Description
Technical field
The present invention relates to a kind of LED lamp tube, particularly relate to a kind of LED lamp tube of replaceable electronic fluorescent fluorescent tube.
Background technology
Fluorescent lamp is the most frequently used illuminations of office space, shelter, and traditional fluorescent lamp generally adopts fluorescent tube, has the advantages such as energy-saving and environmental protection because of LED, along with the continuous maturation of LED technology, fluorescent tube gradually substitute by LED lamp tube.Because existing fluorescent lighting fixture is often provided with ballast, its output current is alternating current, and LED needs DC driven, for realizing replacing, needs to install electric power driving module in LED lamp tube.
Electric ballast (Electricalballast) is the one of ballast, refers to and adopts electronic technology to drive electric light source, makes it the electronic equipment producing required illumination.Corresponding is inductance type ballast (or ballast) with it.Modern fluorescent lamp more and more uses electric ballast, and light small and exquisite, even electric ballast and fluorescent tube etc. can be integrated, meanwhile, electric ballast can have starter function concurrently usually, so can save independent starter again.Electric ballast can also have greater functionality, such as can by improving the scintillation of power frequency or current waveform (as becoming square wave) improvement or elimination fluorescent lamp.
CN 101600288 A discloses a kind of circuit of electronic ballast being adapted to common dimmer for light control; comprise power supply input circuit, switching circuitry and resonance output loop; have between described power supply input circuit and switching circuitry and correct adjustment loop; resonance output loop simultaneously also comprises cathodic protection circuit, i.e. filament protective loop.
The same with above electric ballast; conventional fluorescent lamp ballast has with filament measuring ability mostly; when filament disconnection or short circuit, ballast all can be protected; so just need a kind of artifical resistance that can replace filament in replaced type LED; if the common resistance of this resistance substitutes, energy loss can be quite large.
The equivalent circuit theory figure of conventional fluorescent fluorescent tube as shown in Figure 1, fluorescent lamp comprises lamp base P1, P2, P3, P4, a filament is equivalent to resistance R1, R2, another root filament is equivalent to resistance R3, R4, lamp body is equivalent to resistance R, lamp base P1 is connected lamp body with lamp base P2 respectively by resistance R1, R2, and lamp base P3 is connected lamp body with lamp base P4 respectively by resistance R3, R4.
Summary of the invention
The invention provides a kind of LED lamp tube of replaceable electronic fluorescent fluorescent tube, this LED lamp tube directly can connect electric ballast, replaces conventional fluorescent fluorescent tube, and low in energy consumption.
A kind of LED lamp tube of replaceable electronic fluorescent fluorescent tube, comprise body, body has first end and the second end, first end is provided with the first lamp base and the second lamp base, second end is provided with the 3rd lamp base and the 4th lamp base, LED light module and electric power driving module is provided with in described body, described electric power driving module comprises first input end, second input, first output and the second output, first output is just being connected LED light module respectively with the second output, negative pole, first lamp base and the second lamp base connect first input end respectively by the first NTC thermistor and the second NTC thermistor, 3rd lamp base is connected second input respectively by the 3rd NTC thermistor with the 4th NTC thermistor with the 4th lamp base.
