Title (EN) ILLUMINATION UNIT
(FR) UNITÉ D'ÉCLAIRAGE
(JA) 照明ユニット
Abstract:
(EN) Provided is a small-sized illumination unit suitable for providing illumination such as, by turning on or off specific light sources, not illuminating a certain area, or forming a character or shape. An illumination unit comprises a plurality of light sources and an optical system for modulating output light from the light sources. The optical system includes a lens unit comprising a plurality of lenses, and a light-distribution control multiplexing element disposed between the light sources and the lens unit. The light-distribution control multiplexing element is provided with: a plurality of light guide portions which have a tapered shape expanding from the light source side toward the lens unit side, and which guide the output light that has been output from the light sources; and a flat plate portion disposed on the output side of the light guide portions. With respect to the area of an input surface of the light guide portions into which the output light from the light sources is input, the area of an output surface for outputting the light input to the light guide portions toward the flat plate portion is set to be greater by a factor of not less than 1.2 and not more than 2.5.
(FR) L'invention concerne une unité d'éclairage de petite taille appropriée pour fournir un éclairage tel que, en allumant ou en éteignant des sources de lumière spécifiques, une certaine zone ne soit pas éclairée, ou un caractère ou une forme soit obtenu(e). Une unité d'éclairage comprend une pluralité de sources de lumière et un système optique destiné à moduler la lumière de sortie issue des sources de lumière. Le système optique comprend une unité de lentilles comprenant une pluralité de lentilles, et un élément de multiplexage de commande de distribution de lumière disposé entre les sources de lumière et l'unité de lentilles. L'élément de multiplexage de commande de distribution de lumière comporte : une pluralité de parties de guidage de lumière qui ont une forme effilée allant en s'élargissant du côté source de lumière vers le côté unité de lentilles, et qui guident la lumière de sortie qui a été émise par les sources de lumière ; et une partie plaque plate disposée du côté sortie des parties de guidage de lumière. Par rapport à la surface d'une surface d'entrée des parties de guidage de lumière que pénètre la lumière de sortie issue des sources de lumière, la surface d'une surface de sortie permettant la sortie de la lumière ayant pénétré les parties de guidage de lumière vers la partie de plaque plate est définie de façon à avoir une dimension plus grande d'un facteur supérieur ou égal à 1,2 et inférieur ou égal à 2,5.
(JA) 特定の光源を点灯、消灯することによって、ある領域を照らさない、あるいは文字や形を形成するといった照明を行うのに適した小型な照明ユニットを提供する。複数の光源と、前記光源からの出射光を変調する光学系と、を有する照明ユニットは、前記光学系は、複数のレンズからなるレンズユニットと、前記光源と前記レンズユニットとの間に配置された配光制御合波素子とを有し、前記配光制御合波素子は、前記光源側から前記レンズユニット側へ向かうにつれて広がるテーパー形状を有し前記光源から出射された出射光を導光する複数の導光部と、前記導光部の出射側に配置された平板部とを備え、前記導光部における前記光源からの出射光を入射する入射面の面積に対し、前記導光部に入射した光を前記平板部に対して出射する出射面の面積は1.2倍以上、2.5倍以下に設定されている。
