Abstract
The utility model discloses an LED fluorescent tube drive circuit and an LED fluorescent tube. The drive circuit comprises bridge rectifier circuits and an LED drive module connected with an LED. The drive circuit is characterized in that the bridge rectifier circuits comprise a first bridge rectifier circuit and a second bridge rectifier circuit, and the first bridge rectifier circuit and the second bridge rectifier circuit share an output end which is connected an input end of the drive circuit. The LED fluorescent tube uses the drive circuit. Compared with the prior art, the LED fluorescent tube drive circuit uses a technical scheme that two rectifier circuits share the output end. No matter a conventional fluorescent lamp holder is supplied power at a single end or at two ends, and no matter a starter exists or not, the LED fluorescent lamp can be directly installed without modifying the lamp holder, so that the LED fluorescent tube drive circuit and the LED fluorescent tube have beneficial effect of convenient usage.
Description
Technical field
The utility model relates to lighting device, especially relates to a kind of LED fluorescent tube driving circuit and LED fluorescent tube.
Background technology
LED(Light Emitting Diode, light-emitting diode) fluorescent tube is applicable to the places such as hotel, market, office, workshop, parking lot, decorative lighting, lighting of home and room lighting.
All the time, the LED fluorescent lamp can not directly be installed on the traditional fluorescent lamp support and replace with traditional fluorescent lamp owing to be subjected to the impact of traditional fluorescent lamp optical circuit, and the building new in new place connects up, and the LED fluorescent lamp is installed and is not a problem.But in reducing energy consumption, just become problem with direct exchange of traditional fluorescent lamp pipe.Described problem has two, and problem one refers to the effective starter of traditional fluorescent lamp, is in attracting state at lower powered LED fluorescent tube when fluorescent tube throws light on, and the LED fluorescent tube can not be lighted.Problem two refers to that the tube stand circuit is a lot of on the market, and single-ended supply power mode is arranged, and both end power supplying is also arranged, and the inductor rectifier power supply is arranged, and the electron rectifier power supply is also arranged.Will be fit to above-mentioned various supply power modes with existing LED fluorescent tube, and directly exchange, be a large bottleneck of present LED fluorescent tube illumination.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of LED fluorescent lamp drive circuit and LED fluorescent tube, the problem of solution mounted LED lamp pipe on the traditional fluorescent lamp lamp bracket.
Technical problem of the present utility model is solved by following technological means:
A kind of LED fluorescent tube driving circuit, comprise bridge rectifier and the LED driver module that is connected with LED, described bridge rectifier comprises the first bridge rectifier and the second bridge rectifier, described the first bridge rectifier and the second bridge rectifier common output, described output is connected with the input of described driver module.
Preferably, described the first bridge rectifier and/or the second bridge rectifier are full bridge rectifier.
A kind of LED fluorescent tube comprises driving power and LED, and described driving power comprises claim 1 or 2 described LED fluorescent lamp drive circuits.
Compared with prior art, the utility model adopts the technical scheme of two-way rectification circuit common output, no matter the traditional fluorescent lamp lamp bracket is single-ended power supply or both end power supplying, no matter the having or not all to need not lamp bracket reequiped LED fluorescent lamp of the present utility model can directly be installed of starter, therefore has practical and convenient beneficial effect.
Description of drawings
Fig. 1 is the circuit theory diagrams of the utility model specific embodiment;
Fig. 2 a-2h is the supply power mode schematic diagram of the lamp bracket that can directly install of the fluorescent tube of the utility model specific embodiment.
Embodiment
Preferred embodiment the utility model is described in further detail for the below's contrast accompanying drawing and combination.
Present embodiment provides a kind of LED fluorescent tube of built-in driving power, this fluorescent tube comprises driving power and LED, LED is installed on the lamp plate, and driving power is connected to and exchanges between input and the LED, is used for exchanging specified direct current that input converts LED to and is input as LED and powers.
The schematic diagram of the drive circuit of the driving power of present embodiment as shown in Figure 1, it comprises bridge rectifier and the LED driver module that is connected with LED, described bridge rectifier is the Double-bridge type rectification circuit that is comprised of bridge rectifier A and bridge rectifier B, bridge rectifier A and bridge rectifier B common output, this output is connected with the input of described driver module; Wherein, bridge rectifier A and/or the preferred full bridge rectifier of bridge rectifier B.
Owing to adopt foregoing circuit, as long as bridge rectifier A be connected with bridge rectifier B in four inputs any two with exchange input and be connected and all can realize the normal power supply of LED and electricity (lighting) is measured LED, shown in Fig. 2 a-2h, therefore, as long as fluorescent tube is made the profile identical with the traditional fluorescent lamp fluorescent tube, size, interface specification, no matter lamp bracket is single-ended power supply, both end power supplying, also no matter whether starter disassembles, need not the circuit of lamp bracket is reequiped, directly replacement is installed LED fluorescent lamp of the present utility model and can be lighted use, and is convenient and swift.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of ordinary skill in the field; without departing from the concept of the premise utility; can also make some being equal to substitutes or obvious modification, and performance or purposes are identical, all should be considered as belonging to protection range of the present utility model.
