Abstract

The invention discloses an LED projection lamp with an adjustable projection angle. The LED projection lamp comprises a shell with an opening formed in one side; an LED lamp arranged in the lengthening direction of the shell is mounted in the shell, and a over plate is fixedly connected with the opening of the shell in a sleeving mode; a storing groove arranged in the lengthening direction of theshell is formed in the side, away from the cover plate, of the shell, and a rotating shaft arranged in the lengthening direction of the storing groove is movably connected with the interior of the storing groove in a sleeving mode; an adjusting sleeve ring is fixedly connected with the outer ring of the rotating shaft in a sleeving mode; and a protective cover fixedly connected with the shell is mounted in the opening of the storing groove, two channels arranged in the lengthening direction of the protective cover are arranged on the side, away from the shell, of the protective cover, and thetwo channels are arranged along the protective cover symmetrically, and a fixed rod arranged in the lengthening direction of the channels is fixedly connected with the position between the inner sidewalls of the two sides of the two channels in a sleeving mode. The LED projection lamp is simple in structure and quick and convenient to operate, on the one hand, the position used for arranging thefixed plate on the projection corner can be adjusted, and the LED projection lamp is suitable for installation and fixation of different occasions; and on the other hand, the projection angle of the projection corner can be adjusted.

Description

technical field [0001] The invention relates to the technical field of floodlights, in particular to an LED floodlight with an adjustable projection angle. Background technique [0002] Floodlights are lamps that specify that the illuminance on the illuminated surface is higher than that of the surrounding environment. Also known as spotlight. Generally, it is capable of aiming in any direction and has a structure that is not affected by climatic conditions. It is mainly used for large-area operation sites, mines, building outlines, stadiums, overpasses, monuments, parks and flower beds, etc. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights. The output beam angle of floodlights can be wide or narrow, and the range of variation is between 0° and 180°. Among them, those with extremely narrow beams are called searchlights. Traditional floodlights have a fixed projection direction and are inconvenient to adjust. Therefore, it is ...
