Image projection apparatus

摘要

An image projection apparatus includes a light source, light from which is used to form an image to be projected, a first flow path, a control unit configured to control a light emission from the light source, an electrical power stabilizing unit configured to stabilize an electrical power to be supplied to the light source, and an electrical power source unit configured to supply the electrical power to at least one of the control unit and the electrical power stabilizing unit. One or both of the electrical power source unit and the electrical power stabilizing unit is/are divided into a plurality of boards. The light source is arranged on a normal line of a surface of any of the plurality of boards. The plurality of boards configure surfaces of the first flow path except a surface nearest to the light source.

主权项

1. An image projector, comprising:
a light source to emit light; a fan to make air flow from an air inlet of the image projector toward an exhaust outlet of the image projector; and circuit boards which are internal to the image projector, wherein the circuit boards are disposed to guide the air flow from the air inlet to the exhaust outlet, the image projector further comprising: an image generator to generate an image using the light source; a concave mirror to reflect the image from the image generator to project the image; and a case to accommodate the light source, the concave mirror, and the circuit boards, wherein: a flow path is defined by at least a back surface of the concave mirror and a surface of the case opposite to the back surface of the concave mirror, and the air flowing toward the exhaust outlet is supplied from the flow path.
