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.
