    Abstract: A light-emitting device includes an autotransformer, a circuit module and a light-emitting module. The autotransformer includes a first positive conductive wire for receiving a first input voltage within a first predetermined voltage range, a second positive conductive wire for receiving a second input voltage within a second predetermined voltage range, and a common negative conductive wire electrically mated to the first positive conductive wire and the second positive conductive wire. The first predetermined voltage range is larger than the second predetermined voltage range. The circuit module includes a driver electrically connected to the autotransformer, and a predetermined operating voltage value for driving the driver is substantially within the second predetermined voltage range. The light-emitting module is electrically connected to the driver. Therefore, one of both the first and the second positive conductive wires along with the common negative conductive wire are electrically connected to an AC power source.

    Abstract: 一種發光裝置包括自耦變壓器、電路模組及發光模組。自耦變壓器包括一用於接收一第一預定範圍電壓值的第一正極導線、一用於接收一第二預定範圍電壓值的第二正極導線、及一同時電性配對於第一正極導線及第二正極導線的共用負極導線,且第一預定範圍電壓值大於第二預定範圍電壓值。電路模組包括一電性連接於自耦變壓器的驅動器,其中驅動器的一預定操作電壓值落在第二預定範圍電壓值內。發光模組電性連接於驅動器。藉此,發光裝置可以依據交流電源所提供的不同範圍的供應電壓值,以選擇性將第一正極導線直接電性連接於高電壓交流電源、或將第二正極導線直接電性連接於低電壓交流電源。
