Abstract
The utility model provides a LED fluorescent tube that can compatible electronic ballast, this fluorescent tube through four diodes with the positive negative pole of LED array respectively with two pin connections of fluorescent tube, so no matter that inserts anodally in two pins, can both form a conductive path in the circuit of this fluorescent tube and come to supply power for the LED array to what make consumption need not differentiate positive negative pole when the installation fluorescent tube, improved the change efficiency of LED fluorescent tube.
Description
Technical field
The utility model relates to LED lamp tube technical field, in particular to a kind of can the LED lamp tube of compatible electronic barretter.
Background technology
Along with popularizing of LED technology, LED illumination is promoted widely, but, owing to leaving over when major part lighting supply (such as lamp socket) is all traditional lighting light fixture at present, if these lighting supplies of replacing on a large scale, then a huge loss beyond doubt. For this reason, many LED illumination lamp are designed to mutually mate with traditional lighting power-supply unit.
In traditional lighting field, fluorescent tube is an important set lights, accordingly, many illumination places are all provided with the fluorescent tube seat mated with traditional tube, these fluorescent tube seat two ends are provided with the socket of fixed lamp tube pin, and fluorescent tube seat inside is provided with electric ballast, and the socket that electric ballast is two ends after city's electricity of input is converted into direct current is powered, owing to fluorescent tube bulb does not have dividing of positive and negative electrode, just can be energized after the socket of the pin insertion fluorescent tube seat of such fluorescent tube.
In order to utilize traditional fluorescent tube seat as much as possible, present stage, many illuminating products of LED industry were all designed to fluorescent tube shape, but, need to distinguish positive and negative electrode due to LED lamp bead, there is a problem in the fluorescent tube therefore adopting LED lamp bead to make, be exactly LED lamp tube insertion lamp socket it is that easy positive and negative electrode connects instead, thus causes the LED lamp tube cannot normal operation. For this reason, current usual way removes the barretter of fluorescent tube seat, uses LED power instead and drives module, but this kind of way adds installation cost undoubtedly.
Summary of the invention
The purpose of this utility model be to avoid above-mentioned weak point of the prior art and provide a kind of can the electric ballast of compatible existing fluorescent tube seat, thus without the need to differentiating the LED lamp tube of positive and negative electrode when making installation.
The purpose of this utility model is achieved through the following technical solutions:
Provide a kind of can the LED lamp tube of compatible electronic barretter, comprise LED lamp bead array, the first pin and the 2nd pin, the positive pole of described LED lamp bead array connects the negative electrode of diode D1 and the negative electrode of diode D3 respectively, the anode of described diode D1 connects the first pin, the anode of described diode D3 connects the 2nd pin, the negative pole of described LED lamp bead array connects the anode of diode D2 and the anode of diode D4 respectively, the negative electrode of described diode D2 connects the first pin, and the negative electrode of described diode D4 connects the 2nd pin.
Described first pin and the 2nd pin comprise two contact pins, two contact pin short circuits of described first pin, two contact pin short circuits of described 2nd pin.
The tie point of the anode of described diode D1 and the negative electrode of diode D2 is connected to the first pin through current limliting circuit.
Described current limliting circuit comprises resistance parallel with one another and electric capacity.
It is connected with filtering circuit between the positive pole of described LED lamp bead array and negative pole.
Described filtering circuit comprises resistance parallel with one another and electric capacity.
The beneficial effects of the utility model: the utility model provide a kind of can the LED lamp tube of compatible electronic barretter, the positive and negative electrode of LED array is connected with two pins of fluorescent tube respectively by this fluorescent tube by four diodes, so no matter that access positive pole in two pins, can form a conductive path in the circuit of this fluorescent tube for LED array powers, thus make consumption do not need when installing fluorescent tube differentiate positive and negative electrode, it is to increase the replacing efficiency of LED lamp tube.
Accompanying drawing explanation
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in accompanying drawing does not form any restriction of the present utility model, for the those of ordinary skill of this area, under the prerequisite not paying creative work, it is also possible to obtain other accompanying drawing according to the following drawings.
Fig. 1 be of the present utility model a kind of can the structural representation of LED lamp tube of compatible electronic barretter.
Embodiment
With the following Examples the utility model is further described.
The utility model is a kind of can the embodiment of LED lamp tube of compatible electronic barretter, as shown in Figure 1, comprise LED lamp bead array, first pin and the 2nd pin, it is connected with filtering circuit between the positive pole of described LED lamp bead array and negative pole, the positive pole of described LED lamp bead array connects the negative electrode of diode D1 and the negative electrode of diode D3 respectively, the anode of described diode D1 connects the first pin, the anode of described diode D3 connects the 2nd pin, the negative pole of described LED lamp bead array connects the anode of diode D2 and the anode of diode D4 respectively, the negative electrode of described diode D2 connects the first pin, the negative electrode of described diode D4 connects the 2nd pin, the tie point of the anode of described diode D1 and the negative electrode of diode D2 is connected to the first pin through current limliting circuit.
In practical application, the first pin and the 2nd pin comprise two contact pins, two contact pin short circuits of described first pin, two contact pin short circuits of described 2nd pin.
As shown in Figure 1, filtering circuit comprises resistance R5, resistance R6 and electric capacity C4, and shown resistance R5 and resistance R6 is in parallel with electricity electric capacity C4 after connecting.
Current limliting circuit comprises resistance R1, resistance R2, resistance R3, electric capacity C1, electric capacity C2 and electric capacity C3, described R1, resistance R2, electric capacity C1 and electric capacity C2 be the first current limliting circuit in series mutually, described resistance R3 and electric capacity C3 forms the 2nd current limliting circuit, and the first current limliting circuit and the 2nd current limliting circuit are connected mutually.
After electric ballast converts industrial-frequency alternating current to high frequency alternating-current, by polarity free capacitor C1, C2, the capacitive reactance that C3 produces under certain exchange signal frequency limits the electric current being added in photodiode two ends, it is connected in parallel on electric capacity C1, C2, the resistance R1 at C3 two ends, R2, R3 mainly plays when power supply turns off to fall the charge discharging resisting above C1, C2, C3, after preventing capacitor charging, voltage superposition causes output voltage to raise and burns out photodiode, and the direct current that the electric current being limited becomes stable after D1D2D3D4 rectification after C4 filtering is that photodiode is powered.
