ABSTRACT:
Disclosed is an anti-UV reflector for distributing a light from a point light source or a linear light uniformly over a target. The anti-UV reflector mainly includes a light reflecting polymeric substrate and a protecting layer of anti-UV material provided on the polycarbonate substrate for reducing yellowing in the polycarbonate substrate. When a light from a point light source or a linear light illuminates the anti-UV reflector, UV radiation in the light is filtered or absorbed by the protecting layer thereby reducing yellowing in the polyearbonate substrate.
