This shield 46 is made of the water white material with conductivity of an aperture, in the present embodiment, for the front openings 12 at showroom 11 makes light diffusion from LED illumination 40, not only will form smoothly, and will form as shown in Figure 4 cross section waveform or zigzag fashion with the throw light on outside 46A of shield 46 of 40 opposition sides of LED with the throw light on face of 40 side subtends of LED.

Thus, enter the back and incide the light of shield 46, in forming the outside 46A of cross section waveform or zigzag fashion,, can carry out diffusion at wide region thus along multi-direction refraction from LED 40 straight parallel of throwing light on.

According to relevant structure, when LED illumination 40 is lighted,, can throw light on to showroom 11 integral body effectively from the last the place ahead in the outside that is positioned at showroom 11 by the irradiates light of the illumination of the LED after shield 46 diffusions 40.

At this,,, compare situation of carrying out the illumination in the showroom 11 by existing fluorescent lamp and the situation of as present embodiment, carrying out the illumination in the showroom 11 by LED illumination 40 with reference to the experimental result of Fig. 6.In the relevant experiment, the device beyond the illumination is in order relatively to use identical showcase.In the experiment of using existing fluorescent lamp, as shown in figure 10, represented below the front portion of ceiling portion, storehouse inside ceiling panel portion, 4 grades of each shelves 106 that set up, to use T10 (f32mm) and T5 pipe 2 such classes of (f16mm) as illuminating device.In addition, in the experiment of as present embodiment, using LED illumination 40, as shown in Figure 7, represented 1 row LED illumination 40 to be installed in ceiling portion 33.

And, being provided with 4 grades of shelves at the showroom of each showcase 1 internal frame, the front end mounting has commodity S on each shelf, and the illumination of the light in the front that shines each commodity is measured.In addition, the front of the commodity S on the shelf of going up most is made as the A point, the front of the commodity S on the 2nd grade the shelf is made as the B point, the front of the commodity S on the shelf of 3rd level is made as the C point, the front of the commodity S on the 4th grade the shelf is made as the D point.

Thus, the illumination of the each point when using the T10 fluorescent lamp is A point 1260LX, B point 830LX, C point 600LX, D point 600LX.In addition, the illumination of the each point when using T5 pipe fluorescent lamp is A point 1800LX, B point 1300LX, C point 700LX, D point 470LX.In D point position in addition, T5 pipe fluorescent lamp is compared its illumination height with the situation of using the T10 fluorescent lamp as can be known.

With respect to this, as present embodiment, be installed under the situation of reflecting plate 45 of ceiling 33 inboards in LED illumination 40, the illumination of each point is A point 2380LX, B point 1520LX, C point 1000LX, D point 812LX.Thereby, know the illumination that shines the light of mounting on the commodity of each shelf, compare with using the situation that has such fluorescent lamp now, use the situation of LED illumination 40 all high on any point.

In addition,, then under the situation of using the T10 fluorescent lamp, be 468W, under the situation of using T5 pipe fluorescent lamp, be 356W, under the situation of using LED illumination 40, be 198W if compare with the required full consumed power of the illumination of above-mentioned each situation.Power with the situation of using the T10 fluorescent lamp is 100 o'clock, and the consumed power of T5 pipe fluorescent lamp is 76%, and the consumed power of LED illumination 40 is 42%.

Thereby, under the situation of as present embodiment, using LED illumination 40 as the illumination showroom 11 in, with as existing lighting devices such as a plurality of fluorescent lamps are set in the showroom situation compare the illuminating effect more than can playing on an equal basis.For this reason, self luminous illuminating device is not set, for example fluorescent lamp or other illuminating devices is not set below shelf 32 etc. even adopt at this shelf 32, the commodity of display especially pour into the mounting under upright state such as beverage of milk box and beverage bottle on each shelf 32, thus can be effectively to throwing light on the front of the commodity of front openings 12 subtends of showroom 11.

Thus, owing to do not need illuminating device, therefore not only can prevent the electric leakage that dewfall causes, and also not need to be used to install the illumination accessory of the socket of these illuminating devices and stabilizer etc., thereby can simplify the structure of shelf at each shelf 32.In addition, owing to can cut down the part number of packages, so can realize productive raising.

And, because the LED of the reflecting plate 45 by being installed in ceiling 33 illumination 40 can be played and existing such identical illuminating effect of situation that lighting devices such as a plurality of fluorescent lamps are set in the showroom, so the consumed power of showcase 1 integral body significantly can be reduced.

Further, this LED illumination 40 is because to harmful ultraviolet ray and the hot line of the showroom 11 interior commodity non-radiatings that display, so commodity can not heated and shine.Especially, because the LED illumination 40 of himself heating is set at the inboard of the ceiling 33 more outstanding than more close the place ahead of top front end of thermal wall 2, so just be that the outside of cold air gas curtain is shone in the showroom 11 from the outside of showroom 11.For this reason, the thermic loads in the showroom 11 that can illumination is relevant be changed to zero, thereby can prevent the reduction of the cold air efficiency of showcase 1 self in advance.Thereby, can realize that showcase 1 all operating cost reduces.

In addition, can avoid commodity being brought the unfavorable condition of bad influence by harmful ultraviolet ray of illumination.Thus, can keep commodity fresher and display.

In addition, because the substrate 42 of LED illumination 40 is installed, with the state of reflecting plate 45 butts that constitute by metallic plate under, install in the mode that can carry out heat exchange, so, be passed to reflecting plate 45 by LED illumination 40 from the heat extraction that substrate 42 produces, thus the radiating effect that acquisition is finished by reflecting plate 45.Thus, 40 heat that produced by substrate 42 of LED can being thrown light on are successfully emitted.

And LED illumination 40 is different with existing employed fluorescent lamp, owing to do not produce flicker, so can carry out stable illumination, can realize the illumination of suitable commodity.And then, LED illumination 40, because light modulation can be easy to change, thus can change light modulation according to the commodity of display in the showroom 11, thus make more effective illumination become possibility.

Further, LDE illumination 40 is owing to compare its durable years phenomenal growth with fluorescent lamp, so can not need the exchanging operation that throws light on.Miscellaneous operations such as processing of the discarded object of for this reason, can not need discharge by the standing and clearing house of change parts.

In addition, in the present embodiment, the light that advances from the straight parallel of LED illumination 40, the shield 46 of the conductivity of an aperture by being used to cover this LED illumination 40, can be to multi-direction diffusion, thus can be in the showroom 11 front openings 12 make light from LED illumination 40 in the wide region internal radiation, thereby also can be by LED illumination 40 effectively to all shining in the showroom 11 from direction irradiation.

Thus, the commodity that display with front openings 12 subtends of showroom 11, especially pour into the mounting under upright state such as beverage of milk box and beverage bottle, and can be to shining, thereby can improve the illuminating effect of commodity with the front of the commodity of front openings 12 subtends of showroom 11 via the luminous of the LED after shield 46 diffusions illumination 40.

In addition, in the present embodiment, shield 46 form be in the throw light on outside 46A of shield of 40 opposition sides of LED be cross section waveform or zigzag fashion, the outside that forms the shield 46A of this cross section waveform or zigzag fashion thus becomes prism, and make the multi-direction refraction of light of coming in from the straight parallel of LED illumination, and can reflect diffusion, thereby can be with luminous in wide region, the irradiation from the LED illumination by shield.

Thereby,, can play with lighting device such as existing such a plurality of fluorescent lamps and be arranged on the situation showroom in the illuminating effect more than equal like that from the light of this LED illumination 40 by above-mentioned.

In addition, in the present embodiment, because the shelf of putting canopy 32 that is erected in the showroom 11 is made of transparent material like that like above-mentioned, see through by what transparent material constituted from the LED illumination 40 of top irradiation luminous thus and put canopy, can't help to put canopy from LED illumination 40 luminous and hinder and make, can in showroom 11, advance on the whole, thereby can improve the illuminating effect of showroom 11 integral body.

Thereby, according to relevant structure, owing to illuminating device independently is not set and just can the commodity on each shelf be shone at each shelf 32, thus can not need to be used to install the attached part of illumination of the socket etc. of these illuminating devices yet, thus the structure that canopy is put in simplification.

In addition, except that shelf 32 grades are made of transparent material, also can be as shown in Figure 8, shelf 32 is made of the steel plate material that uses in the past, and below this shelf 32 installation LGP 48.This LGP 48 is made of for example acrylic resin etc., under the state that extends than more close the place ahead a little of front end of shelf 32 (comprise price horizontal bar 34 grades put canopy all) (LED throw light on 40 sides), is installed on shelf 32 following all.The front end of the LGP 48 that is provided with under the state more side-prominent more forward than shelf 32 is formed with light in part 49, this light in part 49 according to will from LED throw light on that light that 40 irradiations come receive and rearward reflection way constitute.

In addition, on the faces of side subtends below shelf 32 of LGP 48, be applied with a plurality of ditches of the light scattering that is used to make derivation or flaw etc., and this face is pasted with reflector plate 50.And, be that light-emitting area 52 is pasted with diffusion disk 51 at the face of opposition side below shelf 32 of LGP 48.

According to relevant structure, by from the top by in the LED illumination 40 irradiation showrooms 11, can be to light in part 49 than the side-prominent more forward set LGP 48 of each shelf 32, incident is luminous from LED illumination 40.Thus, export to the light at rear from light in part 49, the flaw or the reflector plate 50 that are formed by the face of side below shelf 32 carry out scattering, in the light-emitting area 52 of subtend by diffusion disk 51 diffusions, luminous.Thereby being situated between can send throw light on 40 the irradiates light from LED from the light-emitting area 52 of the whole LGP 48 that is provided with shelf 32 below by LGP 48.

For this reason, by carry out the diffused light irradiation from the light-emitting area 52 of LGP 48, can on the shelf 32 of below that is positioned at the shelf 32 that is provided with this LGP 48 and subtend, shine comprehensively.Thereby, only by the LED illumination 40 in illumination showroom, top 11, can shine in the showroom 11 from the top, not only can shine simultaneously the front of the commodity that are positioned in each shelf 32, and also can shine the commodity at the rear that is positioned in shelf 32, thus, can shine integral body in the showroom 11 effectively.

Especially, be provided with the illumination of the shelf 32 of LGP 48 up, luminous from LED illumination 40 by the light in part 49 that incides LGP 48, light-emitting area 52 luminous the carrying out of the LGP 48 that is provided with these shelf 32 subtends, thereby special illuminating device need be set, do not need socket or wiring etc., can simplify the structure of putting canopy thus.

In addition, in the present embodiment,,, be not to be defined in relevant structure so long as extend and the member that constitutes from the front side of shelf 32 along depth dimensions though LGP 48 is arranged on whole scope below the shelf 32.

For this reason, even under the situation that adopts relevant structure, identical in employing with above-mentioned situation in the installed inside LED of ceiling 33 illumination 40 like that, grade is not provided with under the situation of structure of fluorescent lamp or other illuminating devices below each shelf 32 that is provided with in showroom 11, can effectively shine the front of respectively putting the commodity that display on the canopy.Thereby, owing to do not need illuminating device at each shelf, thus the electric leakage that dewfall causes not only can be prevented, and can not need to be used for the attached part of illumination of socket that these illuminating devices install and stabilizer etc. yet, thus can simplify the structure of putting canopy.

In addition, by in reflecting plate 26 mounted LEDs illumination 40, can play and such identical illuminating effect of situation that the lighting device of a plurality of fluorescent lamps etc. was set in showroom 11 in the past, thereby can significantly reduce the consumed power of showcase integral body.

In addition, even in this case, this LED illumination 40 so the thermic load in the showroom 11 that can illumination is relevant is changed to zero, can prevent the reduction of the cooling effectiveness of showcase self owing to be arranged on the outside of cold air gas curtain in advance.Thus, can realize the reduction of the operating cost of showcase integral body.

In addition, in the reflecting plate of installing near the handrail hurdle main body 24 that the cold air sucting inlet of outer suction inlet 19 grades, is provided with 26, by emitting the heat by substrate 42 generations of LED illumination 40, thus can be to heating near the cold air sucting inlet that is easy to produce dewfall, thus generation can be suppressed to the dewfall of the reflecting plate 26, handrail hurdle main body 24 and the front top panel 25 that constitute handrail hurdle 20.

Thus, can utilize by LED illumination 40 heat of emitting and prevent dewfall, thereby can not need independently be provided for the heater that dewfall prevents usefulness on handrail hurdle 20.

In addition, in the above-described embodiments, handrail hurdle 20 is made of handrail hurdle main body 24, reflecting plate 26 and front top panel 25, but be not limited to relevant structure, even adopt handrail hurdle 20 is constituted with a part, and this handrail hurdle 20 formed by metal parts, and in the position of the front openings 12 that faces showroom 11 from inferoanterior reflecting part is set and at this reflecting part the structure of LED illumination 40 is installed, also can play same effect.

In addition, in the above-described embodiments, though LED illumination 40 is installed in the inboard and the handrail hurdle 20 of ceiling 33, and to shining from last the place ahead or inferoanterior in the showroom 11, but be not to be defined in this, so long as LED illumination 40 self is provided in the structure in the outside of showroom 11, also can be for example LED illumination 40 be installed and from irradiation showroom 11, side in side plate 5 grades.Thus, the thermic loads in the showroom 11 that can illumination is relevant be changed to zero, can prevent the low temperature display situation of the cold air efficiency of showcase 1 self in advance.

In addition, in addition, also can the LED illumination 40 same with the foregoing description be installed, in top or irradiation showroom 11, side at the end face dividing plate 8 of the showroom of internal layer ejiction opening 16 11 sides or side plate 5 etc.Also can throw light on effectively thus in the showroom 11.

Under above-mentioned each situation, by install with the place that as handrail hurdle 20, is easy to produce dewfall or with the place that is easy to produce dewfall carry out heat exchange, throw light on 40 substrate 42 of LED, can utilize from LED illumination 40 heat of emitting and prevent dewfall, thereby not need to be provided in addition the heater that dewfall prevents.

In addition, in the present embodiment, be that example exemplifies LED illumination 40 to be installed, but be not to be defined in this, even also can play same effect at the open showcase of flat pattern at so-called longitudinal type open showcase.
