Description
Technical field
The utility model relates to a kind of tube circuit, and especially a kind of electric ballast replaces LED lamp tube circuit.
Background technology
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.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; Also fluorescent lamp is made to use DC power supply by power inverter process.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.
At present, the connected mode that electric ballast replaces LED lamp tube circuit mainly contains two kinds, and one is non-capacitive, direct rectification, filtering (see Figure of description 2); Another kind is through isolation capacitance C2, then rectification, filtering (see Figure of description 3); The electric ballast that circuit shown in Fig. 2 adapts to is many; and the circuit shown in Fig. 3 is more responsive mainly due to the protection testing circuit of part electronic ballast for fluoresent lamp; after isolation capacitance, its flip-flop is completely isolated, and due parameter cannot be detected.But after the circuit shown in Fig. 3 has isolation capacitance, fluorescent tube misconnection is played a good protection, such as directly access in the circuit of civil power or Inductive ballast driving.Circuit shown in Fig. 3, due to the buffer action of electric capacity, can protect fluorescent tube to damage.And the circuit shown in Fig. 2 will burn LED lamp bead and fuse, fluorescent tube was lost efficacy.
Prior art can not meet the needs of people, and for making up prior art deficiency, the utility model aims to provide a kind of electric ballast and replaces LED lamp tube circuit.
For achieving the above object, the utility model is by the following technical solutions: a kind of electric ballast replaces LED lamp tube circuit, and its electronic component comprises fuse F1, diode D1, diode D2, diode D3, diode D4, light-emitting diode D5, electric capacity C1, electric capacity C2 and resistance R3; Described diode D1 and diode D3 is in parallel with the diode D2 connected and diode D4 again after connecting; Described electric capacity C1 is connected with diode D1 and diode D2 by wire; Described light-emitting diode D5 connects diode D3 and diode D4; Described electric capacity C1 is in parallel with light-emitting diode D5.
As further technical scheme of the present utility model: described fuse F1 one end connects the connection wire of diode D1 and diode D2, and the other end is connected with connector JP1.
Further, after described electric capacity C2 is in parallel with resistance R3, one end connects connector JP2, and another end is connected with the connecting line of diode D3 and diode D4.
As optimisation technique scheme of the present utility model: described electric capacity C2 value is 0.1uF-0.68uF, resistance R3 value is 10k Ω-20k Ω.
Compared with prior art, the beneficial effects of the utility model are: this electric ballast replaces LED lamp tube circuit, resistance R3 is incorporated to while adding electric capacity C2, regulate electric capacity C2 and resistance R3, and then change the bad situation that prior art burns LED silk and fuse, and have after isolation capacitance, the misconnection for fluorescent tube plays a good protection, and reaches the object of two kinds of benefit compatibilities; Whole circuit connects simple, is easy to realize, and conveniently promotes the use of.
