Definitions
- the invention relates to high power discharge lamps, in particular iodide lamps of 2000 Watts, and, more particularly, the ignition circuit necessary to operate such a lamp.
- the initiators for discharge lamps can be produced in different ways. Since the lamp is generally connected in series with an induction coil, the latter can, for example, be provided with an intermediate plug and be connected so as to constitute a voltage step-up auto-transformer thus making it possible to increase the voltage. applied to the lamp terminals.
- Such an auto-transformer is an expensive, heavy and bulky component.
- such a circuit may not function properly if it is disposed at a distance substantially distant from the lamp which it controls.
- This electronic initiator includes a thyristor, the ignition angle of which varies as a function of the network voltage.
- this igniter generates large transient currents before delivering the required ignition pulse and thereby unnecessarily consumes a certain power.
- the initiator must deliver a voltage pulse whose peak value is at least equal to 1100 Volts and the duration, measured at 900 Volts, is greater than 100 us .
- the subject of the present invention is an electronic initiator having the required characteristics and making it possible to obviate the aforementioned drawbacks, while being simple and inexpensive to produce in series and nevertheless having increased reliability compared with known initiators.
- the initiator which is arranged in parallel with the lempe which it controls, comprises a capacitor connected in series with a triac, and a branch including in series a first resistor, a zener diode and a second resistor, this branch being connected between the junction point of the capacitor and the triac, and one of the terminals of the voltage source.
- the triac control circuit is connected to the junction point of the second resistor and the zener diode, and includes a diac.
- the single Figure shows the electrical diagram of an initiator according to the present invention.
- the discharge lamp 1 is connected in series to an induction coil 2, the assembly being connected to the terminals of an alternating voltage source delivering for example 380 volts.
- the igniter 3 is arranged in parallel with the discharge lamp 1. It comprises a capacitor 4 in series with a triac 5.
- the triac 5 control circuit is connected to the junction point of the second resistor 9 and the zener diode 8. It comprises a diac 11 and a capacitor 12, the latter being arranged in parallel with the resistor 9.
- the zener diode 8 makes it possible to directly control the opening angle of the triac 5.
- the zener diode 8 can advantageously be replaced by several zener diodes, in particular three, connected in series.
