Often being provided with ballast in existing fluorescent lighting fixture, its output electric current is alternating current, and LED needs DC driven, for realizing
Replace, need to install electric power driving module in LED lamp tube.
Electric ballast (Electricalballast) is the one of ballast, refers to use electronic technology to drive electric light source, is allowed to produce
The electronic equipment of raw required illumination.Corresponding is inductance type ballast (or ballast).Modern daylight lamp more and more makes
With electric ballast, light small and exquisite, it might even be possible to electric ballast is integrated with fluorescent tube etc., meanwhile, electric ballast
Generally can have starter function concurrently, so single starter can be saved again.Electric ballast can also have more multi-functional,
Such as can improve or eliminate the scintillation of daylight lamp by raising power frequency or current waveform (such as becoming square wave).
CN 101600288 A discloses a kind of circuit of electronic ballast being adapted to common dimmer for light control, including power supply input electricity
Road, switching circuitry and resonance output loop, have correction and adjust loop between described power supply input circuit and switching circuitry, with
The resonance output loop of Shi Suoshu also comprises cathodic protection circuit, i.e. filament protective loop.
The same with above electric ballast, conventional fluorescent lamp ballast has with filament detection function mostly, and filament disconnects or short circuit
Time ballast all can protect, so being accomplished by a kind of artifical resistance that can substitute for filament, this resistance in replaced type LED
If substituted with common resistance, energy loss can be the biggest.
The equivalent circuit theory figure of conventional fluorescent fluorescent tube as shown in Figure 1, fluorescent lamp includes lamp base P1, P2, P3, P4, one
Filament is equivalent to resistance R1, R2, and another root filament is equivalent to resistance R3, R4, and lamp body is equivalent to resistance R, lamp base P1 and lamp

25 DEG C of resistance values recorded, more preferably 2～12 Ω.
The present invention utilizes NTC thermistor to replace the filament of conventional fluorescent so that have the electric ballast of filament defencive function
Can normally work, owing to NTC thermistor declines along with temperature rises high resistance, produced power consumption reduces the most accordingly,
Reduce the overall power of LED lamp tube eventually.
Accompanying drawing explanation
Fig. 1 is conventional fluorescent fluorescent tube equivalent circuit theory figure.
Fig. 2 is the circuit theory diagrams of LED lamp tube of the present invention.
Detailed description of the invention
As in figure 2 it is shown, a kind of LED lamp tube, including lamp base P1, P2, P3, P4, LED light module 1 and power drives
Module 2, LED light module include substrate and the LED being fixed in the above, electric power driving module 2 include two outfans, the
One input 21 and the second input 22, two outfans connect the positive and negative electrode of LED light module 1 respectively.The present invention adopts
Electric power driving module 2 be high frequency electric source drive circuit, mainly the high frequency current transitions that electric ballast exports is become direct current
Electricity, supplies LED light module 1, and it can use LED drive circuit disclosed in CN203596948U.
LED lamp tube of the present invention is mainly used in replacing the fluorescent tube of conventional belt electric ballast, owing to existing electric ballast is big
