light source and a light source located in front of the light incident surface, and reflecting light incident from the light incident surface forward in the light emission direction by the reflection surface. A display device configured to display an arbitrary image through the emission surface, wherein the total reflection surface is located rearward in the emission direction with respect to the light guide plate, and the emission direction front of the light guide plate And a semi-reflective transflective layer that reflects part of the light traveling from the rear in the emission direction to the rear in the emission direction and transmits the other part to the front in the emission direction. A featured light emitting device was proposed There. (Patent Document 1).

  According to this light emitting device, the light reflected by the reflective region travels toward the semi-reflective / semi-transmissive layer. Part of this light is transmitted through the semi-reflective semi-transmissive layer, and the other is reflected by the semi-reflective semi-transmissive layer. The reflected light is reflected by the reflection region or the total reflection surface. Part of this light is transmitted through the semi-reflective semi-transmissive layer, and the other is reflected again by the semi-reflective semi-transmissive layer. As described above, the image formed as a latent image on the light guide plate by the reflection and transmission by the semi-reflective / semi-transmissive layer and the reflection by the total reflection surface overlaps at an equal pitch in the thickness direction of the light guide plate. It is visualized as a plurality of images. Therefore, it is possible to display an image having a depth while reducing the thickness of the display 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 that is visible in a direction perpendicular to the display surface cannot be displayed.

(First embodiment)
A light emitting device 100 according to the first embodiment is shown in FIG. FIG. 1A is an exploded perspective view of the light emitting device 100 according to the first embodiment as viewed from above, and FIG. 1B is an exploded view of the light emitting device 100 according to the first embodiment as viewed from below. It is a perspective view. 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, and a half mirror 40. Furthermore, in 1st Embodiment, the frame 50 which fixes these is provided.

  The light source member 10 includes one or more light emitting diodes (hereinafter referred to as “LED 11”) and a substrate 12. The LED 11 may be any type such as a flat light emitting type, a side light emitting type, a bullet type, and the like. Preferably, a plane emission type is used. The color of light of the LED 11 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 power supply unit (not shown) that supplies power to the LED 11. As a power supply unit, in order to adapt the power input from the outside to the rating of the LED 11, step-down, rectification to a constant DC current, pulse modulation after rectification, noise removal, etc. are performed, and driving power is supplied to the LED 11. For this reason, for example, a configuration including a transformer, a rectifier, a capacitor, and the like can be given. Moreover, you may provide LED so that a color and brightness can be controlled. At this time, the control device may be provided outside the light emitting device 100. The substrate 12 is formed in an annular shape in the same manner as the shape of the lower surface 25 of the light guide member 20 described later, and the LEDs 11 are arranged on the upper surface of the substrate 12 at a predetermined interval on the outer peripheral side from half of the width of the substrate 12. ing. That is, the light emitted from the LED 11 is disposed so as to enter only from the outer peripheral side of the light guide member 20.

  The light guide member 20 is made of a transparent resin through which light can pass. For example, in addition to methacrylic resins such as methyl methacrylate and ethyl methacrylate, acrylic resins such as methyl acrylate and 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 has a through hole in the center and is formed in a ring shape having an inner side surface 22 on the inner side. As shown in FIG. 2, the light guide member 20 has a cross-section of a right trapezoid in which an inner surface 22 is arranged perpendicular to the upper surface 23 and a lower surface 25 is formed wider than the upper surface 23 and one corner is a right angle. I am doing. The outer side surface is an outer peripheral slope 24 formed on the slope. In order to produce the light guide member 20, it may be cut out from a large transparent resin plate or the like by cutting or lasering, or may be produced by molding by injection or the like. Moreover, it does not necessarily have to be produced in one piece, and may be produced by forming two pieces by half and combining them, or by dividing them into a plurality of parts and combining them. The surface of the inner side surface 22 may be formed as a smooth surface, but the surface of the inner side surface 22 is roughened with irregularities such as satin processing, mat processing, embossing, etc., by laser processing or the like on the surface desired to be made to emit light. It may be formed on the surface. In the first embodiment, as shown in the AA ′ partial enlarged view of FIG. 2, a recess 22 a is formed along the inner surface 22 at the center of the upper surface 23 and the lower surface 25 of the inner surface 22. The bottom surface of the recess 22a is formed into a rough surface. By making the inner side surface 22 rough, the light is efficiently diffused and light can be emitted more uniformly, making it easier to visually recognize the inner side surface 22. That is, by forming in the recess 22a, light diffuses in the recess 22a and appears to shine in the shape of the recess 22a, so that the pattern of the recess 22a can be formed on the inner side surface 22. In addition, in order to produce a rough surface, not only the post-processing method mentioned above but the shaping | molding of the light guide member 20 using type | molds, such as injection produced so that a rough surface can be shape | molded previously. Sometimes a rough surface may be formed at the same time. As described above, when a part of the inner side surface is desired to emit light more strongly for visual recognition, a part of the inner side surface may be formed into a rough surface. When it is desired to emit light from the entire inner surface, the entire inner surface may be formed into a rough surface. In addition, the shape of the recessed part 22a is not specifically limited, Arbitrary groove shapes can be used. The shape of the recess 22a is not limited to a linear groove, and the recess 22a may be formed in a pattern or character shape. Moreover, you may produce with the convex part which protruded from the inner surface 22 long and elongated continuously instead of the recessed part 22a. A pattern and a character can be visually recognized similarly by the convex part on the inner surface 22.

  Further, as shown in the AA enlarged cross-sectional view of FIG. 2 and FIG. 3, the light guide member 20 has a black sheet 71 after the reflecting member 80 is attached to the entire upper surface 23 and the outer slope 24. Is pasted. Similarly, after the reflecting member 80 is attached to the portion of the lower surface 25 of the light guide member 20 where the light source member 10 is not disposed, the black sheet 72 is attached. Furthermore, after the reflecting member 80 is similarly applied to the portion of the inner side surface 22 of the light guide member 20 other than the concave portion 22a that is not desired to be visually recognized, the black sheet 73 is attached. By attaching the reflecting member 80, the light emitted from other than the concave portion 22 can be reflected again into the light guide member 20, and the light can be efficiently emitted from the concave portion 22a. Further, by covering as much as possible the portion other than the concave portion 22a of the inner side surface 22 to be visually recognized with the black sheet 70, it is possible to reduce the possibility of visually recognizing the surface that is not originally intended to be visually recognized from the upper surface. Instead of sticking the black sheet, it may be colored black or coated.

  As shown in FIG. 1, the mirror member 30 is a member that is located on the lower surface side of the light emitting device 100 and reflects light emitted from the light guide member 20 to the upper surface side, and one upper surface side 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 a part of the light emitted from the light guide member 20 or the light reflected from the mirror member 30 on the lower surface side and reflects a 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 frame 50 is for holding the light source member 10, the light guide member 20, the mirror member 30, the half mirror 40, and the like described above. As shown in FIG. 1, these frames are separated by the upper frame 50 a and the lower frame 50 b. Hold it in place. The upper frame 50a is made so that it can be accommodated in a state where the light source member 10, the light guide member 20, the mirror member 30 and the half mirror 40 can be positioned so as not to move each other. A hole 51 is provided so that the inside can be visually recognized through the half mirror 40. The lower frame 50b holds the light source member 10, the light guide member 20, the mirror member 30, the half mirror 40, and the like housed in the upper frame 50a from the lower surface side. The frame 50 arranges the mirror member 30 and the light source member 10 on the lower surface side in the frame 50 and the half mirror 40 on the upper surface side, and provides a space between the mirror member 30 and the half mirror 40. The light guide member 20 is arranged in a ring shape in this space. As shown in FIG. 2, the constituent members thus configured are arranged in the order of the mirror member 30, the light source member 10, the light guide member 20, and the half mirror 40 in the frame 50 from the lower surface side. The outer inclined surface 24 side that is less than half of the width of the lower surface 25 forms the light source member arrangement surface α, the LED 11 of the light source member 10 is arranged to face the light source member arrangement surface α, and the light emitted from the LED 11 is emitted. It arrange | positions so that it may inject into the outer slope 24. FIG. The frame 50 may be formed integrally with the mirror member 30 and the half mirror 40.

  According to the light emitting device 100 manufactured as described above, when the light source member 10 is turned on, light is incident on the light guide member 20 from the lower surface 25, The light is incident from the surface 25 (α), reaches the outer slope 24, is reflected by the outer slope 24, and then reaches or exits the inner face 22 directly or indirectly. 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 side surface 22 of the light guide member 20 is in the depth direction of the light emitting device 100 as shown in FIG. A plurality of images 22d continuous at equal pitches are visualized by the half mirror 40 functioning as a display surface. In other words, it can be visually recognized by multiplexing as if the same pattern of the plurality of inner side 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 this embodiment, the light from the light source member 10 does not go directly to the inner side surface 22, but is first incident on the outer side slope 24 and reflected or diffused by the outer side slope 24. Light is emitted from the inner surface 22. Therefore, it is possible to reduce the phenomenon in which the light of the LED 11 is directly emitted from the inner side surface 22 and a part of the inner side surface 22 of the light guide member 20 is brightly lit, and the light emitted from the inner side surface 22 is made more uniform. be able to.

Since other configurations are the same as those of the first embodiment, description thereof is omitted. Even when the light source member 10 is disposed to face the outer slope 24, the light emitted from the light source member 10 enters the light guide member 20 from the outer slope 24, reaches the lower surface 25, and is After being reflected by the surface 25, the light reaches and exits the inner surface 22 directly or indirectly.

  Also in the second embodiment, the light from the light source member 10 does not go directly to the inner surface 22, but is first incident on the lower surface 25, and the light reflected or diffused by the lower surface 25 is reflected on the inner surface 22. Since the light emitted from the LED 11 is directly emitted from the inner side surface 22, the phenomenon that a part of the inner side surface 22 of the light guide member 20 shines brightly can be reduced, and the light emitted from the inner side surface 22 can be further reduced. It can be made uniform.

  Also in the third embodiment, the light from the light source member 10 does not go directly to the inner side surface 22, but first enters the light toward the outer slope 24 and reflects or diffuses the light reflected or diffused by the outer slope 24. Since the light emitted from the side surface 22 is directly emitted from the inner side surface 22, a phenomenon in which a part of the inner side surface 22 of the light guide member 20 shines brightly can be reduced and the light emitted from the inner side surface 22. Can be made more uniform.

Those having curved surfaces may be used. The curve may have a form in which the center is swollen or recessed like the surface of the lens, or may be a form such as a part of a surface of a cylinder bent from both sides of the plate material. The combination of the curved direction of the mirror surface member 30 and the half mirror 40 is free, and the surfaces (the lower surface side of the mirror surface member 30 and the upper surface side of the half mirror 40) of both the mirror surface member 30 and the half mirror 40 are swollen.
