Lamp base to power coupler
contact
Faulty wiring
Good contact between the lamp base and the power coupler is
essential. The lamp is attached to the fixture by the power coupler
only, check to see if the lamp is mounted on the power coupler
correctly.
Check all 5 connections (ground, mains input, HF-output) on the
generator for correct wiring, loose contacts, poor connections, or
broken wiring.
All generators must always be grounded. Generators and
components may be grounded to the fixture or otherwise connected
to the ground. It is hazardous and possibly fatal for a human to make
contact with an ungrounded fixture, generator or other electrical
component while it is in operation.
Coaxial cable
The coaxial cable of the power coupler may not be crushed, i.e. the
bending diameter is limited.
The distance between the (coaxial) generator output cable and the
generator input leads (mains cable) should be as big as possible, but
at least 10cm (~4 inch).
The wire and plug-in connectors between the power coupler and
generator must not be altered in any way and must be kept away
from the surface of the lamp.
Power coupler cooling
QL lamps are restricted to an optimum operating temperature. For
example, lamp and power coupler should be firmly attached on a
heat sink with 4 bolts with a prescribed diameter, length and
material. Otherwise, the lamp may produce low light output or fail
early.
The generator and power coupler are not mounted on a shared heat
sink.
Generator cooling
Lamp damage due to handling or
shipping
The bottom of the generator is mounted flat against a large metallic
surface of the fixture for good heat transfer.
The generator and power coupler are not mounted on a shared heat
sink.
Damage to the system from handling or shipping may cause a crack
in the glass or broken wires.
