Abstract
The illumination apparatus comprises a light source unit which has a LED for emitting illumination light, and a condenser lens for collecting the illumination light, and a main body of the illuminator of the apparatus which holds the light source unit and guides the illumination light. The light source unit comprises a heat dissipation plate which holds LED, and emits the heat emitted from LED 11; and a lens frame which holds the collector lens and the heat dissipation plate so that the relative position of LED to the collector lens may be changed. The main body of the illuminator has a connection hole for connecting communicatively the inside of the main body of the apparatus to the outside, and holds the light source unit by inserting the lens frame into the connected hole.
Claims8
An illumination apparatus comprising:
- a light source unit which includes a semiconductor light emitting element for emitting illumination light and a collector lens for collecting the illuminating light;
- and
- a main body of the apparatus which holds the light source unit and guides the illumination light;
- wherein the light source unit comprises:
- a heat dissipation component which holds the semiconductor light emitting element and dissipates heat emitted from the semiconductor light emitting element;
- and
- a lens frame which holds the collector lens and holds the heat dissipation component in such a manner that a relative position of the semiconductor light emitting element with respect to the collector lens is changeable in a plane perpendicular to an optical axis of the collector lens;
- and
- wherein the main body of the apparatus has a connection hole that communicatively connects an inside of the main body of the apparatus to an outside, to hold the light source unit by inserting the lens frame into the connection hole to fit the lens frame into the connection hole.
