Technical Guide
The diagram shows an example of an OSRAM DULUX
The I
limiting cases.
1. The discharge current of the lamp is fed only via one lead wire
2. The discharge current of the lamp is fed equally via the two lead wires
The intersection of the curve with the line I
gives the value of the minimum discharge current below which heating must be
provided.
The optimum dimming operation would be along the target line. If there are any devia-
tions toward smaller values for I
reduced. If I
the ends of the lamp. Proper lamp operation cannot take place below the „Minimum“
line or above the „Maximum“ line. Only burning duration tests can give a reliable indi-
cation of achievable lamp life in dimmer mode. These tests must be performed by the
control gear manufacturers. Control gear manufacturers are also responsible for carry-
ing out tests on the permissible ambient temperature ranges and on stability in dim-
mer mode.
For optimum operation, new lamps should be burnt in for 100 hours at full output
before they are dimmed for the first time.
