Problems solved by technology

[0010] Therefore, since it is necessary to arrange the substrate at a predetermined angle to the rear of the pillar so that each LED element illuminates the front of the shelf on one side (or the other side) in the horizontal direction from the rear of the pillar, there is a lighting device arranged behind the pillar. The problem that the size of the main body becomes larger
[0011] In addition, in the related lighting device, it is configured to irradiate the reflected light from the reflector portion provided on the door side of the LED element into the showroom while directly irradiating the irradiated light from the LED element mainly toward the front of the shelf. It is difficult to control the irradiation direction (or irradiation range) of the light directly irradiated by the LED element, and cumbersome adjustment operations are required to achieve the most suitable illumination

Embodiment 1

[0070] First, refer to figure 1 and figure 2 The showcase 1 as Example 1 is demonstrated. figure 1 Represents the front view of the showcase 1 to which the present invention is applied, figure 2 A partially enlarged cross-sectional view of the showcase 1 is shown. The showcase 1 is composed mainly of a heat-insulating box (insulation wall) 2 opened in the front of a low-temperature showcase installed in a supermarket, a convenience store, or the like.

[0071] The heat-insulating box 2 is composed of an outer box 3 made of a steel plate opened at the front; and an inner box (not shown) made of a steel plate or a hard resin, which is inserted at intervals and opened at the front, in the outer box 3. ; and a heat insulating material formed by foaming and filling polyurethane foam (polyurethane) between the outer case 3 and the inner case.

[0072] Constitute showroom 5 in this inner box, and switch from the upper end of the front opening 6 of showroom 5 to the lower end wi...

Embodiment 2

[0120] Below, refer to Figure 11 and Figure 12 The lighting device 40 which is Example 2 provided in the said showcase 1 is demonstrated. Figure 11 It is a partial enlarged sectional view of the showcase 1 using the lighting device 40, Figure 12 is a perspective plan view of a portion of the lighting device 40 . This illuminating device 40 is constituted by a plurality of LED illuminating members 41 having substantially the same configuration as the LED illuminating members 16 of the illuminating device 15 of the first embodiment. It is also constituted by arranging a plurality of related LED lighting components 41 side by side up and down on the rear surface 8A of the pillar 8. The LED lighting components 41 are composed of the following: a substrate 18 on which a plurality of LED elements 17 are arranged; A plurality of reflective members 24 . . . , 25 . . . of light irradiated by the element 17; In this embodiment, since the structure other than the cover member 42 ...

Embodiment 3

[0130] Below, refer to Figure 13 The lighting device 45 as the third embodiment installed in the showcase 1 will be described. Figure 13 is a perspective plan view of a part of the lighting device 45 . The lighting device 45 in this embodiment is the same as the above-mentioned embodiment 1, and it is all formed by arranging a plurality of LED lighting components 46 side by side on the rear surface 8A of the pillar 8. The LED lighting components 46 are composed of the following: a plurality of The substrate 48 of the LED elements 17 ; the plurality of reflection members 24 . . . , 25 .

[0131] On a single substrate 48 constituting the LED lighting unit 46, as in the first embodiment, a plurality of LED elements 17 are arranged on a substantially straight line in the vertical direction or alternately shifted to one side and the other side in the horizontal direction, The first reflective member 24 and the second reflective member 25 are respectively arranged corresponding ...

Abstract

The invention provides a show box having illuminating apparatus for easily and efficiently illuminating front part of the shelf board. The show box (1) of the invention is provided with a door (7) mounted with the front opening (6) of the show room of the shelf board (9); a support (8) butted with the door; an illuminating apparatus (15) which is longitudinally arranged at the back part (8A) of the support; the illuminating apparatus comprises a base plate (18) longitudinally mounted with LED elements facing to back part of the show room for irradiating the lights; a first and second reflection parts (24, 25) facing to the front part of the shelf board in the show room located in one side or the other side of level direction of the support for reflecting the light from the LED elements, corresponding to each LED element, alternatively disposing these reflection parts in vertical direction.

Description

technical field [0001] The present invention relates to a display cabinet, which is equipped with: a display room with shelves for displaying goods, a see-through door for closing the front opening of the display room with a switch, and a door provided at the opening of the display room. A pillar abutting against the door at the front, and a lighting device vertically erected vertically behind the pillar are formed. Background technique [0002] In conventional showcases of this kind, a main body is constituted by a heat-insulating box with a front opening and a substantially U-shaped cross-section, and a showroom is formed inside with shelves for displaying goods in multiple stages. A plurality of pillars are provided on the front portion of the heat insulating box, and the pillars have predetermined intervals on the left and right sides and the two side portions. Between each of the pillars, a switch is provided to randomly close the door that can see through the interior...
