Abstract

The invention discloses a down lamp with an adjustable irradiation range. The down lamp comprises a cylindrical mounting base; a limiting ring is arranged on the inner periphery of the lower edge of the mounting base; a mounting positioning ring is arranged on the periphery of the lower edge of the mounting base; mounting spring clamps are arranged on the two sides of the outer wall of the mounting base correspondingly; a guide pipe base is detachably arranged in the mounting base, an annular boss matched with the limiting ring is arranged on the outer wall of the guide pipe base, a mounting supporting ring is arranged on the inner periphery of the lower edge of the guide pipe base, a plurality of annular positioning grooves are formed in the inner wall of the guide pipe base from top to bottom, a lamp holder is movably arranged in the guide pipe base, and a lens, a reflector and a lamp panel are arranged in the lamp holder; a heat dissipation cover is detachably arranged on the lamp holder; the bottom edge of the heat dissipation cover presses the lower edge of the lens to fix the lens; a wire hole for a wire connected with the lamp panel to penetrate out is formed in the heat dissipation cover, an annular mounting groove is formed in the periphery of the heat dissipation cover, an elastic ring matched with the annular positioning grooves is embedded in the mounting groove, asemicircular pull ring is arranged on the lower surface of the lamp holder, and the two ends of the pull ring are in transition fit with mounting holes in the lamp holder.

Description

technical field [0001] The invention relates to a downlight, in particular to a downlight with an adjustable irradiation range. Background technique [0002] Downlights are widely used in modern decoration. Although some downlights can be rotated to adjust the irradiation angle, the irradiation range of existing downlights is fixed after installation. For some situations that need to adjust the irradiation range, such as the lighting required for museum exhibits, it is generally realized by an external adjustable bracket. However, this installation structure is relatively complicated, and the power supply lines and the like are exposed, which is not beautiful enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a downlight with an adjustable irradiation range. [0004] In order to solve the above technical problems, the technical solution adopted in the present invention is: a downlight with an adjustable ir...
