Abstract

The present invention provides a two-dimensional image forming apparatus (10), comprising a light source (1), two-dimensional image forming units (5a) to (5c) for forming a two-dimensional image from light emitted from the light source, and The magnifying projection unit (6) for enlarging and projecting the two-dimensional image formed by the forming unit, wherein it is provided with a rotating mechanism (11) for rotating the light source (1) to change its light emitting direction, and the rotating mechanism changes the light emitting direction of the light source, so that Emitted light from the light source is taken out as illumination light. In this way, a two-dimensional image forming apparatus that also serves as an illumination device can be realized at low cost, and the range of use of the two-dimensional image forming apparatus can be greatly expanded.

Description

technical field

[0001] The present invention relates to a two-dimensional image forming device, and more particularly, to a two-dimensional image forming device capable of emitting light from a light source for purposes other than projection of a two-dimensional image. Background technique

[0002] Two-dimensional image forming devices typified by liquid crystal projectors are being researched, developed and commercialized because they are easy to display large-screen images such as rear-projection or magnified projection, and their applications are becoming more and more extensive.

[0003] The focus of current research and development on such two-dimensional image forming devices is on the method of miniaturization, high brightness, high illuminance, high contrast, and high resolution performance of the device. Furthermore, as a result of such research and development, for example, a very compact high-brightness device of 1000 ANSI lumens is being put to practical use in a...

Examples

Embodiment Construction

[0075] Hereinafter, embodiments of the present invention will be described using the drawings.

[0076] (Embodiment 1)

[0077] The present invention proposes that on the basis of the two-dimensional image display function of the two-dimensional image forming device, a new function other than image display is added to the device in a simple way by utilizing the inherent characteristics of the two-dimensional image forming device. The structure of the functional two-dimensional image forming device, and its practicability was verified.

[0078] First, in Embodiment 1, it will be described that, in addition to displaying a two-dimensional image, it is possible to display a two-dimensional image by including an optical path switching unit for switching the emission direction of light emitted from a light source in a two-dimensional image forming apparatus. Used as a form of illumination light.

[0079] FIG. 1 shows an example of the structure of a two-dimensional image device a...
