Light source device to be utilized mainly for projection purposes

In an elongated light source device to be used mainly for projection purposes of the type comprising a plurality of series connected tubular light source units each containing a single light emitting element, and a plurality of non-light-emitting sections connected between alternate light source units of said series connected light source units, the improvement wherein said non-light-emitting sections each comprise an elongated rigid metal conductor supporting member connected at each end to a different light source unit, the longitudinal dimension of each of said non-light-emitting sections being substantially aligned with the axes of said light source units connected thereto, said non-light-emitting supporting members being fixed to said tubular light source units in such a way that a lead-in wire extends from the end sealing portion of each of said tubular light source units and is bent to form a mounting loop through which a screw for fixing said supporting member extends, said loop having a dimension in the axial direction of said light emitting elements that exceeds the diameter of said screw, whereby said supporting member is slidably movable toward the longitudinal direction of the adjacent tubular light source unit.
