Embodiment Construction

[0029] Embodiments of the present invention will be described with reference to the drawings.

[0030] An embodiment in which the present invention is applied to a DLP (registered trademark) system data projector device will be described below with reference to the drawings.

[0031] figure 1 It is a diagram showing a schematic functional configuration of the data projector device 10 according to the present embodiment.

[0032] The input unit 11 includes, for example, a pin jack (RCA) type video input terminal, a D-sub15 type RGB input terminal, and the like. The analog image signals of various standards input to the input unit 11 are digitized by the input unit 11 and sent to the image conversion unit 12 via the system bus SB.

[0033] The image conversion unit 12 is also called a scaler, and unifies the input image data into image data in a predetermined format suitable for projection, and sends the image data to the projection processing unit 13 .

[0034] At this time,...

Abstract

A projection apparatus includes a fluorescence plate including a fluorescence layer configured to emit fluorescence light beams upon irradiation of the excitation lights, a first lens array, provided on a light source side of the fluorescence plate and including a plurality of lenses arranged in an array to correspond with the light-emitting elements, and configured to collect the fluorescence light beams and emit the fluorescence light beams to be parallel with one another, and a projection unit configured to form an optical image using the fluorescence light beams obtained via the first lens array and project the optical image on a projection object.

Description

[0001] Cross References to Related Applications [0002] According to 35USC119, this application is based on the application dated March 28, 2011, and the application number is JP Japanese Patent Application No. 2011-070897, and claims its priority, including the description, claims, drawings and abstract. The entire content of the author is incorporated herein by reference. technical field [0003] The present invention relates to a projection device suitable for a DLP (Digital Light Processing) (registered trademark) type projector device using a semiconductor light emitting element. Background technique [0004] Conventionally, a technique such as JP-A-2010-164846 has been proposed, in which a phosphor wheel on which a plurality of sector-shaped phosphors are arranged and its rotational drive unit are swung by a motor and a crank mechanism, and the positions of the phosphors irradiated with light beams are cycled. Even if the output of the excitation source of the light ...
