  • the projection device includes the above-mentioned light source device, a display element that is irradiated with the light source light from the light source device to form an image light, and a projection that projects the image light emitted from the display element onto a screen. It is characterized by having an optical system, the display element, and a projection device control unit that controls the light source device.
  • control unit 38 controls a light source control circuit 41 as a light source control unit, and the light source control circuit 41 so that light in a predetermined wavelength band required at the time of image generation is emitted from the light source device 60.
  • the light emission of the red light source device, the green light source device, and the blue light source device of the light source device 60 is individually controlled.
  • the diffusion transmission region 103a is formed as a region in which blue wavelength band light from the excitation light irradiation device 700, which is laser light, is incident, and the laser light is diffused and transmitted.
  • the diffusion transmission region 103a is formed by a diffusion plate formed in the shape of an arc plate.
  • the transmission region 103b is formed as a region for transmitting the red wavelength band light from the red light source device 120 without diffusing it.
  • the transmission region 103b is formed by a glass plate formed in the shape of an arc plate.

Abstract

Le problème décrit par la présente invention est de fournir un petit dispositif de source de lumière et un dispositif de projection. La solution selon l'invention porte sur un dispositif de source de lumière 60 qui comprend : une diode laser bleue 71 située dans un dispositif d'irradiation de lumière d'excitation 700 et servant à émettre une lumière à première bande de longueur d'onde ; une source de lumière rouge 121 située dans un dispositif de source de lumière rouge 120 et servant à émettre une lumière à seconde bande de longueur d'onde ; une roue fluorescente 101 dans laquelle une région de conversion de longueur d'onde 102 et une région de transmission de lumière 103 sont disposées côte à côte de manière circonférentielle, la région de conversion de longueur d'onde 102 étant une région destinée à convertir la lumière à première bande de longueur d'onde incidente à partir d'une surface en une lumière à troisième bande de longueur d'onde ayant une bande de longueur d'onde différente de la lumière à première bande de longueur d'onde et de la lumière à seconde bande de longueur d'onde et à émettre la lumière à troisième bande de longueur d'onde à partir de l'autre surface, et la région de transmission de lumière 103 est une région destinée à émettre la lumière à première bande de longueur d'onde incidente à partir d'une surface à partir de l'autre surface ; et un miroir dichroïque 146 qui transmet une lumière parmi les lumières à première et à seconde bande de longueur d'onde et qui réfléchit l'autre.
