Disclosed is a polycarbonate resin composition for LED lighting, in which transmittance and durability are simultaneously improved by using a combination of a benzoxazole compound and a polyorganosiloxane compound in a specific amount in a polycarbonate resin. The present invention provides the polycarbonate resin composition comprising: 97 to 99.9 wt% of the polycarbonate resin; 0.001 to 1.5 wt% of the benzoxazole compound; and 0.001 to 1.5 wt% of the polyorganosiloxane compound. 폴리카보네이트 수지에 벤조옥사졸 화합물과 폴리오가노실록산 화합물을 특정 함량으로 조합 사용함으로써 투과율 및 내구성이 동시에 향상된 LED 조명용 폴리카보네이트 수지 조성물이 개시된다. 본 발명은 폴리카보네이트 수지 97~99.9중량%, 벤조옥사졸 화합물 0.001~1.5중량% 및 폴리오가노실록산 화합물 0.001~1.5중량%를 포함하는 폴리카보네이트 수지 조성물을 제공한다.
