Description

The present invention relates to a decorative optical member that is used in an illumination unit that uses an LED as a light source, and a calling device that includes the decorative optical member.

In a game arcade where a gaming machine such as a pachinko machine or a slot machine is installed, a calling device for a player in the game or a player who finishes the game to call staff of the game arcade is installed.

The calling device includes an operation unit that is operated by a player as necessary, and a calling illumination unit that is turned on by operating the operation unit.

In addition, in recent years, in addition to the above configuration, the calling device includes a display unit that provides the player with information such as the type and operating status of the gaming machine, and an illumination unit for decoration for decorating the calling device. Things are becoming popular. In this type of calling device, the lighting unit for calling is provided separately from the lighting unit for decoration, or the lighting unit for calling is also used as the lighting unit for decoration, and the operation unit is operated. In some cases, the lighting mode of the illumination unit is changed (for example, see Patent Document 1).

Each of the lighting unit for calling and the lighting unit for decoration includes a light source and a light source cover that covers the light source and has a light transmissive property. This prevents the player or the like from directly looking at the light source in each of the calling illumination portion and the decoration illumination portion.

Such a calling device is installed in an area where the player can operate the operation section and the staff can visually recognize the calling illumination section (for example, an area above the gaming machine).

By the way, in recent years, in order to suppress the power consumption of the illumination unit (light source), an LED (light emitting diode) is being adopted as a light source. However, when an LED is used as the light source, there is a problem that the intensity of light becomes strong in a part of the light source cover and the entire illumination unit (light source cover) cannot be turned on (emits light) in a well-balanced manner.

Specifically, the LED has a narrow light spread (strong directivity), and the light from the LED is concentrated and emitted to a part of the light source cover in front of the LED. As a result, the illumination unit (light source cover) locally emits strong light (lights). That is, the existence (arrangement position) of the LED as the light source is recognized through the light source cover.

As a result, there is a problem that the decorativeness of the illumination unit is deteriorated.

Therefore, according to the present invention, even when an LED is used as a light source, it is possible to suppress local strong light emission in the illumination unit, and to enhance the decorativeness in the illumination unit, and the decorative optical member. It is an object to provide a calling device including an optical member.

The decorative optical member of the present invention includes at least one light guide section formed of a material having a light transmitting property, and the light guide section includes a light entrance section for receiving light from the LED and an opposite side of the light entrance section. And a pair of branch light guides, each of which is continuous with the tip of the light guide section, and which has a second direction orthogonal to the first direction or the second direction as a component. Within a range that overlaps with the pair of branch light guide portions including the emitting portion that extends in the containing direction and that faces the opposite side to the light entering portion in the first direction, and the branch light guiding portion when viewed from the first direction. At least one first hole at least a part of which is located in, and the first hole extends in a third direction orthogonal to the first direction and the second direction, and has a polygonal shape when viewed from the third direction. It is characterized by

According to the decorative optical member having the above-described configuration, since the light guide section is formed of a material having a light-transmitting property, the light entrance section of the main light guide section emits light from a narrow LED (high linearity). When receiving the light, the light enters from the light entrance portion into the main light entrance portion and proceeds in the first direction. Along with this, the light that travels in the first direction in the main light guide section reaches the branch light guide section that is continuous with the tip of the main light guide section. Then, the light guide section has at least one first hole, at least a part of which is located in a range overlapping with the main light guide section when viewed from the first direction in the branch light guide section, and thus reaches the branch light guide section. The generated light reaches the inner peripheral surface of the first hole. Since the inner peripheral surface of the first hole is the interface between the air layer and the substantial part of the branch light guide portion, the light reaching the inner peripheral surface of the first hole is the light reflected by the inner peripheral surface of the first hole. And light transmitted through the inner peripheral surface of the first hole.

Since the first hole extends in the third direction orthogonal to the first direction and the second direction and has a polygonal shape when viewed from the third direction, the two flat surface portions forming the inner peripheral surface of the first hole are the first Spread in a direction that intersects with one direction. Along with this, the light reflected by the inner peripheral surface (flat surface portion) of the first hole does not return to the light incident portion side but is reflected in the branch light guide portion in a direction intersecting the first direction. Further, the light passing through the inner peripheral surface (flat surface portion) of the first hole passes through the first hole and enters the branch light guide portion again from the inner peripheral surface (different flat surface portion) of the first hole.

Then, the light in the branch light guide section reaches the emission section of the branch light guide section and the outer surface on the opposite side. Since these surfaces are also interfaces between the air layer and the substantial parts of the branch light guide section, the light reaching the emitting section and the outer surface is divided into light reflected by the surface and light transmitted through the surface. .. That is, the light in the branch light guide portion is emitted from the emission portion while being repeatedly reflected by the emission portion and the outer surface on the opposite side. As a result, the light from the LED is spread to the emission portion of the branch light guide portion and emitted to the outside.

As one aspect of the present invention, the branch light guide section has a pair of outer surfaces facing outward in the third direction and opposite directions in the third direction, and the light guide section is the first direction in the branch light guide section. It has two first holes arranged in the same row in the third direction within the range overlapping with the light guide section, and one first hole of the two first holes is one of the pair of outer surfaces. It is a non-through hole that is open on one of the outer surfaces, and the other first hole of the two first holes is a non-through hole that is open on the other outer surface of either of the pair of outer surfaces. Good.

According to the above configuration, since the two first holes arranged in the third direction are non-through holes, the light that reaches the two first holes in the light in the branch light guide portion is It is divided into light reflected by the peripheral surface (flat surface portion) and light passing through the inner peripheral surface (flat surface portion) of the first hole. Then, the light that has passed through the inner peripheral surface (flat surface portion) of the first hole passes through the inside of the first hole, and then enters the branch light guide portion again from the inner peripheral surface (different flat surface portion) of the first hole. Further, since the portion between the two first holes is a substance having a light-transmitting property, some of the light in the branch light guide portion may pass through between the two first holes. As a result, the light passing between the two first holes, the light passing through the inner peripheral surface (flat surface portion) of the first hole, and the light reflected by the inner peripheral surface (flat surface portion) of the first hole are finally The light is emitted from the emitting portion toward the outside. Therefore, the emitting portion has a light emitting mode that is strong and weak depending on the place, and is highly decorative.

As another aspect of the present invention, the branch light guide portion has a pair of outer surfaces facing outward in the third direction and facing in opposite directions in the third direction, and the first holes are in opposite directions in the third direction. It may be a stepped hole that is open on any one of the pair of facing outer surfaces and becomes smaller from the one outer surface toward the other outer surface.

According to the above configuration, since the first hole is a stepped hole, the inner peripheral surface (planar portion) that defines the first hole is arranged differently in different positions in the third direction. As a result, the light having different passing positions in the branch light guide portion is dispersed (diffused) without the same behavior. Accordingly, the intensity of the light is added at the emission portion of the branch light guide portion, and the light emission is rich in decorativeness.

As another aspect of the present invention, the pair of branch light guide sections may be arranged in plane symmetry with respect to an imaginary plane that passes through a center line extending in the first direction of the main light guide section.

According to the above configuration, the optical paths in each of the pair of branch light guide portions become uniform. Therefore, as a result of the light from the LEDs being evenly split into the pair of branch light guide portions, the emission portions of each branch light guide portion emit light evenly.

As still another aspect of the present invention, the branch light guide portion has an outer surface that faces outward in the first direction and that faces in a direction opposite to the emitting portion, and the outer surface may be an uneven surface. Good.

According to the above configuration, the light in the branch light guide portion is diffused on the outer surface facing the direction opposite to the emission portion. Therefore, the light that has entered the branch light guide portion is dispersed and reaches the emission portion.

In this case, it is preferable that the outer surface of the branching light guide section facing the direction opposite to the emitting section includes convex stripes and concave stripes extending in the third direction and alternately arranged in the second direction.

According to the above configuration, the outer surface of the convex line and the concave line facing in the direction opposite to the emitting portion is made into an uneven surface. Since the ridges and the ridges extend in the third direction, it is difficult for the light entering the branch light guide portion to be diffused in a direction different from the direction in which the branch light guide portion extends. That is, a large amount of light is guided to the emission section of the branch light guide section.

As yet another aspect of the present invention, the light guide unit further has at least one second hole located between both ends of the branch light guide unit in the extending direction of the branch light guide unit, and the second hole is It may extend in the third direction and have a polygonal shape when viewed from the third direction.

According to the above configuration, the light that has entered the branch light guide section reaches the inner peripheral surface of the second hole of the branch light guide section in the light that is repeatedly reflected by the (emission section and the surface on the opposite side).

Since the inner peripheral surface of the second hole is the interface between the air layer and the substantial part of the branch light guide, the light that reaches the inner peripheral surface of the second hole is the light reflected by the inner peripheral surface of the second hole. And light transmitted through the inner peripheral surface of the second hole.

Since the second hole has a polygonal shape when viewed from the third direction, the two plane portions forming the inner peripheral surface thereof spread in the direction intersecting the first direction. The light reflected by the inner peripheral surface (flat surface portion) of the second hole is reflected in the branch light guide portion in a direction intersecting with the first direction (second direction or a direction including the second direction as a component). Further, the light that has passed through the inner peripheral surface (flat surface portion) of the second hole passes through the second hole and enters the branch light guide portion again from the inner peripheral surface (different flat surface portion) of the second hole. Therefore, the light entering the branch light guide portion is diffused due to the presence of the second hole, and a large amount of light is guided to the exit portion of the branch light guide portion.

In this case, the branch light guide portion has a pair of outer surfaces facing outward in the third direction and opposite to each other in the third direction, and the light guide portion includes two first outer surfaces arranged in the same row in the third direction. Two holes, having two second holes located between both ends of the branch light guide in the extending direction of the branch light guide, one second hole of the two second holes, A non-through hole that is open on one outer surface of the pair of outer surfaces, and the other second hole of the two second holes is a non-through hole that is open on the other outer surface of the pair of outer surfaces. It is preferable.

According to the above configuration, since the two second holes arranged in the third direction are non-through holes, the light that reaches the two second holes in the light in the branch light guide portion is the second hole. It is divided into light reflected by the peripheral surface (flat portion) and light passing through the inner peripheral surface (flat portion) of the second hole. Then, the light that has passed through the inner peripheral surface (flat surface portion) of the second hole passes through the second hole and enters the branch light guide portion again from the inner peripheral surface (different flat surface portion) of the second hole. Further, since the portion between the two second holes is a substance having a light-transmitting property, some of the light in the branch light guide portion may pass through between the two second holes. As a result, the light passing between the two second holes, the light passing through the inner peripheral surface (flat surface portion) of the second hole, and the light reflected by the inner peripheral surface (flat surface portion) of the second hole are finally The light is emitted from the emitting portion toward the outside. Therefore, the emitting portion has a light emitting mode that is strong and weak depending on the place, and is highly decorative.

In these cases, the branch light guide portion has a pair of outer surfaces facing outward in the third direction and facing in opposite directions in the third direction, and the second hole has a pair of facing in opposite directions in the third direction. It may be a stepped hole that is open on any one of the outer surfaces of the above and becomes smaller from the one outer surface toward the other outer surface.

According to the above configuration, since the second hole is a stepped hole, the inner peripheral surface (flat surface portion) defining the second hole is arranged differently in different positions in the third direction. As a result, the light having different passing positions in the branch light guide portion is dispersed (diffused) without the same behavior. Accordingly, the intensity of the light is added at the emission portion of the branch light guide portion, and the light emission is rich in decorativeness.

Further, as another aspect of the present invention, a plurality of light guide portions may be provided, the plurality of light guide portions may be arranged in a line, and the branched light guide portions of adjacent light guide portions may be continuous with each other.

According to the above configuration, when a plurality of LEDs are sequentially turned on, the continuous branch light guide portions continuously connect the light. Further, when a plurality of LEDs are turned on one after another, even if the emission colors of the LEDs are made different, the lights of different colors are exquisitely mixed in the continuous branch light guide portion. Therefore, the decoration by the light emitted from the emitting portion becomes good. Further, when a plurality of light sources are turned on at the same time, the light is integrated in the continuous branch light guide section, and the entire emission section of the decorative optical member (the continuous emission section of the plurality of light guide sections) emits light uniformly. To do.

In the first illumination unit 3 according to the present embodiment, when the light from the first light source (LED) 30 having a narrow light spread (high linearity) enters the light incident unit 311a, the light is emitted by the main light guiding unit 311. In the inside, it advances in the first direction and reaches the branch light guide portions 312 and 312 connected to the tip of the main light guide portion 311. Since the first holes 313 and 313 are present in the range A where the branch light guide portions 312 and 312 overlap with the main light guide portion 311 when viewed from the first direction, the light reaching the branch light guide portions 312 and 312 is The inner peripheral surfaces (flat surface portions 313a,...)

That constitute the inner peripheral surface thereof spread in the direction intersecting the first direction, the flat surface portion 314a, The light reflected by ... changes the directionality and reaches the fourth outer surfaces S7, S8, and the light that has passed through the flat surface portion 314a of the second hole 314 passes through the second hole 314 and is on another flat surface. .. enter the branch light guide portion 312.

Then, the light inside the branch light guide portion 312 is emitted from the emitting portion 312a (the other fourth outer surface S8) while being repeatedly reflected by the pair of fourth outer surfaces S7 and S8. In the present embodiment, the convex strips 312b and the concave strips 312c extending in the third direction are alternately formed on one of the fourth outer surfaces S7, so that the diffusibility of the light reflected by the one fourth outer surface S7 is improved. The light is high, and the light reaches the entire emitting portion 312a (the other fourth outer surface S8) of the branch light guide portion 312.

Therefore, the light of the first light source (LED) 30 entering from the light entering portion 311a of the main light guiding portion 311 spreads in a direction intersecting with the first direction without being concentrated, and the light of the pair of branch light guiding portions 312 and 312. The light is emitted from the emitting portion 312a.

In the present embodiment, since the first hole 313 and the second hole 314 are stepped holes, light having different passing positions in the branch light guide portion 312 does not have the same behavior and is dispersed (diffused).

Further, when the plurality of first light sources 30 are sequentially turned on, even if the emission colors of the respective first light sources 30,... Are changed, the light of different colors is exquisite in the continuous branch light guide portions 312 and 312. It mixes in the state. Therefore, the decoration by the light emitted from the emitting portion 312a becomes good. In addition, when the plurality of first light sources 30 are simultaneously turned on, light is integrated in the continuous branch light guide portions 312 and 312, and the emission portion 312a of the decorative optical member 31 (the plurality of light guide portions 310, 310, The entire emitting portions 312a,... Continuing with... Emit even light.

And a section 41. In addition, in the present embodiment, the second illumination unit 4 includes a cover body (hereinafter, referred to as a second cover body) 42 that covers the reflection surface 410 and the light emitting unit 40.

As described above, the light emitting section 40 is arranged at a position deeper than the display area 20 in the direction orthogonal to the display area 20 of the display section 2. That is, the light emitting unit 40 is arranged so as not to be located outside the display region 20 of the display unit 2 in the direction orthogonal to the display region 20. Based on this, the light emitting unit 40 is a light source (hereinafter, referred to as a second light source) 400 and an optical member 401 that covers the second light source 400, as shown in FIG. 13, and diffuses light from the second light source 400.

An LED is used as the second light source 400. In the present embodiment, the second light source 400 is a group of a plurality of LED chips having different emission colors (a plurality of LED chips mounted on the substrate). As a result, the second light source 400 causes the LED chips of different colors to sequentially emit light, emits a plurality of LED chips of different colors at the same time, or emits LED chips of a specified color. That is, the second light source 400 emits light in a designated decoration (light emission) mode by the LED chips of different colors.

In the present embodiment, the light emitting unit 40 is arranged along the entire length of the vertical bar 705b of the display unit 2. Accordingly, the light emitting section 40 includes a plurality of second light sources 400,.... The plurality of second light sources 400,... Are arranged at intervals in the extending direction of the vertical bar 705b. Each of the second light sources 400,...

The optical member 401 has optical transparency. In the present embodiment, the optical member 401 is made of semitransparent resin. The optical member 401 has an inner surface facing the second light source 400 and an outer surface opposite to the inner surface. In the present embodiment, many irregularities are formed on the inner surface of the optical member 401 for diffusing the light from the second light source 400. On the other hand, the outer surface of the optical member 401 is lens-cut.

Specifically, the optical member 401 has a first end in one direction and a second end opposite to the first end, and the first base portion 401a and the first base portion 401a in a direction orthogonal to the one direction. And a second base portion 401b on the opposite side. The first base 401a and the second base 401b are located on the same plane.

The optical member 401 is formed so as to be positioned outwardly from the first base 401a and the second base 401b toward the center, assuming that the first base 401a and the second base 401b are located on the same plane. Has been done. As a result, on the outer surface of the optical member 401, the center in the direction orthogonal to the one direction is most protruded, and on the inner surface of the optical member 401, the center in the direction orthogonal to the one direction is the most recessed. That is, the optical member 401 has a base portion (first base portion 401a and second base portion 401b) located on the rear side in the front-rear direction and a top portion located on the front side.

The optical member 401 is arranged such that one direction in which the first end and the second end are arranged is aligned with the extending direction of the vertical rail 705b, and the first base portion 401a and the second base portion 401b are supported by the frame 7. Based on this, the length of the optical member 401 in one direction corresponds to the length of the vertical bar 705b. Also,

The top of the optical member 401 is located between both ends of the reflecting surface 410 in the front-rear direction (between a front end 411 and a rear end 412 to be described later) when viewed in a direction orthogonal to the front-rear direction. Ie. The protrusion amount (the protrusion amount from the first base portion 401a and the second base portion 401b to the center of the outer surface) of the top portion (the most protruding portion) on the outer surface of the optical member 401 is set smaller than the width of the reflecting surface 410 in the front-rear direction. .. As a result, the light emitting unit 40 (optical member 401) makes the reflecting surface 410 visible when the calling device 1 is viewed from the direction orthogonal to the front-rear direction.

In the present embodiment, since the plurality of second light sources 400,... Are arranged at intervals, the optical member 401 is lens-cut for each region corresponding to the second light source 400. Further, on the outer surface of the optical member 401, a groove 401c extending in the circumferential direction is formed at a position (between lens cut regions) corresponding to between the adjacent second light sources 400 (see FIG. 12).

The optical member 401 having the above-described configuration has a plurality of second light sources 400,... Arranged along the vertical bars 705b, 705b of the display unit 2, with the first base 401a and the second base 401b supported by the frame 7. To cover all at once.

The reflection surface 410 of the wall portion 41 has a front end 411 along the outer edge of the display unit 2 and a rear end 412 located at a position deeper than the display region 20 in the direction orthogonal to the display region 20. That is, the reflective surface 410 faces outward in the direction in which the horizontal rails 705a, 705a of the frame 7 extend. In the present embodiment, the reflecting surface 410 is a mirror surface. The front end 411 of the reflecting surface 410 is along the vertical bars 705b and 705b of the frame 7 (first frame 70). The reflecting surface 410 is curved between the front end 411 and the rear end 412. That is, the reflecting surface 410 is a concave curved surface.

In the present embodiment, the rear end 412 of the reflecting surface 410 is located closer to the display area 20 than the front end 411 is. The rear end 412 of the reflecting surface 410 is in the same or substantially the same position as the bases 401a and 401b (the first base 401a and the second base 401b) of the optical member 401 when viewed from the direction orthogonal to the front-rear direction.

The second cover body 42 is light transmissive. The second cover body 42 covers the entire light emitting portion 40 and the wall portion 41. In the present embodiment, as described above, the second light source 400 employs a group of a plurality of LED chips having different emission colors (one in which a plurality of LED chips are mounted on the substrate). Along with this, the second cover body 42 is colorless and transparent in order to transmit the colored light from the second light source 400. In the present embodiment, the second cover body 42 is made of a colorless and transparent resin.

In the present embodiment, when the light emitting section 40 of the second illumination section 4 emits light, the light spreads from the light emitting section 40 as a base point. That is, the light from the light emitting unit 40 travels not only in the front side but also in the lateral direction. The second illumination unit 4 includes the wall portion 41 that is adjacent to the light emitting unit 40 and has the reflecting surface 410 that faces in the direction orthogonal to the front-back direction. The light traveling in the horizontal direction from the light emitting unit 40 reaches the reflecting surface 410 and is reflected by the reflecting surface 410. This causes the reflective surface 410 to appear shiny. In particular, since the reflective surface 410 has the front end 411 and the rear end 412 in the direction orthogonal to the display region 20, it looks as if the surface spreading in the depth direction emitted light. As a result, the presence of the lateral surfaces (reflection surfaces 410) on both sides of the display area 20 is highlighted. As a result, the front end 411 (edge) of the reflecting surface 410 becomes clear, and the existence of the display area 20 in the same row as that is also clear.

In particular, in the present embodiment, since the reflecting surface 410 of the second illuminating unit 4 is a curved surface, the reflected light is reflected not only in the lateral direction but also diagonally forward. As a result, the existence of the lateral surface on the front side of the display area 20 is clearly shown. As a result, the front end 411 (edge) of the reflecting surface 410 becomes clearer, and the presence of the display regions 20 in the same row as that is also clearer.

In the present embodiment, since the rear end 412 of the reflecting surface 410 is located closer to the center of the display area 20 than the front end 411, the light reflected by the reflecting surface 410 is prevented from proceeding to the display area 20 side.

As described above, the decorative optical member 31 employed in the first lighting unit 3 of the calling device 1 according to the present embodiment includes at least one light guide unit 310 formed of a material having a light transmitting property, The light guide part 310 is continuous with the light entrance part 311a that receives the light from the LED, the main light guide part 311 having a tip opposite to the light entrance part 311a in the first direction, and the tip of the main light guide part 311. The pair of branch light guide portions 312 and 312 extend in a second direction orthogonal to the first direction or in a direction including the second direction as a component, and the opposite side to the light incident portion 311a in the first direction. At least one of a pair of branch light guide portions 312, 312 having facing emission portions 312a and at least a part of the branch light guide portions 312, 312 positioned within a range A overlapping the main light guide portion 311 when viewed from the first direction. One first hole 313, and the first hole 313 extends in a third direction orthogonal to the first direction and the second direction, and has a polygonal shape when viewed from the third direction.

According to the decorative optical member 31 having the above-described configuration, since the light guide portion 310 is formed of a material having a light transmitting property, the light incident portion 311a of the main light guiding portion 311 has a narrow light spread (high linearity). ) When receiving the light from the LED, the light enters the main light guiding portion 311 from the light entering portion 311a and travels in the first direction. Along with this, the light that travels in the first direction in the main light guide 311 reaches the branch light guides 312 and 312 that are continuous with the tip of the main light guide 311. Since the light guide section 310 has at least one first hole 313, at least a part of which is located within the range A overlapping with the main light guide section 311 when viewed from the first direction in the branch light guide sections 312 and 312. The light reaching the branch light guide portions 312 and 312 reaches the inner peripheral surface of the first hole 313. Since the inner peripheral surface of the first hole 313 is the interface between the air layer and the substantial part of the branch light guide portion 312, the light reaching the inner peripheral surface of the first hole 313 is reflected by the flat surface portion 313a,. , And light that passes through the flat portions 313a,.

Since the first hole 313 extends in the third direction orthogonal to the first direction and the second direction and has a polygonal shape when viewed from the third direction, the two flat surface portions that form the inner peripheral surface of the first hole 313. 313a,... Spread in a direction intersecting the first direction. The light reflected by the inner peripheral surface (flat surface portion 313a,...) Does not return to the light incident portion 311a side, but is reflected in the branch light guide portions 312 and 312 in the direction intersecting the first direction. Further, the light that has passed through the inner peripheral surface (flat surface portion 313a,...) Of the first hole 313 passes through the first hole 313, and from the inner peripheral surface (different flat surface portion 313a,...) Of the first hole 313. It again enters the branch light guide portions 312 and 312.

Then, the light in the branch light guide portions 312, 312 reaches the emitting portion 312a of the branch light guide portions 312, 312 and the outer surface (fourth outer surface) S7 on the opposite side. Since the surfaces 312a and S7 are also interfaces between the air layer and the substantial parts of the branch light guide portions 312 and 312, the light reaching the emitting portion 312a and the outer surface (fourth outer surface) S7 is not the surface 312a, S7. It is divided into light reflected at S7 and light transmitted through the surfaces 312a and S7. That is, the light in the branch light guide portions 312 and 312 is emitted from the emitting portion 312a while being repeatedly reflected by the emitting portion 312a and the opposite surface (fourth outer surface) S7. As a result, the light from the first light source (LED) 30 spreads to the emitting portions 312a of the branch light guide portions 312 and 312 and is emitted to the outside.

In addition, in the present embodiment, the branch light guide portions 312 and 312 have a pair of outer surfaces (third outer surfaces) S5 and S6 facing outward in the third direction and opposite to each other in the third direction. The part 310 has two first holes 313 and 313 arranged in the same row in the third direction in the ends of the branch light guide parts 312 and 312 in the range A overlapping with the main light guide part 311 when viewed from the first direction. One of the two first holes 313, 313 has a first hole 313 which is opened at any one outer surface (third outer surface) S5 of the pair of outer surfaces (third outer surface) S5, S6. The other first hole 313 of the two first holes 313, 313 is a non-through hole, and the outer surface (third outer surface) S6 of either one of the pair of outer surfaces (third outer surface) S5, S6. It is a non-through hole opened at.

According to the above configuration, the two first holes 313 and 313 arranged in the third direction are non-penetrating holes, so that the two first holes 313 and 313 of the light in the branch light guide portions 312 and 312 are not passed through. The arriving light is divided into light reflected by the inner peripheral surface (flat surface portion 313a,...) And light passing through the inner peripheral surface (flat surface portion 313a,... ), and the inner peripheral surface of the first hole 313 (flat surface portion 313a). ,...) passes through the inside of the first hole 313, and enters the branch light guide portion 312 again from the inner peripheral surface (another flat surface portion 313a,...) Of the first hole 313. Further, since the space between the two first holes 313 and 313 is a light-transmissive substance, the light that passes through between the two first holes 313 and 313 of the light inside the branch light guide portions 312 and 312 is also included. is there. Thereby, the light that has passed between the two first holes 313 and 313, the light that has passed through the inner peripheral surface of the first hole 313 (the flat surface portion 313a,... ), and the inner peripheral surface of the first hole 313 (the flat surface portion 313a, The light reflected by () is finally emitted from the emitting portion 312a toward the outside. Therefore, the emitting portion 312a has a light emitting mode that is strong and weak depending on the place, and is highly decorative.

Further, in the present embodiment, the branch light guide portion 312 has outer surfaces (third outer surfaces) S5 and S6 that face outward in the third direction, and the first hole 313 extends in the third direction of the branch light guide portion 312. It is a stepped hole that is opened at outer surfaces (third outer surfaces) S5, S6 facing outward and becomes smaller from the outer surfaces (third outer surface) S5, S6 toward the inner side of the branch light guide portion 312.

According to the above configuration, since the first holes 313, 313 are stepped, the inner peripheral surfaces (planar portions 313a,...) Delimiting the first holes 313, 313 are arranged differently in different positions in the third direction. To As a result, in the branch light guide portion 312, the light beams passing through different positions are dispersed (diffused) without the same behavior. Therefore, the emission portion 312a of the branch light guide portion 312 has a strong and weak light, and emits light with rich decoration.

Further, the pair of branch light guides 312 and 312 are arranged in plane symmetry with respect to an imaginary plane passing through the center line of the main light guide 311 extending in the first direction.

According to the above configuration, the optical paths in each of the pair of branch light guide portions 312 and 312 become uniform. Therefore, as a result of the light from the first light source (LED) 30 being evenly dispersed into the pair of branch light guide portions 312 and 312, the emission portions 312a of the respective branch light guide portions 312 and 312 emit light uniformly.

In the present embodiment, the branch light guide portion 312 has an outer surface (fourth outer surface) S7 facing outward in the first direction, and an outer surface (fourth outer surface) S7 facing in a direction opposite to the emitting portion 312a, The outer surface (fourth outer surface) S7 is an uneven surface.

According to the above configuration, the light in the branch light guide portion 312 is diffused on the outer surface (fourth outer surface) S7 facing the direction opposite to the emitting portion 312a. Therefore, the light entering the branch light guide portion 312 is dispersed and reaches the emission portion 312a.

Including.

According to the above configuration, the convex stripes 312b and the concave stripes 312c make the outer surface (fourth outer surface) S7 facing the direction in which the light in the branching light guide portion 312 is opposite to the light emitting portion 312a, into an uneven surface. Since the convex strips 312b and the concave strips 312c extend in the third direction, each forms an outer surface facing the second direction or the direction including the second direction as a component. This makes it difficult for the light entering the branch light guide portion 312 to be diffused in a direction different from the extending direction of the branch light guide portion 312. That is, a large amount of light is guided to the emission portion 312a of the branch light guide portion 312.

In addition, in the present embodiment, the light guide unit 310 further includes at least one second hole 314 located between both ends of the branch light guide unit 312 in the extending direction of the branch light guide unit 312. 314 extends in the third direction and has a polygonal shape when viewed from the third direction.

According to the above configuration, the light entering the branch light guide unit 312 is repeatedly reflected by the (emission unit 312a and the opposite surface (fourth outer surface S7)), and the first light of the branch light guide unit 312 is detected. The inner peripheral surfaces of the two holes 314 and 314 are reached.

Since the inner peripheral surface of the second hole 314 is the interface between the air layer and the substantial parts of the branch light guide portions 312 and 312, the light reaching the inner peripheral surface of the second hole 314 has its flat surface portion 313a,.

Further, the light that has passed through the inner peripheral surface (flat surface portion 314a,...) Of the second hole 314 passes through the second hole 314, and from the inner peripheral surface (different flat surface portion 314a,...) Of the second hole 314. It again enters the branch light guide portion 312. Therefore, the light that has entered the branch light guide portion 312 is diffused due to the presence of the second hole 314, and a large amount of light is guided to the emission portion 312 a of the branch light guide portion 312.

In particular, the branch light guide portion 312 has a pair of outer surfaces facing outward in the third direction and opposite to each other in the third direction, and the light guide portion 310 includes two light guide portions 310 arranged in the same row in the third direction.

The arriving light is divided into light reflected by the inner peripheral surface (flat surface portion 314a,...) And light passing through the inner peripheral surface (flat surface portion 314a,... ), and the inner peripheral surface of the second hole 314 (flat surface portion 314a). ,...) passes through the inside of the second hole 314, and then enters the branch light guide portion 312 again from the inner peripheral surface of the second hole 314 (another flat surface portion 314a,... ). In addition, since the portion between the two second holes 314 and 314 is a substance having a light-transmitting property, some of the light in the branch light guide portion 312 may pass through between the two second holes 314 and 314. Thereby, the light that has passed between the two second holes 314 and 314, the light that has passed through the inner peripheral surfaces of the second holes 314 and 314 (the flat surface portions 314a,...) And the inner peripheral surface of the second holes 314 and 314 ( The light reflected by the plane portion 314a,... Is finally emitted from the emitting portion 312a toward the outside. Therefore, the emitting portion 312a has a light emitting mode that is strong and weak depending on the place, and is highly decorative.

Furthermore, the branch light guides 312 and 312 have outer surfaces (third outer surfaces) S5 and S6 that face outward in the third direction, and the second holes 314 and 314 define the third directions in the branch light guides 312 and 312.
