Introduction HDF Lamp & Lamp House
Xenon Lamp and Lamp House
Xenon lamps are highly pressurized. At room temperature the pressure inside the bulb is between 10 and 15 bar. When ignited, the
normal operating temperature of the bulb increases the pressure up to somewhere between 30 and 50 bar. The bulb temperature of
an ignited lamp is approximately 700°C and the temperature of the arc is approximately 12000°C! To ignite a xenon lamp a voltage
of 40000 volt is required. Once the lamp is ignited the startup voltage drops to 28 volt. The DC current consumed by the lamp during
normal operation can increase to 100 ampere. The maximum light produced by the xenon lamp inside the HDF projector is roughly
90000 lumens.
The xenon lamp is safely sheltered inside the Lamp House. The Lamp House exist in a re
fl
ector, a UV blocker, a lamp anode socket,
a lamp cathode socket, a Lamp Info module, and an XYZ-adjustment mechanism to align the lamp in the re
fl
ector. The Lamp House
can handle xenon lamps up to 4000 Watt. The xenon lamp and Lamp House can be removed from the projector as a whole, which
allows a fast lamp replacement in cases when time is critical.
The Lamp Info module holds the lamp parameters and keeps track of the lamp history such as lamp power, number of strikes, total
lamp run time, etc. For that it is important to reset the lamp parameters after each lamp replacement.
