Description

Technical Field

[0001] The utility model belongs to the field of LED lighting, and particularly relates to an adjustable LED lighting fixture. Background Art

[0002] In the current lighting application field, especially in courtyard and construction site areas, LED lighting fixtures are widely adopted due to their high energy efficiency, long lifespan, and environmental protection characteristics. These fixtures use LEDs (light-emitting diodes) as light sources. Compared with traditional lighting technologies, LEDs can provide a light conversion efficiency of up to 80% - 90%, significantly reducing energy consumption and maintenance costs. However, with the popularization of such lighting solutions, some specific application challenges have gradually emerged.

[0003] Specifically, the courtyard and construction site environments pose special requirements for the installation of LED lighting fixtures. Generally, to ensure a wide lighting range, uniform illumination, and avoid direct glare to personnel, the fixtures need to be installed at a relatively high position. For example, indoor fixtures should be no less than 2.4 meters above the ground, and outdoor fixtures need to reach 3 meters or more. Although this height setting meets the lighting requirements, when the fixtures malfunction or need to be replaced, it brings operational inconveniences. Professional equipment and personnel are often required for high-altitude operations, increasing the maintenance difficulty and cost.

[0004] Another technical limitation is that most existing LED fixtures are designed with a fixed installation angle and cannot be adjusted according to changes in the actual application scenario or seasonal light requirements. This means that once the fixture is installed, its lighting direction and coverage area are fixed, and it may not always achieve the optimal lighting effect in a dynamically changing environment, affecting the user experience and energy efficiency.

[0005] Based on this, the utility model proposes an adjustable LED lighting fixture. Summary of the Utility Model

[0037] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will detail the present application with reference to the drawings and embodiments.

[0038] As Figures 1-6 , referring to Figure 1 , the present utility model provides an adjustable LED lighting fixture, including a bracket 1, a lifting mechanism 2, and a rotating mechanism 3;

[0039] The bracket 1 is fixed to the frame. The rotating mechanism 3 is installed on the bracket 1. The lifting mechanism 2 is installed outside the rotating mechanism 3. The lifting mechanism 2 is connected to the LED lamp 4. The rotating mechanism 3 is used to drive the lifting mechanism 2 and the LED lamp 4 to rotate, and the lifting mechanism 2 is used to drive the LED lamp 4 to move up and down.

[0040] Among them, the frame can be the ground or any fixed plane. When the frame is the ground, the bracket 1 can be installed on the ground through ground anchor nails.

[0041] As a further explanation of the present utility model, referring to Figure 1 , the rotating mechanism 3 includes a first rotating motor 31 and a first rotating shaft 32;

[0042] The first rotary motor 31 is fixed to the bracket 1. The output shaft of the first rotary motor 31 passes through the bracket 1 and is coaxially fixed to the first rotating shaft 32. A lifting mechanism 2 is installed outside the first rotating shaft 32.

[0043] When the present utility model is in use, the first rotary motor 31 rotates to drive the first rotating shaft 32 to rotate. The first rotating shaft 32 drives the lifting mechanism 2 to rotate, and the lifting mechanism 2 drives the LED lamp 4 to rotate.

[0044] Among them, the first rotary motor 31 has a self-locking function.

[0045] As a further explanation of the present utility model, refer to Figure 1 and Figure 2 , the lifting mechanism 2 includes a second rotary motor 21, a first gear 22 and a sleeve 23;

[0046] The second rotary motor 21 is fixed to the bracket 1. The output shaft of the second rotary motor 21 is coaxially fixed to the first gear 22. The first gear 22 meshes with the annular teeth formed on the outer surface of the sleeve 23. The sleeve 23 is key-connected to the first rotating shaft 32, and the sleeve 23 is connected to the LED lamp 4.

[0047] When the present utility model is in use, the second rotary motor 21 rotates to drive the first gear 22 to rotate. The first gear 22 drives the sleeve 23 to move up and down, and the sleeve 23 drives the LED lamp 4 to move up and down;

[0048] Combined with the rotating mechanism 3, the first rotating shaft 32 rotates and drives the sleeve 23 to rotate through the key connection structure. Therefore, the sleeve 23 can rotate and can move up and down, so that the LED lamp 4 can rotate and move up and down.

[0049] Among them, the second rotary motor 21 has a self-locking function.

[0050] As a further explanation of the present utility model, a plurality of groups of the annular teeth are uniformly formed along the axial direction of the sleeve 23.

[0051] As a further explanation of the present utility model, the sleeve 23 is connected to the LED lamp 4, and the specific connection method includes:

[0052] The outer circumferential surface of the sleeve 23 is fixed to the LED lamp 4.

[0053] As a further explanation of the present utility model, refer to Figure 2 , Figure 3 and Figure 6 , another deformation of the connection between the sleeve 23 and the LED lamp 4 is:

[0054] The LED lamp 4 includes a first connecting plate 41, a second connecting plate 42 and a third connecting plate 43;

[0055] The middle of the first connecting plate 41 is fixed to the sleeve 23. One end of the first connecting plate 41 is connected to the first hinge shaft 44 by bearings. The first hinge shaft 44 is fixed to the second connecting plate 42. The other end of the first connecting plate 41 is connected to the second hinge shaft 45 by bearings. The second hinge shaft 45 is fixed to the third connecting plate 43;

[0056] A first chute 46 is formed in the second connecting plate 42. A first slider 47 capable of moving along it is installed in the first chute 46. One end of the first slider 47 is hinged to one end of a first connecting rod 48. The other end of the first connecting rod 48 is hinged to an annular slider 49. The annular slider 49 is arranged in an annular groove 50 and rotates along it. The annular groove 50 is formed in the bracket 1;

[0057] The first hinge shaft 44 is coaxially fixed to the second gear 51. The second gear 51 meshes with the third gear 52. The third gear 52 is coaxially fixed to the second hinge shaft 45.

[0058] When the present utility model is in use, when the sleeve 23 moves upward, it drives the first connecting plate 41 to move upward. The first connecting plate 41 drives the second connecting plate 42 and the third connecting plate 43 to move upward. The second connecting plate 42 is connected to the first slider 47 through the first chute 46. Therefore, when the second connecting plate 42 moves upward, it will also swing clockwise along the axis direction of the first hinge shaft 44, making the included angle between it and the first connecting plate 41 larger. At this time, the first hinge shaft 44 will also rotate together with the second connecting plate 42. The first hinge shaft 44 drives the second gear 51 to rotate. The second gear 51 drives the third gear 52 to rotate counterclockwise. The third gear 52 drives the second hinge shaft 45 and the third connecting plate 43 to rotate counterclockwise, so that the swing angle of the lampshade of the LED lamp 4 becomes larger. At this time, the covering range of the lamp becomes larger.

[0059] When the sleeve 23 rotates, it drives the first connecting plate 41, the second connecting plate 42, the third connecting plate 43, the first slider 47, the first connecting rod 48, the annular slider 49, the first hinge shaft 44, the second hinge shaft 45, the second gear 51 and the third gear 52 to rotate together.

[0060] Wherein, the first connecting rod 48 can be a telescopic rod. The first connecting rod 48 can be hinged to the annular slider 49 or directly fixed.

[0061] Wherein, the middle part of the first connecting plate 41 is fixed to the sleeve 23 through a link with an adjustable angle, and the irradiation angle of the LED lamp 4 in the vertical direction is realized through the link with an adjustable angle.

[0062] Wherein, those skilled in the art can set the number of the annular teeth and the length of the second connecting plate 42 through a finite number of experiments, so that when the sleeve 23 rises and falls to the limit positions, the first slider 47 is always arranged in the first chute 46.

[0063] As a further explanation of the present utility model, see Figure 3 , the first slider 47 is a dovetail slider, and the first chute 46 is a dovetail chute matching the shape of the first slider 47.

[0064] As a further explanation of the present utility model, see Figure 3 , the annular slider 49 is an annular dovetail slider, and the annular groove 50 is a dovetail annular groove matching the shape of the annular slider 49.

[0065] As a further explanation of the present utility model, see Figure 4 and Figure 5 , both side surfaces of the first connecting plate 41, the second connecting plate 42 and the third connecting plate 43 are fixed to the reflective cloth 6.

[0066] The light source is arranged in the space surrounded by the first connecting plate 41, the second connecting plate 42, the third connecting plate 43 and the reflective cloth 6. The length of the reflective cloth 6 can meet the requirement that when the second connecting plate 42 and the third connecting plate 43 swing, a closed space can still be formed with the first connecting plate 41, the second connecting plate 42 and the third connecting plate 43, without affecting the reflection of light.

[0067] Wherein, the inner surfaces of the first connecting plate 41, the second connecting plate 42 and the third connecting plate 43 are made of materials with a reflective function.

[0068] As a further explanation of the present utility model, see Figure 3 , the centers of the annular slider 49 and the annular groove 50 coincide with the center of the sleeve 23.
