[0033] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] like Figure 1 and Figure 2 As shown, the reversible array spotlight according to an embodiment of the present invention includes a sliding base 100, a lamp body 200, a positioning mechanism, and an auxiliary fixing mechanism. The sliding base 100 is an elongated structure and is slidably mounted on the track assembly. The lamp body 200 is also an elongated structure and is mounted to the sliding base 100 via a rotating shaft mechanism. The lamp body 200 can rotate around the rotating shaft mechanism to a position where the length direction of the lamp body 200 intersects with the length direction of the sliding base 100. The positioning mechanism can position the lamp body 200 at the position where it rotates around the rotating shaft mechanism. The auxiliary fixing mechanism can fix the lamp body 200 to the sliding base 100 and make the length direction of the lamp body 200 and the length direction of the sliding base 100 are in the same direction.

[0036] The rotating shaft mechanism allows the lamp body 200 to rotate to a position where the length direction of the lamp body 200 intersects with the length direction of the sliding base 100. The positioning mechanism is used to position the lamp body 200 and the sliding base 100, thereby adjusting the illumination area. The auxiliary fixing mechanism ensures that the lamp body 200 and the sliding base 100 are aligned, facilitating the fixed use of the array spotlight.

[0037] Specifically, the reversible array spotlight can be applied to vertical or horizontal track assemblies. When the track assembly is horizontal, the lamp body 200 can be rotated horizontally to the set lighting position and positioned by the positioning mechanism, making it convenient and flexible to use. Since the lamp body 200 rotates in the horizontal plane, its stability and reliability are high. When the track assembly is vertical, the lamp body 200 can rotate in the vertical plane and be positioned by the positioning mechanism. Alternatively, an auxiliary fixing mechanism can be used to keep the lamp body 200 and the sliding base 100 in the same direction (i.e., the lamp body 200 is vertical), which facilitates the fixed use of the lamp body 200 and reduces the possibility of the lamp body 200 accidentally rotating out of the track assembly, thus improving safety and reliability.

[0038] It should be noted that, since both the lamp body 200 and the sliding base 100 are elongated structures, the positioning mechanism has limited placement space. In order to facilitate the rotation of the lamp body 200, the limiting resistance generated by the positioning mechanism is not large. When the track assembly is a horizontal track assembly, it is generally suspended at a high position, and the gravity is also concentrated at the center position. Therefore, the stability and safety of the lamp body 200 after it is horizontally rotated to the set lighting position and positioned by the positioning mechanism are good. When the track assembly is a vertical track assembly, the lamp body 200 has a lower sliding position, so it is easier to be accidentally touched and deviated, or to be deviated during transportation. In this utility model, the lamp body 200 and the sliding base 100 can be kept in the same direction (i.e., the lamp body 200 is vertical, i.e., roughly overlapping) by the auxiliary fixing mechanism, reducing the possibility of the lamp body 200 accidentally rotating out of the track assembly.

[0039] In some embodiments of this utility model, the rotating shaft mechanism connects the middle part of the lamp body 200 and the middle part of the sliding base 100. The auxiliary fixing mechanism is a magnetic attraction mechanism, which is located at the end of the lamp body 200 and the end of the sliding base 100. The magnetic attraction mechanism can magnetically fix the lamp body 200 to the sliding base 100, so that the length direction of the lamp body 200 is in the same direction as the length direction of the sliding base 100. When a large external force is applied, the magnetic attraction state of the magnetic attraction mechanism can be released, which facilitates the adjustment of the illumination area of ​​the lamp body 200.

[0040] like Figure 3 , Figure 4 As shown, in some embodiments of this utility model, the magnetic attraction mechanism includes a first magnetic attraction member 410 disposed at both ends of the lamp body 200 and a second magnetic attraction member 420 disposed at both ends of the sliding base 100. The first magnetic attraction member 410 and the second magnetic attraction member 420 are distributed correspondingly. The magnetic attraction between the first magnetic attraction member 410 and the second magnetic attraction member 420 is used to position the lamp body 200 in the same direction as the sliding base 100.

[0041] It is understood that in some embodiments of this utility model, the first magnetic suction member 410 may be provided only at one end of the lamp body 200, and the second magnetic suction member 420 may be provided at one end of the sliding base 100. That is, the effect of assisting in fixing the lamp body 200 can also be achieved by magnetic positioning at one end.

[0042] In some embodiments of this utility model, both the first magnetic attractor 410 and the second magnetic attractor 420 may be permanent magnets, or one of them may be a permanent magnet and the other may be a magnetic attractor made of magnetic materials (such as iron, nickel, etc.).

[0043] It is conceivable that in some embodiments of this utility model, the auxiliary fixing mechanism may also be a pin mechanism, a locking mechanism, etc., which will not be described in detail here.

[0044] like Figures 3 to 5 As shown, in some embodiments of this utility model, the positioning mechanism includes at least one ball bearing assembly 300 disposed on the lamp body 200. The ball bearing assembly 300 is offset from the axis of the rotating shaft mechanism. The sliding base 100 is circumferentially provided with at least two ball bearing holes 301 spaced apart. The position of the ball bearing hole 301 corresponds to the trajectory of the ball bearing assembly 300 rotating around the rotating shaft mechanism, so that when the lamp body 200 rotates around the rotating shaft mechanism to the position corresponding to the ball bearing assembly 300 and the ball bearing hole 301, the ball of the ball bearing assembly 300 can be inserted into the ball bearing hole 301 to achieve the positioning effect.

[0045] Specifically, the ball bearing assembly 300 is configured in two sets, symmetrically distributed on both sides of the axis of the rotating shaft mechanism to improve the stability of positioning. The ball bearing hole 301 is configured in eight pieces and evenly distributed in a ring to meet the adjustment requirements of the lamp body 200 in four directions.

[0046] Of course, in the specific implementation process, the ball assembly 300 can be configured as one or more sets, and the ball hole 301 can be configured in multiple ways according to the positioning needs, which will not be described in detail here.

[0047] In some embodiments of this utility model, the ball assembly 300 can also be called an elastic universal ball mechanism. The ball is set inside the cylinder by a spring. The ball part protrudes outward. When the ball is pressed, it can overcome the elastic force of the spring and move into the cylinder, which facilitates the relative movement of the sliding base 100 that abuts against the ball. When the sliding base 100 moves relative to the ball assembly 300 at the position corresponding to the ball hole 301, the ball of the ball assembly 300 can be inserted into the ball hole 301 to achieve the positioning effect.

[0048] It is understood that in some embodiments of this utility model, the positioning mechanism may also be a toothed disc mating mechanism, such as a toothed disc (such as a plastic toothed disc) being provided between the sliding base 100 and the lamp body 200, and positioning is achieved through the mating of the teeth.

[0049] like Figures 3 to 5 As shown, in some embodiments of this utility model, the rotating shaft mechanism includes a shaft pin 500, which includes a head 510, an optical axis portion 520, and a threaded portion 530 from top to bottom. The lamp body 200 is provided with a threaded hole 531 corresponding to the threaded portion 530. The sliding base 100 is provided with a mounting portion 101, which is provided with a shaft hole 521 corresponding to the optical axis portion 520. The threaded portion 530 passes through the shaft hole 521 and connects to the threaded hole 531. The mounting portion 101 is limited between the head 510 and the lamp body 200, and the optical axis portion 520 and the shaft hole 521 are rotatably engaged, so that the lamp body 200 can rotate around the optical axis portion 520, thereby realizing the connection and rotation of the lamp body 200 and the sliding base 100.

[0050] like Figure 3 As shown, in some embodiments of this utility model, the outer diameter of the optical axis portion 520 is larger than the outer diameter of the threaded portion 530, so as to form a stepped surface at the junction of the optical axis portion 520 and the threaded portion 530. When the threaded portion 530 is screwed into the threaded hole 531, the stepped surface presses against the lamp body 200, thereby better securing the shaft pin 500.

[0051] In some embodiments of this utility model, the mounting part 101 is a boss structure that is higher than the base plate 110 of the sliding base 100, that is, the mounting part 101 is thicker, which can improve the stability and reliability of the rotating structure.

[0052] like Figure 5 As shown, in some embodiments of this utility model, a friction plate 540 is provided between the head 510 and the mounting part 101; a friction plate 540 is provided between the sliding base 100 and the lamp body 200. The friction plate 540 can increase the frictional resistance, so that there is a certain rotational resistance between the lamp body 200 and the sliding base 100, which facilitates the positioning of the lamp body 200 and reduces the occurrence of the lamp body 200 becoming loose.

[0053] It is understood that in some embodiments of this utility model, a friction plate 540 may be provided only between the head 510 and the mounting part 101, or only between the sliding base 100 and the lamp body 200, which can also achieve the function of increasing friction.

[0054] In some embodiments of this utility model, the friction plate 540 may be a resin friction plate, a ceramic friction plate, a carbon fiber friction plate, etc. The friction plate 540 has a circular structure so that the shaft pin 500 can pass through for positioning.

[0055] like Figure 5As shown, in some embodiments of this utility model, the shaft pin 500 is provided with a through hole 501 extending along its length and penetrating the upper and lower ends. The wires of the lamp body 200 can pass through the through hole 501 into the sliding base 100 to realize the electrical connection between the sliding base 100 and the lamp body 200.

[0056] It is understood that in some embodiments of this utility model, the rotating shaft mechanism may also be an optical shaft, with both ends of the optical shaft limited to the lamp body 200 and the sliding base 100 respectively, and the lamp body 200 and the sliding base 100 may also rotate relative to each other.

[0057] like Figure 6 As shown, in some embodiments of this utility model, the lamp body 200 is provided with a plurality of independent light source components that are spaced apart along its length. The light source components include LED chips 210 disposed on the substrate 211 and optical components 220 corresponding to the LED chips 210. The light source components are all independently configured, which can meet different light effect requirements, such as cross illumination, reverse illumination, etc., and have high flexibility in use.

[0058] like Figure 7 As shown, in some embodiments of this utility model, the optical component 220 includes a lens 221 and a light-emitting tube 222. The LED chip 210, lens 221 and light-emitting tube 222 are distributed from top to bottom. The inner wall of the light-emitting tube 222 is provided with a reflective surface 223. The lens 221 controls the state of light emission (such as focused light, diffused light, parallel light, etc.). The light-emitting tube 222 is used to control the direction of light emission (such as direct light, oblique light, etc.), so that the array spotlight has a variety of illumination effects.

[0059] In some embodiments of this utility model, the lower end of the light-emitting tube 222 has a tapered structure to improve the brightness of the emitted light.

[0060] like Figure 5 , Figure 6 , Figure 7 As shown, in some embodiments of this utility model, the lamp body 200 includes an upper housing 230 and a lower housing 240 connected by a fastening mechanism. Multiple independent cavities corresponding to the light source components are formed between the upper housing 230 and the lower housing 240. The optical component 220 is installed in the independent cavity. The substrate 211 is fixed to the upper housing 230. When the upper housing 230 and the lower housing 240 are assembled, the optical component 220 can be positioned in the independent cavity and correspond to the LED chip 210.

[0061] like Figure 7 As shown, in some embodiments of this utility model, the lens 221 is fixed to the lens holder 224 by a snap-fit ​​structure to better protect the lens 221.

[0062] Of course, this invention is not limited to the above-described embodiments.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
