Furthermore, the glare 26 is a flat plate shape having translucency, and is fitted in a concave groove 23b formed at the opening end of the aluminum case 23 to protect the LED 25 and the like housed in the aluminum case 23. Yes. Further, a radiator 23c having fins composed of a plurality of protrusions is provided on the outer surface of the aluminum case 23 so that heat generated in the aluminum case 23 due to illumination of the LED 25 can be dissipated. In addition, it is not always necessary to employ an aluminum case as the lighting case, and it may be a case made of metal or resin of other materials.

  As described above, the front illumination device 14 is composed of a structural member such as the aluminum case 23 and the LED 25 housed in the aluminum case 23, and the vertical dimension B of the front illumination device 14 is that of the aluminum case 23. It is a direction dimension, and the vertical dimension B is formed shorter than the vertical dimension A of the shelf 6.

  Next, attachment of the front illumination device 14 to the shelf board 6 will be described. The front illumination device 14 is attached to the front surface of the bottom surface of the shelf board 6, that is, the front side of the reinforcing plate 18, with a predetermined inclination with respect to the shelf board 6 as described later.

  More specifically, a blocking material 32 that closes the left and right ends of the aluminum case 23 that accommodates the LEDs 25 and the like is attached by fixing screws 30, and the support plate 22 that is fixed to the reinforcing plate 18 by the fixing screws 20 is blocked. The contact portion 22b formed in the upper portion is in contact with the lower surface of the flat plate portion 6a of the shelf board 6 and extends forward so as to be close to the material 32. The cylindrical shaft body 33 is inserted into the insertion hole 32a formed in the closing material 32 and the insertion hole 22a formed in the support plate 22 so as to have the same diameter as the insertion hole 32a. Insert through.

  That is, the front illumination device 14 is placed on the virtual rotation axis D that coincides with the center line of the LEDs 25 aligned in the width direction of the shelf 6 on the support plate 22 provided on the shelf 6 via the reinforcing plate 18. It is mounted via a certain shaft 33, is inclined so that the illumination direction of the LED 25 faces the rear lower side, and is provided to be rotatable around the shaft 33. Specifically, as shown in FIG. 3A, in the front illumination device 14, the outer surface of the aluminum case 23 is in contact with the mounting portion 18 a of the reinforcing plate 18, and the illumination direction from the LED 25 is most rearward. As shown in FIG. 3B, the outer surface of the aluminum case 23 is in contact with the fitting portion 19a of the display plate 19 so that the illumination direction from the LED 25 faces the most front side. It is provided to be movable.

  By doing in this way, the number of parts which attach the front illuminating device 14 is decreased, the effort and time for attaching the front illuminating device 14 to the shelf board 6 are omitted, and the front illuminating device 14 is a shaft body. The product display space S below the shelf board 6 can be illuminated in a wide range by being provided so as to be rotatable around 33.

  Thus, the degree of freedom of the illumination range of the front illumination device 14 can be increased by appropriately rotating the front illumination device 14 around the virtual rotation axis D passing through the center of the shaft body 33.

  In the present embodiment, as described above, the front illumination device 14 having the vertical dimension B smaller than the vertical dimension A of the shelf board 6 is provided so as to be inclined so that the illumination direction of the LED 25 faces the rear lower side. ing. By doing in this way, since the front illuminating device 14 in which the LED 25 is disposed can suppress a protruding portion protruding from the lower surface of the shelf board 6, the product in the product display space S below the shelf board 6 can be reduced. It is possible to illuminate the entire product display space S below without being in the way of taking in and out.

  The shaft body 33 is provided with insertion holes 33a having both ends communicating with each other, and a power cable 34 connected to each LED 25 and supplying power is inserted into the insertion holes 33a. By doing in this way, even when the front illumination device 14 is rotated with respect to the support plate 22, the power cable 34 inserted through the insertion hole 33 a of the shaft body 33 that hardly changes its position can be twisted. Therefore, the power cable 34 can be prevented from being damaged or leaked.

  Further, a protective cover 31 formed so as to cover the insertion hole 33a of the shaft body 33 from the outside is attached to the support plate 22. By doing so, the protection cover 31 is inserted into the insertion hole 33a of the shaft body 33. The power cable 34 can be protected by the protective cover 31 formed so as to cover the insertion hole 33a.

  The shaft body 33 does not necessarily have to be provided at both ends in the width direction of the front illumination device 14, and the illumination device rotates around one shaft body provided only at one end side in the width direction. It may be provided.

  Next, illumination by the front illumination device 14 will be described.

  As shown in FIGS. 3 (a) and 3 (b), the LED 25 accommodated in the aluminum case 23 is irradiated with light that is highly linear, and the light emitted from the LED 25 is light in a side view. The virtual center axis C is strongest and tends to become weaker as it spreads from the center axis C at predetermined light spread angles θ1 and θ2.

  By tilting the front illumination device 14 as described above, the central axis C of the light from the LED 25 is directed rearward and downward, and the side view shape of the aluminum case 23 to which the LED 25 is attached is slightly asymmetrical left and right. Thus, the light spread angle θ2 from the center axis C is formed smaller than the light spread angle θ1 from the center axis to the front side. Specifically, the light spreading angle θ1 on the front side from the central axis is set to about 45 degrees, and the light spreading angle θ2 on the rear side from the central axis is set to about 38 degrees smaller than 45 degrees.

  By doing in this way, the front illumination device 14 is compared with the front side of the product display space S below the shelf 6 that is relatively close to the front illumination device 14 provided on the front surface of the bottom surface of the shelf 6. The front illumination device 14 irradiates the rear side of the product display space S below the shelf 6 that is relatively far from the front illumination device 14 with a relatively large light beam. Therefore, the front illumination device 14 can illuminate the entire product display space S below the shelf 6 uniformly and in a wide range.

  Further, by using the shape of the aluminum case 23 as the lighting case, the light spreading angles θ1 and θ2 can be easily set.

  If the light spread angles θ1 and θ2 from the central axis C are formed so that the light spread angle θ2 on the rear side from the central axis C is smaller than the light spread angle θ1 on the front side from the central axis C. However, the light spread angle θ1 on the front side from the central axis C is not necessarily set to about 45 degrees, and the light spread angle θ2 on the rear side from the central axis is not necessarily set to about 38 degrees.

  Further, a reflecting plate 27 that reflects light is provided in the vicinity of the LED 25, and a part of the light that travels straight from the LED 25 is reflected by the reflecting plate 27 and irradiated toward the product display space S below the shelf 6. . As described above, the light from the LED 25 having a large linearity can be diffused over a required range with a simple configuration in which only the reflection plate 27 is provided.

  Next, the rear illumination device 44 will be described. Since the rear illumination device 44 of this embodiment has substantially the same structure as the front illumination device 14 in which a plurality of LEDs are arranged in the left-right direction, the same components are denoted by the same reference numerals. Therefore, detailed description here will be omitted.

  As shown in FIG. 4, locking members 41 and 41 for locking to the pair of left and right brackets 17 and 17 are formed on the left and right ends of the rear lighting device 44 so as to form the left and right ends of the rear lighting device 44. A screw 48 is screwed into a mounting hole formed in the end 44a.

  As shown in FIG. 5, the locking member 41 constituting the locking portion includes, for example, a metal plate, an upper plate 41 a that faces in the horizontal direction, and an inner plate 41 b that is suspended from the inner end of the upper plate 41 a. And an outer plate 41c suspended from the outer end portion of the upper plate 41a. The upper plate 41a is formed on the upper side of the radiator 53c located on the upper surface of the rear illumination device 44. It is attached to extend. The inner plate 41b is formed with an insertion hole through which a power cable 49 for supplying electric power connected to an LED (light emitting diode) provided in the rear illumination device 44 is inserted, and is directed from the inside to the outside through the insertion hole. Then, the power cable 49 is inserted.

  As shown in FIG. 6, engaging grooves 17b and 17b are formed in the upper end edges 17a and 17a of the brackets 17 and 17 as recesses into which the locking members 41 and 41 can be freely fitted. The rear illumination device 44 is attached to the brackets 17 and 17 by locking the upper plates 41a and 41a of the stop members 41 and 41 to the engagement grooves 17b and 17b.

  As shown in FIG. 5, the flat plate portion 6 a of the shelf plate 6 disposed above the bracket 17 in a state where the left and right locking members 41, 41 are locked in the engagement grooves 17 b of the left and right brackets 17, 17. A gap is provided between the lower surface of the rear lighting device 44 and the upper surface of the rear illumination device 44 (radiator 53c). For this reason, since the heat dissipation effect of the rear illumination device 44 is improved, the deterioration of the LED due to heat is prevented, and heat is not directly conducted to the shelf board 6, so that the products placed on the shelf board 6 can be prevented. There is no risk of hindering cooling.

  Furthermore, since a space is also formed between the inner surface of the brackets 17 and 17 and the outer surface of the inner plate 41a, not only can the power cable 49 and the like be inserted without interfering with the bracket 17, but also the side can be used for heat dissipation. Since a space is formed, the heat dissipation effect is further increased.

  In the present embodiment, the depth of the engagement groove 17b is longer than the thickness of the upper plate 41a of the locking members 41, 41, so that the upper surface of the upper plate 41a of the locking member 41 is increased. Does not protrude above the upper end edge 17a of the bracket 17, so that the shelf plate 6 is not hindered from being placed, and the shelf plate 6 is held at a predetermined angle by engagement with the engagement groove 17b. Even when tilted, the movement of the rear illumination device 44 relative to the bracket 17 can be prevented. Further, since the outer plates 41c, 41c of the left and right locking members 41, 41 are arranged on the outer surface side of the brackets 17, 17, the movement of the rear illumination device 44 in the left-right direction is also restricted.

  As described above, the rear illumination device 44 of the present embodiment is configured such that the rear illumination device 44 in which a plurality of LEDs are arranged in the left-right direction behind the front illumination device 14 on the lower surface of the shelf 6 is rear illumination. Since the locking members 41, 41 as locking portions provided outward from the left and right ends of the device 44 can be attached by being locked to the pair of left and right brackets 17, 17, only the front illumination device 14 can be attached. The product display space S on the rear side of the front illumination device 14 that becomes dark can be brightened, and the entire product display space S can be illuminated in a wide range by the rear illumination device 44.

  Further, the locking members 41 and 41 as locking portions provided outward from the left and right ends of the rear illumination device 44 are simply locked to the pair of left and right brackets 17 and 17 that support the shelf board 6. The rear illumination device 44 can be easily attached to the shelf board 6 and the like between the pair of left and right brackets 17 and 17 in a compact manner. Furthermore, by using LEDs (light emitting diodes), the vertical dimension of the rear illumination device itself can be made thinner than other illumination devices such as fluorescent lamps, so that the product display space below is not affected as much as possible. Not only can it be placed, it can also save electricity.

  Further, since the locking members 41 and 41 are structured to be detachably locked to the upper end edges 17a and 17a (engaging grooves 17b and 17b) of the brackets 17 and 17, The rear illumination device 44 can be easily installed only by locking the plates 41a, 41a to the upper end edges 17a, 17a of the brackets 17, 17, and the product display space S on the rear side of the front illumination device 14 can be provided. The rear illumination device 44 can be attached / removed depending on whether illumination is necessary.

  Further, since the engaging grooves 17b and 17b for fitting the locking members 41 and 41 are formed in the upper end edges 17a and 17a of the brackets 17 and 17, respectively, the engaging grooves 17b and 17b of the brackets 17 and 17 are formed in the engaging grooves 17b and 17b. The upper plates 41a, 41a of the locking members 41, 41 can be easily locked, and by this locking, the mounting position of the rear illumination device 44 with respect to the brackets 17, 17 can be easily determined, and Even when the shelf board 6 is inclined, the rear illumination device 44 can be prevented from moving relative to the brackets 17 and 17.
