Abstract
A high-frequency loop filter for a high frequency generator of an electrodeless lamp relates to the technical field of new light source illumination, The high-frequency loop filter comprises a framework (1) and an inductor (2), wherein the inductor (2) is fixed on the framework (1); the inductor (2) comprises a magnet ring (2-1) and a high-temperature insulating wire (2-2); and the high-temperature insulating wire (2-2) is wound on the magnet ring (2-1). By adopting the high-frequency loop filter, the high frequency generator of the electrodeless lamp works more stably, the reliability is improved, and the problem of turn-to-turn breakdown of the filter due to start-up of high voltage is avoided.
Description
Technical field:
The utility model relates to the new light sources lighting technical field, is specifically related to be used for the annular high frequency filter of high frequency generator of electrodeless lamp.
Background technology:
The output of HF lamp without electrodes radio-frequency generator needs a filter inductance, and the square wave of a pair of metal-oxide-semiconductor output is filtered just profound ripple.Normally used excellent mode filter be on the bar magnet around on enamelled wire, though this filter is simple, cheap; And also can reach filter effect; But have two defectives: 1) magnetic circuit of excellent mode filter is opened a way, and the magnetic line of force is through after the air transmitted, from the N level to the S level; If near have can magnetic conduction object near, like the iron sheet light fixture, the inductance value of filter will change; This variation, the little power output that then can have influence on electrodeless lamp can make lamp scintillation occur when serious, even can't start; When 2) electrodeless lamp starts, can produce the instantaneous pressure up to 3000V at the coil two ends of filter, the insulating barrier of enamelled wire is very thin; Damage easily in the winding process; Thereby reduced the insulating capacity of enamelled wire, often the high voltage when starting can produce discharge at injury region, thereby damages device.
The utility model content:
The purpose of the utility model provides the annular high frequency filter that is used for high frequency generator of electrodeless lamp, and it makes the high frequency generator of electrodeless lamp more stable work, improves reliability, has avoided making the problem of filter breakdown between adjacent turns owing to start high pressure.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises skeleton 1 and inductance 2; Inductance 2 is fixed on the skeleton 1, and described inductance 2 comprises magnet ring 2-1 and high-temperature insulation line 2-2, and high-temperature insulation line 2-2 is on magnet ring 2-1.
The utlity model has following beneficial effect: it makes the high frequency generator of electrodeless lamp more stable work, improves reliability, has avoided making the problem of filter breakdown between adjacent turns owing to start high pressure.
