摘要 |
A light emitting diode apparatus that includes a single DC/DC converter section that has two circuits connected in parallel: a flyback type boosting circuit and a boosting circuit. The former includes a transformer and a switching device and the like to boost DC voltage of a DC power supply, and the latter includes a transformer and a switching device and the like to do likewise. A control section carries out switching control of the switching devices and in such a manner that shifts from each other the phases of current Ida and current Idb to be supplied from the two boosting circuits and to a plurality of LED and the like connected in series in a light emitting section.
