Title:
LIGHT-EMITTING DIODE REFLECTOR
Document Type and Number:
WIPO Patent Application WO/2022/145730
Kind Code:
A1
Abstract:
A light-emitting diode reflector of the present invention is formed from a thermoplastic resin composition comprising: about 100 parts by weight of a polyester resin including a repeating unit represented by chemical formula 1; about 5-40 parts by weight of a white pigment; about 5-30 parts by weight of glass fiber; about 0.1-3 parts by weight of a pentaerythritol diphosphite compound represented by chemical formula 2; and about 0.1-3 parts by weight of DOPO, wherein the weight ratio of the pentaerythritol diphosphite compound and the DOPO is about 1:0.2-1:5. The light-emitting diode reflector has excellent reflectivity, reflectivity retention rate, thin film formability, impact resistance, heat resistance, and property balances thereof.
