Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to the improvement of outdoor lighting fixtures that are attached to the exterior walls of buildings such as department stores and hotels.

<Conventional technology> A mirror plate whose glass surface is coated with a special multilayer vacuum-deposited film that separates light into transmission and reflection is called a dichroic mirror and is mainly attached to indoor lighting equipment in various stores. It is used. According to this, when light is received by the mirror plate, a certain color light is transmitted and another specific color light is reflected, so that a projection woven from the two types of color light is created. The pattern has the advantage of producing interesting and new lighting effects.

<Problem to be solved by the invention> However, in the conventional mirror plate, the vapor-deposited film for light decomposition is only coated on one side of the glass, so to speak, in a completely exposed state. Not only when used in indoor lighting equipment, but when used as a component of outdoor lighting equipment, it is exposed to sunlight, wind and rain, exhaust gas, salt, and other natural conditions for a long time. The deposited film will be eroded, leading to deterioration in the reliability and durability of the lighting fixture.

Furthermore, during periodic inspection and cleaning of lighting equipment, the vapor deposited film is likely to be accidentally damaged or peeled off by operating tools or liquids used to remove dust. Furthermore, in the event of an earthquake or typhoon, and the lighting equipment falls, the mirror plate is made of a single piece of glass, which can easily scatter into sharp pieces, which is extremely dangerous. Therefore, there are restrictions on the installation location.

<Means for solving the problem> The present invention is intended to improve such problems, and for this purpose, it has a mounting base that is attached and fixed to the external wall of the building, and a mounting base that is attached to the external wall of the building. In an outdoor lighting fixture, the mounting base is provided with a mirror plate that is attached and held in a vertical relationship, and the mounting base is rotatably operable to change the installation position of the mirror plate in an up-and-down manner. , in order to reflect light of a certain color and transmit light of another specific color when light is projected onto it.
When bonding and integrating a multilayer vacuum-deposited film that acts on photodecomposition and a pair of glasses that sandwich it in a sealed state, one of the pair of glasses is coated with a multilayer vacuum-deposited film with a smaller area than the above-mentioned pair of glasses. The vapor deposited film is set so that the vapor deposited film is not exposed even from the end surface of the paired glass by heat-pressing the other side of the pair of glasses via an adhesive film so as to cover the vapor deposited film. It is.

<Example> Hereinafter, the specific configuration of the present invention will be described in detail based on the illustrated example. Figures 1 to 4 show the outdoor lighting equipment according to the present invention and its installation state, and 11 is a building M. It is a mounting base for attaching to the outer wall surface of the holder, and is made of a metal disc in which a pair of opposing rotation guide elongated holes 12 are opened. Then, the anchor bolt 13 is driven into the building M while passing through this, and the anchor bolt 13 is stably fixed to the outer wall surface of the building M via the fastening nut 14 thereof.

In that case, by rotating the metal disk along the arc-shaped opening locus of the guide slot 12, the installation posture of the mirror plate G, which will be described later, can be adjusted in a undulating manner as shown by the chain line in FIG. It can be changed. However, as long as the mounting base 11 has a structure that can be changed, it may be assembled from a rigid material other than a metal disk.

Reference numeral 15 denotes a holding frame for the mirror plate G, which has an overall rectangular outline and is made up of a frame body 15a that is assembled and integrated into a U-shape, and a cover frame piece 15b that closes an open portion on one side of the frame body 15a. At the same time, the frame body 15a is welded to the mounting base 11 via a plurality of support stays 16. The holding frame 1
5 is the cover frame piece 15b, as is clear from FIG.
The mirror plate G is fitted into the frame main body 15a, and is restrained and fixed by the cover frame piece 15b.

When the mounting base 11 is attached and fixed to the outer wall surface of the building M, the mirror plate G is maintained vertically from the outer wall surface.
Reference numeral 17 denotes an elastic packing inserted within the holding frame 15, which acts as a buffer to prevent the mirror plate G from wobbling. 18 is a screw for fixing the cover frame piece 15b to the frame body 15a;
By removing this, it is also possible to replace the mirror plate G. In the illustrated example, the mirror plate G and its holding frame 15 are set to have a rectangular outline, but they may of course be formed into other polygonal or circular shapes.

In the mirror plate G, as shown in FIGS. 5 and 6, a special multilayer vacuum-deposited film 19 that decomposes the light is sealed between the pair of glasses 20 and 21. No. 20 and 21 are not exposed at all from the butt sides.

That is, when the vapor deposited film 19 receives light projection,
For example, yellow, a specific color, is generated as reflected light, and a different specific color, blue, is generated as transmitted light. , which is integrally coated on one glass 20. Moreover, the vapor deposited film 1
In particular, the size area of the glass 9 is set smaller than that of the glass 20 by a certain dimension L.

Then, the other glass 21 having the same size is placed so as to completely cover the deposited film 19.
However, a thin adhesive film 22 of approximately 0.2 to 0.5 mm is used.
It is heat-pressed and bonded to one of the coated glasses 20 via the above-mentioned. At the time of heating and pressurizing, the adhesive film 22 becomes a molten film and closes the circumferential gap T by the above-mentioned constant dimension L, so that the vapor deposited film 19 is
There is nothing exposed from the end surface of 0.21.

The pair of glasses 20 and 21 can have different thicknesses, but in that case, it is desirable that the thinner glass 20 be coated with the vapor deposited film 19 in advance. This is because coating can be performed more easily than vice versa.

<Function> When using the outdoor lighting equipment equipped with the mirror plate G as described above, it can be attached to a department store, hotel, or other building M where a large number of people gather, by using the mounting base 11 as shown in FIG. The mirror plate G is attached and fixed to the outer wall surface of the mirror plate G, and light in the direction of arrow A is irradiated onto the mirror plate G from a suitable location such as the rooftop or the ground using a large floodlight 23 or a spotlight.

Then, due to the photodecomposition effect of the vapor deposited film 19, for example, the yellow reflected light B will be refractively diverged from the mirror plate G, and at the same time, another blue transmitted light C will also be generated in a straight line. Therefore, a projected pattern woven from the two types of colored lights can be used as an outdoor lighting effect.

In that case, even if the projector 23 is fixedly installed at a certain location, the projection direction of the light will be different from the mounting base 1.
The above-mentioned illumination can be changed and adjusted in advance by the rotation operation of 1, and yellow as reflected light B and blue as transmitted light C can also be changed to various other colors at will. The effect is actually even more interesting and varied.

<Effects of the invention> As described above, the present invention includes a mounting base 11 that is mounted and fixed on the outer wall of the building M, and a mirror that is mounted and held on the mounting base 11 in a relationship that stands vertically from the outer wall of the building M. In the outdoor lighting equipment, the mounting base 11 is configured to be rotatably operable to change the installation position of the mirror plate G in an up and down manner, In order to reflect a certain color light and transmit another specific color light,
When bonding and integrating the multilayer vacuum-deposited film 19 that acts on photolysis with the pair of glasses 20 and 21 sandwiching it in a sealed state, a multilayer vacuum with a smaller area is attached to one of the pair of glasses 20 and 21. By coating the vapor deposited film 19 and heat-pressing the other pair of glasses 20 and 21 through the adhesive film 22 so as to cover the vapor deposited film 19, the vapor deposited film 19 is attached to the paired glasses 20 and 21. Since it is set so that it is not exposed even from the wood end surface, the problems of the prior art described at the beginning can be easily and completely solved, and the reliability and durability of the lighting equipment can be significantly improved.

In other words, the special multilayer vacuum-deposited film 19 that acts on the photolysis of the mirror plate G is formed by the pair of glasses 20, 2.
1, and are integrated with the adhesive film 22, so even if it is attached to a lighting equipment and used outdoors, it will not be exposed to sunlight, wind, rain, etc. Since it is not adversely affected by the natural conditions of the lamp and does not require dust removal work, there is no risk of it being damaged or peeled off, and the durability of the entire lighting equipment including the mirror plate G can be improved, making it always excellent. This allows you to maintain your lighting equipment.

Moreover, the mirror plate G is a pair of glasses 20, 21
The walls are made thicker, and an adhesive film 22 is also interposed between them, so it has excellent physical strength against cracks and cracks even when subjected to vibrations and shocks, and is also resistant to earthquakes and typhoons. Even if the light fixture were to fall together with the lighting equipment during an emergency, the adhesive film 22 prevents it from scattering as small, sharp pieces, making it extremely safe.
