  According to the present invention, in a showcase for displaying products on a shelf installed in a display room, an LED illumination device having LED elements is rotatably attached to the shelf and rotated, so that the product mounting surface of the shelf can be rotated. Since the state of irradiating light from the LED element upward and the state of irradiating light below the shelf can be selected, in the rotating state of the LED lighting device that irradiates light upward, the product mounting of the shelf is performed. The product placed and displayed on the placement surface can be illuminated from below. Moreover, in the rotation state of the LED illumination device that irradiates light downward, the products displayed below the shelf can be illuminated from above.

  As a result, various lighting effects can be given to the product from the LED lighting device attached to the shelf, and the product sales effect can be significantly improved. In particular, the LED lighting device is rotatably mounted on the shelf, and the illuminating angle can be changed from the upper side to the lower side only by rotating, so that the operability is remarkably improved.

  In addition, if the LED illumination device is turned off in a rotation state other than the state in which light is irradiated upward from the product placement surface of the shelf as in the invention of claim 2 and the state in which light is irradiated downward, When lighting from the shelf is unnecessary, the LED element can be stored between the product placement surface and the lower surface of the shelf and turned off, and the LED element of the LED lighting device is damaged by the product.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, 1 is a showcase of an embodiment, and this showcase 1 is an open showcase in which a main body is constituted by a heat insulating wall 2 whose front surface is open. A partition plate 3 is provided inside the heat insulating wall 2 with a space therebetween, and a display chamber 4 having an open front surface is formed in the partition plate 3, and is continuous between the partition plate 3 and the heat insulating wall 2. The duct 6 is configured. An evaporator 7 and a blower 8 of a cooling device (not shown) are arranged in the duct 6.

  Further, a cold air discharge port 11 communicating with the duct 6 is formed at the upper edge of the front opening of the display chamber 4, and a cold air suction port 12 is formed at the lower edge of the front opening of the display chamber 4, which communicates with the duct 6. Yes. Then, the cool air in the duct 6 that exchanges heat with the evaporator 7 is accelerated by the blower 8, discharged from the cool air discharge port 11 into the display chamber 4, and sucked from the cool air suction port 12. Thus, a cold air curtain is formed in the front opening of the display chamber 4 and a part thereof is circulated in the display chamber 4, and the display chamber 4 has a predetermined temperature (for example, a refrigeration temperature of + 5 ° C. to + 10 ° C.). ) Are cooled and displayed on products such as plastic bottle drinks and can drinks.

  In addition, shelves 14 are erected in the display room 4 in a plurality of stages (three stages in the embodiment), and products are placed on the product placement surface 14A on each shelf 14 and the deck pan 16 at the bottom of the display room 4. Displayed. A price rail 17 is attached to the front end of each shelf 14, and a guard 18 is provided between the price rail 17 and the shelf 14 to prevent the product from falling. The LED lighting devices 21 to which the present invention is applied are mounted in the respective shelves 14 on the rear side of the guard 18 from the rear side.

  The LED lighting device 21 according to the embodiment includes a main body 24 having a rectangular cross section having a length extending over substantially the entire width of the shelf 14, and an LED element 22 attached to one surface of the main body 24 over substantially the entire width in the longitudinal direction. It consists of and. The LED illumination device 21 is rotatable with respect to the shelf 14 around a rotation shaft 23 extending in the longitudinal direction about the center of the main body 24. The upper surface (product placement surface 14A) and the lower surface of the shelf 14 corresponding to the LED lighting device 21 are open.

  A cam 26 is attached to one end of the LED lighting device 21 in the longitudinal direction of the main body 24. In this cam 26, the outer surface 26A corresponding to the surface of the main body 24 provided with the LED element 22 and the surface on the opposite side thereof is flush with these surfaces, and the outer surface 26B other than the outer surface 26A is rotated. An arc shape centering on the shaft 23 is formed. The outer surface of the cam 26 changes in distance from the rotation shaft 23 according to the rotation angle, the center of the surface on which the LED element 22 is provided is the shortest, and gradually extends from there, and the outer surfaces 26A and 26B. The maximum is at the connection point, and the maximum remains throughout the entire outer surface 26B.

  That is, when the direction in which the LED element 22 is directed is 0 degree, the distance from the rotation shaft 23 to the outer surface 26B becomes the maximum at the rotation angle rotated 90 degrees and 270 degrees clockwise in FIG. It becomes the minimum at 180 degrees. A switch 27 is mounted in the shelf 14 on the rear side of the cam 26. The switch 27 is provided so as to be in contact with the outer surface of the cam 26. When the switch 27 contacts the outer surface 26B to close the contact of the switch 27 and the center of the outer surface 26A is on the switch 27 side, the switch 27 is The contact is opened away from 26A.

  And since this switch 27 is interposed in the electric circuit between the LED element 22 and the power source, it is lit by detecting that the LED element 22 is directed upward or downward by opening and closing the contact of the switch 27. Thus, it can be turned off by detecting that it has turned 90 degrees backward or forward. That is, the cam 26 and the switch 27 serve as means for detecting the orientation of the LED element 22.

  With the above configuration, when it is desired to illuminate the product on the product placement surface 14A of the shelf 14 from below, the LED illumination device 21 is rotated as shown in FIG. 2 to direct the LED element 22 upward. At this time, the switch 27 contacts the outer surface 26B of the cam 26 and closes the contact (FIG. 4), so that the LED element 22 is supplied with power. As a result, the LED element 22 emits light, and the light is irradiated upward (FIG. 2).

  FIG. 7 illustrates a state where a transparent plastic bottle beverage P is displayed on the product placement surface 14 </ b> A of the shelf 14. At this time, the plastic bottle drink P (product) is placed on the LED lighting device 21, and the light from the LED element 22 is irradiated into the plastic bottle drink P to create a fantastic image.

  Moreover, FIG. 8 has illustrated the state which displayed the can drink C on 14 A of goods mounting surfaces of the shelf 14. As shown in FIG. Here, since the can drink C (product) is not translucent (opaque), if it is placed on the LED lighting device 21, the light from the LED element 22 is blocked. Therefore, for example, a ridge 28 extending over the entire width is attached to the product placement surface 14 of the shelf 14 on the rear side of the LED lighting device 21 so as to be detachable. And if the space | interval of the protrusion 28 and the guard 18 is made smaller than one can drink C, the can drink C will not go ahead from it by the protrusion 28.

  Thereby, the inconvenience that the LED lighting device 21 is closed by the can beverage C (commodity) is solved, and the can beverage C is illuminated from the front lower side by the light from the LED element 22.

  On the other hand, when it is desired to illuminate the product below the shelf 14 from above, the LED illumination device 21 is rotated to direct the LED element 22 downward as shown in FIG. Also at this time, the switch 27 contacts the outer surface 26B of the cam 26 and closes the contact, so that the LED element 22 is supplied with power. As a result, the LED element 22 emits light and the light is emitted downward, and the product on the product placement surface 14A of the shelf 14 below the shelf 14 and the product on the deck pan 16 are illuminated from the front upper side. (Fig. 6).

  On the other hand, when illumination on the shelf 14 is unnecessary, that is, when illumination by the LED illumination device 21 is not performed, the LED illumination device 21 is rotated 90 degrees clockwise from the state of FIG. For example, 22 is directed in the cross-sectional direction of the rear shelf 14. At this time, since the outer surface 26A of the cam 26 is on the switch 27 side, the switch 27 is separated from the outer surface 26A and the contact is opened. Accordingly, since the power supply to the LED element 22 is cut off, the LED element 22 is turned off.

  In this way, the LED illumination device 21 having the LED elements 22 is rotatably attached to the shelf 14 and rotated to irradiate light from the LED elements 22 upward from the product placement surface 14A of the shelf 14. By enabling the selection of the state of irradiating light below the shelf 14, the LED illumination device 21 that irradiates light upward is placed on the product placement surface 14 </ b> A of the shelf 14. The displayed merchandise can be illuminated from below, and the merchandise displayed below the shelf 14 can be illuminated from above in the rotating state of the LED illumination device 21 that emits light downward.

  Thereby, various lighting effects can be given to the product from the LED lighting device 21 attached to the shelf 14, and the product sales effect can be significantly improved. In particular, the LED lighting device 21 is rotatably attached to the shelf 14, and the irradiation angle can be changed from the upper side to the lower side only by rotating, so that the operability is remarkably improved.

  In addition, since the LED illumination device 21 is turned off in a rotation state other than the state in which light is irradiated upward from the product placement surface 14A of the shelf 14 and the state in which light is irradiated downward, the shelf 14 5, the LED element 22 can be stored between the product placement surface 14 </ b> A and the lower surface of the shelf 14 and turned off as shown in FIG. 5. Depending on the product, the LED illumination device 21 can be turned off. The inconvenience of damaging the LED element 22 is also avoided. This is particularly effective when the shelf 14 is not a translucent plate.

  Further, in the showcase 1 in which the shelves 14 are provided in a plurality of stages as in the embodiment, when it is desired to make any particular shelf 14 stand out, only the LED lighting device 21 of the shelf 14 is turned on, and the other LEDs The lighting device 21 can be turned off.

  In particular, in the embodiment, the LED illumination device 21 is provided with a cam 26 in which the distance from the rotation shaft 23 of the LED illumination device 21 to the outer surfaces 26A and 26B changes according to the rotation angle, and the cam illumination device 26 can be brought into contact with the outer surface of the cam 26. Since the switch 27 is provided and the power supply to the LED lighting device 21 is controlled by opening and closing the switch 27, automatic turning on / off by rotation of the LED lighting device 21 can be realized with a very simple configuration. It is possible.

  In the above description, the LED element 22 is directed upward (FIG. 2) and downward (FIG. 6). However, while the switch 27 is in contact with the outer surface 26B of the cam 26, the LED Since the element 22 is lit, it is possible to change the light irradiation angle within a range of 45 degrees before and after the angle about the upward and downward directions.

  Here, in the above-described embodiment, the shelf 14 is made of a non-translucent plate material, and the on / off state is automatically controlled by the switch 27. However, the present invention is not limited thereto, and the switch 27 and the cam 26 are not provided. , Turning on / off by rotation may be abolished. According to the structure which concerns, the light from the LED element 22 can be irradiated at all the rotation angles of the LED illumination device 21.

  In addition to that, the shelves 14, guards 18, and price rails 17 may all be made of translucent plates and materials. Examples of such cases are shown in FIGS. In this case, the shelf 14, the price rail 17, the guard 18, and the price card 31 attached to the price rail 17 are all made of a translucent material (plate material). The LED element 22 is always energized and lit regardless of the rotation angle of the LED lighting device 21.

  In such a configuration, for example, as shown in FIG. 9, when the LED illumination device 21 is rotated and the LED element 22 is directed backward, the light from the LED element 22 is emitted toward the cross section of the shelf 14. . Since the irradiated light travels through the inside of the shelf 14, the shelf 14 becomes a light guide plate. And since light comes out from the whole product mounting surface 14A and the lower surface, it is possible to illuminate the products on the upper surface from the bottom including the upper and lower surfaces of the shelf 14 and the products on the lower side from the top. It becomes like this. Thereby, the illumination effect of goods can be improved further.

  Next, for example, as shown in FIG. 10, when the LED illumination device 21 is rotated to direct the LED element 22 forward, the light from the LED element 22 passes through the guard 18 through the cross section of the shelf 14, and the price. The price card 31 is irradiated from behind via the rail 17.

  As a result, the product advertisement effect by the price card 31 can be further improved, and the guard 18 itself can be illuminated by the light from the LED element 22, thereby further improving the product illumination effect. .

  In the embodiment, the open showcase is described as an example. is there.
