Problems solved by technology

At this time, the peak-to-peak voltage and peak-to-peak current of the power device of the inverter have dropped to the lowest point of the lamp cold start state, and then the power device of the inverter is provided with a constant high voltage and the rated current required by the lamp load. When the whole machine is turned off, it is very easy to damage the components inside the machine

Abstract

The invention discloses an electrodeless lamp with a high-frequency generating circuit and relates to an illumination device. The electrodeless lamp with the high-frequency generating circuit comprises an alternating current power supply, an active power factor correction circuit, a high-frequency pulse generator, an inverter, a cross-zero trigger, an impedance matching circuit, a power supply isolation module and a time delay circuit, wherein when a normal pulse waveform is input into a power device of the inverter through controlling, the electricity is supplied to the power device of the inverter; and when the time delay circuit detects that the current is zero, the power supply is cut off so as to ensure that the power device of the inverter and the high-frequency pulse generator securely work all the time in modes of high performance, high reliability and long service life, therefore, the service life of the electrodeless lamp can be greatly prolonged.

Description

technical field [0001] The invention relates to an illuminating device, in particular to a high-frequency generating circuit of an electrodeless lamp. Background technique [0002] With the continuous progress of society, the technology of electrodeless lamps has also been continuously developed. The existing electrodeless lamps supply power to the high-frequency pulse generator when starting up. Due to the layout of the electrodeless lamp circuit board, there are inevitably distributed capacitance and distributed inductance. , coupled with the impact of the discreteness of components, it takes a certain amount of time for the waveforms required by the power devices of the inverter to be supplied normally. The high-frequency pulse generator outputs waveforms to the inverter and directly supplies power to the inverter. The power device and high-frequency pulse generator cause permanent damage, so the high-frequency pulse generator cannot supply power to the power device of th...
