DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiment 1

(14) The present disclosure is described in detail below with reference to FIGS. 1-10.

(15) This embodiment provides a light emitting device 10 with an adjustable optical angle, and the light emitting device 10 comprises a base 20, a light source 30, and a panel 40. One of the light source 30 or the panel 40 is movably mounted on the base 20. The panel 40 comprises a plurality of transmission areas with different lens angles, and the light source 30 or the panel 40 is moved so that a light emitting area of the light source 30 is located to correspond to a specific transmission area of the plurality of transmission areas. Further, the light source 30 comprises a plurality of light emitting matrices 301 arranged at equal intervals. The panel 40 comprises a plurality of first transmission areas 401 arranged at equal intervals, and a distance between two adjacent light emitting matrices 301 of the plurality of light emitting matrices 301 is equal to a distance between two adjacent first transmission areas 401 of the plurality of first transmission areas 401. The panel 40 comprises one or more second transmission areas 402 respectively disposed between the two adjacent first transmission areas 401 of the plurality of first transmission areas 401 (i.e., the plurality of first transmission areas 401 and the one or more second transmission areas 402 are arranged alternately). The plurality of first transmission areas 401 and the one or more second transmission areas 402 have different transmission angles, so that the light emitting device 10 has a plurality of transmission angles. The user moves the light source 30 or the panel 40 so that the light emitting area of the light source 30 is located to correspond to the plurality of first transmission areas 401 or the one or more second transmission areas 402, thereby reducing a need for the user to purchase multiple lamps and improving the user experience. A transmission angle of the plurality of first transmission areas 401 is 9045, and a transmission angle of the one or more second transmission areas 402 is 9090.
