<p>An arc lamp suitable for use as a high intensity light source in a projection system is described. A reflector (44) is arranged to reflect the light produced by the arc into a directional light beam, secondary reflection means being arranged to direct part of the reflected beam so as to compensate for regions which are obscured by the electrodes. Means are provided within the light source to dissipate heat generated by the electrodes.</p> |
