摘要： A light source device having a light source and a concave mirror properly arranged optically without requiring a conspicuous device and a production method therefor, an adjusting device for adjusting an optical arrangement in the light source device, and an illuminating device and projection type display device using the light source device. Before mounting an arc lamp, a board (122) having a tungsten lamp (121) fixed thereto is mounted to an ellipsoidal mirror fixing board (103), a base board (104) is moved on and fixed to a bottom board (106) so that a spot diameter of a reflection light from an ellipsoidal mirror (102) is minimal on an ellipsoidal mirror condensing status confirming surface (105) disposed in a position in which a second focal point of the mirror (102) is to be disposed, and the tungsten lamp (121) is removed and the arc lamp is mounted, thereby implementing an optical arrangement-adjusted lamp house. An illuminating device and projection type display device comprise this lamp house.

摘要： The invention concerns an illumination device, particularly for wavelength dependent light outcoupling with at least one, preferably wavelength dependent, mirrored surface (7) within the lamp's beam (1) to separate the beam into a component used for illumination and an unused spectral component. The purpose of the invention is to provide an illumination device and a method to optimise illumination quality using simple means. The basic purpose of the invention is solved by placing a mirror (16) in the beam of the unused spectral component which reflects it in the direction of a mirrored surface and a portion of which is projected on to a viewing screen (19) for adjustment.

摘要： An illumination optical system includes a light source for emitting a plurality of different colors of light, a plurality of rotating optical scanners, and a plurality of scanning lenses. Each of the optical scanners has a reflecting surface that is formed helically around a cylindrical body. The different colors of light enter the respective reflecting surfaces in the direction parallel to the rotation axis, are reflected therefrom, and pass through the scanning lenses, so that each color of light is magnified and then scans the region to be illuminated sequentially. This makes it possible to provide an illumination optical system that can improve scanning linearity, lower noise because of its reduced wind resistance, and achieve reduction in the cost and power consumption.

摘要： A TIR prism system for DMD and a projector adopting the same make a loss of incidence light be reduced, and having a small size and light weight. In a TIR prism system having the DMD and for total reflecting the incidence light to a certain direction in accordance with that the DMD is controlled, the TIR prism system of the present invention includes a first prism for receiving the incidence light on a surface set before, refracting the light, and outputting the refracted light, and a second prism coupled to the first prism for receiving the light outputted from the first prism, transmitting the light to the DMD, and outputting the transmitted light after being totally reflected in accordance with that the DMD is controlled, whereby a loss of light energy inside the system can be reduced.

摘要： Bei einer Projektionseinheit (6) werden zur Darstellung von Informationen auf einer Abbildungsfläche (20) drei Lichtquellen (7, 8, 9) verwendet. Die Lichtquellen (7, 8, 9) strahlen hierzu Licht unterschiedlicher Wellenlänge ab, welches zunächst als jeweils separater Farbkanal (16, 17, 18) in jeweils eine darauf abgestimmte Flüssigkristallanzeige (LCD) (10, 11, 12) fällt. Die Farbkanäle (16, 17, 18) werden anschließend mittels farbselektiver Spiegelflächen (14, 15) eines dichroiden Körpers (13) einander überlagert. Durch einen jeweils auf das Farbspektrum der verschiedenen Lichtquellen (7, 8, 9) abgestimmten Abstand (d', d'', d''') von dem dichroiden Körper (13) wird die Wellenlängenabhängigkeit des Brechungsindexes der Linse (19) ausgeglichen, so dass die Farbkanäle (16, 17, 18) mit einheitlicher Brennweite (d B ) auf der gemeinsame Abbildungsfläche (20) abgebildet werden. Eine aufwendige Korrekturoptik zum Ausgleich der Wellenlängenabhängigkeit der Linse (19) kann somit entfallen.

摘要： To achieve a projection lens which has a wide angle view, a short projection distance and telecentricity and in which the projection can be performed with high contrast, various aberrations such as distortion aberration, etc. are reduced and the optical path is converted. A first lens group having negative refractive power and second and third lens groups having positive refractive power are arranged from a longer conjugate side. Representing a back focus at a projection distance of infinite point by BF; the composite focus distance of the entire system by F; the central air spacing between said first lens group and said second lens group by GD1; the composite focus distance of said first lens group by F1; the composite focus distance of said second lens group and said third lens group by F23; and the central air spacing between said second lens group and said third lens group by GD2, the following equation is satisfied: [2.8 At this time, the focus adjustment is carried out by moving the first lens group along the optical axis OA.
