8.1 Introduction HDF Lamp & Lamp House
Xenon Lamp and Lamp House
Xenon lamp s are highly pressurized. At roo m 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 somew here be tween 30 and 50 b ar. Th e bulb temperature of
an ignited lamp is approximately 700°C and the tem perature of the arc is approximately 12000°C! To ignite a xenon lam p a voltage
of 40000 volt is required. Once the lamp is ignited the startup voltage drops to 28 volt. The DC cur rent consum ed by the lamp during
normal operation c an increase to 100 am pere. T he maximum light produced by the xe non lamp inside the HDF projector is rou ghly
90000 lumens.
The xenon lamp is safely sheltered inside the Lamp Hous e. T he Lam p H ouse exist in a reflector, a UV blocker, a lamp anode socket,
a lamp cathod e sock et, a Lamp Info module, and an X YZ-adjustment m echanism to align the lamp in the reflec tor. The Lam p House
can handle xenon lamps up to 4000 Watt. T he xenon lamp and Lamp House can be removed from the projector as a whole, which
allows a fast lamp replacement in cases w hen time is critical.
The Lamp Info m odule holds the lamp parameters and keeps track of the lamp history such as lam
p power, num ber o f strikes, total
lamp run time, etc. For that it is important to reset the lamp parameters after each lam p replacement.
