(Operation of lighting device 3)
When a voltage is applied to each LED 40, 41 from a power source, illumination light (for example, white light) is emitted from each LED.

  From the LED 40 mounted on the first surface 30a of the substrate 30, LED light is mainly emitted upward. The emitted LED light enters the display article B from below and passes through the semi-cylindrical or cylindrical display article B (a light-transmitting member on which information indicating a product for sale is printed and displayed). And a part of the LED light is transmitted through the translucent first cover 23 or the second cover 24 and attached to the stage 25, and The light passes through the article selection push button 8 attached to the front panel 7 and is emitted to the article viewer side.

  The LED light emitted from the LEDs 41 mounted on the second surface 30b of the substrate 30 is mainly emitted downward. The emitted LED light irradiates the back panel 22, and the light reflected there is transmitted through the front panel 7 (electric lighting plate) and emitted to the article viewer side, and part of the LED light is transmitted through. Visible through the optical first cover 23 or the second cover 24, and through the display unit 26 attached to the stage 25 and the pushbutton 8 for article selection attached to the front panel 7. It is emitted to the person side.

  In the operation of the lighting device 3 described above, the color, intensity, etc. of the illumination light can be made different corresponding to each of the exhibition article groups b1, b2, b3, and the color of the illumination light with time. The control unit 6 can also control the intensity and the like to change. In addition, each display article B can be controlled independently.

(Effect of embodiment)
According to the embodiment described above, the following effects can be obtained.
(1) In the illuminating device according to the present embodiment, the covers formed with different lengths are mounted in a different arrangement order across the substrate 30, and the boundary between the cover and the other cover does not match. Since a portion weak against bending can be eliminated, the cross-sectional shape can be reduced and the rigidity can be increased even with a long lighting device.

  (2) Since it is not necessary to connect a short illuminating device in the illuminating device which concerns on this Embodiment, the connector for a connection, a harness, etc. become unnecessary, and it has the effect of a cost reduction while improving assembly property.

  (3) The long substrate 30 is formed with a plate thickness of about 1 mm to 1.6 mm, which is generally used in the past, with a plate thickness of 2.4 mm, so that the rigidity of the substrate itself is made larger than before. Since the structure is used, a reinforcing member is not necessary, and the cost can be reduced.

  (4) The covers that are mounted on the first surface 30a and the second surface 30b of the substrate 30 are a plurality of types of covers that are formed with different lengths. However, since the same cover can be used on the first surface 30a and the second surface 30b, there is an effect of reducing mold costs, member costs, material costs, and the like.

  (5) According to the illumination device according to the present embodiment, since a chip-type LED having a wide viewing angle is used, an illumination device suitable for thinning can be realized.

  (6) In the lighting device according to the present embodiment, the individual reflector case 27 corresponding to each LED 40 is mounted, and the influence of linear expansion due to the heat of the reflector case 27 and the substrate 30 can be almost ignored. The reflective case 27 can be attached to the vicinity of the lens so that the reflection efficiency can be improved.

  (7) According to the lighting device according to the present embodiment, when this lighting device is applied to a vending machine having different numbers of display articles B, arrangement intervals, etc., the cover, the reflective case, etc. Since it is not necessary to newly design and manufacture a cover, a reflective case, etc., it is possible to make a great contribution to shortening the design development period and reducing manufacturing costs.

  (8) According to the lighting device according to the present embodiment, an integrally configured lighting device corresponding to the number of exhibition items for one stage of the display article B can be provided, so that it can be assembled into a vending machine. In addition to being excellent, it has the effect of being excellent in maintainability.

  (9) In the illumination device according to the present embodiment, LEDs are used as illumination means, and the number of LEDs corresponds to the number of articles B for display. You can change the color, intensity, etc. Further, since the illumination control as described above can be performed in correspondence with each of the exhibition article groups b1, b2, and b3, it is possible to have an illumination effect appealing to the visual perception of the article viewer. In addition, it is possible to alternately control 3 to 4 articles for display as one unit, and an illumination effect and an energy saving effect can be obtained.

  (10) The LED light emitted from the LED 40 mounted on the first surface 30a of the substrate 30 and the LED 41 mounted on the second surface 30b is attached not only to the display article B but also to the stage 25. Since the illumination of the display unit 26 and the contour illumination of the push button 8 for selecting an article attached to the front panel 7 are possible, a dedicated illumination device is not necessary for the push button 8 and the display unit 26, and the cost is low. Can be achieved.

It is a front view which shows the whole vending machine provided with the illuminating device of the article for exhibition which concerns on embodiment of this invention.
