Abstract
A light source device for a video monitor including a concave reflector with a middle opening and an optical axis, said optical axis being positioned tilted obliquely and a discharge lamp including an emission part with a cathode and an anode located opposite to one another and being supported by hermetically sealed portions, one of the hermetically sealed portions being mounted in the middle opening of the concave reflector in a manner that a lengthwise axis of the discharge lamp substantially aligns with the optical axis of the concave reflector, where the anode of the discharge lamp is positioned closer to the rear reflector than the cathode of the discharge lamp, and a tip of the anode is positioned underneath an obliquely tilted plane that includes the lengthwise axis of the discharge lamp.
