In the above technical solution, the wall base is used to fix the LED lamp arm on the wall or other supporting devices, the lamp base is used to fix the LED light source, and the second lamp arm can rotate around the first lamp arm in the horizontal direction through the rotating positioning member. 360° rotation is used to adjust the irradiation position of the LED light source installed on the lamp holder; at the same time, the horizontal angle of the first lamp arm relative to the wall seat can be adjusted through the rotation of the longitudinal connecting piece relative to the horizontal connecting piece, thereby expanding the position of the LED light source range of adjustment.

Preferably, the rotary positioning member includes an upper end, a lower end and a movable link, the upper end is fixed on the upper part of the movable link, and the lower part of the movable link can be inserted into the lower end 360° around the lower end Inside the head, the first lamp arm is fixed on one side of the lower end, and the second lamp arm is fixed on one side of the upper end. Through the relative rotation of the upper end and the lower end, the rotation of the second lamp arm relative to the first lamp arm can be realized, thereby driving the rotation of the irradiation position of the LED light source.

Preferably, one side of the lamp holder is provided with fixing bolts for fixing the LED light source. The LED light source can be fixed on the side of the lamp holder through fixing bolts.

Preferably, a rocker switch is provided outside the bottom of the lamp holder to control the rotation of the lamp holder. The rocker switch is used to control the rotation of the lamp holder relative to the second lamp arm. When the lamp holder needs to be rotated, turn the rocker switch to the "on" position, and then adjust the rotation angle of the lamp holder. After adjustment, turn the rocker switch Rotate to the "off" position, lock the lamp holder, and prevent the angle of the lamp holder from changing at will. By changing the angle of the lamp holder, the irradiation angle of the LED light source fixed on the lamp holder can be driven to change, thereby realizing the adjustment of the irradiation angle of the LED light source.

The beneficial effects of the LED lamp arm provided by the utility model are: 1) the structure of the LED lamp arm is simple, and the function of adjusting the irradiation position of the LED light source can be realized through the relative rotation of the second lamp arm and the first lamp arm; 2) the LED lamp arm The LED lamp arm can adjust the irradiation angle of the LED light source through the rotation of the lamp holder relative to the second lamp arm; 3) The LED lamp arm can adjust the first lamp arm through the rotation of the longitudinal connector relative to the horizontal connector Relative to the horizontal angle of the wall seat, thereby expanding the range of position adjustment of the LED light source.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. All other embodiments obtained by ordinary persons in the art without creative efforts belong to the protection scope of the present utility model.

Embodiment: an LED lamp arm.

Referring to FIG. 1 , an LED lamp arm includes: a wall seat 100; two horizontal connectors 110 installed on one side of the wall seat 100 and distributed side by side up and down; The longitudinal connecting member 120 rotating on the transverse connecting member 110; the first lamp arm 200 fixed in the middle of the longitudinal connecting member 120; the rotating positioning member 210 installed at one end of the first lamp arm 200; a lamp arm 300 ; and a lamp holder 400 fixed at one end of the second lamp arm 300 .

In the above technical solution, the wall base 100 is used to fix the LED lamp arm on the wall or other supporting devices, the lamp base 400 is used to fix the LED light source, and the second lamp arm 300 can rotate around the first lamp arm 210 200 rotates 360° in the horizontal direction to adjust the irradiation position of the LED light source installed on the lamp holder 400; at the same time, the first lamp arm 200 can be adjusted relative to the wall seat through the rotation of the longitudinal connecting member 120 relative to the horizontal connecting member 110 The horizontal angle of 100°, thus expanding the range of LED light source position adjustment.
