A lens includes a substrate, a light concentrating portion mounted on the substrate. The substrate includes a first substrate and a second substrate, the light concentrating portion includes a first light concentrating portion and a second light concentrating portion. The first light concentrating portion extends outward from the first substrate, the second light concentrating portion extends outward from the second substrate. The first light concentrating portion has a first axis, the second light concentrating portion has a second axis. The first axis and the second axis are configured in an angle and intersect in an extending direction thereof.

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.

Light-emitting device

A light emitting chip operating under a DC power supply is provided. The light emitting chip includes a substrate and a plurality of light emitting elements. The light emitting elements are arranged on the substrate, and have the same or different area sizes. The light emitting elements are driven by a single driving voltage or sectionally driven by a plurality of driving voltages.

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.
