Description

[Detailed Description of the Invention] This invention relates to a lighting board for architecture or fittings that allows light to pass through.

Traditional buildings either receive light through glass windows or glass doors, or
Several sides of the building were covered with glass or transparent synthetic resin boards, allowing sunlight to enter directly through the glass or transparent synthetic resin boards, but glass was easily broken even by a small impact, and synthetic resin boards were susceptible to heat and easily damaged. there were.

Therefore, this idea was made by drilling holes in a metal plate that is resistant to heat and difficult to break, sandwiching the metal plate with these holes with a synthetic resin plate that is weak in heat, and letting light in through the small holes in the metal plate. By devising a lighting board, we succeeded in producing a lighting board with strong durability that could not be obtained with conventional glass or synthetic resin boards.

Next, the structure of the lighting plate according to the present invention will be explained with reference to drawings of an embodiment. One of two identical flat metal plates 1 and 1' is made into a back metal plate 1 in which holes 2 of an appropriate size are bored in an orderly manner, The other side is a back metal plate 1' having a large number of small holes 2' with a smaller diameter than the holes 2 of the back metal plate 1, and a transparent transparent plate having the same length and width as the front and back metal plates 1, 1'. A back metal plate 1 with holes 2 drilled in the front surface 3a of the synthetic resin plate 3 has small holes 2' in the back surface 3b.
A sandwich structure is provided in which a back metal plate 1' with holes is attached, a synthetic resin plate 3, a back metal plate 1 attached to its front surface 3a, and a back metal plate 1' attached to its back surface 3b. The metal plates 1 and 1' are mainly made of light metal such as aluminum and aluminum alloy that easily reflect light, and the holes 2 and small holes 2' formed in the metal plates 1 and 1' are circular or elliptical. The metal plates 1, 1' may have various shapes such as triangular, rectangular, etc., and may be perforated facing each other with the synthetic resin plate 3 interposed therebetween, or may be perforated at different angles, so that the metal plates 1, 1' are entirely covered or partially formed. The metal plate 1
, 1' and the synthetic resin plate 3 are attached using adhesive A as shown in FIG. 4, or by thermocompression bonding as shown in FIG. The molten resin II is placed between the opposing metal plates 1 and 1' at appropriate intervals
I was poured into the metal plates 1, 1' by solidification of the molten resin III that had flowed into the small holes 2゜2' of the metal plates 1, 1'.
The small holes 2 of the metal plates 1, 1' can be formed by attaching the synthetic resin plate 3 to the holder B, which is attached to the metal plates 1, 1' at an appropriate distance as shown in FIG. , 2' are provided, the small holes 2, 2' of the metal plates 1, 1' are closed with the protrusions of the holder B, and the melt is inserted into the small holes 2, 2' of the metal plates 1, 1'. Resin I
A synthetic resin plate 3 is formed between the metal plates 1 and 1' to prevent II from flowing in.

Since the proposed daylighting board has the above-mentioned structure, if it is used as a mirror board for fittings such as shoji or shutters, or as a wainscot, or as an exterior material for a building, or as a partition board or a blind board, it can be used as a daylighting board. Of the light R irradiated toward (), the light γ irradiated toward the hole 2 of the back metal plate 1 travels straight into the transparent synthetic resin plate 3 and is attached to the back surface 3b of the synthetic resin plate 3. The back metal plate 1' prevents the light from going straight, and the light is repeatedly reflected between the front and back metal plates 1 and 1', and is irradiated into the room through the small hole 2' of the back metal plate 1', or is drilled in the straight direction of the light γ. Back metal plate 1'
The room is irradiated through the small hole 2'.

In addition, even if wind and rain blows on the fittings or exterior parts to which the lighting board ■ is installed, the hole 2 drilled in the back metal plate 1 of the lighting board ■ will not interfere with the synthetic resin plate 3 installed between the metal plates 1 and 1'. Wind and rain will not pass through the lighting board.

In addition, the metal plate 1 is placed on the front and back surfaces 3a and 3b of the synthetic resin plate 3.
After attaching ゜1', a similar lighting plate ■ can be obtained by drilling holes 2 and small holes 2' within arbitrary ranges of both metal plates 1 and 1'. One side of is made rough surface 1a, 1a',
It is also possible to strengthen the adhesion between the metal plates 1, 1' and the synthetic resin plate 3.

Therefore, the lighting board of this proposal can be used as a wainscot or mirror board for fittings,
When used as exterior boards or blind boards for buildings, it will not break or break like conventional glass, will not get damaged like synthetic resin boards for daylighting, and has significantly improved heat resistance, making it highly durable as daylighting boards. will also improve dramatically.

Moreover, the proposed lighting board can be adjusted by adjusting the drilling range of the holes and small holes in the metal plate that constitutes the lighting board, and the drilling density of both holes.
You can freely manufacture lighting boards that let in a small amount of light to lighting boards that let in a lot of light, and you can also use colored and transparent synthetic resin boards, and change the shape and arrangement of the holes and small holes. In addition to the above-mentioned features that make it possible to improve durability and diversify decorations, the proposed lighting board has a remarkable practical effect, such as the ability to form many types of lighting boards with different decorative effects by changing the It is something to play.
