Abstract
A contactless electronic starter is composed of SCR T, diodes D1, D2, D3, voltage-regulator tube DW, resistors R1, R2, R3 and capacitor C1, in which, the control electrode of the SCR is connected to the positive electrode of the voltage-regulator tube DW, which is composed of diode D1 and resistor R1 connected in series, and resistor R3 is connected between the control electrode and the negative electrode of the SCR, which is controlled by the voltage-regulator tube to turn on and off, and the capacitor C1 discharges to the conducting SCR to increase the preheating current of filament, so that the fluorescent lamp can be started quickly and work reliably in 160-250V range.
Description
The utility model relates to a kind of contactless electron starter.
Existing contactless electron starter cost is higher, and the starting voltage scope is narrower, and its build-up of luminance speed is also fast inadequately.
The purpose of this utility model provides a kind of with low cost, starting voltage wide ranges, the fireballing contactless electron starter of build-up of luminance.
Contactless electron starter provided by the utility model is mainly by controllable silicon T, diode D1, D2, D3, voltage-stabiliser tube DW, resistance R 1, R3 and capacitor C 1 are formed, the control utmost point of controllable silicon T is connected on and resistance R 1, on the voltage-stabiliser tube DW positive pole that diode D1 is cascaded, resistance R 3 is connected in parallel between the controllable silicon T control utmost point and the negative electrode, by the conducting of voltage-stabiliser tube DW control controllable silicon T with end, with the positive pole of capacitor C 1 be connected in parallel on joint A1 after the negative pole of diode D3 is connected, on the A2, capacitor C 1 positive pole is connected in again on the anode of controllable silicon T simultaneously, controllable silicon T is in conducting state, capacitor C 1 discharge, to increase the preheat curent of filament, make fluorescent tube also build-up of luminance rapidly under low voltage.
The utlity model has advantages such as circuit is simple, with low cost, the starting voltage scope is 160V-250V, and build-up of luminance speed is fast, the life-span is grown, do not glimmer.
The utility model is described in further detail in conjunction with the accompanying drawings.
Fig. 1-be the utility model electrical schematic diagram.
As shown in the figure, the utility model is with diode D1, resistance R 1, voltage-stabiliser tube DW, be attempted by filament joint A1 after resistance R 3 series connection, on the A2, the controllable silicon T control utmost point is connected with voltage-stabiliser tube DW is anodal, controllable silicon T anode is connected between the negative pole of the anodal and diode D3 of the capacitor C that is cascaded 1, the positive pole of the negative pole of capacitor C 1 and diode D3 respectively with filament joint A1, A2 connects, when the alternating current of importing filament joint A1 is a negative half period, not conducting of diode D1, the control utmost point of controllable silicon T is in cut-off state because of can not get trigger current, and this moment, electric current charged to capacitor C 1 by D3.Have only when the alternating current that is input to joint A1 is positive half cycle, diode D1 conducting, electric current is by resistance R 1, when voltage-stabiliser tube DW both end voltage is raised to certain value, voltage-stabiliser tube DW conducting, resistance R 3 both end voltage are added on the controllable silicon T, trigger the controllable silicon conducting, capacitor C 1 is also to controllable silicon T discharge, the very fast preheating starter of filament at this moment simultaneously.In the present embodiment, resistance R 2 is attempted by between voltage-stabiliser tube DW positive pole and the joint A2, behind the fluorescent lamp starter, the voltage of joint A1, A2 is reduced to about 108V, because the dividing potential drop effect of resistance R 2, make the voltage reduction of voltage-stabiliser tube DW and be in cut-off state, controllable silicon T also is in cut-off state, even the alternating current that is added on the A1 is positive half cycle, controllable silicon T can not conducting, capacitor C 1 can not be discharged simultaneously, thereby guarantees the work of fluorescent lamp normal reliable.This starter is attempted by capacitor C 2 on filament joint A1, the A2, can play the radio interference effect that suppresses.
Claims (3)
1, a kind of contactless electron starter of forming by controllable silicon T, diode, be attempted by on filament joint A1, the A2 after it is characterized in that diode D1 and resistance R 1, voltage-stabiliser tube DW, resistance R 3 being connected, diode D2 is cascaded with controllable silicon T and links to each other with filament joint A1, A2, the control utmost point of controllable silicon T is connected on the positive pole of voltage-stabiliser tube DW, capacitor C 1 anodal be connected in parallel on filament joint A1, the A2 after the negative pole of diode D3 is connected, and the positive pole of capacitor C 1 is linked to each other with controllable silicon T anode.
