Abstract: front page image
(EN)Provided are a lighting device and a display device, in which the sizes of the devices can be reduced, the rate of light utilization can be improved, and the generation of interference patterns can be reduced. The lighting device comprises: a light source unit including a laser light source; an optical element which is placed on a light path along which laser light emitted by the laser light source propagates; an optical member which emits illuminating light; and a driving unit which alters the relative positioning between the optical element and the optical member to alter at least one of the position which the laser light enters and the angle at which the laser light enters in an incidence plane of the optical member.
(FR)La présente invention permet de réduire la taille d'un dispositif d'éclairage et d'un dispositif d'affichage, d'améliorer leur taux d'utilisation de la lumière et de réduire l'apparition de motifs d'interférence dans ces dispositifs. Le dispositif d'éclairage comprend : une unité de source de lumière comportant une source de lumière laser ; un élément optique situé sur un trajet de la lumière le long duquel se diffuse la lumière laser émise par la source de lumière laser ; un élément optique qui émet une lumière d'éclairage ; et une unité de pilotage qui modifie le positionnement relatif entre les deux éléments optiques de façon à modifier la position et/ou l'angle d'entrée de la lumière laser dans un plan d'incidence de l'élément optique.
(JA) 小型化および光の利用率向上を図りつつ、干渉パターンの発生を低減することが可能な照明装置および表示装置を提供する。照明装置は、レーザ光源を含む光源部と、レーザ光源からのレーザ光が進行する光路上に配設された光学素子と、照明光を出射する光学部材と、光学素子と光学部材との間の相対位置を変位させることにより、光学部材の入射面内において、レーザ光の入射位置および入射角度のうちの少なくとも一方を変化させる駆動部とを備えている。
