Title (EN) LED LENS
(FR) LENTILLE À DIODE ÉLECTROLUMINESCENTE
(KO) 엘이디 렌즈
Abstract:
(EN) The present invention relates to an LED lens capable of uniformly dispersing light emitted from an LED. The LED lens according to one embodiment of the present invention, which is an LED lens for uniformly dispersing light emitted from an LED, comprises: an incident surface through which light emitted from the LED is incident on the inside of the lens; and a light-emitting surface for emitting the light, incident on the inside of the lens through the incident surface, to the outside of the lens, wherein the light-emitting surface comprises: a first light-emitting surface that forms a convex curved shape on the LED side in a vertical cross-section; and a second light-emitting surface that is located around the first light-emitting surface, and forms a convex curved shape on the opposite side of the LED. A convex portion having an upwardly convex shape in the vertical cross-section is formed in a region of an inflection point existing at a portion where the first light-emitting surface and the second light-emitting surface are connected, and the convex portion can be formed in a circular band shape which surrounds the inflection points existing in a circular shape about the optical axis of the LED in a plane.
(FR) La présente invention concerne une lentille à DEL capable de disperser uniformément la lumière émise par une DEL. La lentille à DEL selon un mode de réalisation de la présente invention, qui est une lentille à DEL pour disperser uniformément la lumière émise par une DEL, comprend: une surface incidente à travers laquelle la lumière émise par la diode électroluminescente est incidente sur l'intérieur de la lentille; et une surface d'émission de lumière pour émettre la lumière, incidente sur l'intérieur de la lentille à travers la surface d'incidence, à l'extérieur de la lentille, la surface d'émission de lumière comprend : une première surface d'émission de lumière qui forme une forme incurvée convexe sur le côté de la DEL dans une section transversale verticale; et une seconde surface d'émission de lumière qui est située autour de la première surface d'émission de lumière, et forme une forme incurvée convexe sur le côté opposé de la DEL. Une partie convexe ayant une forme convexe vers le haut dans la section transversale verticale est formée dans une région d'un point d'inflexion existant au niveau d'une partie où la première surface électroluminescente et la seconde surface électroluminescente sont reliées, et la partie convexe peut avoir une forme de bande circulaire qui entoure les points d'inflexion existant selon une forme circulaire autour de l'axe optique de la DEL dans un plan.
(KO) 본 발명은 엘이디에서 나오는 빛을 고르게 확산시킬 수 있는 엘이디 렌즈에 관한 것이다. 본 발명의 일실시 예에 따른 엘이디 렌즈는, 엘이디에서 나오는 빛을 고르게 확산시키기 위한 엘이디 렌즈에 있어서, 상기 엘이디에서 나오는 빛이 상기 렌즈 내부로 입사하는 입사면과, 상기 입사면을 통해 상기 렌즈 내부로 입사한 빛을 상기 렌즈 외부로 출사시키는 출사면을 포함하고, 상기 출사면은 수직단면상 상기 엘이디 측에 볼록한 곡면 형상을 형성하는 제1출사면과, 상기 제1출사면의 주위에 위치하고 상기 엘이디 반대측에 볼록한 곡면 형상을 형성하는 제2출사면을 포함하고, 상기 제1출사면과 상기 제2출사면의 접속부분에 존재하는 변곡점 부위에는 수직단면상 상방으로 볼록한 형상을 가지는 볼록부가 형성되고, 상기 볼록부는 평면상 상기 엘이디의 광축을 중심으로 원형의 형태로 존재하는 변곡점을 감싸는 원형의 띠 형상으로 형성될 수 있다.
