Description

Technical Field

[0001] The present disclosure relates to the technical field of lamps, and in particular to an LED lamp. Background Art

[0002] At present, conventional downlights are all rotated vertically on the centroid axis of the lamp. Due to the limitation of the structural space, they can only rotate about 25° in the vertical direction. Through the principle of the ball centroid, 30° vertical rotation can be achieved. In the horizontal direction, the limit convex points of the rotating lamp body contact the limit convex points of the barrel body to control the lamp body to rotate 350°. This will have a little defect. After installation and fixation, there is a 10° horizontal direction that cannot be adjusted in place, which will cause the customer to reinstall the lamp. There is no limit in the horizontal direction, and unlimited rotation will cause customers to not know the rotation state and degree of the internal wires, which may cause excessive rotation and cause the hidden danger of the internal electronic wires being torn off.

The edge of the cover 38 extends to form the limiting portion 32, so the limiting portion 32 and the cover 38 can be integrally formed.

[0033] In one embodiment, the LED lamp 100 further includes a power supply 60 and a wiring terminal 70, the power supply 60 and the wiring terminal 70 are arranged in the barrel 10, and the other end of the power line 50 is electrically connected to the power supply 60 through the wiring terminal 70. The power supply 60 and the wiring terminal 70 are built in the barrel 10, which can adapt to a variety of application scenarios.

[0034] In one embodiment, the rotating bracket 23 is provided with a cylinder 26 away from the center of the fixed bracket 24, the cylinder 26 is connected to the wire passage 25, and the power cord 50 is also passed through the cylinder 26. The cylinder 26 can store the power cord 50, so that the power cord 50 is arranged neatly.

[0035] In one embodiment, the bracket assembly 20 also includes a limiting piece 27, one end of which is hingedly arranged on a side of the rotating bracket 23 away from the fixed bracket 24, and one end of the limiting piece 27 is located at the non-rotation center of the rotating bracket 23; an end of the side of the rotating bracket 23 away from the fixed bracket 24 is also provided with an arc-shaped limiting groove 232, the arc-shaped limiting groove 232 is arranged along the circumference of the rotating bracket 23, and the limiting piece 27 is penetrated into the arc-shaped limiting groove 232; a limiting rib 14 is also provided on the inner wall of the cylinder 10, and the other end of the limiting piece 27 extends to the inner wall of the cylinder 10, after the rotating bracket 23 rotates to the first position relative to the cylinder 10, the other end of the limiting piece 27 can abut against the limiting rib 14, and after the rotating bracket 23 continues to rotate to the second position relative to the cylinder 10, the other end of the limiting piece 27 can abut against the groove wall of the arc-shaped limiting groove 232.

[0036] When the rotating bracket 23 rotates relative to the cylinder 10, the limiting piece 27, the fixed bracket 24, the LED lamp assembly 30, etc. all rotate synchronously relative to the cylinder 10. There are two first positions and two second positions, that is, there is a first position and a second position when the rotating bracket 23 rotates forward, and there is also a first position and a second position when the rotating bracket 23 rotates reversely. When the rotating bracket 23 rotates to the first position, one side of the limiting rib 14 on the inner wall of the cylinder 10 can block the other end of the limiting piece 27. Therefore, when the rotating bracket 23 continues to rotate, the other end of the limiting piece 27 rotates relative to one end (hinged end) of the limiting piece 27. When the rotating bracket 23 rotates to the second position, the other end of the limiting piece 27 abuts against one end of the limiting groove. At this time, the rotating bracket 23 cannot continue to rotate relative to the cylinder 10. Similarly, when the rotating bracket 23 rotates in the opposite direction, after the rotating bracket 23 rotates to another first position, the other side of the limiting rib 14 on the inner wall of the cylinder 10 can block the other end of the limiting plate 27. Therefore, when the rotating bracket 23 continues to rotate, the other end of the limiting plate 27 rotates relative to one end (the hinged end) of the limiting plate 27. When the rotating bracket 23 rotates to another second position, the other end of the limiting plate 27 abuts against the other end of the limiting groove. At this time, the rotating bracket 23 cannot continue to rotate relative to the cylinder 10. By setting it in this way, the rotating bracket 23 can be limited to rotate 360° relative to the cylinder 10 and cannot continue to rotate. In this way, the demand for 360° adjustment can be met, and the phenomenon of twisted wires in the power cord 50 can be avoided.
