Abstract

A projector which projects an image, includes: an optical configuration section which includes: a light source which emits light; an optical conversion section which includes a conversion section which converts the light emitted from the light source into an image based on image data; and a projection lens which enlarges and projects the image converted by the optical conversion section; a circuit configuration section which operates the optical configuration section; a housing which is included in the exterior of the projector and includes, in its outer surface portion, a heat releasing section; and a heat transfer member which transfers, to the housing, heat emitted by heat emitting components of the circuit configuration section and the optical configuration section.

Claims (19)

1. A projector which projects an image, comprising:

an optical configuration section which includes:

a light source which emits light;

an optical conversion section which includes a conversion section which converts the light emitted from the light source into an image based on image data; and

a projection lens which enlarges and projects the image converted by the optical conversion section;

a circuit configuration section which operates the optical configuration section;

a housing which is included in the exterior of the projector and includes, in its outer surface portion, a heat releasing section; and

a heat transfer member which transfers, to the housing, heat emitted by heat emitting components of the circuit configuration section and the optical configuration section,

a cooling spatial region which is apart from a body interior spatial region, in which heat source parts of the light source and the circuit configuration section are disposed, and

a cooling fan which expels air to the heat releasing section, the cooling fan being disposed in the cooling spatial region.

2. A projector according to claim 1 , further comprising:

a cover member which, covering the heat releasing section and being attached to the housing, allows air expelled from the cooling fan to flow,

the cooling fan being set up in a vicinity of the heart releasing section.

3. A projector according to claim 2 , the cooling spatial region being formed by the housing and the cover member, and the body interior spatial region in an interior of the projector and the optical configuration section, being separate from one another.

4. A projector according to claim 2 , the cover member being configured of a member having heat conductivity.

5. A projector according to claim 1 the heat releasing section is being formed with fins.

6. A projector according to claim 5 , the fins being formed at least in the upper surface or side surface of the projector.

7. A projector according to claim 5 the cooling fan being positioned level with the fins.

8. A projector according to claim 5 , the fins having a spatial region formed radiating outward relative to the cooling fan.
