The present invention relates to a quantum dot film for a lighting device, and a lighting device using same. More specifically, the quantum dot film for a lighting device, of the present invention, comprises a resin, and quantum dots which are dispersed in the resin and which has a maximum light-emitting wavelength of 620 nm to 640 nm and a quantum efficiency (Qy) of 90% or more. The quantum dots included in the quantum dot film for a lighting device, of the present invention, have a maximum light-emitting wavelength of 620 nm to 640 nm and have a high quantum efficiency of 90% or more, and thus can effectively convert blue light into red light, and are applied to a lighting device for emitting blue light, and thus can improve optical characteristics so as to satisfy light efficiency and color rendering simultaneously. La présente invention concerne un film à points quantiques pour un dispositif d'éclairage, et un dispositif d'éclairage l'utilisant. Plus spécifiquement, le film à points quantiques pour un dispositif d'éclairage, de la présente invention, comprend une résine, et des points quantiques qui sont dispersés dans la résine et qui présente une longueur d'onde d'émission de lumière maximale de 620 nm à 640 nm et un rendement quantique (Qy) de 90 % ou plus. Les points quantiques inclus dans le film à points quantiques pour un dispositif d'éclairage, de la présente invention, présentent une longueur d'onde électroluminescente maximale de 620 nm à 640 nm et présentent un rendement quantique élevé de 90 % ou plus, et peuvent ainsi convertir efficacement la lumière bleue en lumière rouge, et sont appliqués à un dispositif d'éclairage pour émettre une lumière bleue, et peuvent ainsi améliorer les caractéristiques optiques de façon à satisfaire simultanément l'efficacité lumineuse et le rendu de couleur. 본 발명은 조명 장치용 양자점 필름 및 이를 이용한 조명 장치에 관한 것으로서, 보다 상세하게 본 발명의 조명 장치용 양자점 필름은 수지 및 수지에 분산되며, 최대 발광 파장이 620nm 내지 640nm이고, 양자효율(Qy)이 90% 이상인 양자점을 포함한다. 본 발명의 조명 장치용 양자점 필름에 포함된 양자점은 최대 발광 파장이 620nm 내지 640nm이고 양자효율이 90% 이상으로 높아 청색 광을 적색 광으로 효과적으로 변환할 수 있으며, 이에 청색 광을 발광하는 조명 장치에 적용되어 광 효율과 연색성을 동시에 만족하도록 광학적 특성을 개선시킬 수 있다.
