Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a daylighting plate for a daylighting device, and particularly to a daylighting plate that is an improvement on synthetic resin daylighting plates.

[Conventional technology]

Conventional lighting panels have often been glass panels reinforced with metal wires, but in recent years, panels made of synthetic resin have been widely used.

Especially among synthetic resin daylighting panels, acrylic resin ones
Those made of FRP resin are widely used.

[Problem that the invention attempts to solve]

However, when the thickness of the acrylic resin plate is reduced, cracks occur around the perforation during the drilling process for attaching the lighting device to the support frame. Therefore, if the thickness of the plate was made thicker, it would not be possible to perform perforation, and the technique for attaching the plate to the support frame would be extremely difficult.

Additionally, those made of FRP resin are strong and easy to process even when the board thickness is reduced, but if the board is directly exposed to sunlight or rain for a long period of time,
Due to changes over time, the resin portion eroded, the glass surface became exposed, and the surface of the plate material became a rough surface. Dust adhered to such a surface and was difficult to remove, spoiling the aesthetic appearance.

[Means for solving problems]

In view of the various problems of the conventional synthetic resin daylighting plates mentioned above, the present invention uses an acrylic resin daylighting plate as a substrate to provide a daylighting plate that is robust and easy to process even when the plate thickness is reduced. The purpose is to

In order to achieve this purpose, the present invention is a lighting device that is installed in a roof opening and brings in natural light indoors.
It is characterized by being integrally fixed.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a lighting plate, and this lighting plate 1 has a glass fiber material 3 integrally fixed to the inner surface (lower surface) of an acrylic resin substrate 2 formed in the shape of a semicircular dome.

This will be explained in more detail with reference to FIG.

A rough surface 4 having various shapes such as an uneven pattern or a line pattern is formed on the inner surface of the acrylic resin substrate 2. Also,
Spray or directly apply molten FRP resin to one side of the glass fiber material 3.
Impregnate the FRP resin and apply the FRP resin adhesion surface to the substrate 2.
It is pasted on the rough surface 4 of. FRP resin is the substrate 2
The FRP resin penetrates into the rough surface 4 of the substrate 2 and hardens, thereby integrally fixing the substrate 2 and the glass fiber material 3.

Although the substrate 2 is shown in a dome shape,
The shape may be a flat plate or other shape.

The rough surface 4 formed on the substrate 2 is formed after the substrate 2 is processed into the shape of the lighting plate 1, but if it is technically possible, the rough surface 4 can be formed directly at the time of manufacturing the substrate 2. The substrate 2 may be processed and formed as the lighting plate 1.

Furthermore, the molten FRP resin may be applied directly to the rough surface 4 of the substrate 2, and the glass fiber material 3 may be attached to this applied surface.

[Effects of the invention] As described above, according to the invention, since the glass fiber material 3 is integrally fixed to the inner surface of the acrylic resin substrate 2 via the FRP resin, the substrate 2
Reinforced with FRP resin and glass fiber material 3,
It is strong even when the plate thickness is reduced, and no cracking occurs even during drilling.

Furthermore, since the FRP resin is not directly exposed to sunlight or rain, the resin portion is not eroded due to changes over time, making it ideal as a reinforcing material for the substrate 2.
