Description

  The present invention relates to a rod-shaped illuminator and an exhibition apparatus using the rod-shaped illuminator, and more particularly, a rod-shaped illuminator capable of spot illumination, and a peeping type used in a museum, an art gallery or a store using the rod-shaped illuminator. This is related to the exhibition equipment.

  Various types of viewing-type display devices have been provided in the past, where an exhibition space is provided inside, and at least the upper part or the entire periphery thereof is covered with a light-transmitting glass plate. A structure that can be freely opened and closed is common. In addition, as shown in Patent Document 1, it can be used alone, and when displaying a long display such as a scroll, a plurality of display devices are connected side by side to provide an exhibition space for each display device. A structure that can be used continuously is also provided. Furthermore, art and antique documents displayed in the exhibition device must be strictly controlled for humidity and temperature in order to enhance their preservation, so the exhibition space can be air-conditioned by shutting off the outside air. Yes.

  In the exhibition space, there is provided an illuminating device for illuminating the exhibit, and the present applicant provides a fluorescent lamp along the upper rear part of the exhibition space, and sets a plurality of optical fiber illumination irradiation openings at the front part. The display device with illumination of the structure arranged in this way is provided. Here, if too bright lighting fixtures are used, the amount of UV radiation will increase, and the historically valuable exhibits will be light-degraded and altered, so it will be bright in the exhibition equipment used in museums and galleries. We use soft lighting fixtures that suppress this. Since both conventional fluorescent lights and fiber optic lights are diffuse lights, the exhibits placed at a position away from the luminaire tend to be darker than the rear part or the front part. Therefore, spot lighting is usually used to emphasize and illuminate the exhibits. Although it is considered that a lens is provided at the irradiation port of the above-described optical fiber illumination to collect light, the position of the irradiation port of the optical fiber illumination is low, so that in principle, a shadow is produced on the exhibit and the illumination effect is small. If a new spot illuminator is installed at a slightly higher position at the rear or front of the exhibition space, the spot illuminator will not only interfere with the display, but will also illuminate from a position away from the exhibit. It is necessary to adjust the angle and spot diameter.

Patent Document 2 is an exhibition device having a structure surrounded by a transparent glass plate or a transparent synthetic resin plate, but the other end of the light guide having one end connected to the light source provided in the lower base unit, An illuminating device having a structure in which a hollow column of an illuminating unit of a flexible pipe structure having an irradiation unit lens at a tip thereof is connected to the socket in an upright state is connected to a socket provided at a corner portion of a floor surface of an exhibition space. ing. Although this lighting device can bend the hollow strut of the flexible pipe structure to arbitrarily set the direction of the irradiation unit lens and can effectively illuminate from the periphery of the exhibit, the diameter of the hollow strut of the flexible pipe structure is large, Moreover, since the front-end | tip part which has an irradiation part lens is comparatively large, it may become obstructive.
