Abstract

The invention is suitable for the technical field of illumination devices, and discloses an automatically-focusing light-projecting device. The automatically-focusing light-projecting device comprises a light-projecting barrel, a light-condensing lens arranged on the end portion of the light-projecting barrel, a light source assembly slidably arranged in the light-projecting barrel, a light-reflecting cup fixedly connected to the light source assembly, and a telescopic drive element connected to the light source assembly and used for driving the light source assembly to slide along the light-projecting barrel. The automatically-focusing light-projecting device provided by the invention realizes automatic light distribution by virtue of the telescopic drive element; when a transparent bubble liner in a suspended light-emitting device moves up and down with the changes of an electromagnetic flux, the telescopic drive element synchronously adjusts and focuses; the automatically-focusing light-projecting device is capable of automatically adjusting light distribution, simple in structure, excellent in reliability, abundant in function, good in beautifying effect, and convenient to install, place and carry.
