  Generally, in a low-temperature showcase in which the display room is cooled to a predetermined cooling temperature, when displaying beverages filled in cans or PET bottles, the shelf is inclined downward from the rear to the front. It is built in the display room. Therefore, goods, such as the said drink, will move to the near side by dead weight.

  Therefore, as described above, the products displayed on the front part of the shelf installed under the shelf are effectively illuminated by the illumination device such as a fluorescent lamp provided on the lower surface of the front part of the shelf.

  However, a fluorescent lamp used as an illumination device is used as illumination by converting electric energy into visible radiation, infrared radiation, and ultraviolet radiation and emitting visible light. At this time, heat loss occurs, so that there is a problem that not only the fluorescent lamp itself but also the display room is heated by the radiant heat from the fluorescent lamp. In addition, the fluorescent lamp has a problem of causing flickering due to the use of alternating current, and thus has a problem of adversely affecting the eyes. Furthermore, the fluorescent lamp is forced to be replaced due to a decrease in luminance or lighting failure due to aging. For this reason, there is a problem that the fluorescent lamp replacement work is forced and the work becomes complicated.

  Therefore, in recent years, an LED lighting device having an LED element has been adopted as a lighting device in order to eliminate the disadvantages caused by these fluorescent lamps. However, since the irradiation light from the LED element has strong directivity, in the LED lighting device provided on the front lower surface of the shelf, the irradiation light is mainly irradiated below the front of the shelf. Compared to the case of a lamp, there is a problem that the illumination to the back of the shelf provided on the lower side is remarkably insufficient.

  For example, if the product is contained in a tray formed of foamed polystyrene or the like, or if the shelf is installed in a substantially horizontal state, the product located on the back side will be Do not move to the side by its own weight. For this reason, the lighting device provided on the lower surface of the front part of the shelf located on the upper side mainly illuminates the front part of the shelf on which no product is placed, and thus effectively illuminates the rear product on which the product is actually displayed. It will not be possible.

  Therefore, in such a situation, the store clerk who manages the product needs to monitor the status of the product displayed in the display room, and when the product on the front side is gone, it is necessary to perform the advance work of sequentially replacing the product on the back side with the front side was there.

This LED illumination device is capable of changing the irradiation angle of light from the LED element in the depth direction of the display room, so that the irradiation angle of light from the LED element can be changed in the depth direction from the front of the shelf. It becomes possible to change arbitrarily over.

  Therefore, depending on the display status of the product displayed below the shelf in the display room, for example, when the product on the front side of the display room is taken out and the product is displayed only in the back, the directivity is high By changing the irradiation angle of the light from the LED element in the depth direction, it is possible to effectively illuminate the products without rearranging the products.

  In particular, since the irradiation angle of light from the LED element can be arbitrarily changed in the depth direction, a plurality of illumination patterns can be realized, and the display effect can be improved.

  According to the invention of claim 2, in the above invention, the LED lighting device has an LED mounting member for mounting the LED element on the lower surface of the shelf, and the LED mounting member is rotatably mounted on the shelf. Therefore, by rotating the LED attachment member attached to the lower surface of the shelf, the irradiation angle of the light from the LED element can be easily changed in the depth direction.

  According to the invention of claim 3, in the above invention, since the LED mounting member is rotatable by its own weight, even if the shelf on which the LED mounting member is provided is mounted so that the angle can be changed freely. It is possible to illuminate the portion immediately below the LED mounting member provided on the bottom surface of the shelf by rotating by its own weight and always having the center of gravity directly below.

  As a result, even if the shelf installation angle is changed, it is possible to effectively illuminate the display room located below the shelf without specially adjusting the mounting angle of the LED lighting device. It becomes.

  According to the invention of claim 4, in each of the above inventions, the LED lighting device has an LED mounting member for mounting the LED element on the lower surface of the shelf, and the LED mounting member is movable in the depth direction of the display chamber. Therefore, the mounting position in the depth direction of the LED mounting member on which the LED element is provided can be arbitrarily and easily changed.

  A cooler 39 of the cooling device is vertically installed in the inner layer duct behind the back partition plate 4A. When the blower corresponding to the inner layer duct is operated, the cold air exchanged with the cooler rises in the inner layer duct. Then, it is discharged from the inner layer discharge port 16 toward the inner layer suction port 18. And the cold air sucked from the inner layer suction port 18 is accelerated again by the blower.

  On the other hand, when the blower corresponding to the outer layer duct is operated, the air in the outer layer duct is raised in the outer layer duct and discharged from the outer layer discharge port 17 toward the outer layer suction port 19. Then, the air sucked from the outer layer suction port 19 is accelerated again by the blower. Thereby, a front and rear double air curtain is formed in the opening 12, and a part of the inner cool air curtain is circulated in the display chamber 11 to cool the display chamber 11.

  Next, the configuration of the front portion of the top wall 2B of the heat insulating wall 2 will be described with reference to a partially enlarged sectional view of FIG.

  With this configuration, when the LED lighting device 38 is turned on, the entire interior of the display chamber 11 is effectively spread from the upper front located outside the display chamber 11 by the irradiation light of the LED elements 40 after being diffused in the shade 46. It can be illuminated.

  Next, the LED lighting device 20 provided on the shelf 30 will be described with reference to FIGS. 4 and 5. FIG. 4 is a partial schematic cross-sectional view of the showcase 1 showing an illumination range by the LED lighting device 20 attached to the shelf 30 (substantially horizontally installed), and FIG. 5 is a partially enlarged view of FIG.

  First, the case where each shelf 30 is installed in the display room 11 substantially horizontally is demonstrated. The LED illumination device 20 is provided in the front part of the lower surface of the shelf 32 constituting each shelf 30 over the longitudinal direction of the shelf 32 (the left-right direction in the present embodiment). In the present embodiment, since the shelf board 32 is configured in a rectangular shape that opens to the lower surface, the LED lighting device 20 is attached to the lower surface of the product placement surface of the shelf board 32, thereby The LED lighting device 20 is housed in the shelf board 32. Therefore, the LED lighting device 20 does not appear in FIG.

  In FIG. 5, the lower shelf 30 shows a cross-sectional view of the LED lighting device 20, and the upper shelf 30 shows that the irradiation angle of the light from the LED element 21 by the LED lighting device 20 can be changed. Yes. The LED lighting device 20 illuminates the shelf 30 and the bottom plate 9 below the attached shelf 30. The LED lighting device 20 includes an LED attachment member 22 having a shelf attachment portion 23, an LED element attachment portion 24, and a reflection portion 25, and a substrate 26 on which a plurality of LED elements 21 are provided at predetermined intervals. Consists of Since the LED element 21 has the same configuration as the LED element 40, the description thereof is omitted.

  The shelf mounting portion 23 constituting the LED mounting member 22 is fixed to the lower surface of the shelf 30 (shelf plate 32 in this embodiment) by screwing or the like. The LED element attachment portion 24 and the reflection portion 25 are plate-like members configured to extend in the longitudinal direction (left-right direction) of the shelf 30, respectively, and the rear end of the LED element attachment portion 24 and the reflection portion 25. The front end is fixed at a predetermined angle (for example, approximately 90 °). In addition, the LED element attachment part 24 and the reflection part 25 may be integrally configured by bending a single plate-like member. Then, these center angle portions are pivotally attached to the front edge portion of the shelf attachment portion 23 with a predetermined resistance by the pivotal support member 22A.

  And the board | substrate 26 provided with the LED element 21 as mentioned above over the longitudinal direction (left-right direction) is provided in the rear surface (surface by the side of the reflection part 25) of the LED element attachment part 24 located in this side. A reflection plate 25A that reflects light is provided on the front surface (surface on the LED element mounting portion 24 side) of the reflection portion 25 located on the back side. Further, a translucent shade 27 is attached between the lower end of the LED element attaching portion 24 and the lower end of the reflecting portion 25.

  With such a configuration, the irradiation light from the LED element 21 with high directivity is irradiated toward the lower side of the shelf 30 via the shade 27. 4 and 5 is adjusted to an angle at which the surface of the shade 27 and the lower end (lower surface opening) of the shelf plate 32 are substantially flush with each other. In this state, the light emitted from the LED element 21 and the reflected light reflected by the reflecting plate 25A provided oppositely are displayed on the product displayed on the lower shelf 30, in particular, on the front side of the shelf 30. Illuminate the product.

  By rotating the LED element mounting portion 24 and the reflecting portion 25 in the depth direction of the display chamber 11 against the resistance around the axis of the pivot member 22A, the irradiation angle of the light from the LED element 21 is in the depth direction. Can be changed. That is, as shown in the LED lighting device 20 provided on the upper shelf 30 in FIG. 5, the LED element mounting portion 24 (and the reflecting portion 25 provided with a fixed angle) is connected to the axis of the pivot member 22A. By rotating the LED element 21 forward as the center, the LED element 21 can be made more downward, and the irradiation range (irradiation angle) can be the front part of the shelf 30 positioned on the lower side or the front thereof.

  The LED element 21 can be directed to the back partition plate 4A side by turning the LED element mounting portion 24 to the rear side against the resistance around the axis of the pivot member 22A, and its irradiation range (Irradiation angle) can be set to the rear part of the shelf 30 located on the lower side or the back partition plate 4A direction. In the present embodiment, since the pivot member 22A has a predetermined resistance in its rotation mechanism, the angle can be maintained even after the hand is released after the angle adjustment.

  Therefore, according to the display state of the goods displayed under the shelf 30 to which the LED lighting device 20 in the display room 11 is attached, for example, the goods on the front side of the display room 11 are taken out and the goods are displayed only in the back. In the case where the light is emitted, it is possible to effectively illuminate the product without rearranging the products by changing (adjusting) the irradiation angle of the light from the LED element 21 having high directivity in the depth direction.

  Further, when the commodity is displayed again on the front side of the shelf 30, the light irradiation angle of the LED element 21 is changed (adjusted) in the forward direction by rotating the LED mounting member 22 to the front side. Thereby, it is possible to realize appropriate product illumination according to the display state of the product.

  At this time, in the state where the angle is adjusted so that the lower surface of the shade 27 provided on the LED mounting member 22 is substantially flush with the lower end (lower surface opening) of the shelf plate 32 as described above, And the reflected light reflected by the opposing reflector 25A are provided so as to illuminate the products displayed on the lower shelf 30, in particular, the products displayed on the front side of the shelf 30. Yes. Therefore, it becomes possible to adjust the irradiation light from the LED element 21 of the LED lighting device 20 to illuminate the product displayed on the front side of the lower shelf 30 by groping, thereby improving workability. it can.

  Thus, since the irradiation angle of the light from the LED element 21 can be arbitrarily changed in the depth direction, a plurality of illumination patterns can be realized, and the display effect can be improved.

  In particular, the rotation angle of the light from the LED element 21 can be easily changed by rotating the pivot member 22A around the pivot member 22A as a center, and the convenience can be improved.

  FIG. 6 shows a case where the LED illumination device 28 in the above embodiment is attached to a shelf board 32A having no opening on the lower surface. In this case, the LED mounting member 22 in the above embodiment does not have the shelf mounting portion 23, and the LED mounting member 29 constituted by the LED element mounting portion 24 and the reflecting portion 25 is provided on both sides of the shelf plate 32A. The center angle portion formed by the rear end of the LED element mounting portion 24 and the front end of the reflecting portion 25 is held at a predetermined resistance by holding members 47, 47 provided on the lower surface of the front portion of the shelf 32A. It is attached so that it can rotate freely.

  Also by this, by rotating the LED attachment member 29 in the near direction or the depth direction around the central angle portion constituted by the LED element attachment portion 24 and the reflection portion 25, as in the above embodiment, The irradiation angle of the light from the LED element 21 can be easily changed, and the convenience can be improved.

  On the other hand, in FIG. 7, each LED illumination device 20 provided in each shelf 30 as shown in FIG. 4 is adjusted from the state in which the irradiation angle of light from the LED elements 21 is adjusted to be on the front side of the lower shelf 30. A state is shown in which the shelf 30 is installed in the display chamber 11 at a predetermined angle. As shown in the figure, when each shelf 30 is installed at a low inclination from the rear to the front while maintaining the irradiation angle of light from the LED lighting device 20 as shown in FIG. 4, the front end of the upper shelf 30. Is moved to the back side from the front end of the lower shelf 30, the LED element 21 of the LED lighting device 20 provided in each shelf 30 illuminates the rear from the front portion of the lower shelf 30. .

  Therefore, when a product is displayed from the front side of the shelf 30, the LED illumination device 20 provided on the upper shelf 30 cannot illuminate the product displayed on the front part of the shelf 30, The effect is significantly reduced. Therefore, in this case, the user needs to adjust the irradiation angle of the LED lighting device 20 provided in each shelf 30.

  Note that FIG. 8 shows an illumination range by the fluorescent lamp 100 that has been conventionally provided on the shelf 30, and the fluorescent lamp 100 is irradiated with light from the entire outer periphery of the fluorescent tube. It is hard to happen.

It becomes possible.

  Thereby, even if the erection angle of the shelf 30 is arbitrarily changed, the inside of the display chamber 11 positioned below the shelf 30 can be adjusted without particularly adjusting the attachment angle of the LED illumination attachment portion 53. It becomes possible to illuminate effectively. In particular, as the inclination angle of the shelf 30 increases, the effect obtained by illuminating the front portion of the lower shelf 30 increases, and the configuration becomes more effective.

  FIG. 11 shows an LED lighting device 55 as another embodiment. The LED lighting device 55 is formed with a long hole 57 in which a holding member 56 provided on the lower surface of the front portion of the shelf 32 extends in the front-rear direction.

Therefore, the mounting position in the depth direction of the LED mounting member 54 provided with the LED element 21 can be arbitrarily and easily changed.

  Therefore, the mounting position of the LED element 21 can be adjusted according to the display state of the product in the display chamber 11 located below the shelf 30, and is configured to be rotatable in the depth direction from the front to the rear. Thus, it is possible to realize illumination of the product more effectively.

  FIG. 12 shows an enlarged cross-sectional view of an LED lighting device 60 as another embodiment. In such an embodiment, sliding members 61 and 61 extending in the depth direction are provided on both sides of the front surface of the shelf 30. Further, in this case, the LED lighting device 60 forms a predetermined angle (about 90 ° in this embodiment) between the LED element mounting portion 24 including the LED element 21 and the substrate 26 in the embodiment of FIG. 4 and the front end thereof. It has the LED attachment member 62 which consists of the reflection part 25 attached in this way. The LED element mounting portion 24 of the LED mounting member 62 is slidably mounted on the lower surface of the sliding member 57 in the depth direction.

  Thereby, the LED attachment member 62 attached to the front portion of the lower surface of the shelf 30 is arbitrarily movable in the depth direction of the display chamber 11 by the sliding member 61 provided on the shelf 30, so that the LED element 21 is provided. The mounting position in the depth direction of the LED lighting device 60 to be used can be arbitrarily and easily changed.
