Abstract:
1. A reflector for a light emitting diode (LED) prepared from a polyester resin composition comprising: (A) about 100 parts by weight of polyester resin with a melting point of about 200° C. or more and including repeat units of the following Formula 1; (B) about 0.1 to about 80 parts by weight of white pigment; and (C) about 0.01 to about 80 parts by weight of filler, wherein the reflector for the light emitting diode has an initial reflectance value of about 90 or more at a wavelength of 440 nm measured using a color-difference meter and a decline of reflectance value of less than about 10 which is measured again after maintaining the reflector for the light emitting diode under conditions of 85° C. and 85% relative humidity for 144 hours:
