Abstract

A projector is provided. The projector includes a projection unit which projects an image, a case which supports the projection unit, a reflecting mirror which includes a reflecting surface which faces the projection unit and has a curvature, and reflects light, a first fixing part which is disposed on a center axis of the reflecting mirror on an outer area of the reflecting surface, and a second fixing part and a third fixing part which are disposed on the outer area of the reflecting surface and which form a triangle with the first fixing part. Each of the first, second, and third fixing parts is configured to fix the reflecting mirror to the case.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2011-0086044 filed with the Korean Intellectual Property Office on Aug. 26, 2011, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] Methods and apparatus consistent with the exemplary embodiments relate to a projector, and more particularly, to a projector capable of preventing damage to a projector disposed in the projector due to an increase in internal temperature of the projector. Thermal deformation of the mirror. Background technique [0003] A projector or projection system is a display device that projects an input video signal on a screen using light emitted from a light source such as a light emitting diode (LED) or a lamp, thereby displaying an image. Such display devices may be used to provide presentations in conference rooms or to implement projectors in theaters or home theaters at home. [0004] Prior art projectors project images...
