Claims10
A method for manufacturing a solar concentrator, the method comprising:
- providing a mold for press-molding a solar concentrator having a light entry face, a light exit face, a support frame including an outer flange, as well as, arranged between the light entry face and the light exit face and tapering in the direction of the light exit face, a light passage guide portion, which is restricted by a light-passage-guide-portion surface between the light entry face and the light exit face;
- the mold comprising a first mold and at least one second mold;
- and
- press-molding glass between the first mold and the second mold to form the solar concentrator, in terms of the first mold molding the light entry face;
- press-molding a surface of the support frame facing the light exit face by
- means of a first mold part of the second mold and by means of a second mold part of the second mold, wherein the first mold part, at least partially, encloses the second mold part;
- and
- press-molding the light exit face by means of at least a third mold part of the second mold.
