Description

Technical Field

[0001] This utility model belongs to the technical field of LED lighting devices, and in particular relates to a foldable multi-angle LED lighting device. Background Technology

[0002] LED lighting devices are lighting equipment that use light-emitting diodes as the light source. They have significant advantages such as high efficiency, energy saving, long life, and environmental protection without pollution. They can directly and efficiently convert electrical energy into light energy and are widely used in various lighting scenarios such as homes, businesses, industries, and outdoors. They are gradually replacing traditional lighting technologies and becoming the mainstream lighting solution. LED lighting devices for desktops can compensate for insufficient light intensity on the desktop when reading and writing, and reduce eye fatigue for users.

[0003] Currently, LED lighting devices commonly used for desktop lighting have limited lighting angles and ranges due to the design of the lamp arm structure. Most products only support the lamp head to tilt up and down or rotate horizontally on a single axis, and the lamp arm length is fixed with limited joint rotation angles. This results in a narrow illumination area during actual use. When users need to expand the lighting coverage or switch between high and low angle lighting, they are often forced to move the device because the lamp head cannot extend at multiple angles or the lamp arm length is insufficient. Frequent moving can easily cause the LED lighting device to be bumped and damaged, affecting its efficiency and making it unsuitable for use.

[0004] To address these issues, we provide a foldable multi-angle LED lighting device. Utility Model Content

[0005] The purpose of this invention is to provide a foldable multi-angle LED lighting device. By combining the multi-angle folding component and the illumination range adjustment component, the problem of the fixed lamp arm length and limited joint rotation angle of the existing LED lighting device, which leads to a narrow illumination area, is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a foldable multi-angle LED lighting device, comprising a base, a multi-angle folding assembly, and an illumination range adjustment assembly. A column is fixedly connected to the top of the base, and a stabilizing mechanism is provided on the rear side of the column. The multi-angle folding assembly includes a control shell, a positioning gear ring is fixedly connected to the left side of the control shell, and a rotating shaft is movably connected to the left side of the positioning gear ring. The left side of the rotating shaft is fixedly connected to the column. A first spring and a fixing gear ring are sequentially fitted onto the surface of the column from left to right. The illumination range adjustment assembly includes a sliding sleeve, both sides of which are fixedly connected to the inner wall of the control shell. A sliding rod is provided in the inner cavity of the sliding sleeve, a connecting frame is fixedly connected to the top of the sliding rod, an extension arm is fixedly connected to the top of the connecting frame, and a lamp assembly is fixedly connected to the front side of the extension arm.

[0008] The present invention is further configured such that the stabilizing mechanism includes a threaded sleeve, the front side of which is movably connected to the column, a screw threadedly connected to the inner cavity of the threaded sleeve, a suction cup movably connected to the bottom of the screw, and a knob fixedly connected to the top of the screw. The threaded sleeve facilitates the use of the screw, enabling it to move up and down smoothly. The screw controls the height of the suction cup, allowing it to adhere to the desktop, thus improving the stability of the entire lighting device. The knob facilitates the user's rotation of the screw.

[0009] The present invention is further configured such that the positioning mechanism includes a movable plate, a top rod is fixedly connected to the top of the movable plate, the top of the top rod penetrates the control shell and contacts the slide rod, and a second spring is fixedly connected to the bottom of the movable plate. The movable plate can prevent the top rod from disengaging from the inner cavity of the control shell, the top rod can squeeze the slide rod to prevent it from sliding, and the second spring can cooperate with the movable plate to control the top rod to always be in contact with the slide rod.

[0010] The present invention is further configured such that the front and rear sides of the movable plate are provided with sliding grooves, the inner cavity of the sliding grooves is slidably connected with sliding strips, and the opposite sides of the two sliding strips are fixedly connected to the inner wall of the control shell. The bottom of the sliding rod is provided with a groove for use with the top rod. The sliding grooves and sliding strips are used to improve the stability of the movable plate during movement. The groove can cooperate with the top rod to position the sliding rod and increase its anti-retraction effect.

[0011] The present invention is further configured such that a limiting groove is provided on the front side of the extension arm, and a limiting block is slidably connected to the inner cavity of the limiting groove. The front and rear sides of the limiting block are fixedly connected to the inner wall of the control shell.

The anti-slip rubber pad can increase the anti-slip effect of the base, and the slide rod slidably connected to the slide sleeve can make the connecting frame slide smoothly.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model uses a multi-angle folding component, a control shell and a positioning gear ring to cooperate with the rotating shaft to achieve horizontal rotation adjustment of the lamp assembly. The first spring pushes the fixed gear ring to engage with the positioning gear ring to lock the angle. With the support of the column, multiple levels of pitch angle adjustment can be performed to expand the projection range of the lamp assembly. The extension arm achieves stable extension through the cooperation of the limiting groove and the limiting block, solving the problem of narrow illumination area caused by the fixed length of the traditional lamp arm, reducing the risk of bumps caused by frequent movement of the device, and improving the efficiency of use.

[0017] 2. This utility model uses an illumination range adjustment component. The sliding rod slides within the sliding sleeve, causing the connecting frame and extension arm to extend and retract, adjusting the front and rear positions of the lamp assembly. In the positioning mechanism, the movable plate is locked in the extension length by inserting the top rod into the groove of the sliding rod. The second spring provides continuous clamping force to prevent retraction. Combined with the threaded sleeve and screw, the suction cup is adjusted to adhere to the table height. The knob controls the suction cup to enhance the stability of the base. The lamp assembly covers a larger illumination area through multi-stage extension and retraction, avoiding the problem of limited illumination range caused by insufficient joint rotation angle in traditional devices, and meeting the needs of switching between high and low angles.
