Title (EN) LIGHT EMITTING DEVICE AND BULB-TYPE LED LAMP
(FR) DISPOSITIF ÉMETTEUR DE LUMIÈRE ET LAMPE À DIODE ÉLECTROLUMINESCENTE DE TYPE AMPOULE
(JA) 発光装置および電球型LEDランプ
Abstract:
(EN) Provided is a light emitting device which can uniformly diffuse and radiate light from all the regions of the globe of an LED bulb without deteriorating light transmission efficiency. A light emitting device (1) is provided with a light scattering/guiding globe (10) and an LED (11) which is disposed on one end of the light scattering/guiding globe (10). The light scattering/guiding globe (10) is a body with no air released from the inside and is composed of a light scattering/guiding material having light scattering particles contained therein. The globe has the bottom surface on the side of the LED (11), and is provided with a first light incoming surface (20) as a first hollow section, which is formed in a circular cone shape in the light outputting direction from the bottom surface.
(FR) L'invention porte sur un dispositif émetteur de lumière qui peut diffuser et rayonner uniformément une lumière à partir de toutes les régions du globe d'une ampoule à diode électroluminescente sans détériorer le rendement de transmission de la lumière. Un dispositif émetteur de lumière (1) comporte un globe de dispersion/guidage de lumière (10) et une diode électroluminescente (11) qui est disposée sur une extrémité du globe de dispersion/guidage de lumière (10). Le globe de dispersion/guidage de lumière (10) est un corps sans air libéré à partir de l'intérieur, et est constitué d'un matériau de dispersion/guidage de lumière comprenant des particules de dispersion de lumière contenues à l'intérieur de celui-ci. Le globe a la surface inférieure sur le côté de la diode électroluminescente (11), et comporte une première surface d'entrée de lumière (20) comme première section creuse, celle-ci étant formée sous la forme d'un cône circulaire dans la direction de sortie de la lumière à partir de la surface inférieure.
(JA)  光透過効率を低下させず、LED電球のグローブ全域で均一に光拡散放射を可能にすること。 光散乱導光体グローブ10と、光散乱導光体グローブ10の一端に設置されるLED11と、を備える発光装置1において、光散乱導光体グローブ10を、光散乱粒子が含有された光散乱導光体からなる充実物体とし、かつLED11側に底面を有し、その底面から光の出射方向に向かう円錐形状の第1の空洞部としての第1の入射面20を備えるものとする。
