Abstract

The invention relates to a lamp capable of adjusting the light spot size. A reflection cover of the lamp comprises a left half reflection cover and a right half reflection cover which are rotationallyconnected with a shell of the lamp, the lamp comprises adjusting plates and a center adjusting part, the adjusting plates comprise the left adjusting plate and the right adjusting plate, the center adjusting part comprises an adjusting part main body, a guide column, a thread hole vertically formed in the adjusting part main body and an adjusting screw, one ends of the left and right adjusting plates are rotationally connected with the adjusting part main body, the other ends of the left and right adjusting plates are rotationally connected with the left and right half reflection covers, theguide column is arranged at the bottom of the shell in a sliding penetrating mode, the adjusting screw and the bottom of the shell are axially and rotationally connected, the bottom end is used as theadjusting end and exposed out of the bottom of the shell, and the upper end penetrates through an adjusting hole in the bottom of the shell to be in thread fit with the thread hole. According to thelamp, the light spot size is adjusted, and since the reflection cover is adjusted inside the lamp, the whole protection level and light effect of the whole 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...
