Abstract
(EN)
One embodiment of the present invention relates to a driving device for a light emitting device. A driving device for the light emitting device according to one embodiment of the present invention comprises: a first switching unit including a plurality of first switching elements, wherein the plurality of first switching elements is connected to a power voltage unit which applies voltage; a light-emitting unit including a plurality of sub-light emitting units forming a string by connecting the light-emitting devices to each other, wherein each sub-light emitting device is connected to the plurality of first switching elements, respectively; a second switching unit including a plurality of second switching elements, wherein the plurality of second switching elements are electrically connected to the sub-light emitting units which are adjacent to each other when driving the second switching unit; and a control unit which generates a control signal according to voltage of the power voltage unit, controls the turning on/off of the first and the second switching elements by supplying the control signal to the first and the second switching unit, and controls light from the light-emitting unit by driving the connection state between sub-light emitting unit in series, parallel, or serial-parallel according to the control thereof.
