Abstract: A light-emitting device includes a power module, a first light-emitting module, a second light-emitting module, a third light-emitting module, and a control module. The power module is configured to rectify an AC voltage for providing a periodic driving voltage. The first, second, third light-emitting modules are connected in series. The control module is configured to make the first, second, third light-emitting modules being driven by the driving voltage in response to different driving stages in a cycle period of a driving voltage. An average-diode-junction-area of the first light-emitting module is different from an average-diode-junction-area of the second light-emitting module or an average-diode-junction-area of the third light-emitting module.

Abstract: An illumination structure including an illumination module, a light base and a cover is provided. The light base includes a cylindrical shell and an electrical connector, wherein the cylindrical shell is used for receiving and supporting the illumination module. A first end of the cylindrical shell has a first edge including a plurality of protrusions. A second end of the cylindrical shell is connected to the electrical connector. The cover has a second edge including a plurality of recessions. Each recession is complementary in shape to a corresponding protrusion, so that the protrusions are received in corresponding recessions respectively.
