Abstract

The invention discloses a zoom down lamp for a stage, which comprises a cylindrical shell, the front face of the cylindrical shell is provided with an opening, the back of the cylindrical shell is provided with an exhaust fan communicating with the interior of the cylindrical shell, the inner wall of the opening of the cylindrical shell is in threaded connection with a connecting shell, a zoom adjusting mechanism is installed in the cylindrical shell, and an LED bulb is installed on the zoom adjusting mechanism. The front face of the connecting shell is provided with an opening, the outer wall of the opening is in threaded connection with a lamp cover, the back face of the lamp cover is provided with an opening, the front face of the lamp cover is provided with a light outlet, and a light gathering cover is installed between the lamp cover and the connecting shell. The zoom adjusting mechanism comprises a U-shaped plate, the back of the U-shaped plate is fixedly connected with a motor, the inner wall of the U-shaped plate is rotationally connected with a lead screw in shaft connection with the motor, the front face of the U-shaped plate is slidably connected with a guide rod in a penetrating mode, and the outer wall of the lead screw is connected with a rectangular plate in a threaded penetrating mode. The invention relates to the technical field of down lamps. According to the stage zoom down lamp, the problems that the condensation size of the stage down lamp cannot be adjusted, and a plurality of down lamps with different specifications of focal lengths are generally needed to achieve zooming under the synergistic effect are solved.

Description

technical field [0001] The invention relates to the technical field of downlights, in particular to a zoom downlight for a stage. Background technique [0002] In the prior art, the spotlight size of the stage downlight cannot be adjusted, and usually requires the synergy of multiple downlights with different focal lengths to achieve zooming, so we invented a stage zoom downlight that can adjust the focal length by itself. Contents of the invention [0003] In order to solve the problem that the spotlight size of stage downlights cannot be adjusted, usually multiple downlights with different specifications and focal lengths need to cooperate to achieve zooming. The object of the present invention is to provide a zoom downlight for stage use. [0004] In order to achieve the above object, the present invention adopts the following technical solution: a zoom downlight for a stage, including a cylindrical housing, the front of the cylindrical housing is provided with an openi...
