  • the data are divided into groups: a) lamp-type-specific reference data REF-S1, b) first, lamp-type-specific information INF1, c) second information INF2, d) third information, which designate different operating modes for each lamp type, and e) control sequence data SEQ, which in general form are specified, and in brackets voltage values U or current values I, the corresponding voltages or currents being supplied to the lamp.
  • the control device MP accesses the reference data RS1 when a first sensor SENS1 according to FIG. 1 is used Detection of the lamp type is provided. If, on the other hand, a first input device EXSW1 is provided (FIG. 2), the information INF1 supplied by EXSW1 is used directly - possibly in conjunction with the information INF2 - to select the control sequence data SEQ or the operating data (U or I) of the lamp.
  • FIG. 9 shows the relationship between a control signal sequence SEQ, the characteristic data of which is stored in the memory MEM, and the associated data (U, I) of the steady-state operation of the lamp L formed in one operating mode.
  • the two diagrams shown below in FIG. 9 show the course of control signal sequences (eg SEQ2, FIG. 8) that are output by the signal generator SG to the power electronics SNT (pin J2-4 or pin J2-22 in FIG. 5B, bottom left or in the middle at the entrance of SNT).
  • the two diagrams shown above in FIG. 9 show the profile of the lamp current IL or the lamp voltage UL (e.g. I2, U2), which are output by the signal generator SG to the power electronics SNT
  • the method according to the invention for operating an electric lamp of a predeterminable lamp type on a defined energy source therefore has the steps of acquiring first information INF1, which designates the lamp type of the lamp, and the step of actuating the lamp as a function of the first information, which designates the lamp type.
  • a predeterminable voltage can be used to detect the first information that denotes the lamp type U1 or a predeterminable current I1 are applied to the lamp, the first lamp-type information item being formed from the operating state of the lamp, which results in response to the application of voltage U1 or current I1.
  • information that designates a photometric, an electrical and / or a thermodynamic operating state can be used as the first piece of information.
  • the first information INF1 that designates the lamp type can be specified by an input device EXSW1, in particular by a switching element.
  • a second piece of information INF2 can be detected, which denotes one of several operating modes of the lamp after it has been put into operation, the energy supply to the lamp depending on the lamp type-specifying first information and depending on the second information that the Operation is referred to, controlled or regulated.
