Abstract
An illumination system for a display apparatus is capable of reducing electric power consumption and lengthening a life span by minimizing a loss of marginal rays that are spaced away from a main optical axis. The minimum loss of the marginal rays is obtained by a light reflective surface of a predetermined degree of curvature formed on an optical device for diffuse-reflecting and altering an optical path of a light from a light source.
Claims14
An illumination system for a display apparatus, comprising:
- a light source emitting light;
- image generator for generating an image using the light emitted from the light source;
- and
- optical unit having a light reflective surface for condensing the light emitted from the light source on the image generator by diffuse-reflecting the light, the light reflective surface of the optical unit having a predetermined degree of curvature.
A system comprising:
- a light source to emit a light;
- an image generator to generate an image by using the light;
- and
- an optical condensor having a curved light reflective surface to condense the light emitted from said light source on said image generator,
- the light condensed on said image generator having a uniform illumination.
A system comprising:
- a light source to emit a light;
- an image generator to generate an image by using the light;
- an optical condenser having a curved light reflective surface to condense the light emitted from said light source on an optical reflector by diffuse-reflecting the light;
- and
- a projected lens,
- the light on the image generator being reflected through said optical reflector and focused by said projected lens on an eye of the user.
A method to generate an image, comprising:
- emitting light;
- and
- condensing the light on an image generator with an optical condenser having a curved surface,
- the light condensed on said image generator having a uniform illumination.
A head mount display comprising:
- a light source to emit a light;
- an image generator to generate an image by using the light;
- and
- an optical condenser having a curved light reflective surface to condense the light emitted from said light source on said image generator by diffuse-reflecting the light.
