Abstract

The invention relates to a lamp with adjustable light spot size. The reflector includes left and right half reflectors which are respectively rotatably connected to the shell of the lamp; Part main body, guide column, threaded hole and adjustment screw vertically set on the main body of the adjustment part; one end of the left and right adjustment plates is rotatably connected with the main body of the adjustment part, and the other end of the left and right adjustment plates is respectively rotatably connected with the left and right half reflectors; the guide post The sliding thread is arranged at the bottom of the shell; the adjusting screw is axially rotatably connected with the bottom of the shell, the bottom end is an adjusting end, which is exposed from the bottom of the shell, and the upper end passes through the adjusting hole at the bottom of the shell, and is threadedly matched with the threaded hole. The lamp provided by the invention realizes the adjustment of the size of the light spot, and because the reflector is adjusted inside the lamp, the overall protection level of the lamp and the light efficiency of the entire lamp are not reduced.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a lamp with adjustable light spot size. Background technique [0002] Existing lamps, such as LED lamps, usually include a housing, a protective plate on the top of the housing, a light source (LED module) built into the housing, a lens, and a reflector (or reflector) around the light source. After the assembly of this type of lamp is completed, the light emitting angle is relatively fixed, and the irradiation spot is also fixed after installation, which is inconvenient to adjust later. In particular, LED high pole lights used in stadiums, airport aprons, etc. often have large glare, which adversely affects on-site personnel, and it is necessary to be able to adjust the size of the light spot during use. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is at least to provide a lamp capable of...
