| Zusammenfassung: | The invention provides an electrical device and an electrical device system capable of improving visibility when a battery pack is replaced in a dark place. This electrical device (1) is provided with a battery pack mounting section (2b), a main light-emitting diode (11), and a sub-light-emitting diode (15). The main light emitting diode (11) is turned on by the power of the battery pack (7). The secondary light emitting diode (15) illuminates the battery pack (7) mounted on the battery pack mounting part (2b) or the battery pack mounting part (2b). The sub-light-emitting diode (15) is turned on when the voltage or capacity of the battery pack (7) does not reach a predetermined value. The sub-light-emitting diode (15) is turned on by the power of another power supply unit (12) different from the battery pack (7).
本发明提供一种能够提高昏暗场所内的电池组更换时的视认性的电气设备及电气设备系统。本发明的电气设备(1)包括电池组安装部(2b)、主发光二极管(11)以及副发光二极管(15)。主发光二极管(11)通过电池组(7)的电力来点亮。副发光二极管(15)照亮电池组安装部(2b)上安装的电池组(7)或者电池组安装部(2b)。副发光二极管(15)在电池组(7)的电压或容量已不到规定值时点亮。副发光二极管(15 |
