Abstract
The utility model discloses an anti-interference circuit for high-frequency electrodeless lamps. The anti-interference circuit comprises two stages of filter circuits which are connected in series, and each stage of filter circuit comprises a high-capacity inducer and capacitors, which are connected in parallel. Since the anti-interference circuit provided by the scheme uses the high-capacity inducers and the capacitors to form the two stages of filter circuits, the anti-interference performance of the anti-interference circuit is good, and the anti-interference circuit can prevent the electromagnetic interference in a power grid from being inputted into the circuit of a high-frequency electrodeless lamp as well as the electromagnetic interference of the circuit of the high-frequency electrodeless lamp from being fed back into the power grid.
Description
Technical field the utility model relates to the lighting circuit field, is specifically related to a kind of HF lamp without electrodes anti-clutter circuit.
The background technology HF lamp without electrodes is to utilize a kind of new type light source of fluorescent tube gas discharge and two principle combinations of high-frequency electromagnetic induction.HF lamp without electrodes mainly is made up of high-frequency pole-free circuit for lamp, coupler and bulb three parts that scribble three primary colors fluorescent powder, its operation principle is: behind the supply voltage of input certain limit, high frequency power generator produces high-frequency electrical energy and gives coupler, make the gas avalanche ionization in the bulb form plasma, spontaneous radiation went out ultraviolet ray when the plasma excited atom was returned ground state, and the fluorescent material of bulb inner wall is subjected to ultraviolet ray excited and sends visible light.
The shortcoming of HF lamp without electrodes is the problem that the high-frequency pole-free circuit for lamp may bring electromagnetic interference, therefore need in the high-frequency pole-free circuit for lamp, increase filter circuit, filter circuit can prevent that the electromagnetic interference in the electrical network is input in the high-frequency pole-free circuit for lamp, also can stop high-frequency pole-free circuit for lamp electromagnetic interference to feed back in the electrical network.
Summary of the invention the utility model provides a kind of electromagnetic interference that is used for preventing electrical network to be input in the high-frequency pole-free circuit for lamp, also can be used for stoping high-frequency pole-free circuit for lamp electromagnetic interference to feed back to HF lamp without electrodes anti-clutter circuit in the electrical network.
The technical scheme that the utility model is taked is: the utility model circuit comprises inductor, capacitor, and described HF lamp without electrodes anti-clutter circuit is composed in series by the two-stage filter circuit, and every grade of filter circuit is all composed in parallel by jumbo inductor and capacitor.
The capacity of described inductor is greater than 10mH, and capacitor volume is greater than 0.22 μ F.
The HF lamp without electrodes anti-clutter circuit that the utility model scheme provides uses big capacity inductor and capacitor to form the two-stage filter circuit, its anti-interference is good, can prevent that the electromagnetic interference in the electrical network is input in the high-frequency pole-free circuit for lamp, also can stop high-frequency pole-free circuit for lamp electromagnetic interference to feed back in the electrical network.
Description of drawings now is further elaborated the utility model in conjunction with the accompanying drawings:
Fig. 1 is a schematic diagram of the present utility model.
Embodiment as shown in Figure 1, the utility model mainly is composed in series by first order filter circuit 1 and second level filter circuit 2, first order filter circuit 1 is composed in parallel by inductor LF1, capacitor C1, and second level filter circuit 2 is composed in parallel by inductor LF2, capacitor C2, C3.The capacity of the inductor that adopts in the circuit is greater than 10mH, and capacitor volume is greater than 0.22 μ F.
