Description

  The present invention relates to a showcase in which a display room in which a shelf for displaying products is constructed is defined by a transparent plate on the front surface of a main body, and more particularly, to a technique for illuminating a product displayed on the shelf.

  Conventionally, as a showcase, a shelf for displaying merchandise is installed in a display room configured in the main body, and the front opening of the display room is closed by a see-through door so that it can be opened and closed. There was a showcase with a lighting module made of LED elements (see Patent Document 1).

JP 2009-112351 A

As described above, if an LED element is used as the illumination module, the illumination module is slimmed, the visibility of the product is reduced due to the overlap between the display product and the illumination module, and the illumination module and the product when the product is taken in and out. Can be suppressed.
However, in the conventional showcase, the irradiation direction of the illumination light by the LED element is directed to the shelf side by the shade, and the products displayed on the shelf are directly illuminated with light.

  For this reason, when products such as PET bottles are displayed side by side on the front end of the shelf, products close to the illumination module can be illuminated brightly, but as they move away from the illumination module, they become darker, so the illuminance (luminance) variation of the products is large, In addition, even in products that are relatively close to the illumination module, the shaded portion that is not exposed to direct light from the illumination module becomes dark, so that even if the average illuminance is high, an overall dark impression is given to the customer.

  Therefore, an object of the present invention is to provide a showcase that can reduce the illuminance (brightness) variation of products arranged on a shelf and the shadow between products.

In order to achieve the above object, a showcase according to the present invention is a showcase in which a display room in which a shelf for displaying merchandise is constructed is defined by a transparent plate on the front surface of the main body, and has an LED light source, The illumination module includes an illumination module in which the luminous intensity near the light distribution center is increased by narrowing the light distribution angle of the LED light source, and the illumination module sandwiches a space between the transparent plate and a product row arranged at the front end of the shelf. And the light distribution center increases the intensity of direct light with respect to a product located at a far position among the products arranged on the front end of the shelf as compared with the direction toward the facing lighting module or the direction toward the facing lighting module. In this way, the product is set in a direction slightly inclined to the shelf side and irradiates light on the transparent plate and the products arranged on the front end of the shelf, and the product displayed on the shelf is directly exposed to the light and the transparent plate. It illuminated with reflected light.
In such a configuration, since the product displayed on the shelf is illuminated using the direct light from the illumination module and the reflected light from the transparent plate, the reflected light from the transparent plate is applied to the product part not directly irradiated with light. Can be irradiated.

Here, the light distribution center can be set between the person direction towards the opposite lighting module to a direction towards the product farthest of products arranged in front of the shelf side.
In such a configuration, light with a large luminous intensity near the center of the optical axis is irradiated toward a product on the far side, and light with a large luminous intensity near the center of the optical axis is directed toward the side far from the LED of the transparent plate. It can be irradiated and reflected, and the illuminance of the product at a position far from the LED can be increased.

Further, the front surface of the main body is closed openably and closably by a door provided with the transparent plate, and each of a left end portion and a right end portion of the front surface of the main body opened and closed by the door and / or an upper end portion and a lower end of the front surface of the main body. The lighting module can be arranged in each of the sections .
In such a configuration, in the showcase where the front surface of the main body is opened and closed freely by a door provided with a transparent plate, and the door is opened and closed to take out products, the lighting module is mounted on the shelf when the door is closed. The displayed product is illuminated with direct light and reflected light from a transparent plate.

Moreover, the said illumination module is formed in a rod shape , The said illumination module can be inserted in the recessed part or groove | channel provided in the left-right support | pillar frame which comprises the opening part of the said main body front surface along a longitudinal direction .
In such a configuration, the protrusion of the illumination module from the support frame can be reduced, and the visibility of the product can be reduced and the product can be prevented from coming into contact with the illumination module .

Further, the four strut frames constituting the main body are formed of a common molded part having two grooves for fitting two plates defining the two surfaces of the main body so that they cannot be opened and closed. the groove is not fitted the plate of left and right strut frames forming the opening, a front KiTeru bright modules can be interposed.
In such a configuration, by the four posts frame a common molded component can reduce the kinds of the molded parts constituting the showcase, and inserted the lighting module, the groove for fitting the plate by location, perform the arrangement of the lighting module to strut frame easily, and can reduce the projection of the illumination module from post frame.

Further, in a state of closing the door, left and right frames constituting the door, from the tip of the lighting module overhanging the center side of the opening, the lighting module, the right and left frames constituting the door It can be arranged on the back side.
In such a configuration, with the door closed, the illumination module is hidden behind the left and right frames constituting the door so that the illumination module cannot be directly seen from the front side of the main body.

In here, in the lighting module, preferably the light distribution angle of 1/2 of the range of the maximum luminous intensity of the LED light source is down to approximately 50 degrees.
In such a configuration, the light distribution angle (1/2 beam angle) in the range of 1/2 of the maximum luminous intensity is reduced to about 50 degrees, so that the amount of light irradiated to the product and the transparent plate located far from the illumination module And the ratio with the irradiation amount of the light to the goods near a lighting module and a transparent plate becomes appropriate.

According to the showcase and the lighting module according to the present invention, the product displayed on the shelf is illuminated with direct light and reflected light from the transparent plate that defines the front surface of the main body. Moreover, the shadow between goods can be reduced.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
FIG. 1 is a front view of a showcase 1 according to the present embodiment. The showcase 1 shown in FIG. 1 is a vertical or low-temperature showcase for freezing or refrigeration installed in, for example, a supermarket or a convenience store.
In this embodiment, the low-temperature showcase is used, but a heat-retaining showcase or a heat-retaining / refrigerating showcase may be used.

The showcase 1 includes a box body 3 in which a display chamber 2 is defined, and a pedestal angle 4 attached to the bottom surface of the box body 3.
The display room 2 opens to the front (exhibition side, customer side, sales floor side), and the front opening of the display room 2 is closed openably and closable by a door 6 having a glass plate 5 which is a transparent plate through which the inside can be seen. Is done. The door 6 is an open door whose one end is pivotally supported on the side of the box 3.

Both side surfaces and the back surface of the display chamber 2 are defined and closed by glass plates that are transparent plates that allow the inside to be seen through, and the display chamber 2 is surrounded on four sides by glass plates. However, it may be a showcase in which at least one of the both side surfaces and the back surface of the display chamber 2 is defined by a heat insulating panel that cannot be seen through.
In addition, the glass plate (including the glass plate of the door 6) defining the display chamber 2 is a double glass provided with a hollow layer, and a transparent heat insulating film is applied to the glass surface or a transparent heat insulating paint is applied. It is preferable to improve heat insulation by doing.

The display chamber 2 is provided with a plurality of shelves 8 for placing products 7 such as plastic bottles. A shelf column (not shown) is provided on the front and rear sides of both side surfaces constituting the inner wall of the display chamber 2, and the shelf 8 is detachably attached to a plurality of engagement holes formed in the shelf column. It will be erected.
Front and rear surfaces and side surfaces of the pedestal angle 4 are covered with a decorative panel, whereby a machine room 9 is formed below the display room 2.

The machine room 9 contains an evaporator, a cool air circulation blower, a compressor, a condenser, a condenser blower, and the like that constitute a cooling device, and the cold air circulation by the cool air circulation blower is performed on the bottom wall of the display chamber 2. This is performed through the formed cold air inlet and cold air outlet.
The machine room 9 accommodates mounting bases 11 having casters 10 attached to four corners, and components such as a compressor constituting a cooling device are disposed on the mounting base 11.

FIG. 2 is a cross-sectional view on the horizontal plane of the display chamber 2 with the door 6 closed, and shows the front side of the display chamber 2. In FIG. 2, illustration of a frame constituting the door 6 is omitted.
The box 3 that defines the display chamber 2 includes four support frames 12, a door 6 provided with glass plates 5, glass plates 13 that define both sides and the back of the display chamber 2, and a top plate 17 And a bottom plate (not shown).

As shown in FIG. 3, the column frame 12 has two grooves 14 and 14 (concave portions) and a shelf 8 installed in the display chamber 2 for fitting the two glass plates 13 defining the display chamber 2. This is a resin molded part that is integrally provided with a shelf support 15 for the purpose. By changing the direction of the support frame 12 and turning it upside down, it is possible to configure the four support frames constituting the box 3 using the support frame 12 which is a common molded part.
Here, a glass plate 13 is fitted between the left and right column frames 12 on the back side, between the left and right column frames 12 on the left side, and between the left and right column frames 12 on the right side. Since the opening is opened and closed by the door 6, the glass plate 13 is not fitted between the left and right column frames 12 on the front side.

In this embodiment, as shown in FIGS. 3 and 4, a bar-like lighting module 16 (light source) is provided in each of the grooves 14 into which the glass plates 13 of the left and right column frames 12 on the front side are not fitted, as shown in FIG. The lighting module 16 illuminates the product 7 such as a plastic bottle placed on the shelf 8.
As shown in FIG. 5, by changing the direction of the support frame 12 which is a common part and reversing the top and bottom, the four support pillars on the right front, left front, right rear and left rear are configured. The support frame 12 is formed with two grooves 14 and 14 (concave portions) for fitting two glass plates 13 defining the display chamber 2. A lip-shaped portion bent inward is formed on the edge that is the outside of the chamber 2, and a glass plate is formed in the narrowed portion between the tip of the lip-shaped portion and the opening edge that is the inside of the display chamber 2. 13 is sandwiched and held.
And the groove | channel 14 in which the glass plate 13 of the right front and left front support | pillar frame 12 is not inserted is used as a groove | channel which inserts the illumination module 16. FIG.

Here, although the width of the illumination module 16 is narrower than the width of the bottom of the groove 14, it is larger than the width of the constricted portion narrowed by the lip-shaped portion, so that the glass plates 13 of the right front and left front column frames 12 are not fitted. After the lip-shaped portion 14a of the groove 14 is cut, the lighting module 16 is inserted into the groove 14 whose opening end is widened by cutting the lip-shaped portion 14a as shown in FIG. is there.
As shown in FIG. 7, the illumination module 16 is configured such that an LED lamp (light source) including an LED (Light Emitting Diode) 16 a and a lens 16 b is lighted at a constant interval (for example, about 10 to 15 mm) in the longitudinal direction. It is arranged and integrated as it exists.

The LED 16a uses, for example, a power consumption of about 0.1 W to 0.5 W and a light distribution angle (1/2 beam angle) in the range of ½ of the maximum luminous intensity is about 120 degrees.
Further, the lens 16b is configured to restrict the 1/2 beam angle of the LED 16a in a plane orthogonal to the longitudinal direction of the support frame 12 (illumination module 16) to about 50 degrees. The intensity around the center of the optical axis is increased.

The aperture of the light distribution angle by the lens 16b irradiates light directly on the nearest product 7 among the products 7 arranged on the front end of the shelf 8, and also on the farthest product 7 arranged on the front end of the shelf 8. It is a value that should be set as appropriate so that sufficient direct light can be irradiated, and the 1/2 beam angle is not limited to 50 degrees.
It should be noted that when emitted from the lens 16b, light is emitted substantially symmetrically with respect to the center of the optical axis.

The lighting module 16 has a width W of about 15 mm and a height H of about 13.5 mm, and the length is adjusted to the height of the display chamber 2.
Then, when the illumination module 16 is inserted into the groove 14, the height of the illumination module 16 is set so that the projection height of the illumination module 16 from the opening edge of the groove 14 is, for example, 1 mm or less. 16 prevents the area of the opening of the display chamber 2 from being narrowed.

When the projection height of the lighting module 16 from the opening edge of the groove 14 is increased, the visibility of the product 7 may be reduced due to a part of the product 7 placed on the left and right ends of the shelf 8 being hidden behind the lighting module 16. Further, there is a possibility that the lighting module 16 and the product come into contact with each other when the product 7 is put in and out. On the other hand, if the illumination module 16 can be inserted into the groove 14 so as not to jump out of the opening edge of the groove 14, the visibility of the product 7 is reduced by the illumination module 16, and the product 7 is taken in and out. At this time, the lighting module 16 and the product can be prevented from contacting each other.
Further, the optical axis centers of the illumination modules 16 inserted in the grooves 14 are directed to the illumination modules 16 facing each other.

  That is, two grooves 14 into which the glass plates 13 of the left and right column frames 12 on the front side are not fitted, in other words, two grooves that are positioned at the left and right ends of the opening of the display chamber 2 and in which the illumination module 16 is inserted. 14 is a space between the glass plate 5 of the door 6, which is a transparent plate defining the front surface of the main body, and the product row lined up at the front end of the shelf 8, facing on a plane parallel to the opening surface of the display chamber 2, If the illumination module 16 is inserted so that the optical axis center coincides with the opening direction of the groove 14 with respect to the groove 14, the optical axis centers of the illumination module 16 are directed to the illumination modules 16 facing each other. become.

8A shows the showcase 1 with the door 6 open, and FIG. 8B shows the showcase 1 with the door 6 closed. As shown in FIG. 8, with the door 6 closed, the left and right frames 6a and 6a of the door 6 are located closer to the opening of the display chamber 2 than the tip of the illumination module 16 (the tip of the LED 16a including the lens 16b). The lighting module 16 (LED 16a) is arranged on the back side of the left and right frames 6a, 6a of the door 6 so as to project to the center side.
As a result, when the showcase 1 is viewed from the front, the illumination module 16 (LED 16a) is hidden behind the left and right frames 6a, 6a of the door 6 and is not directly visible from the front. 16 (LED 16a) directly enters and it is difficult to feel dazzling.

When the lighting module 16 (LED 16a) is turned on, as shown in FIG. 9, the light from the lighting module 16 (LED 16a) is directly irradiated to the products 7 arranged at the front end of the shelf 8 in a state where the door 6 is closed. At the same time, the glass plate 5 constituting the door 6 is also irradiated, and the light reflected by the glass plate 5 is irradiated to the products 7 arranged at the front end of the shelf 8.
That is, the products 7 arranged at the front end of the shelf 8 are illuminated by direct light from the illumination module 16 (LED 16a) and also illuminated by reflected light from the glass plate 5.

  When illuminating the product 7 arranged at the front end of the shelf 8 with only direct light from the illumination module 16 (LED 16a), the light does not reach the side surface of the product 7 that is shaded when viewed from the illumination module 16 (LED 16a), Although a clear shadow appears on the product 7, the reflected light from the glass plate 5 is applied to the product 7 at an angle different from that of the direct light from the illumination module 16 (LED 16a), and thus the illumination module 16 (LED 16a). Therefore, the side of the product 7 that is shaded as viewed from the side can be irradiated with light, and the shadow of the product 7 can be reduced.

  Further, since the light distribution angle of the LED 16a is reduced by the lens 16b, the light intensity near the light distribution center (near the optical axis center) increases, and the light distribution center is the far side of the products 7 arranged at the front end of the shelf 8. Therefore, the product 7 far from the lighting module 16 (LED 16a) can be directly irradiated with a lot of light, and further, the position far from the lighting module 16 among the light irradiated to the glass plate 5 constituting the door 6 Since the incident angle with respect to the glass plate 5 increases and shows a high reflectance, the illuminance of the product 7 far from the illumination module 16 (LED 16a) can be increased.

Furthermore, since the illumination by the direct light and the illumination by the reflected light are performed by the pair of illumination modules 16 (LEDs 16a) arranged at the left and right ends with the product row in between, the product 7 at a position far from one illumination module 16 is provided. Can be supplemented with light (direct light and reflected light) from the other lighting module 16, and the products 7 arranged on the front end of the shelf 8 can be illuminated on an average basis. Illuminance (luminance) variation can be suppressed.
As described above, in the showcase 1 of the above embodiment, the illuminance (brightness) variation for each product 7 arranged on the front end of the shelf 8 and the shadow on each product 7 can be suppressed, and the product 7 arranged on the front end of the shelf 8 is entirely Looks bright.

If the illuminance (brightness) of each product 7 arranged at the front end of the shelf 8 varies, or if each product 7 is shaded, the overall impression will be given to the customer even if the average illuminance is high. However, if the illuminance (brightness) variation for each product 7 and the shadows on the individual products 7 can be suppressed, even if the average illuminance is the same, the overall impression can be given to the customer and the purchase will be motivated. it can.
When the door 6 is opened, the products 7 arranged at the front end of the shelf 8 are not illuminated with the reflected light from the glass plate 5 constituting the door 6, but are exclusively illuminated with direct light from the illumination module 16 (LED 16a). As a result, the illuminance (brightness) variation for each product 7 and the shadow of each product 7 become larger than when the door 6 is closed.
However, since the darkness due to the shadow when the door 6 is opened is conspicuous, the illumination effect by the reflected light and direct light when the door 6 is closed is more conspicuous, and the customer's willingness to purchase is the state where the door 6 is closed Since the customer opens the door 6 after the product to be purchased is determined, it is only necessary to give a bright impression as a whole with the door 6 closed.

FIG. 10 shows the required light distribution characteristics for aligning the illuminance for each product 7 arranged on the front end of the shelf 8 by illuminating the products 7 arranged on the shelf 8 with only direct light from the illumination module 16.
That is, theoretically, the product 7 located at the center of the front end of the shelf 8 receives substantially the same light from the left and right illumination modules 16, and the sum of the lights determines the illuminance. As for the product 7 arranged at the shifted position, the light amount decreases from one of the left and right illumination modules 16 and conversely increases the light amount from the other, so that the same illuminance as the product 7 located in the center is obtained by such cancellation. You can do it.

However, it is difficult to realize such an ideal light distribution, and in the case of illumination only by direct light, if the product 7 is a box-like shape having no irregularities, it can be uniformly brightened. If the product 7 to be displayed is uneven, such as a plastic bottle, for example, as shown in FIG. 11, the projection on the side close to the illumination module 16 blocks light and causes the product 7 to be shaded. .
FIG. 12 is a diagram showing the characteristics of reflected light when light from the illumination module 16 is reflected on the glass plate 5 of the door 6 and the product 7 is illuminated with reflected light together with direct light. Only the reflection characteristics of light from the illumination module 16 arranged on the left side of the front surface of the main body are shown.

The light reflectance on the glass plate 5 increases as the incident angle of the light with respect to the glass plate 5 increases, and the incident angle increases as the light enters the glass plate 5 at a position farther from the illumination module 16. Since the light is reflected at the same reflection angle, the light reflected at a far position exceeding the central position in the left-right direction of the glass plate 5 is not irradiated on the product 7 and does not contribute to the increase in illuminance.
However, in the reflection region of the glass plate 5 where the reflected light is irradiated to the product 7, the farther from the illumination module 16, the higher the reflectance, so that the product 7 far from the illumination module 16 can be effectively illuminated, Moreover, as shown in FIG. 13, the light from the other illumination module 16 is irradiated with the reflected light reflected by the glass plate 5 on the shaded portion of the product 7 where the direct light from one illumination module 16 does not reach. And shadows generated between the products 7 can be reduced.

By the way, in the said embodiment, although the optical axis center of the illumination module 16 inserted in the groove | channel 14 was turned to the mutually facing illumination module 16, it is on the shelf 8 side from the direction which faces the opposing illumination module 16. It can be set in a slightly tilted direction, for example, in a direction toward the farthest product 7 among the products 7 arranged on the front end of the shelf 8.
As described above, of the light emitted from the illumination module 16, the reflected light of the light incident on the glass plate 5 far from the illumination module 16 is wasted without being applied to the product 7 placed on the shelf 8. The optical axis center of the illumination module 16 is tilted toward the product 7 (shelf 8) side from the other illumination module 16 that is opposite, and the intensity of light irradiated on the region on the glass plate 5 where the reflected light is not applied to the product 7 is reduced. The brightness of the direct light with respect to the product 7 at a relatively far position is relatively increased so that the illumination can be effectively performed.

  However, in order to incline the optical axis center of the illumination module 16 with respect to the opening direction of the groove 14, it is necessary to form the pair of left and right illumination modules 16 as separate parts, or from the opening edge of the groove 14. However, if the center of the optical axis of the illumination module 16 is directed toward the illumination modules 16 facing each other, the pair of left and right illumination modules 16 is a common component. Further, the projection of the illumination module 16 from the opening edge of the groove 14 can be minimized.

  Moreover, a pair of lighting modules 16 arranged to face each other can be arranged on the back side of the frame of the door 6 that is a frame constituting the front surface of the main body. In this case, when the door 6 is opened, the direct light from the lighting module 16 does not reach the product 7 sufficiently, and the illuminance of the product 7 arranged on the front end of the shelf 8 is lowered. As described above, the door 6 is opened. When the door 6 is closed, the darkness due to the shadow is conspicuous, and the lighting effect by the reflected light and direct light when the door 6 is closed is further conspicuous, and the customer's willingness to purchase is determined with the door 6 closed. When the door 6 is closed, it is possible to illuminate in the same manner as when the illumination module 16 is inserted in the groove 14 of the support frame 12, so that the purchase motivation can be sufficiently evoked, and the illumination module 16 and the product 7 overlap. It is possible to prevent the visibility of the product 7 from coming into contact with the illumination module 16 when the product 7 is taken out.

In addition, a pair of lighting modules 16 opposed to each other can be arranged at the upper and lower ends instead of being arranged at the left and right ends, and a pair of lighting modules 16 are arranged at the left and right ends, and also at the upper and lower ends. A pair of lighting modules 16 can be arranged, and the lighting modules 16 can be arranged only on one side of the left and right ends or only on one side of the upper and lower ends. Moreover, LED which illuminates goods with direct light and the reflected light from the glass plate 5 (transparent plate) can also be arranged in the center part of the front surface of the main body.
In addition, the showcase 1 of the present embodiment is provided with a door 6 for opening and closing the display chamber 2 on the front side of the main body. It is obvious that the illumination module 16 similar to the above embodiment can be applied to the case.

  Furthermore, in the present embodiment, the front side which is the customer side is a showcase that is opened and closed by the door 6, but the front side is closed by a glass plate (transparent plate), and the showcase provided with the opening and closing door on the rear side, Illumination technology of the present application, that is, a glass in which a plurality of LEDs are interspersed along the longitudinal direction of the frame in each of the opposing portions in the display chamber of the frame constituting the front surface of the main body, and the direct light by the LEDs and the glass that blocks the front surface The structure which illuminates the commodity displayed on the shelf with the reflected light from the board can be applied, and the same effect as the above embodiment can be obtained.

Moreover, in the said embodiment, although all the 4 surfaces which define the circumference | surroundings of the display chamber 2 were comprised with the glass plate (transparent plate), the decorative panel was affixed on at least 1 surface other than the front surface, for example on a heat insulating material. It can be composed of an opaque plate.
Moreover, in the said embodiment, although the glass plate was used as a transparent plate, a transparent resin plate can be used as a transparent plate, for example, A transparent plate is not limited to a glass plate.
