Description

  The present invention relates to a showcase, particularly a showcase with built-in lighting.

As a means of displaying jewelry, precious metal products, arts and crafts, etc., and viewing them, a cylindrical showcase with the bottom facing up is widely used.
In such a shoe case, in order to effectively visually recognize an object (product) displayed inside, an illumination means for illuminating the object or its periphery is used.
As such illumination means, a downlight is often arranged at an upper position away from the showcase, but the light is reflected on the top of the showcase and the light is reflected, or the light is blocked when the observer looks into it. There was a problem.

Therefore, conventionally, downlighting is performed with a halogen lamp from the top of the showcase, but a box-shaped illuminator incorporating a support member including a halogen lamp and a socket is attached in the form of a canopy.
In this structure, a large canopy as an illuminator is placed on the top of the showcase, so that the overall design is restricted and the design is restricted, and the object cannot be seen from above the top. was there. In addition, a pipe-shaped frame that conceals the wires is required to guide the wires from the case base at the bottom of the showcase to supply power to the halogen lamp, thereby impairing the appearance of the showcase and the visibility of objects. There was also a problem to do.
As another type, there is a structure that arranges a fluorescent lamp supported by a pole directly under the top of the showcase, but because the lamp is exposed and there is an upper pole, the smart appearance is not good, the showcase The problem was that the visibility was not good due to the light being reflected on the screen, and the temperature inside the showcase increased due to heat dissipation.

The present invention has been made to solve the above-mentioned problems, and its purpose is to be smart and clean, with a good appearance, good visibility, and extremely effective. An object of the present invention is to provide a showcase with a built-in illumination that can illuminate an object and hardly raises the temperature inside the case.
In addition to the above object, a second object of the present invention is to provide a lighting-incorporated showcase that does not have a special frame for power supply wiring and can improve the visibility and appearance of an object. .

  In order to achieve the above object, the present invention provides a flat lighting device in which a card-type LED lamp is incorporated in a ceiling wall and / or a wall of a transparent case body having a ceiling wall and a wall.

The boulder portion 9 has a connector 90 to which the power supply wiring 8 is connected, and is provided with a parallel rail frame 91 for locking the side portion of the card-type LED module in front of the connector 90. A guide plate 70 for guiding the power supply wiring 5 to the through hole 602 is fixed to the lower surface of the longitudinal end portion 8. The guide plate 70 also functions as a reinforcing material when the strip plate support 8 is fitted to the flat casing 6.

The card-type LED lamp body 5 is known per se, and as shown in FIG. 7, light emission is made such that a large number of, for example, 64 LEDs and phosphors are arranged in a dot pattern on a heat dissipation substrate 50 integrally formed with a wiring pattern. The portion 51 is provided in a layered manner, and a pattern-like terminal portion 52 is provided on one side of the heat radiating substrate, a lens is provided on the surface of the light emitting portion, and a heat conductive material such as aluminum is provided on the back surface of the heat radiating substrate 50. A heat radiating portion 501 made of a good metal is provided in layers.

When the card-type LED lamp body 5 is pushed in from the open side of the yoke-shaped parallel rail frame 91, the terminal portion 52 is connected to the connector 90, and at the same time, the heat radiating portion 501 on the back surface is in close contact with the lower surface of the belt-like support body 7. Both sides are locked so as to. Thereby, the heat radiation from the card-type LED lamp body 5 is transmitted to the strip plate-like support body 7, and since the volume of the strip plate-like support body 7 is large, it can be diffused efficiently. Further, the belt-like support 7 also functions as a cover.

The power supply wiring 8 led out from the flat illuminating device 4 can be used as shown in FIGS. 3, 8, and 9 without using a through-frame or pipe as in the prior art.
