Description

[Detailed description of the invention] [Industrial application field] The present invention relates to lighting equipment for illuminating paintings, etc. exhibited in museums, galleries, etc.

[Conventional technology]

Conventional lighting for paintings, etc. in museums, galleries, etc. has a large difference in illuminance between the top and bottom of the work, and this is especially noticeable in large-scale works, etc., which are over 100 in size.

In addition, there were many inconveniences such as the light source directly entering the viewer's eyes and causing glare to the viewer.

[Problem that the invention attempts to solve]

In view of the above-mentioned problems, the present invention is a lighting equipment that uniformly illuminates a painting, etc., and does not cause the viewer of the painting to feel glare, and also serves as a security equipment to protect the painting from damage.

[Means for solving problems]

In order to solve the above problems, the present invention provides a foothold on the floor at a predetermined distance from the wall on which paintings, etc. are displayed, and a lighting fixture having a parawegular louver on the front is installed on the wall and at a distance slightly further from the wall than the foothold. The light source of the lighting equipment is made up of multiple fluorescent lamps arranged in parallel, and the fluorescent lamps are arranged densely as they move away from the wall. The illuminance above was made uniform.

The stop is a floor that smoothly rises parallel to the wall at least at a distance that cannot be reached from the paintings on display, and a lighting duct with a dimmer that accommodates spot lighting equipment on the wall side. It is preferable to provide

[Effect]

According to the present invention, since the lighting equipment is arranged at a predetermined angle to the wall and the light sources are arranged more closely as the distance from the wall increases, the illuminance of paintings, etc. on the wall becomes almost uniform.

Moreover, since the front surface of the lighting equipment is provided with a parawegian louver, the illuminated part and the shielded part can be clearly distinguished. Therefore, the feet of the viewer standing near the stop are brightly illuminated, but the light source does not enter the viewer's eyes, and the painting is less likely to be damaged because the stop is located at a distance that is out of reach of the painting.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic sectional view of one embodiment of the present invention;
The figure is an enlarged cross-sectional view of the para wedge louver.
In the figure, reference numeral 10 denotes a lighting fixture, 12 a pallet wedge louver attached to the front surface of the lighting fixture, and 14 a fluorescent lamp arranged in parallel at predetermined irregular intervals.

20 is the ceiling of the museum, 22 is the same wall, and 24 is the same floor. Reference numeral 26 is a footrest formed so as to roll up the floor 24, and is formed at a distance so that the painting is not exposed to glare when viewing it, and the painting is not easily damaged. P is a painting hung on the wall 22.

The lighting fixture 10 is housed in a recess provided in the ceiling 20. In this embodiment, the mounting angle is set relative to the horizontal plane so that the lighting part illuminates an area slightly farther away from the wall 22 than the foothold 26.
It is set at 30°.

The para wedge louvers 12 have reflective surfaces formed in a parabolic shape and are arranged in a lattice pattern (see FIG. 2). This reflects and passes the light from the light source so that the boundary between the illuminated part and the shielded part appears very clearly. The angle that this boundary makes with the front surface of the palate wedge louver 12 is generally 135 degrees.

The fluorescent lamps 14 are arranged more densely as they get farther from the wall 22, so that the difference in illuminance between the upper and lower surfaces of the wall 22, especially the area where paintings are displayed, becomes smaller.

A lighting duct 30 is provided on the wall 22 side of the foothold 26, and an incandescent lamp 32 with a reflective coating is housed in the lighting duct 30. A long-pile carpet or the like is placed between the foothold 26 and the wall 22 to prevent the viewer from trying to step over the foothold 26.

According to the lighting equipment having the above configuration, the viewer will naturally stop right in front of the stop 26 and appreciate the painting. This position is at the minimum necessary distance from the painting P for security reasons, and the illumination light from the painting P does not enter the field of view, allowing the viewer to enjoy the viewing experience comfortably without being exposed to glare. .

The lighting equipment is not limited to the embodiments described above. For example, the mounting position of the lighting fixture 10,
The mounting angle and position of the stop 26 will vary depending on the size of the painting to be illuminated. The shape of the foot stop 26 is not limited to the illustrated embodiment, and various modifications are possible.

〔effect〕

According to the lighting equipment of the present invention having the above-mentioned configuration, the viewer naturally stops right before the viewer stops and admires the painting. In this position, the viewer's eyes are located within the shielded portion and are therefore not subject to glare from the illumination light.

Additionally, the lighting equipment in this facility illuminates the painting with almost uniform illuminance from top to bottom, allowing the painting to be viewed in a more natural state.

Claims (1)

[Scope of Claim for Utility Model Registration] A lighting fixture 10 having a pallet wedge louver 12 on the front is attached to a ceiling 20 near a wall 22 facing toward the wall 22, and a foothold 26 is provided on a floor 24 at a predetermined distance from the wall 22. In the lighting equipment, the lighting fixture 10 is placed closer to the wall 2 than the foothold 26.
The light source of the lighting fixture 10 is composed of a plurality of fluorescent lamps 14 arranged in parallel, and the fluorescent lamps 14 are arranged so as to illuminate the wall 22 with uniform illuminance. Lighting equipment for paintings, etc., characterized in that the lighting equipment is arranged densely as it goes away from the wall 22.
