ABSTRACT:
A cold cathode fluorescent tube reflector comprises an extruded ABS thermoplastic support subtending an arc of about 317 degrees and dimensioned to snap fit to the tubular body of fluorescent glass tube. The support has bonded thereto a metallized Mylar film which comprises vapor deposited aluminum which forms a specular second surface mirror. The aluminum coating is next to the support and protected from the ambient atmosphere by the clear Mylar film. The reflector is preferably for 7/8 inch diameter tubes and has a film thickness of about 0.8 mils. In one embodiment, the metallized film is attached during extruding of the support. In the alternative, the film is secured to the support during injection molding of the support.
