The utility model provides a bendable light emitting device, and it includes a flexible upper cover, a power supply unit and a luminescence units. Flexible upper cover includes an accommodating space and a pulling part. Power supply unit is arranged in what accommodating space, and it includes one first anode and one first cathode. Luminescence unit is arranged on what power supply unit, separately includes one second anode and one second cathode. Second anode of the first cathode of the constant conducting power supply unit of the second cathode of luminescence unit, luminescence unit is then connected or is not turned on the first anode of power supply unit according to the actuation of pulling part, and then switches luminescence unit and shine or do not shine. Power supply unit and luminescence unit all have frivolous size, thereby enable bendable light emitting device that can use with taking.本新型提供一可撓式發光裝置，其包含一可撓上蓋、一供電單元以及一發光單元。可撓上蓋包含一容置空間及一扳動部。供電單元設置於容置空間內，其包含一第一正極及一第一負極。發光單元設置於供電單元上，其分別包含一第二正極及一第二負極。發光單元之第二負極恆常導通供電單元之第一負極，發光單元之第二正極則依據扳動部之作動而導通或不導通供電單元之第一正極，進而切換發光單元發光或不發光。供電單元及發光單元皆具輕薄尺寸，藉此令可撓式發光裝置可隨攜即用。
