Be different from fluorescent tube by electron-beam excitation fluorescence, the photoelectric effect that light emitting diode (LED) utilizes junction rectifier to produce is come luminous.The optical wavelength that light emitting diode produces is more stable, and brightness is also controlled by electric current easily.Add that light emitting diode has cold light, volume is little and the electricity-saving characteristic, and the life-span be 10 times of fluorescent tube, therefore become gradually the market mainstream.
Traditional LED serial device provides electric current by an AC power, and this electric current at first needs by the bridge rectifier rectification, and several light emitting diodes of then just flowing through are so that light emitting diode is luminous in the equal energy of the positive negative cycle conducting of AC power.
Yet, above-mentioned LED serial device design, because after long-time the use, the light emitting diode problems of excessive heat can affect light emitting diode service life, therefore how to avoid the consumption of power, reduce simultaneously the component of light emitting diode, thereby reduce integral production cost and module microminiaturization, especially current led lamp field problem to be solved.
Summary of the invention
Main purpose of the present invention provide a kind of simple in structure, cost is low and can effectively fall the tandem device of alternative of lower powered consumption.
In order to achieve the above object, a kind of tandem device of alternative of the present invention, comprise one first～the 5th LED tandem group, certain electric current I C and an AC power, wherein this each LED tandem group comprises that several light emitting diodes are in series, and it is formed with the positive and negative electrode two ends; Wherein a LED tandem group negative pole is connected with the positive pole of the 2nd LED tandem group; The negative pole of the 2nd LED tandem group is connected with the 3rd LED tandem group is anodal; The 3rd LED tandem group negative pole is connected with the 4th LED tandem group is anodal; The 4th LED tandem group negative pole is connected with the negative pole of a LED tandem group and the positive pole of the 2nd LED tandem group; The 5th LED tandem group is anodal to be connected with the 2nd LED tandem group negative pole and the 3rd LED tandem group positive pole, and the negative pole of the 5th LED tandem group is connected with a LED tandem group is anodal, be connected with the 3rd LED tandem group negative pole, the 4th LED tandem group positive pole and should decide electric current I C, this AC power one end is connected with the positive pole of the 5th LED tandem group negative pole, a LED tandem group, and another end is then decided electric current I C with this and joined.
During enforcement, comprise a current-limiting resistance, in order to modulated current.
Useful technique effect of the present invention is, the lighting function of providing not only is provided the first～the 5th LED tandem group, more has the purpose of rectification concurrently, so can effectively reduce the quantity of overall structure electronic component, make cost, reduce structure space, more can fall low consumed power because electronic component reduces.
For further understanding the present invention, below lift preferred embodiment, cooperate diagram, figure number, concrete constitution content of the present invention and the effect reached thereof are described in detail as follows:
