A telescopically collapsible image projector has a tri-segmented body. Within the body is mounted a light source, an imaging device such as a fully colour LCD display capable of receiving electronic signals representing images for display, keystone correction means, focusing means, and heat dissipation means. In its operating configuration the body segments are fully extended and a rigid optical pathway is established. Upon full extension, heat sinks in the form of air voids are created to collect radiated heat from operating components of the projector. A forced air system comprising a fan/motor combination draws cooling air in through the body of the projector and exhausts heated air through an exhaust port. In its stowed configuration, the heat sink air voids are used as stowage space to enable the body segments of the projector to telescopically collapse within each other forming a compact object with a small stowage foot print.
