DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display case which is arranged in an art museum, a museum, and the like, and in which an exhibit such as arts and crafts and paintings can be stored.

[0002]

2. Description of the Related Art A display case of this type is generally provided with a substantially rectangular parallelepiped glass case main body having a storage space in which an object to be displayed can be stored, and an upper part of the case main body, and has a lighting inside. The lighting device includes a lighting box made of steel in which instruments are stored, and a base for supporting the case body on a floor surface.

[0003] By the way, many of the exhibits stored in the display case have high cultural value, such as works of art and paintings. Great care is taken in the temperature and humidity of the building.

[0004] In particular, a lighting fixture such as a fluorescent lamp used to illuminate an exhibit emits heat during use. Therefore, when the lighting fixture is arranged in the storage space, the temperature in the storage space rises during illumination. As a result, the temperature rise may lower the relative humidity in the storage space, which may adversely affect the preservation of cultural properties. Therefore, conventionally, a steel lighting box is provided outside the case main body, and a lighting fixture is built in the lighting box. This lighting box is, for example, a box-shaped one arranged above the case main body so as to substantially cover the upper surface thereof, and is provided outside the case main body in a state where the storage space for the lighting fixture and the case main body is shut off. In addition, the display is illuminated in a state in which a rise in temperature and a decrease in humidity in the storage space due to heat generated by the lighting equipment are prevented.

[0005]

However, with the above-described structure, the lighting box is located at a position outside the case body that is very noticeable when viewed. The appearance of the display case is particularly important for its purpose, and such a structure that impairs the appearance is not preferable.

On the other hand, it is also conceivable to arrange a light source in the base and illuminate an exhibit through an optical fiber routed from the light source into the case body. Optical fiber is
Since the heat is hardly generated, the problem of the temperature rise in the storage space can be solved, but there is a problem that the cost is very high.
Therefore, at present, there is a demand for a structure capable of illuminating an exhibit with an inexpensive and simple structure and without impairing the appearance of the display case.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a lighting housing for housing a lighting fixture in a state of being shielded from air in a housing space in a case body. By exhausting the air heated by the lighting fixture in the lighting container to the outside by the exhaust means, it is possible to keep the appearance of the display case good and to minimize the influence of heat exerted on the storage space by the lighting fixture. ing.
