Filed: 2007-05-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a projector constituted to lower starting voltage applied to a discharge lamp by surely improving starting characteristic of the discharge lamp.  <P>SOLUTION: An LED (light emitting element) 3 is arranged on an optical path through which light from the discharge lamp 2 passes.

An electron is radiated from the surface of an electrode in the light emitting tube 21 by a photoelectric effect by the incident light, thereby easily causing discharge. By applying the starting voltage while making the light incident, the discharge is easily caused to improve the starting characteristic of the discharge lamp 2. Accordingly, the projector has constitution where the applied voltage is made lower than that of the conventional one. By moving the LED 3 to the outside of the optical path simultaneously with lighting the discharge lamp 2, the LED 3 is prevented from being damaged.  <P>COPYRIGHT: (C)2009,JPO&INPIT
