The emitter of described triode Q1 is by inserting the end of instrument transformer T1A to resistance R 7, the other end of described instrument transformer T1A inserts the end of filter inductance L2, the other end of described filter inductance L2 inserts: an end of the load that is made of semistor PTC parallel with one another, capacitor C 7, inductance L 6, the other end of described load inserts an end of capacitor C 4 and capacitor C 4 ' respectively, and described capacitor C 4 other ends insert the positive pole of Rectified alternating current of described full-bridge DB1 and the negative pole that the capacitor C 4 ' other end inserts the Rectified alternating current of described full-bridge DB1.
Energising back 220V alternating current is rectified into the Rectified alternating current of 220/2 amplitude through current-limiting resistance R1 and full-bridge DB1, filter a large amount of pulsation parts by electrochemical capacitor C2, form more stable near 300 direct current, the complementary oscillating circuit and the electric of giving the back again by filter inductance L1.L1 has stoped most high fdrequency component to flow to civil power, and electric current excessive when resistance R 1 prevents to power on damages full-bridge DB1.
Oscillatory process: complementary circuit is made of first complementary circuit (Q1, R7, R9, R5, T1C) and second complementary circuit (Q2, R8, R10, R6, T1B).
The 300V power supply passes through R3A, R3B gives capacitor C 6 chargings, trigger tube D7 punctures and conducting when being charged to the 25V left and right sides, its part part electric current is by triode Q2 base stage, make triode Q2 conducting, after the triode Q2 conducting, the collector current of triode Q2 is elementary by instrument transformer T1C's, the secondary induced current of instrument transformer T1C makes triode Q2 conducting strengthen again, triode Q1 is ended, after reaching capacity to triode Q2, the secondary inductive current direction upset of instrument transformer T1B, triode Q1 begins conducting, triode Q2 is become by conducting and ends, and finishes first concussion cycle to this.Later on to drive the lower whorl conductance at the induced current of instrument transformer T1B, instrument transformer T1C logical for triode Q1, triode Q2, the emitter current by triode Q1 and collector current and instrument transformer T1, ballast L2, load (L6, C7, PTC), dividing potential drop capacitor C 4, capacitor C 4 ' and power supply formation loop by triode Q2.
In course of normal operation, the electric charge on the capacitor C 6 is constantly discharged by diode D6 by triode Q2, and triggering signal disappears.Wherein: oscillation circuit and resonance frequency: ' constitute resonant tank by resistance R 2, capacitor C 9, instrument transformer T1A, filter inductance L2, capacitor C 7, semistor PTC, capacitor C 4, capacitor C 4.
By this intelligence temperature compensation circuit, when powering on because the cold filament of electricity-saving lamp in the rod pipe, mercury vapour in the rod pipe is unionized, the rod pipe does not also start (rod pipe equivalent resistance is very big), resonance frequency is by inductance (series value of T1A, L2) and electric capacity (series value of C9, C7 and C4+C4 ') and resistance decision thereof, f=1/ (2 π * LC).The resonance potential at rod pipe two ends is very high, and resonance current flows through filament, makes the filament heating produce electronic fog, is convenient to start subsequently.
Electronic fog around the hot filament is ionized startup under rod is managed high-frequency and high-voltage effect between two filaments, after the startup, filament becomes electrode, and the electric current that flows through electrode is that filament keeps suitable temperature.
Mercury vapour after the ionization is equivalent to inductance and voltage-stabiliser tube in the rod pipe, about pressure drop 90V.At this moment resonant inductance has been gone here and there the inductance of individual rod pipe equivalence again, and frequency reduces, and capacitor C 7 strengthens its capacitive reactance, adds the voltage step-down (90V) at rod pipe two ends, and the electric current of the filament of flowing through is reduced, and most of electric current is by tribute ion current-carrying.Energy exchange in the tribute ion current-carrying process shines on the pipe arm with purple light, manages after the three primary colors fluorescent powder buffering of green coating with white light to external radiation again.
Temperature-compensating: PTC is a thermo-compensator, and resistance was less when room temperature was low, and the current start electric current that flows through filament is increased; Resistance was bigger when room temperature was high, and the starting current that flows through filament is reduced.
PTC is connected in parallel on the C7 two ends, and the hard reboot that can change electric ballast (electricity-saving lamp) is preheating, postpones soft start, thereby has prolonged the useful life of fluorescent tube.
This electricity-saving lamp is compared with common cathode preheat technical energy saving lamp, has advantages such as low temperature easily starts, temperature is low, power consumption is little, brightness is high, the life-span is long, failure rate is low.
More than a kind of electricity-saving lamp that the utility model embodiment is provided be described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, part in specific embodiments and applications all can change, in sum, this description should not be construed as restriction of the present utility model.
