Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display case for displaying artifacts,

The present invention relates to a museum display case for exhibiting artifacts that can be installed and maintained in the outside of a display case and a local illumination. The display space is divided into an exhibition space where artifacts are displayed in a display case, To a museum showcase for exhibiting artifacts that can install and maintain general lighting and local illumination from the outside of a showcase that allows replacement / repair of local illumination and general lighting outside the showcase, and installation / angle adjustment.

In general, artifacts are kept in museums equipped with security facilities, and artifacts stored in museums are displayed in a showcase where the inside is visible for public viewing.

The above-mentioned display case is configured to prevent discoloration of various artifacts and propagation of fungi in an environment where there is no change in temperature and humidity. At least one of the front and left and right sides of the display case can be opened and closed so that the stored state of the artifacts displayed on the display case can be checked or the artifacts can be replaced if necessary.

In addition, a museum showcase where artifacts are displayed is installed with general lighting or local illumination for efficiency of viewing.

The main lighting is installed in the upper illuminating space of the display case so that spectators can see the artifacts by illuminating the entire inside of the display case. Fluorescent lamps, halogen lamps, lights using optical cables, LCD lamps, LED lamps and the like are used.

The local illumination is used to intensify the light in a specific range to improve the spectator's concentration of attention on the artifact, and various kinds of local illumination lamps such as track illumination, optical fiber illumination and the like are used.

However, the local illumination of the optical fiber illumination type is fixed in its position and there is a limitation in the angle adjustment, so that the light is not properly reflected on the artifacts displayed, so that the attention concentration and the display effect of the viewer are degraded.

In addition, the track illumination is located within the illumination space. However, for light source replacement and troubleshooting, angle adjustment and installation, the artisan goes directly into the exhibition space within the exhibition space where the artifact is installed, It has to be taken out and replaced and repaired, resulting in serious danger to the safety of artifacts.

In order to adjust the angle of illumination of the track illumination, it is necessary for the operator to change the angle of the light source such that the light source is replaced or repaired , It is necessary to enter the display space in the display case to directly adjust the angle of illumination, which makes it impossible to secure the stability of the displayed artifact.

In order to secure the exhibition space, the museum showcase is designed to have a narrow space for lighting. Therefore, in order to replace the main lighting located in the lighting space and repair the malfunction, the operator must climb up the ladder and open the door Replacing the light source and repairing it should be done by putting only the arm into the lighting space. However, all of the fluorescent lamps, halogen lamps, and the like, which are used as light sources for the first half of the entirety, are provided with a predetermined size, which makes the operation very difficult and laborious in a narrow illumination space.

In addition, in order to solve the problem of the above-mentioned general lighting, there is a system in which a main lighting installed in an illumination space is moved to the outside of a display case in a slide manner, In such a configuration, since a separate slide moving means for moving the overall light to the outside is installed in the illumination space, the size of the illumination space becomes large, which causes a problem that the size of the exhibition space becomes narrow, .

In addition, there is also a museum showcase 100 in which an LCD illumination lamp or an LED illumination lamp 101 is used as the overall illumination to improve the space utilization of the illumination space. However, the LCD illumination lamp or the LED illumination lamp 101 are all composed of point light sources In order to prevent the viewer from glare when the light is directly irradiated on the artifact, an acrylic light-transmitting plate capable of diffusing light at a predetermined distance from the LCD lighting lamp or the LED lighting light 101 It is necessary to install the barrister 102 and the like and to secure the space for the replacement operation of the LCD illumination lamp or the LED illumination lamp 101 so that the tracked local illumination 103 is installed under the general illumination in the illumination space with the local illumination There is a problem that can not be done.

That is, when the track type local illumination is installed in the conventional museum display case using the LCD illumination lamp or the LED illumination light 101 as the general illumination, the illumination check door size (height) becomes large, and the glass height becomes relatively low There is a problem that the field of view of a large artifact is narrowed.

In addition, when the track type local illumination is installed in the local illumination of the conventional museum showcase using the LCD illumination lamp or the LED illumination lamp 101 as the overall illumination, as shown in FIG. 7, Local illumination must be installed, which causes problems such as replacement of local illumination and repair work in the exhibition space.
