METHOD FOR PROVIDING A HIGH-PRESSURE DISCHARGE LAMP, METHOD FOR PROVIDING LIGHT BY MEANS OF A HIGH-PRESSURE DISCHARGE LAMP AND DIGITAL VIDEO PROJECTOR

摘要

In order to obtain a particularly high maximum light density of a high pressure discharge lamp (10) in a space, without the lamp being heated too much, the parameters of the lamp are specifically determined in accordance with the construction thereof to adapt to a desired power and a maximum current strengthI max defined for the desired power. In formula (I), R? represents the curvature radius (in mm) of the tip of the cathode, e0 represents the distance between electrodes in mm, and P represents the room temperature filling pressure of the xenon gas (in bar) in the high-pressure discharge lamp (10). Higher maximum light densities are obtained, and c is higher.
