Abstract
The utility model discloses an LED lamp tube, which comprises a light housing, wherein a PCB is arranged in the light housing, an LED lamp wick is arranged on the PCB board, at least two binding posts are arranged at the end part of the PCB, a bridge rectifier is arranged on the PCB, the input end of the bridge rectifier is connected with the binding posts, the positive output end thereof is connected with the positive electrode of the LED lamp wick, and the negative output end thereof is connected with the negative electrode of the LED lamp wick. The utility model provides a non-polarity LED lamp tube with convenient mounting.
Description
Technical field
The utility model relates to a kind of LED fluorescent tube.
Background technology
The LED wick is because little, the reaction speed of its volume is fast, long service life, power consumption is low and advantage such as pollution-free, to being widely used in each field so far, and especially on lighting apparatus, the existing trend that replaces fluorescent tube gradually of LED fluorescent tube.
A kind of common external power supply LED lamp comprises outside input power supply, converts alternating current to galvanic driving power, and the LED fluorescent tube.But this LED lamp exists certain inconvenience when mounted.
Because the LED wick has polarity, when its two ends added forward voltage, electric current flowed to negative electrode from LED wick anode, and the LED wick enters duty, converts electric energy to luminous energy, sends the light from ultraviolet to infrared different colours; But when the voltage that is added in its two ends was backward voltage, the LED wick can't conducting, so not luminous.
That is to say that the LED fluorescent tube also has polarity, when the LED fluorescent tube is installed, the both positive and negative polarity of LED fluorescent tube must be distinguished corresponding connection with the both positive and negative polarity of driving power output respectively, the LED wick could be lighted, otherwise the LED lamp can't operate as normal.
The utility model content
The utility model provides a kind of non-polar LED fluorescent tube easy for installation at deficiency of the prior art.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of LED fluorescent tube, comprise lamp housing, be provided with pcb board in the lamp housing, pcb board is provided with the LED wick, the end of pcb board is provided with at least two binding posts, also is provided with bridge rectifier on the described pcb board, and the input of described bridge rectifier links to each other with binding post, the forward output links to each other with the anode of LED wick, and inverse output terminal links to each other with the negative electrode of LED wick.During installation, binding post is linked to each other with the output of driving power.When the cathode output end of driving power is connected to bridge rectifier by any one binding post, bridge rectifier is according to forward conduction, and the characteristic of oppositely ending from the output of forward output, and flows to LED wick anode with this positive voltage.In like manner, when the cathode output end of driving power was connected to bridge rectifier by another binding post, bridge rectifier was exported this negative voltage from inverse output terminal, and flowed to LED wick negative electrode.Like this, no matter how the output of driving power is connected with binding post, and the voltage that is added to LED wick two ends at last all is forward voltage, and the LED lamp is operate as normal all the time.
In the technique scheme, the two ends of described pcb board respectively are provided with two binding posts and a bridge rectifier.During installation, the output of driving power is connected on any binding post that is no less than two, can makes LED lamp operate as normal, be applicable to the LED lamp of different structure.
In the technique scheme, the LED wick on the described pcb board all is connected in parallel.
Beneficial effect: the utility model compared with prior art has following beneficial effect:
(1) the utility model LED fluorescent tube is easy for installation, need not consider the branch of positive-negative polarity, is fit to average family or clerk and installs voluntarily or change.
(2) the utlity model has four binding posts, and can make LED lamp operate as normal, be applicable to the LED lamp of different structure as long as connect any two or more binding posts.
Description of drawings
Fig. 1 is the utility model circuit theory diagrams.
Fig. 2 is a user mode reference diagram of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
Referring to accompanying drawing 1~2, a kind of LED fluorescent tube, comprise the lamp housing (not shown), be provided with pcb board 1 in the lamp housing, pcb board 1 is provided with LED wick 2, and the end of pcb board 1 is provided with at least two binding posts 3, also be provided with bridge rectifier 4 on the described pcb board 1, the input of described bridge rectifier 4 links to each other with binding post 3, and the forward output links to each other with the anode of LED wick 2, and inverse output terminal links to each other with the negative electrode of LED wick 2.
During installation, binding post 3 links to each other with the output of driving power 5, and driving power 5 links to each other with external power source.
As a specific embodiment of the present utility model, the two ends of described pcb board 1 respectively are provided with two binding posts 3 and a bridge rectifier 4, and the LED wick 2 on the described pcb board 1 all is connected in parallel.
Like this, during installation, the output of driving power 5 is connected on the binding post 3 that is no less than two arbitrarily, can makes LED lamp operate as normal, be applicable to the LED lamp of different structure.
Certainly, also the utility model can be made the structure that two binding posts 3 and a bridge rectifier 4 only are set at an end of pcb board 1, be applicable to the monolateral mounted LEDs lamp of LED fluorescent tube.
Also the utility model can be made the structure that a binding post 3 and a bridge rectifier 4 respectively are set at the two ends of pcb board 1, be applicable to the common LED lamp that the LED lamp tube ends is all fixed.
Operation principle, when the cathode output end of driving power 5 is connected to bridge rectifier 4 by any one or more than one binding post 3, bridge rectifier 4 is according to forward conduction, the characteristic of oppositely ending, this positive voltage is exported from the forward output, and flowed to LED wick anode.In like manner, when the cathode output end of driving power 5 was connected to bridge rectifier 4 by other binding post 3, bridge rectifier 4 was exported this negative voltage from inverse output terminal, and flowed to LED wick negative electrode.Like this, no matter how the output of driving power 5 is connected with binding post 3, and the voltage that is added to LED wick 2 two ends at last all is forward voltage, and the LED lamp is operate as normal all the time.
