| Zusammenfassung: | A lighting system (1) having a high intensity discharge lamp (16) mounted replaceably in a holder (25) which connects to an electronic control (8) which includes a variable frequency generator (10), a joint operating circuit extends from the lamp to the control; the control is arranged to sweep over a predetermined range of frequencies to produce by means of a resonant circuit which includes in the circuit (22) capacitance (12, 13, 21) which is at least partly in or on the lamp. Removal of the lamp from the system prevents the production of the resonant high voltage ensuring improved safety. |
