Description
Technical field
The present invention relates to a kind of AC light-emitting body and AC illuminator, refer to that especially a kind of utilization has AC light-emitting body and AC illuminator that the rectifier stack of high reverse-breakdown voltage and low forward cut-in voltage characteristic carries out rectification.
Background technology
Along with the stable development of photoelectricity science and technology, belong to light-emitting diode (the LightEmitting Diode of one of light emitting source; LED) be applied to various electronic applications in large quantities, and in photoelectric field, occupy critical role, just because of this, countries in the world manufacturer there's no one who doesn't or isn't drops into the exploitation of ample resources in correlation technique, and January 26 2005 Christian era Korea S's Seoul semiconductor and the product presentations of American I II-N Technology illustrated that more alternating current of led (AC LED) commercialization future must be towards the trend of global exploitation.
And so far from the technical development of the luminous micromeritics of alternating current, existing a kind of improve that early stage alternating current diode produced can't be when alternating current positive-negative half-cycle signal be imported all can luminous (full-time luminous) the bridge-type alternating current of led structure of problem, it mainly utilizes the design concept of Wheatstone bridge (Wheatstone Bridge), so that alternating current of led each moment when alternating current positive-negative half-cycle signal is imported only has the luminous phenomenon of the luminous micromeritics of alternating current of sum 1/2 to be improved.
But because the rectifier stack in this kind bridge-type alternating current of led structure directly uses the luminous micromeritics of alternating current, therefore can produce two major defects, one, because single rectifier stack (single the luminous micromeritics of alternating current) reverse bias holding capacity is not good, so the quantity of employed rectifier stack can't reduce, promptly, must be connected on the arm of Wheatstone bridge by many luminous micromeritics of alternating current and just can bear the reverse bias that applies by alternating current, with civil power 110V, by the reverse bias peak value that ac signal applied be about 156V (110 *
), therefore, the luminous micromeritics of alternating current in ac signal plus or minus path that half-wave is flowed through needs about 20 altogether, partially contrary on average to bear, avoid by the contrary risk that punctures partially, so, the rectifier stack sum needs 20 * 2=40 (ac signal is just reaching the luminous micromeritics of alternating current in negative path that half-wave is flowed through) approximately, then constrained to 110V/3.1V (actuation voltage of every luminous micromeritics of alternating current)-20 (in order to the luminous micromeritics quantity of the alternating current of rectification)=15 in order to the luminous micromeritics quantity of luminous alternating current, hence one can see that, can produce in order to the quantity of the luminous micromeritics of alternating current of rectification much larger than situation in order to the quantity of the luminous luminous micromeritics of alternating current, and because rectification is identical with luminescence component (the luminous micromeritics of the alternating current) energy that both consumed, so the ratio that can make input power be wasted in rectifier stack remains high, and produces the not good facts of whole efficiency; Its two, though compared to the design of early stage alternating current diode, its light-emitting area is existing to be increased, but still rectifier stack quite a lot is arranged because of in the contrary waste that can luminously not cause whole light-emitting area when inclined to one side.
Therefore, how to provide a kind of rectifier stack can bear the reverse bias that applies by alternating current by minority, with the raising whole efficiency, and the alternating current diode of increase light-emitting area, problem demanding prompt solution in the real field for this reason.
