Abstract

The invention relates to an image projection device and a light source assembly with a light source and a cover component which are integrally formed. The image projection device and the light source assembly aim to suppress high temperature of the cover component caused by high temperature of the light source in the light source assembly with the light source and the cover component which are integrally formed. The image projection device is provided with the light source assembly (50) which can be detached on the device body through a light source assembly taking-out opening (18a) of the device body. A discharging lamp (51) in the light source assembly is used for transmitting a light projection image. A light source assembly cover (52) of the light source assembly taking-out opening is integrally formed with the light source in a state that relative displacement relative to the light source can be performed. In a mounting state that the light source assembly is mounted on the device body, a direct connecting part or indirect connecting part between the light source and the cover component is restricted to a direct connecting part or indirect connecting part when relative displacement between the light source and the cover component occurs in a non-mounting state in which the light source assembly is not mounted on the device body.

Description

technical field [0001] The present invention relates to an image projection device and a light source assembly. Background technique [0002] The existing image projection apparatus projects a projection image obtained by irradiating an image generating element with light emitted by a light source in a light source assembly onto a projection surface. The light source assembly of the image projection apparatus can be attached to and detached from the apparatus main body. [0003] Patent Document 1 (JP Patent No. 453143 ) discloses an image projection apparatus in which a light source assembly is detachable from the apparatus main body of the image projection apparatus, and the light source assembly can be replaced when the light source in the light source assembly reaches the end of its life. In this image projection device, the light source assembly can be exchanged through the top opening by removing the lamp cover (cover member) for closing the top opening (attachment and...
