PURPOSE:To facilitate the attachment of a supporting member to a reflecting plate and a heat collecting member, by forming the supporting leg section of the supporting member approximately in the shape of an arc to be made firmly in contact with a glass pipe inner circumferential surface, and forcibly resiliently pressing the resilient clamping piece sections against upper opposite sides of the heat collecting member. CONSTITUTION:Each support member 4 has a support leg section 4a in the shape of an arc to be made firmly in contact with the inner circumferential surface of a glass pipe 1. The support leg section 4a has an anchoring piece 4b projecting toward the axis of the glass pipe 1 to be inserted and anchored into an anchoring hole 3a formed in the edge of a semi-circular reflecting plate 3 and also has a support piece section 4c projecting toward the axis of the glass tube 1 at the bottom of the glass tube 1 and inserted into a notch 3b formed in the central part of the semi-circular reflecting plate 3. Thus the support piece sections 4c cooperatively support the heat collecting plate 2b. The support leg sections 4a each have a resiliently clamping piece 4d extending from the upper section thereof for resiliently pressing the heat collecting member 2. Support members 4 are arranged along the lengths of the reflecting plate 3 and the heat collecting member 2 at a suitable interval. |
