description An illumination device (1) comprising: a light emitting module (30) which has a light emitting element (31a) and a wavelength conversion part (31b) converting the wavelength of light emitted by the light emitting element (31a); a luminance uniformizing plate (50) which is disposed on a light output side of the light emitting module (30); and a diffusing plate (60) disposed on the opposite side of luminance uniformizing plate (50) from the light emitting module (30) side thereof. Furthermore, the distance (H1) between the light emitting module (30) and the luminance uniformizing plate (50) is at least 1/2 of the distance (H2) between the light-emitting module (30) and the diffusing plate (60). L'invention concerne un dispositif d'éclairage (1) comprenant : un module d'émission de lumière (30) qui comporte un élément électroluminescent (31a) et une partie de conversion de longueur d'onde (31b) convertissant la longueur d'onde de la lumière émise par l'élément électroluminescent (31a) ; une plaque d'uniformisation de luminance (50) qui est disposée d'un côté sortie de lumière du module d'émission de lumière (30) ; et une plaque de diffusion (60) disposée du côté de la plaque d'uniformisation de luminance (50) opposé au côté module d'émission de lumière (30) de celle-ci. En outre, la distance (H1) entre le module d'émission de lumière (30) et la plaque d'uniformisation de luminance (50) est d'au moins 1/2 de la distance (H2) entre le module d'émission de lumière (30) et la plaque de diffusion (60). 照明装置(1)は、発光素子(31a)と、発光素子(31a)が発する光を波長変換する波長変換部(31b)とを有する発光モジュール(30)と、発光モジュール(30)の光出射側に配置された輝度均一板(50)と、輝度均一板(50)の発光モジュール(30)側とは反対側に配置され、輝度均一板(50)を通過した光を拡散透過させる拡散板(60)とを備える。そして、発光モジュール(30)と輝度均一板(50)との距離(H1)は、発光モジュール(30)と拡散板(60)との距離(H2)の1/2以上である。
