Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, and particularly relates to an adjustable LED light strip. Background Art

[0002] LED light strips have shown great practical value in a variety of application scenarios due to their flexible installation methods, high energy efficiency, and good light uniformity; they are particularly suitable for places that require long-strip lighting, such as the shelf display areas in shopping malls. By embedding them in the ceiling or the edges of the shelves, they can provide soft and uniform lighting for the goods, enhancing the attractiveness of the goods.

[0003] Due to the complexity of the installation environment, LED light strips often face inconsistent heights. For example, in large commercial spaces or industrial factories, LED light strips may need to be installed according to the shelves, display racks, or ceiling structures at different heights, but the design of the light strips themselves often does not have a flexible adjustment mechanism.

[0004] In actual use, the position of light concentration is not convenient to adjust, resulting in the light not being able to directly focus on the expected target area. The problems of height difference and difficult adjustment of the light concentration position may affect the uniformity of the lighting effect and the lighting quality of the target area, and thus have an adverse impact on the visual experience or work efficiency.

[0005] Therefore, there is a need for an adjustable LED light strip to solve the above problems. Content of the Utility Model

[0024] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0025] Please refer to Figures 1-4, the present utility model provides a technical solution: an adjustable LED light strip, which includes a support assembly 1, a lighting assembly 2, and a light condensing and adjusting assembly 3. The support assembly 1 includes a support base 12, and the support base 12 is installed on both sides of the lighting assembly 2. Two groups of support rods 13 are fixed in the middle of the support bases 12 on both sides. The lighting assembly 2 includes an upper light strip 21 and a lower light strip 22. The upper light strip 21 and the lower light strip 22 are both movably installed on the outside of the support rods 13. A light condensing and adjusting assembly 3 is arranged on the left side of the upper light strip 21 and the lower light strip 22. The light condensing and adjusting assembly 3 includes an arc-shaped rack 31. Arc-shaped racks 31 are fixed on the opposite sides of the left sides of the upper light strip 21 and the lower light strip 22. A linear rack 32 is engaged between the two arc-shaped racks 31. A pull rod 33 is fixed at the rear end of the linear rack 32. A rotary thread 331 is provided at the rear side of the pull rod 33. An internal thread block 34 is rotatably installed on the outside of the rotary thread 331. The internal thread block 34 is movably installed at the rear end of the left support base 12;

[0026] During use, the support base 12 is the basic support structure of the entire LED light strip, installed on both sides of the lighting assembly 2 to provide a stable installation platform. The support rods 13 play the role of movably installing the upper light strip 21 and the lower light strip 22. The upper light strip 21 and the lower light strip 22 are the actual lighting elements responsible for emitting light. The arc-shaped rack 31 converts linear motion into the rotational tilting motion of the light strip by engaging with the linear rack 32. The movement of the linear rack 32 will drive the arc-shaped rack 31 to rotate, thereby driving the upper light strip 21 and the lower light strip 22 to change the angle. The rotary thread 331 is used to cooperate with the internal thread block 34 to achieve the linear motion of the pull rod 33. These parts work together, enabling the adjustable LED light strip to adjust the tilting angle and light condensing direction of the light strip according to actual needs, thereby achieving a more precise and flexible lighting effect.

[0027] An installation base 11 is installed on the outside of the support base 12 through installation bolts 111. The LED light strip can be fixed on various installation surfaces through the installation base 11.

[0028] A rubber sleeve 131 is arranged on the outside of the support rod 13. The function of the rubber sleeve 131 is to increase damping. By increasing damping, the rubber sleeve 131 can also improve the stability of the light strip system to a certain extent and reduce the shaking of the light strip caused by external factors.

[0029] A rear cover 23 is installed in the middle of the support bases 12 on both sides. The rear cover 23 is arranged at the rear side of the upper light strip 21 and the lower light strip 22. A reflective layer 231 is arranged on the inner side of the rear cover 23. The rear cover 23 plays a role of sealing and protecting. The function of the reflective layer 231 is to reflect light. When the light emitted by the LED light strip irradiates on the reflective layer 231, the reflective layer 231 will reflect part of the light back to the front or a specific direction, thereby enhancing the lighting effect.

[0030] A front baffle 24 is installed in the middle of the two-sided support base 12. The front baffle 24 is arranged on the front side of the upper light bar 21 and the lower light bar 22. The front baffle 24 is made of a transparent material and can effectively block external impurities such as dust, insects, and splashes from entering the interior of the light bar.

[0031] A chute 121 is provided on the right side of the left support base 12. A slider 321 is fixed to the left side of the linear rack 32. The slider 321 is slidably installed inside the chute 121. Since the slider 321 slides in the chute 121, it can ensure that the linear rack 32 always maintains a horizontal position during movement.

[0032] Multiple grooves 341 are provided on the outer side of the internally threaded block 34. The purpose of the design of the grooves 341 is to increase the friction between the internally threaded block 34 and the outside.

[0033] As an embodiment of the present utility model: when adjusting the adjustable LED light bar, first, the internally threaded block 34 rotates on the outside of the rotating thread 331 to drive the pull rod 33 to move horizontally. The movement of the pull rod 33 drives the linear rack 32 to slide horizontally in the chute 121, and then through the meshing action, the arc rack 31 rotates to adjust the inclination angles of the upper light bar 21 and the lower light bar 22, and rotates until the required illumination angle is reached; thus, the adjustment of the adjustable LED light bar is completed.

[0034] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0035] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
