[0097] Although FIGS. 7 to 9 show only three light-emitting diodes, there may be more than three light-emitting diodes mounted on the first main surface 64 of the substrate 62, or there may be only one or two light-emitting diodes. are mounted, or there may be only one or two light-emitting diodes.

[0098] FIG. 8 shows a schematic exploded perspective view of another grained laminated glass plate 81. FIG. 9 shows a schematic cross-sectional view taken along line B-B' of the grained laminated glass plate 81 of FIG. 8. is shown.

[0099] In this embodiment, the grained laminated glass plate 81 includes a first glass sheet 83 joined to a second glass sheet 85 by an intermediate layer structure 87. The intermediate layer structure 87 is composed of three adhesive intermediate layer material sheets (i.e., PVB, EVA, or a combination of those layers) 89, 91, 93. The first adhesive intermediate layer material sheet 89 has the same extent as the first glass sheet. The second adhesive intermediate layer material sheet 91 has the same extent as the second glass sheet 85. has. The third adhesive intermediate layer material sheet 93 is disposed between the first and second intermediate layer material sheets 89, 91 and has a cutout region therein for accommodating the lighting device 60. The cutout region is along one edge of the third adhesive intermediate layer material sheet, and the other three edges are parallel to the respective edges of the first and second adhesive intermediate layer material sheets. is arranged and has a cutout region therein for accommodating the lighting device 60. The cutout region is along one edge of the third adhesive intermediate layer material sheet, and the other three edges are parallel to the respective edges of the first and second adhesive intermediate layer material sheets.

[0100] FIG. 8 is a stack of unbonded components that are bonded together using a conventional bonding process, for example, using appropriate high temperature and high pressure, to form the final grained laminated glass plate. It is a figure showing what can manufacture the glazing laminated glass plate 81.

[0101] As shown in Fig. 9, in the final glazing laminated glass plate 81, the electric device 60 is between the first and second adhesive intermediate layer sheets 89, 91 and is disposed in the cutout region of the third adhesive intermediate layer sheet 93. With such a structure, (compared with the two-layer adhesive intermediate layer structure ) since there is an extra layer of the third adhesive intermediate layer material, it becomes easier to accommodate the thickness of the electric device 60 between the first adhesive intermediate layer sheet and the second adhesive intermediate layer sheet, and the lamination becomes simpler.

[0102] In the final glazing laminated glass plate 81, the first adhesive intermediate layer sheet 89 is in direct contact adjacent to the first glass sheet 83, and the second adhesive intermediate layer sheet 91 is in direct contact adjacent to the second glass sheet 85. The third adhesive intermediate layer sheet 93 is in direct contact with both the first and second adhesive intermediate layer sheets 89, 91.

[0103] Fig. 9 is a schematic cross-sectional view taken along line B-B' of Fig. 8, and shows a state where the portion 72 extends beyond the outer periphery of the laminated glazing 81 so that power can be supplied to the lighting device 60 via the electrical contacts 68, 69.

[0104] At least one of the first, second, and third adhesive intermediate layer sheets 89, 91, 93 can be PVB or EVA.

[0105] The first sheet glass 83 has a dot array on a part of its main surface facing the first sheet adhesive intermediate layer material 89, as shown in Figs. 3 and 4 for example. Each has a dot array There may be three separate areas (for diffusing the light from respective light-emitting diodes 65, 66, 67), or there may be one area having a dot array for diffusing the light from all of the three light-emitting diodes 65, 66, 67. There may be two areas each having a dot array for diffusing the light from light-emitting diodes 65, 66 and 67 or 65 and 66, 67 or 66 and 65, 67. The first adhesive intermediate layer sheet 89 may be translucent to help further diffuse the light emitted from the light-emitting diodes 66, 66, 67. In one embodiment, the first adhesive intermediate layer sheet is configured in the same manner as the third adhesive intermediate layer sheet 93 as shown in FIG. 8. That is, the first adhesive intermediate layer sheet may have cutout areas therein. A translucent intermediate layer sheet may be disposed in the cutout areas, while the first adhesive intermediate layer sheet having the cutout areas therein may be a conventional non-translucent adhesive intermediate layer such as PVB. A plan view helping to explain such an embodiment is shown in FIG. 10. FIG. 10 is a schematic plan view of a first adhesive intermediate layer sheet 189 that may be used in place of the first adhesive intermediate layer sheet 89 shown in FIGS. 8 and 9. The first adhesive intermediate layer sheet 189 has a first portion 189a of conventional PVB (i.e., transparent PVB) having a cutout area 189b therein. Disposed in the cutout area 189b is a translucent PVB sheet 189c. The translucent PVB sheet 189c is in the same plane as the first portion 189a.

[0109]

[0110] ​​​​​​​​​​​​​ Below the first intermediate layer material sheet 189 is disposed a lighting device 160 similar to the lighting device 60, and there are six light emitting diodes on the circuit board instead of just three.

[0111] FIG. 11 shows a schematic plan view of another graining combined glass plate 201 according to the present invention.

[0112] The graining combined glass plate 201 is configured in the same manner as the graining combined glass plate 81 shown in FIGS. 8 and 9, but in this embodiment, it is different in that there are two lighting devices 202 and 204 between the first and second glass sheets. Each lighting device 202 and 204 is the same as those shown in FIGS. 5 and 6, has respective ends 203 and 205, and enables power to be supplied to the light emitting diodes as described above.

[0113] Furthermore, in this embodiment, the first glass sheet 206 has two unclear regions 208 and 210. At the edge of the first unclear region 208, there is a first fade-out band 212, and at the edge of the second unclear region 210, there is a second fade-out band 214. Between the fade-out regions, the graining combined glass plate 201 is optically transparent.

[0114] The unclear regions 208 and 210 and the fade-out regions 212 and 214 are screen printed using a conventional screen printing process. Referring to FIG. 3, the main surface 3b has the unclear regions 208 and 210 and the fade-out regions 212 and 214 printed thereon.

[0115] The first unclear region 208 has an opening 216, and in the opening 216 is the first lighting device 2 ​​​​​​​​​​​​There is a first dot array for diffusing the light emitted from the light-emitting diode of 02. Also, the second unclear region 210 has an opening 218, and in the opening 218 there is a first dot array for diffusing the light emitted from the light-emitting diode of the second illumination device 204.

[0116] The dot arrays in the first and / or second regions 216, 218 can be printed simultaneously with the unclear regions 208, 2 10 and / or the fade-out regions 212, 214, or can be printed by other timing, for example, after the unclear regions 208, 210 and / or the fade-out regions 212 、214 are printed.

[0117] In the previous figures, the combined frosting has been shown as flat (or planar), but providing combined frosting that is curved in at least one direction is within the scope of the present invention. Preferably, the radius of curvature in at least one direction is 500 mm to 20,000 mm and more preferably 1000 mm to 8000 mm.

[0118] In the foregoing examples describing the glass sheet, a glass composition suitable for glass is a soda lime silica glass composition. A typical soda lime silica glass composition is (by weight), Si O2 is 69 - 74%, Al2O3 is 0 - 3%, Na2O is 10 - 16%, K2O is 0 - 5 %, MgO is 0 - 6%, CaO is 5 - 14%, SO3 is 0 - 2%, Fe2O3 is 0.00 5 - 2%. Such glass can be manufactured using the float process.

[0119] Other glass compositions, such as borosilicate glass or alkali aluminosilicate glass, can be used.

[0120] Furthermore, part or all of the glass sheet in the above-described embodiment can be replaced with another type of glazing glass sheet, for example, a plastic sheet such as polycarbonate. It is possible.

[0121] The present invention is particularly advantageous when combined glazing having a lighting function is required. By diffusing the light from the lighting device in a dot array, the point light source property of a light source in a part of the lighting device is reduced, and more uniform illumination is provided. ​
