PURPOSE: A multifunctional projection exit light is provided to display various pictograms with one exit light by displaying the pictograms implemented by a projection, and to transmit spot images to a central control chamber in case of urgent emergency through bidirectional communications, and to guide an escape in a right direction according to the spot condition by changing the pictogram of the exit light in a remote place. CONSTITUTION: A projection exit light includes a light source(212), a pictogram board(213), an optical mechanism(216), and a screen(220). The pictogram board is separated from the light source, and generates a pictogram by selectively transmitting light. The optical mechanism processes the pictogram to be formed on the screen. The screen displays the pictogram which passes through the optical mechanism.
