  FIG. 1 is a perspective view of an indirect lighting device 1 according to an embodiment of the present invention. The indirect lighting device 1 includes a device main body 100 and a cover member 200 as an action body.

  As shown in FIGS. 2 and 3, the apparatus main body 100 includes a rectangular column-shaped long base material 110 and a light source unit 120 arranged in parallel with the base material 110 in the length direction of the base material 110. Yes. The light source unit 120 is connected to the base 110 by a link mechanism so that the position of the light source unit 120 can be changed in the circumferential direction of the base 110 and the direction of the light source unit 120 can be changed.

  That is, the base end portions of the two crank-shaped arm members 130 and 130 are connected to both end surfaces of the base material 110 in the length direction by screws 131 so as to be rotatable with respect to the base material 110. . Further, a long hole 132 is formed at the tip of each arm member 130, 130, and both ends of the light source unit 120 in the length direction of the light source unit 120 are connected to both arms 130, 130 by screws 133 inserted through the long holes 132. The distance from the base 110 is adjustable by the length of the long hole 132 so as to be rotatable relative to the base 110. Therefore, the position of the light source unit 120 can be changed in the circumferential direction of the base material 110 by adjusting the rotational positions of the arms 130 and 130 with respect to the base material 110, and the rotational position of the light source unit 120 with respect to the both arms 130 and 130 is adjusted. Thus, the direction of the light source unit 120 can be changed.

  It should be noted that only the adjustment of the rotational position of both arms 130 and 130 relative to the base material 110 or the adjustment of the rotational position of the light source unit 120 relative to both arms 130 and 130 is possible. The units 120 may be connected.

  In the light source unit 120, a large number of point light sources 121 are arranged in a line at regular intervals along the length direction. As these point light sources 121, LEDs (light emitting diodes) having directivity are used in this embodiment, but are not limited to LEDs. Further, the point light sources 121 may be arranged not in a single line but in a plurality of lines in which two or three or more light sources are arranged in the width direction of the light source unit 120.

  Each point light source 121 is supplied with electric power from a commercial power source via a power supply circuit and a control circuit (not shown) built in the base 110 and emits light. In addition, the point light sources 121 may be configured to be toned or dimmed as necessary.

  As shown in FIG. 3C, screw insertion holes 111 penetrating the base material 110 in the thickness direction are formed at both ends and the center portion of the base material 110 in the length direction, and the indirect lighting device 1 is attached. At the time of construction, the apparatus main body 100 is screwed and fixed to a mounted portion such as an indoor wall surface (including a ceiling surface or a floor surface) by a screw 112 or the like inserted through the screw insertion hole 111. 2 and 3 is a reinforcing member that is disposed on the upper surface of the base material 110 and protects and reinforces the base material 110.

  On the other hand, the cover member 200 shown in FIGS. 1, 4, and 5 is made of a molded body made of resin or metal and has a length slightly longer than that of the apparatus main body 100. As shown in FIG. 5, the cover member 200 is formed in an arc shape in which one corner is right-angled and the other corner is outwardly convex in the cross section, and the apparatus main body 100 can be accommodated therein. An inverted U-shaped cover member body 202 having a hollow portion 201 of a size, mounting flanges 203 and 204 extending horizontally outward from each lower end edge of the cover member body 202, and the cover member body 202 At both ends in the length direction, lid pieces 205 and 205 (shown in FIGS. 1 and 4) for closing the hollow portion 201 are provided.

  Each of the attachment flanges 203 and 204 is for attaching the cover member 200 to an attachment portion such as an indoor wall surface in a mode of covering the apparatus main body 100 when the indirect lighting device 1 is installed. Screw holes 203a and 204a are provided at both ends and the center.

  That is, when mounting the indirect lighting device 1, the cover member 200 is placed on the device main body 100 from the outside so that the device main body 100 attached to the attached portion is accommodated in the hollow portion 201 of the cover member 200. Then, the cover member 200 is attached to the attachment portion by screwing a screw or the like into the attachment portion through the screw holes 203a and 204a of the attachment flanges 203 and 204.

  The cover member 200 is formed with a slit 206 and a light-shielding portion 207 that form a light-transmitting / light-shielding region over almost the entire length thereof. That is, a slit 206 extending along the curved surface of the curved portion 209 is formed in the arc-shaped curved portion 209 formed at one corner in the cross section of the cover member main body 202. Many are formed at predetermined intervals over the entire area. These slits 206 transmit light emitted from each point light source 121 of the light source unit 120. On the other hand, between the slits 206, a large number of light-shielding portions 207 that block the light emitted from the point light sources 121 are formed across the width of the slits 206.

  In this embodiment, in the length direction of the cover member 200 (the arrangement direction of the point light sources 121), the width of each slit 206 is set to be substantially the same in all the slits 206, but in the length direction of the cover member 200, The width of the slit 206 may be changed regularly or irregularly. On the other hand, in the length direction of the cover member 200 (the direction in which the point light sources are arranged), the width of each light shielding portion 207 is set to be substantially the same in all the light shielding portions 207. The width of the part 207 may be changed regularly or irregularly.

  Moreover, it is good also as a structure by which the space | interval of a slit and the space | interval of each point light source 121 are matched, and each point light source 121 is arrange | positioned directly under a slit.

  Next, the attachment method and usage method of the indirect illumination device 1 shown in FIGS.

  As shown in FIG. 6, for example, after attaching the apparatus main body 100 turned upside down to the attachment portion 300 formed on the ceiling surface of the room via a screw 112 (shown in FIG. 3C), The cover member 200 turned upside down is arranged so that the slit 206 of the cover member main body 202 faces the indoor wall surface side, which is the illuminated surface 400, and the apparatus main body 100 is accommodated in the hollow portion 201 of the cover member main body 202. Next, the apparatus main body 100 is covered from the outside (below). In this state, the cover member 200 is fixed by screwing the screws 208 and 208 into the attachment member 300 through the screw holes 203a and 204a of the attachment flanges 203 and 204, respectively. Before attaching the cover member 200, the arms 130 and 130 of the apparatus main body 100 are rotated as necessary, and the light source unit 120 is rotated with respect to the arms 130 and 130, so that each point of the light source unit 120 is rotated. The position and orientation of the light source unit 120 are appropriately adjusted so that the direction of light emitted from the light source 121 matches the direction of the slit 206 of the cover member 200.

  When each point light source 121 is turned on after the indirect lighting device 1 is attached, a part of the light radiated obliquely downward from each point light source 121 toward the illuminated surface 400 passes through many slits 206 and is illuminated. The light is distributed to 400, and a part thereof is blocked by a large number of light blocking portions 207. In this embodiment, since the light source is a plurality of point light sources, light from one point light source 121 is mainly emitted from the slit 206 located in the immediate vicinity of the point light source 121 to the illuminated surface 400. For this reason, compared to a light source that emits light like a rod-shaped light source, a bright portion formed on the illuminated surface 400 by light transmitted through the slit 206 and a light shielding portion 207 form the illuminated surface 400 by blocking the light. The contrast with the dark part is increased, and a light pattern in which the bright part and the dark part are clearly drawn appears on the illuminated surface 400. This light pattern creates a fantastic atmosphere and enhances the production effect. be able to. In particular, in this embodiment, since a directional light emitting diode is used as the point light source 121, a bright part and a dark part can be drawn more clearly and clearly.

  In addition, by changing the width of at least one of the slit 206 and the light-shielding part 207 regularly or irregularly, the shape, position, combination, etc. of the bright and dark parts of the light pattern change, making it more original and directing A highly effective light pattern can be formed.

  In the example of FIG. 6, the case where the indirect lighting device 1 is installed on the ceiling surface of the room is shown. However, the installation location and the illuminated surface are not limited. For example, as shown in FIG. You may attach to the to-be-attached part 300 formed. In this case, a part of the light emitted obliquely upward from each point light source 121 toward the illuminated surface 400 passes through the many slits 206 of the cover member main body 202 and is distributed to the illuminated surface 400. Install.

  FIG. 8 is a perspective view of an indirect illumination device 10 according to another embodiment of the present invention. In this embodiment, an optical path changing region that changes the optical path of light emitted from each point light source 121 is formed in the operating body, and the optical path changing region reflects the light emitted from each point light source 121. It shows the case of.

  The indirect lighting device 10 includes a device main body 100 having a point light source 121 and a reflection unit 500. In addition, since the apparatus main body 100 is the same as that of embodiment shown in FIGS. 1-7, the same code | symbol is attached | subjected to the same component and description is abbreviate | omitted.

  The reflection unit 500 is formed to have substantially the same length as the apparatus main body 100, and includes a support body 510 and a reflection member 520 as an action body supported by the support body 510.

  As shown in detail in FIGS. 9 to 12, the support 510 has a flat plate-like support plate portion 511 that supports the reflecting member 520 and first leg portions that are connected to both end edges in the width direction of the support plate portion 511. 512 and a second leg 513.

  The first leg portion 512 extends vertically from one end edge in the width direction of the support plate portion 511, and extends horizontally at a right angle from the lower end edge of the vertical portion 512a to the opposite side of the support plate portion 511. And a horizontal portion 512b. The horizontal portion 512b is a flange for attaching the reflection unit 500 to an attached portion such as a ceiling, and has screw holes 514 (shown in FIG. 10A) at a plurality of locations in the length direction.

  The second leg portion 513 extends vertically from the other end edge in the width direction of the support plate portion 511 and extends vertically from the lower end edge of the vertical portion 513a to the opposite side of the support plate portion 511. The lateral portion 513b and a folded portion 513c partially folded upward at a right angle from a part of the edge of the lateral portion 513b. The horizontal part 513b is a flange for attaching the reflection unit 500 to an attached part such as a ceiling, like the horizontal part 512b of the first leg part 512, and has screw holes 514 at a plurality of positions in the length direction. Yes.

  Further, as shown in FIG. 12, the folded portion 513 c causes the side surface of the base 110 of the apparatus main body 100 to contact the outer surface of the folded portion 513 c when the indirect lighting device 10 is attached to the attached portion. It plays a role of positioning the apparatus main body 100 and the reflection unit 500. Note that the locking pieces 513d and 513d folded back diagonally upward from both ends in the length direction of the edge of the horizontal portion 513b are the lengths of the base 110 of the device main body 100 when the indirect lighting device 10 is attached. By locking both end surfaces in the vertical direction to the locking pieces 513d, the device main body 100 and the reflection unit 500 are positioned in the length direction.

  In this embodiment, as shown in detail in FIGS. 11 and 12, the height of the vertical portion 512a of the first leg portion 512 is set to be larger than the height of the vertical portion 513a of the second leg portion 513. Accordingly, the support plate portion 511 is inclined toward the second leg portion 513 side, that is, toward the apparatus main body 100 side that is disposed in contact with the folded portion 513c of the second leg portion 513. Accordingly, the reflection member 520 supported by the support plate portion 511 is also inclined and arranged on the apparatus main body 100 side. Due to the inclined arrangement of the reflecting member 520, the light from each point light source 121 provided in the apparatus main body 100 is efficiently distributed to the illuminated surface.

  As shown in FIGS. 8 to 10, the reflecting member 520 supported by the support plate portion 511 has a longitudinal direction in which a plurality of members having an arcuate shape with a downward cross section and excellent reflection characteristics are arranged in the length direction (alignment direction of the point light sources 121). And the surface is a reflective surface. Therefore, the shape of the reflection surface has a regular change shape in which a plurality of concave portions 521 having a circular arc in the longitudinal section are continuously repeated in the length direction (the direction in which the point light sources 121 are arranged). . In addition, the reflecting member 520 is fixed to the support plate portion 511 by two screws 522 at the bottom of each concave surface portion 521 at two locations in the width direction, whereby the support 510 and the reflecting member 520 are integrally connected. Yes.

  Next, a method for mounting and using the indirect lighting device 10 shown in FIGS. 8 to 12 will be described.

  As shown in FIG. 13, for example, in the reflection unit 500 in which the apparatus main body 100 which is turned upside down is first attached to the attached portion 300 formed on the ceiling surface of the room via a screw 112 and then turned upside down. The folded portion 513c of the second leg portion 513 is brought into contact with the side surface of the apparatus main body 100, and the engaging portions 513d of the second leg portion 513 are engaged with both end surfaces of the base body 110 of the apparatus main body 100 in the length direction. The reflection unit 500 is attached to the attached part 300 by screwing the horizontal part 512b of the first leg part 512 and the horizontal part 513b of the second leg part 513 with screws 530 in the arrangement described above. In addition, in order that the light from each point light source 121 reflected by the concave surface part 521 which is a reflective surface of the reflective member 520 is appropriately distributed to the wall surface which is the illuminated surface 400, the apparatus main body 100 and the reflective unit 500 The attachment position is set in advance. In addition, before attaching the apparatus main body 100 to the attached part 300, the reflection unit 500 may be attached to the attached part 300 first, and then the apparatus main body 100 may be attached to the attached part 300.

  After attaching the apparatus main body 100 and the reflection unit 500, the arms 130 and 130 of the apparatus main body 100 are rotated as necessary, and the light source unit 120 is rotated with respect to the arms 130 and 130. The position and orientation of the light source unit 120 are appropriately adjusted so that the direction of light emitted from the point light source 121 matches the direction of the concave surface portion 521 that is the reflection surface of the reflection member 520 in the reflection unit 500.

  When each point light source 121 is turned on in this state, the light emitted from each point light source 121 to the concave surface portion 521 that is the reflecting surface of the reflecting member 520 is reflected by the reflecting surface and distributed to the illuminated surface 400. The

  The amount of light reflected by the reflection member 520 of light from one point light source 121 depends on the distance between the point light source 121 and the reflection part of the reflection member 520, and becomes smaller as the part is farther away from the point light source 121. As a result, the amount of light reflected from each part of the reflecting surface of the reflecting member 520 by the many point light sources 121 is different, and a light pattern in which bright and dark parts are clearly drawn appears on the illuminated surface 400. Creates a fantastic atmosphere and enhances the production effect. In addition, in this embodiment, since the reflecting surface is formed by continuously forming a plurality of arc-shaped concave surface portions 521, the reflecting form is further complicated, and a light pattern in which the bright portion and the dark portion are intertwined more complicatedly. Appears and the production effect is further enhanced. Furthermore, in this embodiment, since a directional light emitting diode is used as the point light source 121, a bright part and a dark part can be drawn more clearly and clearly.

  Although the example of FIG. 13 shows the case where the indirect lighting device 10 is installed on the ceiling surface of the room, the installation location and the illuminated surface are not limited. For example, as shown in FIG. You may attach to the to-be-attached part 300 formed in the same. In this case, the apparatus main body 100 and the reflection unit 500 are attached so that the light emitted from each point light source 121 to the reflection member 520 and reflected obliquely upward by the reflection member 520 is distributed to the illuminated surface 400.

  In the embodiment of FIGS. 8 to 14, the case where the optical path changing region of the working body is the reflecting region of the reflecting member 520 is shown. However, the lens that refracts the light from each point light source 121 in the optical path changing region of the working body. You may comprise by.

  FIG. 15 shows an indirect illumination device 11 using such a lens 600. In the indirect illumination device 11, a plate-like or rod-like lens 600 that is long in one direction and changes the optical path of light from each point light source 121 by refraction between each point light source 121 of the device main body 100 and the illuminated surface. The point light sources 121 are arranged along the arrangement direction. The lens 600 can also form a light pattern in which a bright part and a dark part are mixed on the surface to be illuminated, as in the case of the reflecting member 520. For example, by adjusting the refractive index of the lens 600 so as to collect the light from the point light source radiated into the range for each predetermined range in the length direction of the lens 600 (the arrangement direction of the point light sources), Form a light pattern where the condensing part becomes a bright part and a dark part between the condensing parts, or by changing the refractive index of the lens 600 every predetermined range or continuously. Can do.
