Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a rotating wall washer light fixture. Background Technology

[0002] Wall washer lights, a common architectural lighting fixture, are widely used in indoor and outdoor walls, landscapes, stages, and other scenarios to create a uniform and soft lighting effect. Traditional wall washer lights mostly use a fixed installation structure, and their illumination angle is limited after installation, making it difficult to flexibly adjust according to actual lighting needs. To achieve multi-angle lighting effects, some products have introduced a rotatable structure, but such structures often face technical challenges in power supply connections: if ordinary wires are used for direct connection, the wires are prone to tangling, pulling, or even breaking when the light fixture rotates, affecting lifespan and safety; if traditional rotating conductive structures such as slip rings are used, there are problems such as complex structure, high cost, unstable contact, and easy generation of electrical sparks. In addition, the design of single-sided support and power supply also has shortcomings in terms of mechanical stability and electrical reliability; once the connection fails, the entire light fixture will not function properly. Summary of the Invention

[0003] This invention addresses the problems of existing technologies by providing a rotating wall washer light fixture. When the light fixture body rotates around its axis, the conductive connector rotates synchronously within the movable cavity, while the elastic conductive needle maintains a tight sliding contact with its surface, achieving dynamic power supply. This invention enables the light fixture body to rotate freely 360° without interrupting power supply, meeting the needs of wall washer lights for multi-angle illumination. The support components of the support mechanism on both sides cooperate with the rotating conductive components to achieve support and conductive connection, improving overall mechanical stability and electrical redundancy, avoiding single-point failure, and eliminating the need for exposed wires, thus improving the product's aesthetics and safety.

The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0030] A rotating wall washer light fixture, such as Figures 1 to 10As shown, it includes a lamp body 30 and two support mechanisms 29. The lamp body 30 is located between the two support mechanisms 29. Each support mechanism 29 includes a support component and a rotary conductive component disposed at one end of the support component. The rotary conductive components on the two support mechanisms 29 are respectively connected to both ends of the lamp body 30. The rotary conductive component includes a support base 1 and a circuit board 2 installed in the support base 1. The support base 1 is provided with a movable cavity 3. A conductive connector 4 is rotatably disposed in the movable cavity 3. An elastic conductive pin 5 is installed on the circuit board 2. The upper end of the elastic conductive pin 5 protrudes into the movable cavity 3 and slides against the conductive connector 4. One end of the conductive connector 4 is located in the movable cavity 3, and the other end of the conductive connector 4 is used to connect to the lamp body 30. Specifically, the lamp body 30 of this invention is connected to the corresponding support mechanism 29 at both ends through two rotating conductive components. Each rotating conductive component has a rotatable conductive connector 4 inside, one end of which is electrically connected to the lamp body 30, and the other end is in sliding contact with the power circuit fixed on the circuit board 2 through an elastic conductive pin 5. When the lamp body 30 rotates around its axis, the conductive connector 4 rotates synchronously in the movable cavity 3, while the elastic conductive pin 5 always maintains a tight sliding contact with its surface, realizing dynamic power supply. This invention enables the lamp body 30 to rotate freely 360° without interrupting power supply, meeting the needs of wall washer lights for multi-angle illumination. The support components and rotating conductive components of the support mechanism 29 on both sides cooperate to achieve support and conductive connection, improve overall mechanical stability and electrical redundancy, avoid single-point failure, and eliminate the need for exposed wires, improving the product's aesthetics and safety.

[0031] In this embodiment, the upper end of the support base 1 is provided with a through hole 28 communicating with the movable cavity 3, and the elastic conductive needle 5 is movably inserted through the through hole 28. Specifically, the elastic conductive needle 5 extends upward from the circuit board 2, passes through the through hole 28 at the top of the support base 1 and enters the movable cavity 3, contacting the conductive connector 4; the through hole 28 provides a guiding and limiting channel for the elastic conductive needle 5, while allowing it to move slightly under pressure or thermal expansion and contraction, avoiding stress concentration; ensuring that the elastic conductive needle 5 is accurately aligned and contacts the conductive connector 4.

[0032] In this embodiment, the support assembly further includes a mounting base 20 and a support rod 21. The bottom of the support base 1 is provided with a mounting hole 22. One end of the support rod 21 is inserted into the mounting hole 22. A hollow screw 23 is also installed in the mounting hole 22. The hollow screw 23 passes through the mounting hole 22 and is screwed to one end of the support rod 21. The support rod 21 has a first wire-passing groove 24 extending through it along its length. A fixing bushing 25 is provided in the middle of the mounting base 20. The other end of the support rod 21 is screwed to the fixing bushing 25. The fixing bushing 25 has a second wire-passing groove 26 extending through it. The mounting base 20 also has a wire-passing hole 27 extending through it. The wire-passing hole 27 is correspondingly provided and communicates with the second wire-passing groove 26. Specifically, the upper end of the support pole 21 is inserted into the mounting hole 22 at the bottom of the support base 1 and locked in place by the hollow screw 23 to form a stable connection. The support pole 21 has a first wire-passing groove 24 inside, the fixing bushing 25 in the middle of the mounting base 20 has a second wire-passing groove 26, and the base also has a wire-passing hole 27. The three are connected to form a closed cable channel from the inside of the lamp to the external power supply. The power cable enters from the wire-passing hole 27, passes through the fixing bushing 25 and the support pole 21, and finally connects to the circuit board 2 inside the support base 1. This achieves fully concealed wiring, a clean appearance, no exposed cables, and enhances the industrial design. The cables are protected from pulling, wear, and aging, improving safety and service life. The hollow screw 23 serves both as a fixing function and as part of the cable channel, resulting in a highly integrated structure. Furthermore, the modular design facilitates transportation, installation, and maintenance.

[0033] In this embodiment, the mounting base 20 has locking holes on both sides. Specifically, with the above configuration, it can be connected to external structures such as ceilings, brackets, or workbenches via bolts to achieve hanging, wall-mounting, or table-mounting of the light fixture; providing multiple installation methods to adapt to different application scenarios and enhancing the product's versatility and adaptability.

The fastening structure allows for quick opening and closing without tools. The movable cavity 3 serves to prevent dust, moisture, and foreign object intrusion, protecting the internal conductive components. Furthermore, the detachable design of the protective cover 6 facilitates the inspection, cleaning, or replacement of easily damaged parts such as the elastic conductive pin 5 and the conductive connector 4. The fastening connection simplifies the assembly process and reduces manufacturing costs.

Preferably, the rotating conductive part 12 and the lamp connecting part 13 are integrally formed, resulting in strong structural stability.

Fixing holes 19 are provided through each of the four corners of the top shell 16, with the connection holes 18 and fixing holes 19 corresponding to each other. Specifically, the support base 1 is formed by combining the bottom shell 15 and the top shell 16 through the connection holes 18 and fixing holes 19 of the support blocks 17 at the corners, and connecting them with screws to form a whole. The internal space is used to install the circuit board 2 and other electronic components. The split design facilitates the installation and wiring of internal components, the four-corner fixing structure provides high rigidity and shock resistance, and the modular shell facilitates standardized production and subsequent maintenance.
