Description

  The present invention relates to an illumination device (or illumination structure) having a shelf structure (or display shelf structure) such as a showcase or a display shelf.

  In order to illuminate shelf boards such as display shelves of merchandise, fluorescent lamps are usually arranged along the longitudinal direction of the shelf boards. For example, in Japanese Patent Application Laid-Open No. 2006-346238 (Patent Document 1), an illumination lamp (fluorescent lamp) is attached to the front part of a shelf board of a product display shelf, and the front part of the shelf board and the front part of the illumination light are attached to the front part of the shelf board. An illuminating device having a translucent lighting cover with a U-shaped cross-section surrounding it is disclosed, and the front end of the lighting cover projects beyond the front end of the shelf board, so that the front, upper and lower sides of the shelf board can be illuminated. Are listed. However, in such an illuminating device, although a product arranged on a shelf board under the illuminating lamp can illuminate, it is necessary to use a fluorescent lamp with high power consumption. In addition, it is necessary to store the ballast of the fluorescent lamp, and wiring in the cover is also required, which makes the structure complicated and difficult to make a compact device.

  In JP 2003-275080 A (Patent Document 2), an illuminating lamp is attached to the lower surface of the front portion of the shelf board of the commodity display shelf, and a slit is provided in the shelf board directly above the illuminating lamp. There is disclosed a shelf illuminating device in which polarizing means (horizontal prism) that polarizes light irradiated upward from an illuminating lamp backward on the shelf is fitted from above. However, this apparatus not only requires the use of a fluorescent lamp with high power consumption, but also requires a horizontally long prism, which complicates the structure.

  It is also known to use a light emitting diode (LED) as a light source. Japanese Patent Laid-Open No. 2003-281908 (Patent Document 3) discloses an LED, a first lens that is installed on the light emission side of the LED and focuses and emits the light of the LED, and light emission of the first lens. There is disclosed an illumination device including a second lens that is disposed on the side and that radiates light emitted through the first lens by focusing the light into substantially parallel light. In this lighting device, by adopting a small LED with a small amount of heat generated by lighting as a light source, it is possible to illuminate for a long time, to be compact, and to radiate parallel light, and to read in the vehicle compartment It can be suitably used as a lamp. However, in this apparatus, since the irradiation angle of the LED is small, it is suitable for spot illumination, but it is difficult to illuminate a wide area. For this reason, when the illumination device is used to illuminate the bottom of the shelf, it is not suitable for illuminating the entire top surface of the shelf on which products are displayed.

  Japanese Patent Laying-Open No. 2007-287686 (Patent Document 4) is a shelf down lamp that is attached to the lower surface of the front edge portion of the upper shelf plate and illuminates the lower shelf plate, and includes a plurality of semiconductor light emitting elements on the substrate Light sources arranged side by side; extending in the direction in which the semiconductor light emitting elements are arranged, a light emitting surface, a light incident surface located behind the light emitting surface, a first reflecting surface, and a second light emitting surface A lower surface shelf, comprising: a reflective surface, wherein the light incident surface includes a first incident surface and a light distribution control member made of a translucent material formed by the second incident surface. And light that irradiates the lower part of the back wall surface connected to the rear side of the shelf, light that exits from the light exit surface substantially directly downward, and irradiates the upper surface of the lower shelf, and the light exit surface A shelf underlight is disclosed that illuminates substantially the entire area of the shelf on the lower side of the shelf from diagonally forward and upward with light emitted obliquely downward and rearward from . In such a device, even if there is a product on the lower shelf, it is difficult to see the shadow of the product from the front, and the light emitted from the light source is wasted even though it can be illuminated from diagonally forward. It can be used efficiently without lighting. In addition, since the semiconductor light emitting element is used as the light source, it is thin, and it is not necessary to incline the light source itself even though it is illuminated obliquely from above. Therefore, a thin device can be obtained. Patent Document 4 has a front cover portion that covers the light distribution control member from the front side, and a cover that is connected to the light distribution control member so that the front cover portion is on the front side of the shelf ( There is also disclosed a shelf lamp that is integrally formed of a light-transmitting synthetic resin and includes a cover whose front cover portion has a matte surface. Such a matte surface of the front cover part suppresses the light distribution control member and the like from being easily visually recognized, and suppresses the appearance of the shelf lamp from being deteriorated.

  However, in this apparatus, since the semiconductor light emitting element emits light with high directivity, in order to distribute the light from the semiconductor light emitting element, a light distribution control member having a complicated structure is required, and the structure of the illumination apparatus is also required. To be complicated. In addition, even if the product on the lower shelf can be illuminated, it cannot illuminate the upper, forward, or diagonally front of the shelf. For this reason, the illumination area is limited, and it is not possible to improve the effect of the products on the display shelf and the display effect.

JP 2006-346238 A (Claims) JP 2003-275080 A (Claims) JP 2003-281908 A (Claims, paragraph [0006]) JP 2007-287686 A (claims, paragraphs [0023] [0025])

The frame may include a frame main body that can be attached to a lower surface or a lower portion of the shelf board, and a cover member that can cover at least one of a front area, an upper area, and a lower area of the frame main body, A light emitting element array may be attachable to the frame body and / or the cover member. For example, the illuminating device of the present invention has a frame in which a light emitting element array can be attached to a lower surface or a lower part of a shelf plate, and a light transmitting part (or light transmitting area) is formed at least in a lower region of the light emitting element array. And a cover member that can be mounted on the frame and cover the light emitting element array, and can illuminate the light transmitting portion (or light transmitting area) by light emission from the light emitting element array.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a schematic exploded perspective view showing a shelf structure provided with the illumination device of the present invention, and FIG. 2 is a schematic sectional view showing an example of the illumination device of FIG. The display shelf shown in FIG. 1 and FIG. 2 includes support columns 1 positioned on both sides, locking slits 2 formed at predetermined intervals in the axial direction of the support columns, and a support base (not shown). And a shelf board 18 is installed between the support columns 1 and 1 with a shelf receiving member (or bracket) 3 at intervals in the vertical direction. That is, a claw-like hook 4 that can be locked to the locking slit 2 of the column 1 is formed at one end of the shelf receiving member 3, and the other end of the shelf receiving member 3 is illuminated. Between the frame main body 11 of the device (lighting unit) 10, the other end of the shelf support member 3 is engaged with the frame main body 11 of the lighting device (lighting unit) 10 to support or hold the frame main body 11. A holding mechanism is formed.

  As shown in FIG. 1, in this example, the holding mechanism is provided along a hole 5 formed at the other end of the shelf receiving member (or bracket) 3 and a guide 6 on the rear side wall 11 b of the frame body 11. A sliding member 7 slidable in the width direction, a convex portion 8 formed at the tip of the sliding member and fitable in the hole 5, and a side from the upper wall of the sliding member 7 A rotation restricting recess 9 having a U-shaped cross section is provided extending in a part direction and extending by a predetermined distance capable of accommodating the thickness of the shelf receiving member 3. In this holding mechanism, the shelf receiving member 3 is slid by inserting the convex portion 8 of the sliding member 7 into the hole 5 of the shelf receiving member 3 with the other end of the shelf receiving member 3 facing obliquely downward. When the other end of the shelf receiving member 3 is pivoted upward, the shelf receiving member 3 enters the rotation restricting recess 9 and the rotation is restricted. The upper wall (reversely concave wall) of the recess 9 can restrict the other end of the shelf receiving member 3 from rotating further upward about the protrusion 8. Therefore, the shelf receiving member 3 can be slidably attached in the width direction of the frame body 11 via the sliding member 7. The sliding member 7 can be fixed at an appropriate position on the guide 6 or the rear side wall of the frame body 11 with screws or the like.

  As shown in FIG. 2, the frame body 11 includes an upper wall 11a extending in the forward direction, a rear side wall 11b bent or suspended from the rear end portion of the upper wall, and an upper portion in the forward direction from the lower end portion of the rear side wall. A lower wall 11c extending shorter than the wall 11a is provided, and the guide 6 constituted by a pair of rails extending in the width direction of the frame body 11 is formed on the rear side wall.

  The frame main body 11 includes a substrate 12 provided with a light emitting element array 13 that is inclined slightly upward as it goes in the forward direction of the shelf board 18 (the direction opposite to the rear wall), and the light emitting diodes are arranged in a row. The mounting part (or mounting part) for mounting and the light emitting element array (or substrate) 13 are arranged in the back part (rear side wall side) of the shelf board 18 and can reflect the light from the light emitting element array 13. And a mounting portion for mounting a reflective member (orientation member) 14. Therefore, the light-emitting element array (or the light-emitting illumination area of the light-emitting element array) 13 can illuminate at least these areas directly toward the diagonally lower area or the lower area in front of the shelf board 18, and the reflecting member. 14 inclines toward the back of the shelf 18 as it goes upward, and can reflect the light from the light emitting element array 13 to at least the front or obliquely upward region.

  Further, a cover member 15 for covering the light emitting element array 13 is attached to the frame body 11, and this cover member extends in the forward direction from the front end portion of the upper wall of the frame body 11. The lighting hood (lighting casing) is formed. The cover member (or lighting hood) includes a transparent plate portion (transparent light-transmitting region) 16 formed in a lower region of the light emitting element array 13, and at least a front region or a front oblique upper region (from front to oblique upper portion). And a milky white cover plate portion (milky white light-transmitting region) 17 formed in the region. In this example, the milky white cover plate portion (milky white light-transmitting region) 17 is formed in a region from a front oblique lower region to a front oblique upper region.

  A mounting portion for mounting the cover member 15 (milky white cover plate portion 17) is formed on the upper wall 11a of the frame body 11, and the cover member 15 (transparent plate portion) is formed on the lower wall 11c. A mounting portion for mounting 16) is formed. The transparent plate portion 16 and the milky white cover plate portion 17 can be connected to each other by various mounting mechanisms such as slide fitting. In the vicinity of an appropriate portion of the frame main body 11 (for example, extending from the wall portions 11a, 11b, 11c and the cover member 15, the substrate 12 and the reflecting member 14 are mounted (for example, the cover member 15 of the upper wall 11a). In the vicinity of the mounting portion of the frame, for example, in order to provide flexibility and attach the frame body 11 and the cover member 15 to the side plate of the frame body 11, a groove having a U-shaped cross section or a droplet shape is used. (Or screw hole) 11d is formed.

  Further, the shelf receiving member 3 and the frame main body 11 are covered with a planar rectangular shelf 18. That is, on the shelf receiving member 3 and the frame main body 11, the shelf plate 18 is disposed in a state where the side wall of the lid-like shelf plate 18 is positioned and locked outside the side surface of the shelf receiving member 3. .

  In such an illuminating device, even if the irradiation angle of the light from the light emitting element array 13 is small, the light emitting element array 13 is oriented in a predetermined direction at the front portion of the shelf board 18, and the light emitting element is formed by the reflecting member 14. Since the light from the row 13 can be reflected at least in the forward or diagonally upper region, a wide range is illuminated through the transparent plate portion (transparent translucent region) 16 and the milky white cover plate portion (milky white translucent region) 17. it can. In addition, the product on the lower shelf can be illuminated with high brightness through the transparent plate portion (transparent light-transmitting region) 16, and the milky white cover plate portion (milk-white light-transmitting region) 17 is at least obliquely upward from the front. Indirect lighting can be performed while creating a soft and gentle atmosphere in the area leading to, and the product effect and value of the product can be enhanced. Also, if decoration units (decoration units such as letters, symbols, illustrations, etc.) are applied to appropriate places (front wall, etc.) in the translucent areas 16 and 17 (particularly the milky white translucent area 17), the above advantages are combined. In addition, the decorativeness can be further enhanced, and the value of the product can be improved by attracting the attention of buyers or consumers. In addition, the light from the light emitting element array 13 is not directly incident on the consumer's eyes, which is safe.

  In the present invention, as long as the shelf structure (showcase, display shelf, etc.) has a structure in which a plurality of shelf boards are arranged in multiple stages, the type and shape of each member forming the shelf structure are not particularly limited. In the shelf structure, shelves can usually be arranged in multiple stages with respect to the column, and can be attached to the column, a shelf receiving member (or bracket) that can be attached to this column, and a shelf receiving member (or bracket). In many cases, a simple lighting unit and a shelf board member (or a shelf board) that can be attached to or placed on the shelf receiving member are provided. The shelf receiving member (or bracket) may be adjustable in height position with respect to the column. As long as the shelf receiving member can support the shelf board, members having various structures can be used. For example, a bent support portion that is bent inward is formed at the lower end of the shelf receiving member on both sides, and the shelf supports the shelf receiving member. A state in which the side wall of the plate extends upward at a predetermined interval that allows the side wall of the plate to enter, a locking recess for locking the side wall of the shelf is formed, and the locking recess is locked to the side wall of the shelf Thus, the shelf receiving member may be supported by the bent support portion.

  The shelf board may be composed of a light transmissive member (for example, a glass plate, a resin plate, etc.) and a light shielding member (wood board, a metal plate, etc.), and as described above, a lid that covers the shelf receiving member, etc. You may comprise by a shaped member. At least a part (or all) of the shelf board may be made of a transparent light transmissive member or may be made of a milky white light transmissive member. If a shelf board is comprised with a light transmissive member, the goods on an upper shelf board can also be illuminated with the form of a cover member. Furthermore, an identification card or a display unit (electronically displaying the identifiers) that displays identifiers such as product names and prices of the products on the shelf plates along the longitudinal direction (width direction) is provided on the side wall on the front side of the shelf plates. A mounting portion to which a display unit or the like can be mounted may be formed.

  The lighting device of the present invention includes a light emitting element array, and can be attached to the lower surface or the lower portion of the shelf board. In addition, the lighting device and the shelf structure of the present invention include a frame that can be attached to a lower surface or a lower portion of a shelf plate (particularly, an end portion on the front side of the shelf plate), a light emitting element array that can be mounted in the frame, A translucent part formed on the frame. In addition, although a predetermined | prescribed translucent part or translucent area | region may be formed in a flame | frame, it is useful to use the cover member which has a translucent part or translucent area | region. That is, the frame is usually a frame main body that can be attached to a lower surface or a lower portion of a shelf board (in particular, an end portion on the front side of the shelf board), and at least one of a front area, an upper area, and a lower area of the frame body. One region may be configured with a cover member (or a lighting hood) that can cover, and a light transmitting portion or a light transmitting region may be formed in the cover member. A cover member (or lighting hood) can be attached to the frame body to cover the light emitting element array.

  In the lighting device, by attaching a cover member to the frame body, a lighting hood (lighting casing) that normally accommodates or covers the light emitting element array can be formed. The frame main body to which the cover member can be attached may be formed of plastic or the like, but is usually a light shielding member made of metal such as aluminum from the viewpoint of strength. Therefore, the frame main body is usually covered with a translucent cover member in a longitudinal cross-sectional shape according to the arrangement form of the light emitting element rows. For example, in order to illuminate the lower shelf board, the frame main body is in a form in which at least the lower region, preferably at least the lower region and the front region are translucent (a form having a translucent portion or an open portion in the region). It may be covered with a cover member.

  The cover member extends from the frame main body and has at least one region selected from the front region, the lower region, and the upper region (for example, the lower region and the front region, and the entire region of the front region, the lower region, and the upper region). It is translucent and the cover member may cover an appropriate position of the frame body, for example, at least the lower region, preferably at least the lower region and the front region. In order to expand the illuminable range, as shown in FIG. 1, the cover member includes an upper wall extending in a forward direction from an upper end portion (a front end portion of the upper wall) of the frame body, and an end portion of the upper wall. In many cases, it has a front side wall (front wall) bent downward from the front wall and a lower wall extending from the lower end of the front side wall to the lower end of the frame body (or the front end of the lower wall). Moreover, these wall parts of a cover member are often formed with a translucent member. In addition, the said cover member may be provided with the both-sides wall formed with the translucent member or the light-shielding member also in the both sides. In addition, a predetermined portion (for example, a lower region (translucent region) of the light emitting element array) of the cover member may be an open region that is opened without arranging a plate or the like if necessary.

  The cover member may be composed of a single member or a plurality of members. Moreover, what is necessary is just to form a translucent part (or translucent area) in at least 1 area | region among the front area of the flame | frame (or cover member), an upper area, and a lower area, and the case where it forms in at least a front area and a lower area. There may be many, and you may form in the whole area of a front area, an upper area, and a lower area. That is, the frame (or the cover member) may include a light transmitting portion in the front area, the upper area, and the lower area of the frame body. Further, the frame (or cover member or illumination hood) capable of covering the light emitting element array may include a light transmitting portion in at least a lower area of the light emitting element array, and at least a lower area and a front area of the light emitting element array. May be provided with a translucent part (or translucent area), or the whole may be a translucent part (or translucent area). With such a cover member, light does not directly enter the consumer's eyes, and safety can be improved while preventing eye fatigue. These light-transmitting regions may be transparent or translucent through which light from the light-emitting element can be transmitted. In order to form a soft and mild atmosphere by indirect lighting and enhance the effect of the product, it is advantageous that the cover member has a milky white light scattering portion (light scattering plate portion).

  In particular, in order to illuminate the lower shelf, the translucent area formed in the lower area of the light emitting element in the cover member may be a milky white translucent area (milky white plate portion), but transparent translucent. A region (transparent plate portion) is preferable.

  In addition, the translucent part formed in the front area may be a transparent translucent area (transparent plate part), but in order to diffuse light and make mild illumination, a milky white translucent area (milky white plate) Part). Furthermore, the milky white light transmission region can be formed in at least one region selected from the front region, the lower region, and the upper region, and is usually formed in at least the front region. For example, the milky white transparent region is at least in the front region and the front oblique upper region (particularly, the region from the front region to the front oblique upper region, particularly the region from the front oblique lower region to the front oblique upper region). It may be formed. The translucent part includes a transparent translucent part (or translucent area) formed in a lower area of the light emitting element and a milky white translucent part (or translucent area) formed in at least a front area or an oblique upper area in front. ).

  If decoration factors (decoration units such as letters, symbols, and illustrations) are applied to appropriate places (for example, the front wall or the front side wall) in a light-transmitting area (transparent light-transmitting area, milky white light-transmitting portion, etc.) , Attracting the attention of buyers or consumers, and further improving the product value.

  The transparent translucent area (or plate part) can be formed of a transparent member such as glass or transparent plastic (acrylic resin, polycarbonate resin, etc.), and the milky white translucent area (or plate part) is foamed resin or light scattering. It can be formed of a milky white member such as a resin (acrylic resin, polycarbonate resin, etc.) containing an agent (or light scattering factor). Further, the light-transmitting area (transparent or milky white light-transmitting area) may be colored more than necessary to further improve the lighting effect.

  By using the frame (or the frame main body), the light emitting element array can be easily attached to the lower surface or the lower portion of the shelf plate (particularly, the lower surface of the end portion on the front side of the shelf plate). The light emitting element array may be attached to the lower surface of the shelf board via a frame (or a frame body), or may be attached to the lower portion of the shelf board in the vicinity of the lower surface of the shelf board. Note that the frame is not limited to the above-described attachment structure, but may be attached to the shelf board using various attachment means, for example, an adhesive means such as a double-sided adhesive tape, a screw means such as a screw.

  As the light emitting element, various light emitting elements such as a semiconductor light emitting element (light emitting diode, laser diode, etc.), organic or inorganic EL (electroluminescence) can be used. The light emitting element array may be composed of a plurality of light emitting diodes mounted in a row on the substrate. In addition, the color temperature of the light emitting element can be selected according to the type of product placed on the display shelf, for example, daylight color, warm white (or reddish) daylight white, light bulb color (incandescent bulb color), etc. Also good.

  In order to illuminate a product arranged on a shelf board (for example, on a lower shelf board), it is advantageous that the irradiation angle of the light emitting element is wider. However, in the present invention, a light emitting element having a narrow irradiation angle may be used. The product arranged on the shelf board can be effectively illuminated. The irradiation angle by the light from the light emitting element may be about 90 to 150 ° (for example, 100 to 140 °, preferably 120 to 140 °). In particular, even a light emitting device having an irradiation angle of about 90 to 140 ° (for example, 120 °) can be expanded to about 150 to 220 ° (for example, 190 °) by using the alignment member. . The light emitting element rows can be selected according to the width of the shelf, and depending on the size of the shelf, a plurality of light emitting element rows may be formed on the substrate, or a plurality of substrates on which the light emitting element rows are arranged may be used. Further, if necessary, the light emitting element example may be formed of a plurality of light emitting elements having different light emitting directions.

  The light emitting element row can be attached or mounted in the frame (or the frame body and / or the cover member). The light emitting element array can be mounted at an appropriate position in the frame (for example, an upper part, a lower part, a front part, a rear part, and a corner part of the frame) according to the presence / absence of the orientation member and the arrangement form of the orientation member. More specifically, in addition to the upper part, lower part, rear part and corner part of the frame body, the front part of the cover member (upper or lower part on the front side), the rear part, the middle part between the front part and the rear part, the corner part An example of a light emitting element may be mounted on an upper part or a lower corner part on the front side or the rear side. The direction (or light emission direction) of the light emitting element array is not particularly limited as long as the shelf board can be illuminated in a wide range, and the front area (forward direction), upper area (diagonally upward, etc.), lower area of the frame (or frame body) (Such as diagonally below) and a rear area (backward direction). The direction (or light emitting direction) of the light emitting element array may be a downward direction (for example, a direction of a light transmitting part (or an open part) formed in at least a lower region of the light emitting element array in the frame body). In order to illuminate the product and the front of the shelf board, there are many cases in which the direction is obliquely downward toward the front, for example, the direction from the oblique lower area to the lower area in front of the shelf board. Furthermore, the direction (or light emission direction) of the light emitting element array may be the front direction, and may be the rear direction when using an alignment member.

  The alignment member is not necessarily required, but a wider range can be illuminated by using the alignment member. Therefore, in a preferred embodiment, the light emitting device array further includes an alignment member for directing light from the light emitting element array to at least a translucent part (for example, at least the lower direction and the front direction, and the front area, the upper area, and the lower area). ing.

  The orientation member has at least a predetermined direction of the shelf board (for example, at least one direction selected from the downward direction, the forward direction, and the upward direction, preferably at least the downward direction and the forward direction) according to the arrangement form of the light emitting element rows. In order to illuminate the light, it is sufficient that the light from the light-emitting element array can be directed at least in the direction of the light-transmitting portion or the light-transmitting region (for example, at least one direction selected from the downward direction, the forward direction, and the upward direction) You may illuminate the area | region of the diagonally upward direction ahead from the downward direction. The kind of the orientation member is not particularly limited as long as it has the above function, and one or a plurality of optical members (reflection members such as a reflecting mirror, refractive members such as a prism and a lens, etc.) disposed at appropriate positions in the frame. You may comprise.

  FIG. 3 is a schematic cross-sectional view showing another example of the illumination device of the present invention. In this example, the frame body 21 includes an upper wall 21a extending in the forward direction, a rear side wall 21b bent or hanging from the rear end portion of the upper wall, and a lower wall 21c extending in the forward direction from the lower end portion of the rear side wall. The length of the lower wall 21c in the forward direction is shorter than that of the upper wall 21a.

  On the upper part (upper wall 21a) in the frame, a substrate 22 having a light emitting element array 23 can be attached, and an attachment part having a flat surface in the lateral direction is formed. Further, a cover member 25 (milky white cover plate portion 27) for covering the light emitting element array 23 is attached to the frame body 21, and one end portion of the cover member is an end portion of the lower wall 21c. The transparent plate part 26 is mounted on the lower side of the light emitting element array 23, one end is mounted on the transparent plate part 26, and the other end is mounted on the end of the upper wall 21a. And a milky white cover plate portion 27 formed in a region extending from the front oblique lower region to the front oblique upper region. A reflective member (orientation member) 24 that can reflect light from the light emitting element array 23 can be attached to a front lower area in the cover member 25 (a lower area in front of the central axis of the light emitting element array 23). And the attachment site | part which has a flat surface in a horizontal direction is formed. That is, the substrate 22 provided with the light emitting element array 23 and the reflecting member 24 are located at a substantially parallel height, and the reflecting member 24 is located forward of the light emitting element array 23.

  In this example, of the light emitted from the light emitting element array 23, the light behind the light emission center can directly illuminate the transparent plate portion 26, and the light ahead of the light emission center passes through the reflecting member 24. The light can be reflected at least in a forward or obliquely upper region.

  In such an apparatus, even if the irradiation angle of the light from the light emitting element array 23 is small, the light of the light emitting element array is efficiently distributed to the front area and the lower area, and the transparent plate portion 26 and the milky white cover plate portion 27 are distributed. A wide range can be illuminated through.

  FIG. 4 is a schematic sectional view showing still another example of the illumination device of the present invention. This illuminating device is such that the translucent plate portion 36 mounted on the lower wall 31c of the frame body 31 has a longer length in the front-rear direction than the device of FIG. The configuration is the same as that shown in FIG. 3 except that it is tilted and attached in the direction 31a). Reference numeral 31b denotes a rear side wall.

  In this example, a light emitting element array 33 is mounted on the substrate 32 disposed on the upper wall 31a. Of the light emitted from the light emitting element array 33, the light downward from the light emission center and the light behind the light emission center are: The transparent plate portion 36 of the cover member 35 can be directly illuminated, and light in front of the light emission center can be reflected through the reflecting member 34 to the milky white cover plate portion 27, particularly at least the front or obliquely upper region. Yes, compared with the example of FIG. 3, the lower area of the front area can be illuminated. That is, in such an apparatus, the transparent plate part 26 and the milky white cover plate part 27 can be illuminated by the light emission of the light emitting element array 23, and in particular, the lower area of the milky white cover plate part 27 can also be illuminated.

  The position and angle of the reflecting member can be selected according to the illumination area (front area and / or lower area, etc.) in relation to the arrangement position of the light emitting element array, and the inclination in the arrangement form shown in FIG. The larger the angle, the lower the area can be illuminated. Contrary to the arrangement angle shown in FIG. 4, when the front portion of the reflecting member is raised, the upper area can be illuminated according to the inclination angle of the reflecting member. In addition to changing the inclination angle of the reflecting member, the inclination angle of the substrate including the light emitting element array may be changed, and a desired illumination region can be formed by adjusting these inclination angles. Further, when the light emitting element array and the reflecting member are positioned at the upper and lower parts of the frame, the position of the light emitting element example with respect to the reflecting member is adjusted using the relationship between the incident angle and the reflecting angle of the light with respect to the reflecting member. Thus, the intensity of illumination in the front area and the upper area can be controlled.

  In order to simplify the structure, the orientation member is composed of an inclined plate (A) to which the light emitting element array can be attached and whose upper part is inclined upward (or backward) as it goes in the forward direction of the shelf. May be.

  FIG. 5 is a schematic sectional view showing another example of the illumination device of the present invention. In this example, the frame body 41 includes an upper wall 41a that extends in the forward direction, a rear side wall 41b that bends or hangs from the rear end of the upper wall, and a lower wall 41c that extends in the forward direction from the lower end of the rear side wall. The length of the lower wall 41c in the forward direction is shorter than that of the upper wall 41a. An attachment part (or attachment part) to which an inclined plate 42 inclined upward as it goes in the forward direction (opposite to the rear wall) of the shelf board is formed in the inner part of the frame body 41. As the inclined plate 42, in this example, a substrate 42 including a light emitting element array 43 in which light emitting diodes are arranged in a row is used. The light emitting element array 43 is directed obliquely downward in the front.

  A cover member 45 is attached to the frame body 41. The cover member 45 includes a transparent light-transmitting area (transparent plate portion) 46 in the lower area and a milky white light-transmitting area (milk-white cover plate section) 47 in the front and front oblique upper and lower areas.

  Even in the illuminating device having such a structure, the lower shelf can be illuminated through the transparent plate portion 46 by the light emitting element array 43 facing obliquely downward in the front, and the front and front through the milky white cover plate portion 47. Can illuminate the diagonal upper and lower areas.

  As described above, the substrate may be used as an inclined plate, or a substrate including a light emitting element array may be attached to the inclined plate. The alignment member may be a member for directing light from the light emitting element array to at least the light transmitting section in order to illuminate the light transmitting section by light emission from the light emitting element array. May be configured with an inclined plate (for example, an inclined plate whose upper part is inclined forward or backward as it goes in the forward direction of the shelf). And a reflection member that can reflect the light from the light emitting element array, or may be configured by both the (A) inclined plate and the (B) reflection member. In order to effectively use the light from the light source for illumination, in a preferred embodiment, the alignment member is composed of a reflective member that reflects the light from the light emitting element array and directs it toward the light transmitting portion. The light from the light emitting element row may be directed in at least one direction selected from the lower direction, the front direction, and the upper direction (for example, at least the lower direction and the front direction), and the depth of the shelf board is more than the light emitting element row. You may comprise by the reflection member arrange | positioned by inclining in the back part direction of a shelf as it goes upwards. More specifically, an inclined plate whose upper portion is inclined upward (or rearward) as it goes in the forward direction of the shelf, and light from the light emitting element array that is inclined in the rear direction of the shelf as it goes upward. The orientation member may be configured by combining a reflecting member capable of reflecting at least a front region or an obliquely upper region. If necessary, the reflection member may include a variable reflection mechanism having a variable reflection angle. The orientation member is usually disposed along the longitudinal direction (or width direction) of the shelf board.

  The frame (frame main body and / or cover member) usually has an attachment site or a mounting site for mounting the orientation member. The mounting part can be formed at an appropriate position of the frame according to the type of the orientation member, the mounting part of the inclined plate (or the substrate) can be formed at the upper part of the frame, and the mounting part of the reflecting member is the back part of the frame (light emission). It can be formed in the back part) or the front part of the attachment part to which the substrate having the element row is attached.

  FIG. 6 is a schematic cross-sectional view showing still another example of the illumination device of the present invention. In this example, a substrate 52 provided with a light emitting element array 53 is attached to an upper portion of the frame main body 51 that can be attached to the lower surface of the shelf board. A wide light-transmitting portion (or an open portion) is formed in the lower region. Further, a translucent cover member (transparent plate portion or transparent translucent area) 56 capable of covering the light emitting element array 53 is attached to the translucent portion (or open portion) of the frame body 51. In such an apparatus, the light transmitting part (or the open part) of the frame main body 51 can be illuminated by the light emitted from the light emitting element array 53. Therefore, the lower shelf can be illuminated in a wide range through the wide translucent part (or open part) and the translucent cover member 56.

  Depending on the use of the shelf structure such as a display shelf and the luminance of the light emitting element, it may be necessary to illuminate a predetermined area of the shelf board (for example, the front side of the shelf board). FIG. 7 is a schematic sectional view showing another example of the illumination device of the present invention.

  In this example, a substrate 62 having a light emitting element array 63 is attached to a mounting portion having a flat surface in the lateral direction in an upper front region in the frame main body 61 that can be attached to the lower surface of the shelf board. A light-transmitting portion (open portion) that is narrower than the device shown in FIG. In addition, a translucent cover member (a transparent plate portion or a transparent translucent area) 66 capable of covering the light emitting element array 63 is attached to the translucent portion (open portion) of the frame body 61. In such an apparatus, light emitted from the light emitting element array 63 illuminates the light transmitting part (opening part) of the frame body 61, and the lower shelf is passed through the light transmitting part (opening part) and the light transmitting cover member 66. A predetermined area of the board, for example, an area on the front side of the shelf board can be illuminated in a wide range.

  As described above, in order to illuminate a wide range, the frame body is formed not only with the lower area but also with a translucent part (open part) at least in the front area, particularly in the oblique upper area from the lower area to the front. It is advantageous to do so. Further, as described above, it is advantageous to cover the translucent portion (open portion) (for example, the region excluding at least the lower region) with the cover member.

  The arrangement (position, orientation, etc.) of the light emitting element array and the alignment member (or reflecting member) can be selected relatively to each other, and the arrangement position (or mounting position) of the reflecting member is the same as that of the light emitting element example. It suffices if the translucent part can be illuminated with light from the light emitting element array in accordance with the arrangement form (position, orientation, etc.). The positional relationship between the light emitting element array and the reflecting member may be such that the light emitting element array is positioned or attached to the rear part (back part) of the frame and the reflecting member is located or attached to the front part (or front side) of the frame. The light emitting element array may be positioned or mounted on the front part of the frame (or the front part or the front side of the cover member), and the reflecting member may be positioned or mounted on the rear part or the back part of the frame. If the orientation member (or reflection member) is arranged at the rear part (back part) of the frame, the light to the front area, the lower area and the upper area is not shielded. The degree of freedom can be increased. Therefore, even if the orientation member (or the reflecting member) is a reflecting member having a flat reflecting surface or a curved reflecting surface, the reflecting member is directed in various directions with respect to the light emitting element array (or the emitted light beam). Can be arranged. The light emitting element row may be attached to an appropriate position (particularly in a region where illumination light is not shielded as much as possible) at the front portion of the frame (or the front portion of the cover member), or may be attached to the front portion, the lower portion, or the upper portion of the frame. When the light emitting element array is attached to the front part of the frame, in a preferred embodiment, the light emitting element array is attached to the front part (particularly, the front lower part or the lower corner part) of the frame (or cover member) that becomes a blind spot for the illumination of the product. Can be installed.

  FIG. 8 is a schematic cross-sectional view showing another example of the illumination device of the present invention. In this example, a mounting wall for mounting or mounting a plate-like reflecting member (reflecting mirror) 74 is erected at the back of the frame main body 71, and a cover member 75 is mounted on the frame main body 71. The cover member 75 includes an upper wall 75a extending from the upper end of the frame body 71, a lower wall 75b extending from the lower end of the frame body 71, and ends of the upper wall 75a and the lower wall 75b. Inclined walls 75c and 75d extending obliquely forward are provided. The cover member 75 is formed of a transparent or milky white member that can transmit light. A mounting portion 110 to which an identification card such as a product name and price can be attached is formed on the front surface of the inclined wall 75c on the upper side of the cover member 75, and light is emitted on the inner side of the inclined wall 75d on the lower side of the cover member 75. A mounting portion on which the substrate 72 including the element row 73 can be mounted is formed.

  In such an illuminating device, the upper wall 75a can be mainly illuminated with light from the light emitting element array 73 disposed on the inner side of the inclined wall 75d, and only the region of the upper wall 75a can be obtained using the reflecting member 74. In addition, the area (front area) of the lower wall 75b and the inclined walls 75c and 75d can also be illuminated.

  In the example of FIG. 8 described above, the mounting portion 110 to which the identification card can be mounted is formed in the cover member 75, but a front member provided with the mounting portion 110 may be provided as the cover member.

  FIG. 9 is a schematic cross-sectional view showing still another example of the illumination device of the present invention. In the lighting device of this example, not the inclined wall 85d of the cover member 85 that covers the frame body 81, but a mounting portion for mounting the substrate 82 including the light emitting element array 83 is formed on the lower wall 85b, and the inclined wall 85c. 8 is configured in the same manner as in FIG. 8 except that the identification card mounting portion is not formed. Even in such an illuminating device, the area (front area) of the upper wall 85a, the lower wall 85b, and the inclined walls 85c and 85d can be illuminated as in FIG.

  FIG. 10 is a schematic sectional view showing still another example of the illumination device of the present invention. The lighting device of this example includes a cover member 95 that can be attached to the frame main body 91 and a front member 141 that can be attached to the cover member. The cover member 95 is perpendicular to the upper wall 95a extending from the upper end of the frame body 91, the lower wall 95b extending from the lower end of the frame body 91, and the ends of the upper wall 95a and the lower wall 95b. And a front wall 95c extending in the direction. A mounting wall on which a flat reflecting member (reflecting mirror) 94 can be mounted is erected at the back of the frame main body 91, and a light emitting element is provided inside the lower portion of the front wall 95 c of the cover member 95. A mounting portion on which the substrate 92 including the rows 93 can be mounted is formed. The cover member 95 and the front member 141 can be formed of a transparent or milky white member that can transmit light. In this example, the cover member 95 is formed of a transparent member, and the front member 141 is formed of a milky white member.

  Furthermore, mounting portions to which both ends of the front member 141 can be mounted are formed at the upper wall 95a and the lower corner portion of the cover member 95. The front member 141 includes inclined portions 141a and 141b that are inclined forward from the upper and lower ends, respectively, and a mounting portion 110a to which an identification card can be mounted is formed on the upper inclined portion 141a. Note that a mounting portion 110b to which a suitable display card or shielding card can be mounted is formed on the lower inclined portion 141b.

  Even with such an illuminating device, the area (front area) of the upper wall 95a, the lower wall 95b, and the front wall 95c can be illuminated as in FIG. In particular, since the cover member 95 is formed of a transparent member, the region can be effectively illuminated over the entire area. In addition, since the front member 141 is formed of a milky white member, a mild or gentle atmosphere can be created and the lighting effect can be enhanced.

  Unlike the above example, the reflecting member is not limited to a flat reflecting member having a flat reflecting surface, but a reflecting member having a curved reflecting surface, for example, a concave reflecting surface whose central portion is recessed in the forward direction. It may be a reflecting member having a convex reflecting surface whose surface bulges toward the front direction (toward the front part of the cover member). Furthermore, the relationship between the height positions of the light emitting element array and the reflecting member (a flat reflecting member having a flat reflecting surface or a reflecting member having a curved reflecting surface) depends on the light emitting portion (or light emitting point) of the light emitting element array. The center point of the reflecting surface of the reflecting member may be located on the same height (same line or horizontal line) with respect to the height position, and the center point of the reflecting surface of the reflecting member (particularly the curved reflecting surface) is the upper part. Or you may be located in the lower part.

  FIG. 11 is a schematic cross-sectional view illustrating another example of the illumination device of the present invention. The lighting device of this example is different from the flat reflecting surface in FIG. 10 except that the reflecting member 104 has a curved curved reflecting surface that is curved with the surface bulging toward the front direction of the cover member 105. The basic configuration is common to the device. That is, the cover member 105 that can be attached to the frame main body 101 includes an upper wall extending from the upper end of the frame main body 101, a lower wall extending from the lower end of the frame main body 101, and ends of the upper and lower walls. The front member 141 can be attached to the cover member. In addition, a mounting portion on which the substrate 102 including the light emitting element array 103 can be mounted is formed inside the lower portion of the front wall of the cover member 105.

  A mounting wall on which a reflecting member (reflecting mirror) 104 having a convex reflecting surface (curved reflecting surface) that bulges and curves in the forward direction can be attached to the inner part of the frame body 101. . Further, the center point of the curved reflecting surface of the reflecting member 104 is located above the height position of the light emitting portion (or light emitting point) of the light emitting element array 103. The cover member 105 and the front member 141 can be formed of a transparent or milky white member that can transmit light. Also in this example, the cover member 105 is formed of a transparent member, and the front member 141 is formed of a milky white member.

  In such an illumination device, the light from the light emitting element array 103 can be reflected at a wide angle by the curved reflecting surface of the reflecting member 104. Therefore, not only the front area but also the upper and lower areas can be illuminated more effectively. In particular, light can be reflected over a wide area surrounded by a tangent line connecting the light emitting element array 103 to the upper part of the curved reflecting surface of the reflecting member 104 and a tangent line connecting the light emitting element array 103 to the lower part of the curved reflecting surface of the reflecting member 104. Can effectively illuminate the products on the shelf.

  FIG. 12 is a schematic cross-sectional view showing still another example of the illumination device of the present invention. The illumination device of this example is configured in the same manner as in FIG. 11 except that the degree of curvature of the convex reflecting surface of the reflecting member 114 is small (the radius is large). Even in such an apparatus, the light from the light emitting element array 113 mounted on the substrate 112 can be reflected in a wide angle forward by the convex reflecting surface of one reflecting member 114, and the cover member 115 mounted on the frame member 111. The front area, the upper area, and the lower area can be effectively illuminated.

  The degree of curvature (R) of the curved reflecting surface can be selected according to the desired illumination area. Moreover, the reflecting member (a reflecting member having a flat reflecting surface, a reflecting member having a curved reflecting surface) may have an uneven portion (an uneven portion having reflectivity) on the surface. The concavo-convex portion may have a cross-sectional shape such as a cone shape (conical shape, pyramid shape, etc.), a prismatic shape (such as a quadrangular prism shape), or a sawtooth shape. The concavo-convex portions may be formed linearly along the horizontal direction (longitudinal direction) at a predetermined interval in the vertical direction, or may be formed in the vertical and horizontal directions in the form of a lattice.

  FIG. 13 is a schematic cross-sectional view showing another example of the illumination device of the present invention. This illuminating device is the same as that of FIG. 11 except that the convex-shaped reflective surface (curved reflective surface) of the reflective member 124 has uneven portions (sawtooth-shaped reflective surfaces) 124a, 124b such as a sawtooth cross section. It is configured. In this example, since the light from the light emitting element array 123 mounted on the substrate 122 is preferentially reflected in a predetermined direction, the concave and convex portions 124a and 124b are subjected to curved reflection based on the incident angle of light with respect to the curved reflective surface. It is formed in a sawtooth shape at an appropriate position in the circumferential direction of the surface. In addition, the center point of the reflection surface (particularly, the curved reflection surface) of the reflection member 124 is located above the height position of the light emitting section (or light emission point) of the light emitting element array 123, and the reflection member 124 An uneven portion 124a is formed at a position higher than the center point of the reflecting surface (particularly the curved reflecting surface), and an uneven portion 124b is formed at a position lower than the center point of the reflecting surface (particularly the curved reflecting surface). That is, based on the relationship between the incident angle and the reflection angle of light from the light emitting element array 123, the notch angle and its direction of the serrated reflection surface, and the formation site of the serrated reflection surface are designed to enhance the illumination effect. Therefore, the light is preferentially reflected in the forward direction (front region) by the uneven portion (sawtooth-shaped reflective surface) 124a on the upper side of the curved reflective surface, and the uneven portion (sawtooth-shaped reflective surface) 124b on the lower side of the curved reflective surface. Therefore, in order to reflect light preferentially in the downward direction (downward region) and to suppress glare, the reflection of light in the diagonally upward front direction is suppressed.

  In such an apparatus, light from the light emitting element array 123 mounted on the substrate 122 can be reflected in a wide angle in the forward direction by the convex reflecting surface of one reflecting member 124. In particular, the uneven portions 124a and 124b can function as reflection angle adjusting elements, and light from the light emitting element array 123 can be preferentially reflected by the uneven portion 124a to the front area, and preferentially downward by the uneven portion 124b. Can be reflected. Therefore, it is possible to effectively illuminate the entire area of the front area and the lower area of the cover member 125 attached to the frame member 121, suppress the light reflection in the oblique front area of the upper area, make the product easier to see and fatigue the eyes. It is also possible to illuminate an oblique rear region of the upper region while suppressing the above.

  Note that the concavo-convex portion does not need to have a sawtooth shape in cross section, and may be a concavo-convex portion such as a cone as described above. Further, in the reflection angle adjusting element (such as a concave-convex portion having a sawtooth cross section), the notch angle and the direction of the sawtooth reflection surface are determined according to the desired reflection region based on the incident angle of light from the light emitting element array 123. And may be the same or different in the circumferential direction (upper and lower circumferential surfaces). Moreover, the formation part of an uneven | corrugated | grooved part (sawtooth-shaped reflective surface) is a part of the circumferential direction (periphery surface of an up-down direction) area | region of the reflective member into which light injects according to the incident angle and desired illumination area of light. It may be formed continuously or intermittently in the region, or may be formed in the entire region where light enters. For example, the reflection angle adjustment element has the same height position (or top region) as the center point of the reflection surface (particularly the curved reflection surface) of the reflection member, a first position (or region) higher than the center point, and a lower first point. You may form in the at least 1 position (or area | region) selected from 2 positions (or area | regions), for example, a 1st position (area | region) and a 2nd position (area | region). When the reflection area is adjusted by a reflection angle adjusting element (such as a concave / convex portion having a sawtooth cross section), light from the light emitting element array is reflected with priority in a predetermined direction, and the predetermined area can be effectively illuminated, and light is irradiated to an unfavorable area. It is possible to effectively prevent reflection. In a preferred embodiment, it is effective to reflect and illuminate with a reflection angle adjusting element (such as a concave-convex portion having a sawtooth cross-section) with priority on at least the front region, particularly at least the front region and the lower region.

  The reflection angle adjustment element can be formed at an appropriate position on the reflection surface in order to reflect in a predetermined direction. For example, the reflection angle adjustment element for reflection in the forward direction (front area), the reflection in the downward direction (lower area). For example, a reflection angle adjustment element for reflecting upward (upward), and a combination thereof (that is, a plurality of reflection angle adjustment elements). Further, the reflection angle adjustment element is not limited to a curved reflecting surface of a reflecting member (for example, a convex reflecting member), but is also a flat reflecting surface (for example, a reflecting surface of a flat reflecting member, particularly an inclined flat reflecting member). It may be formed on the reflective surface) or on the entire or part of the reflective surface.

  Further, the reflecting member having a curved reflecting surface adjusts the height position and direction (tilt, etc.) of the center (center axis) of the curved reflecting surface of the reflecting member with respect to the light emitting element array (or emitted light beam) to reflect light. The area may be adjusted.

  FIG. 14 is a schematic cross-sectional view showing still another example of the illumination device of the present invention. In this illuminating device, an extended reflecting portion (reflecting angle adjusting element for reflecting downward) 134c extending obliquely upward from the upper part of the curved reflecting surface of the reflecting member 134 is formed. Except for this point, the configuration is the same as in FIG. In this example, the light from the light emitting element array 133 mounted on the substrate 132 is forward (front region) by an uneven portion (sawtooth reflective surface, first reflection angle adjustment element) 134a on the upper side of the curved reflective surface. The light is preferentially reflected, and the light is preferentially reflected in the downward direction (lower region) by the uneven portion (sawtooth-like reflective surface, first reflection angle adjusting element) 134b on the lower side of the curved reflective surface. it can. Furthermore, the extended reflection portion (third reflection angle adjustment element) 134c preferentially reflects light reaching the rear obliquely upward direction downward. Therefore, the cover member 135 mounted on the frame member 131 can be illuminated with preferentially increased brightness in the lower direction (lower area) and forward direction (front area), and the light is reflected upward including the diagonally upward direction. Can suppress glare, make the product easier to see and suppress eye fatigue.

  The extended reflecting portion is not limited to the arcuate curved reflecting surface, and may have a flat reflecting surface. Further, the extended reflecting portion may be formed at an appropriate position in the circumferential direction of the curved reflecting surface based on the incident angle of the light with respect to the curved reflecting surface to adjust the light reflecting region. Furthermore, the extended reflection portion can be formed on an alignment member (a plate on which a light emitting element array can be mounted, a reflection member having a flat reflection surface or a curved reflection surface, etc.), and one alignment member (or reflection member) Not only the extended reflection part, but a plurality of extended reflection parts may be formed.

  The front member is not always necessary. Further, the front member does not need to include an inclined portion inclined in the forward direction, and may have a curved surface that bulges or curves in the forward direction.

  In the present invention, since illumination is performed using a light-emitting element array such as a light-emitting diode, a compact (for example, thin) illumination device with low energy consumption and long life can be formed. In addition, the lighting device and the shelf structure of the present invention can illuminate a wide range despite the use of the light emitting element, and can enhance the lighting effect by the cover member. Therefore, it is useful for illuminating a shelf structure (or display shelf structure) such as a showcase or a display shelf to increase the commercial value on the shelf board.
