2. SAFETY - SPECIFIC ATTENTION IS REQUIRED FOR UHP LAMPS
UHP lamps are designed and produced as a (spare) part of projection devices, manufactured by
OEM’s worldwide and sold worldwide. This type of discharge lamp contains mercury. In operation,
the UHP lamp gets extremely hot and develops a very high internal pressure. In case of bulb rupture,
the safety of the application is to be secured by adequate shielding of the lamp in order to avoid glass
parts coming out of the device. Furthermore, instructions for both workforces in manufacturing and
the end user/ consumer (user manuals, safety leaflets) should warn for risks and indicate precautions
to be taken to avoid (prolonged) exposure to mercury vapour in case of bulb rupture.
Mercury:
Mercury is a toxic compound.
In case of bulb rupture in non-operative mode, avoid inhalation of mercury vapour, and clean the
spilled mercury according prevailing safety procedures.
In case of bulb rupture during lamp operation, mercury vapour will be emitted. Avoid inhalation take
precautions to avoid prolonged exposure to this mercury vapour.
Furthermore, user manuals and instructions for the end user (consumer) should indicate precautions
to be taken to avoid prolonged exposure to mercury vapour in case of bulb rupture.
High Operating Lamp Temperature
In operation the lamp gets extremely hot, as well as surrounding parts in the projection device.
Before touching lamp, driver and/or other internal parts make sure the projection device has
sufficiently cooled down.
High Intensity Light Beam:
When operating the lamp creates a very high intensity beam, never look directly in an operating lamp.
UV radiation:
The lamp generates some amount of UV radiation, never look directly into an operating lamp.
High Voltage:
Safety protection is needed for the lamp area because of the high ignition pulses (ranging from 5 kV to
max. 25kV, dependent on lamp type)
For extensive information regarding Product / Material Safety, please refer to the
Product Safety Data Sheet (PSDS) for UHP lamps ( www.philips.com/dpl )
3. INSTRUCTION FOR USE
UHP lamps tend to wear out over lifetime and the probability of bulb rupture progressively increases
beyond the specified lifetime, In order to minimise risk of bulb rupture, do not operate the lamp (or
do not allow operation) beyond the specified life time.
To replace the lamp, the power should always be switched off. See also user instructions of the set
manufacturer for lamp replacement.
Never touch the front glass with bare hands. If bare hands have touched it, the front glass should be
cleaned with a lint free towel before installing the lamp.
The lamp should be operated on the lamp driver as mentioned in page 1.
The lamp area should be protected against high ignition pulses (max 25kV).
