Definitions
- control of the at least one electronic switching element can be done directly or indirectly, d. H. with the interposition of a driver stage or not.
- the electronic ballast comprises a transformer having on the side of the switching element at least one primary winding and further comprises at least one secondary winding which emits the electrical energy to the lighting means.
- a microcontroller drives the electronic switching element. It is this z.
- B. a push-pull push-pull output stage of two switching elements, wherein the transformer is then designed so that it has two equal primary windings, which are each connected to one of the switching elements.
- a half-bridge output stage of two switching elements is used, wherein the switching elements via a node point directly or indirectly connected to each other, and wherein at least one primary winding of the transformer is connected to the node of the switching elements.
- the supply voltage is applied to a voltage divider, of which a tap is applied to an input of the micro-controller.
- the microcontroller can detect and monitor the supply voltage.
- the microcontroller can change the power output to the light source via the operating frequency, the duty cycle and the pulse packet distance, and can flexibly control the lamp by means of a skilful chronological parameter sequence.
- Figure 2 is an example of sequences of pulses delivered by the microcontroller at its outputs.
- the initially increased power can be returned to the normal operating level continuously or in sufficiently small steps after a predetermined time has elapsed, again changing the above-mentioned variables, in particular the operating frequency and / or the duty cycle.
- the above-mentioned free input 1 can also be used to connect a sensor for a control signal.
- these may be actuating signals for dimming the lamp.
- the dimming can be variable or in stages, again using the possibilities of power setting such as the variation of the operating frequency, the change of the duty cycle or the pulse width modulation concerning the pulse packets.
