Abstract
The utility model discloses a light-emitting diode tube device similar with a fluorescent tube. Under the situation that an external power distribution circuit of an existing fluorescent tube is not changed, a surge protector, which is arranged between power connection joints of a light-emitting diode tube formed by series connection of light-emitting diodes, acts for buffering power surge from an electronic ballast and then is connected in series with a bridge-type rectification circuit. High-frequency and high-voltage alternating current is rectified and changed into low-voltage and low-current direct current to be suitable for the light-emitting diodes. Meanwhile, a lighting signal connected in series with the electronic ballast is transmitted to a single-chip microcomputer. When an abnormal high-voltage signal of the lighting signal is sensed by the single-chip microcomputer, power supplied to a starting circuit which is formed in an MOSFET is timely processed and turned off. Then a pulse width modulation signal is outputted to the starting circuit in a way of simulating a power supply mode of a preheating type electron ballast so that voltage and current suitable for the light-emitting diodes are generated, and thus all the light-emitting diodes which are connected in parallel in high-impedance modules are enabled to emit light.
Description
Technical field
The utility model relates to a kind of circuit of light fixture, particularly the light-emitting diode lamp tube device of a kind fluorescent tube.
Background technology
Daylight lamp fixture mainly divides fluorescent tube and light fixture (comprising stabilizer), wherein the stabilizer in light fixture been has has been researched and developed dynamical electronic ballast has been installed, no matter electronic ballast has reached certain effect in efficiency, energy-saving and environmental protection, safety, but on fluorescent tube because the difference in structure and characteristic cannot find applicable substitute always, because fluorescent tube all has mercury content (as: T9 is that 15mg, T8 are that 5mg, T5 are can serious environment pollution after wrapping glass tube outside 3mg, T9 and breaking), the framework that LED is light source is take in existing exploitation.
Because commercially available fluorescent tube is all provided with apparatus for lighting up and electric stabilizer, electric stabilizer divides two classes, one, instantaneous starting type electric stabilizer (Instant Start): instantaneous starting without preheating type electric stabilizer, fluorescent tube instantaneous starting while lighting a lamp, its characteristic is to utilize high voltage startup fluorescent tube (starting resistor is approximately between 800V to 1, between 200V), light a lamp very easy, but easily cause fluorescent tube melanism, filament breaking, lamp tube service life reduces, if fluorescent tube coordinates traditional electrical magnetic-type, stabilizer is used, generally speaking, its point goes out number of times about 6, 000 left and right, fluorescent tube may produce melanism and fault, if use instantaneous starting type electric stabilizer, because it is former to light a lamp with high pressure, point goes out number of times about 2, 000～3, more than 000 time, fluorescent tube can produce melanism and life-span end of a period, two, the electric stabilizer of preheating start-up type (Pre-heated Start): the electric stabilizer of preheating start-up type provides best assurance to the protection of fluorescent tube, warm-up time can be by about 0.5 second to 2 seconds, and electric current is higher, and preheating is faster, higher with respect to the stress on filament (stress) voltage, life-span is shorter, and time expand makes stress (stress) voltage less, burn-out life can significantly improve, the declaration of the general manufacturer of the number of times of lighting a lamp is 10,000～15,000 time, and stabilizer itself, in general, the preheating type electric stabilizer life-span is about about 50,000 hours, comprehensive above stabilizer characteristic must overcome some on LED lamp source: when electric stabilizer is lit a lamp, have a high frequency (output frequency 2KHZ～50KHZ) high pressure (500V) starting resistor and some modulating voltage, electric stabilizer is different according to startup warm-up time or the mode of pipeline start up by preheating and without preheating startup or sequencing startup, for the article of more realistic demand are provided, creator researches and develops, to solve the problem easily producing in known use.
Utility model content
Main purpose of the present utility model is to provide the light-emitting diode lamp tube device of a kind fluorescent tube.Must first know the characteristic of commercially available various electronic ballasts, then go out the complete solar simulated fluorescent tube mode of lighting a lamp with the architecture design of microelectronic circuit, and then can directly substitute the product of fluorescent tube characteristic on existing market; Its electrical characteristic is light-emitting diode (LED) fluorescent tube designing according to fluorescent tube electrical characteristic completely, its the whole mechanism size even arrangement of bayonet peg is also the design of secundum legem fluorescent tube and having manufactured, be exactly to want to substitute commercially available traditional tube completely order, directly carry out the improvement of fluorescent tube, to reaching high-effect, energy-saving and environmental protection, improve the useful life of fluorescent tube, take it, to reach the light fixture that is more tending towards perfect be target.
For achieving the above object, the utility model is by the following technical solutions: do not changing under the power distribution circuit of original fluorescent tube outside, be provided with between the electric contact of a light-emitting diode lamp tube forming with light-emitting diode serial and be provided with a surge protecter, power surging as buffering from electric stabilizer, then be connected in series a bridge rectifier, the direct current that changes the alternating current arrangement of high-frequency and high-voltage into low pressure low current is to be applicable to light-emitting diode, the lighting signals that is connected in series with electronic stabilization is passed to a single chip microcomputer simultaneously, during via the abnormal high pressure signal of single chip microcomputer induction lighting signals, process at that time the power supply of closing the start-up circuit to forming with MOSFET, then imitate powering mode output pulse width modulation signal to start-up circuit of preheating type electric stabilizer, to produce voltage and the electric current that is applicable to light-emitting diode, allow with a high impedance module each lumination of light emitting diode in parallel.
For making your juror can further understand the utility model, be to reach technology, means and the effect that predetermined object is taked, hereby for a better feasible embodiment, and coordinate graphic being described in detail as follows, believe the purpose of this utility model, feature & benefits, when obtaining thus one deeply and concrete understanding.
