Zusammenfassung:PROBLEM TO BE SOLVED: To enable more enhancement of the efficiency as compared with prior arts.SOLUTION: A lighting device 1 is configured so that only one of a first current controller 11 and a charging current controller 12 is allowed to operate in any operation mode of first to fourth modes. That is, the lighting device 1 can enhance the efficiency more greatly as compared with a prior art described in Patent Document 1 because the first current controller 11 and the charging current controller 12 are not contained in the same closed circuit.SELECTED DRAWING: Figure 1 【課題】従来例と比較して効率の向上を図る。【解決手段】本実施形態の点灯装置1は、第1モードから第4モードの何れの動作モードにおいても、第1電流制御部11と充電電流制御部12の何れか一方のみしか動作させないように構成される。つまり、本実施形態の点灯装置1は、第1電流制御部11と充電電流制御部12が同一の閉回路に含まれることがないので、特許文献1記載の従来例と比較して効率の向上を図ることができる。【選択図】 図1
