The reflector (2) has a polymer-based structure with a reflective coating applied in one or more layers up to 10 - 50 nm thick, and is reinforced with mineral fibres, especially of glass. The polymer base has a surface roughness of at least 0.1 - 0.2 mcm, and the reinforcing fibres are in strands or twists preferably 4 - 10 mm in length, with the individual strands preferably 15 - 30 mcm in diameter. The base can also contain a filler of talc or mica flakes or carbonate granules. The reflector has mechanical fixings, especially for a lamp holder or mask, and is made by injection moulding. |
