Method for manufacturing a curable, slab-like light-conducting body, mold for carrying out the method and a light-conducting body produced in accordance with the method

A method for manufacturing a curable light-conducting body (21) in a casting method, wherein

• a) in a first method step, a light-conducting mat (1) is fixed at the bottom (28) of a casting mold (27),
• b) in a second method step, the casting mold (27) is filled with a curable casting material (36, 56, 66) until the light-conducting mat (1) is embedded in the curable casting material (36, 56, 66),
• c) in a third method step, filling the casting mold (27) with the curable casting material (36, 56, 66) is continued until there is an overfill (67) of the casting material over the embedded light-conducting mat (1),
• d) and, in a fourth method step, a pressing plate (59) is pressed on the overfill (67) and at least partially displaces the overfill and thereby compacts the casting material (36, 56, 66) (FIG. 15, 16).

A method for manufacturing a curable light-conducting body (21) in a casting method, wherein

• a) in a first method step, a dimensionally stable retaining profile (68) that is complementary to the bottom-side profile of the light-conducting mat (1) is anchored at the bottom (28) of the casting mold (27),
• b) in a second method step, the light-conducting mat (1) is anchored on the retaining profile (68),
• c) in a third method step, the casting mold (27) is filled with a curable casting material (36, 56, 66) until the light-conducting mat (1) in embedded in the curable casting material (36, 56, 66),
• d) in a fourth method step, filling the casting mold (27) with the curable casting material (36, 56, 66) is continued until there is an overfill (67) of the casting material over the embedded light-conducting mat (1),
• e) in a fifth method step, a pressing plate (59) is pressed on the overfill (67) and at least partially displaces the overfill and thereby compacts the casting material (36, 56, 66) (FIG. 18, 19).

A method for manufacturing a curable light-conducting body (21) in a casting method, wherein

• a) in a first method step, a dimensionally stable negative mold (69, 70) having a profile that is complementary to the profile of the light-conducting mat (1), is anchored at the bottom (28) of the casting mold (27),
• b) in a second method step, the casting mold (27) is filled with a curable casting material (36, 56, 66) until the negative mold (69, 70) is embedded in the curable casting material (36, 56, 66),
• c) in a third method step, filling the casting mold (27) with the curable casting material (36, 56, 66) is continued until there is an overfill (67) of the casting material over the embedded negative mold (69, 70),
• d) in a fourth method step, a pressing plate (59) is pressed on the overfill (67) and at least partially displaces the overfill and thereby compacts the casting material (36, 56, 66) (FIG. 18, 19),
• e) in a fifth method step, the cured casting material (36, 56, 66) is removed from the casting mold (27),
• f) in a sixth method step, the negative mold (69, 70) sitting in the cured casting material (36, 56, 66) is removed,
• g) and, in a seventh method step, a light-conducting mat (1) is inserted into the cavities of the cured casting material (36, 56, 66) resulting from the removal of the negative mold (69, 70) (FIG. 19-22).
