Abstract:
(EN) The present invention relates to an LED lighting apparatus, and to a surface emitting method for the LED lighting apparatus. The LED lighting apparatus of the present invention comprises: LEDs arranged on a substrate; a light guide plate having a bottom surface with grooves for accommodating the LEDs; an upper groove formed at a portion of the light guide plate; and a surface emission assisting member arranged in the upper groove to transmit a portion of the light emitted by the LEDs upward and to diffuse the transmitted light, and to reflect the rest of the light to the substrate. In addition, the surface emitting method for the LED lighting apparatus according to the present invention comprises the steps of: reflecting a portion of light emitted by the LEDs to the lower surface of the light guide plate, and transmitting an amount of light smaller than that of the reflected light; and diffusing the transmitted light over the LEDs to compensate for the difference in the illumination above the LEDs and in the illumination at the periphery of the LEDs caused by the reflection of light emitted by the LEDs. The thus-configured apparatus of the present invention transmits a portion of the light emitted by the LEDs to the center of reflection means for reflecting light emitted by the LEDs, and diffuses a portion of the transmitted light above the LEDs, to thereby achieve a surface emission with a uniform illumination intensity.
(FR) La présente invention concerne un appareil d'éclairage à LED et un procédé d'émission de surface pour l'appareil d'éclairage à LED. L'appareil d'éclairage à LED de la présente invention comprend : des LED agencées sur un substrat ; une plaque de guidage de lumière comportant une surface inférieure avec des rainures pour recevoir les LED ; une rainure supérieure formée dans une partie de la plaque de guidage de lumière ; et un élément d'aide à l'émission de surface agencé dans la rainure supérieure pour transmettre une partie de la lumière émise par les LED vers le haut et pour diffuser la lumière transmise, et pour réfléchir le reste de la lumière vers le substrat. De plus, le procédé d'émission de surface pour l'appareil d'éclairage à LED selon la présente invention comprend les étapes consistant à : réfléchir une partie de la lumière émise par les LED vers la surface inférieure de la plaque de guidage de lumière, et transmettre une quantité de lumière inférieure à celle de la lumière réfléchie ; et diffuser la lumière transmise sur les LED pour compenser la différence d'éclairage au-dessus des LED et d'éclairage à la périphérie des LED provoquée par la réflexion de la lumière émise par les LED. L'appareil ainsi configuré de la présente invention transmet une partie de la lumière émise par les LED vers le centre de moyens de réflexion pour réfléchir la lumière émise par les LED, et diffuse une partie de la lumière transmise au-dessus des LED, pour obtenir de ce fait une émission de surface avec une intensité d'éclairage uniforme.
(KO) 본 발명은 엘이디 조명장치 및 엘이디 조명장치의 면발광방법에 관한 것으로, 본 발명 엘이디 조명장치는 기판에 실장된 엘이디와, 상기 엘이디를 수용하는 수용홈을 저면에 가지는 도광판과, 상기 도광판의 일부에 마련된 상부홈과, 상기 상부홈에 마련되어 상기 엘이디로부터 발원된 광의 일부를 상부측으로 투과시킨 후 그 투과된 광을 확산시키고, 나머지 광은 상기 기판 측으로 반사시키는 면발광보조기재를 포함한다. 또한 본 발명 엘이디 조명장치의 면발광 방법은, 엘이디의 광의 일부를 도광판의 하부측으로 반사시킴과 아울러 그 반사되는 광에 비하여 더 적은 광이 반사되지 않도록 투과시키는 단계와, 상기 투과된 광을 상기 엘이디의 상부측에서 확산시켜, 상기 엘이디의 광의 반사에 따라 엘이디 상부의 조도와 주변부의 조도 차이를 보상하는 단계를 포함한다. 이와 같은 구성의 본 발명은 엘이디의 광을 반사시키는 반사수단의 중앙부에 광의 일부를 투과시키고, 투과된 광의 일부가 엘이디의 상부측에서 확산되도록 하여, 균일한 조도의 면발광을 이룰 수 있다.
