The following description contains two independent and complete technical schemes.

[0032] Embodiment 1: Horizontal rotating lamp

[0033] As shown in Figure 1, the present embodiment provides a horizontal rotating lamp. The lamp mainly includes a base 1, a transfer seat 2 and a light emitting component 3 from bottom to top. The base 1 is a cylindrical shell, and the side wall thereof can be provided with spring buckles (not shown in the figure) for easy embedding into the ceiling for installation. The light emitting component 3 (including light source, optical lens, heat sink, etc.) is fixedly installed on the transfer seat 2.

[0034] As shown in Figure 1, the present embodiment provides a horizontal rotating lamp. The lamp mainly includes a base 1, a transfer seat 2 and a light emitting component 3 from bottom to top. The base 1 is a cylindrical shell, and the side wall thereof can be provided with spring buckles (not shown in the figure) for easy embedding into the ceiling for installation. The light emitting component 3 (including light source, optical lens, heat sink, etc.) is fixedly installed on the transfer seat 2. Figures 1 to 3

[0035] ​​The core of the horizontal rotation function is the horizontal rotation mechanism 4. The mechanism includes a first fixed component 41 fixedly connected with the base 1 by screws or buckles, and a first rotating component 42 fixedly connected with the intermediate seat 2. The center of the first fixed component 41 is shaped or fixed with a first transmission gear ring 411. The outer circumferential surface of the first transmission gear ring 411 is integrally formed or tightly assembled with a radially outwardly extending sleeve 8. In the embodiment, the cross section of the sleeve 8 is preferably processed into an L shape.

[0036] The first rotating component 42 is fixedly connected with the intermediate seat 2. In the embodiment, the first rotating component 42 includes a first sleeve seat 421 and a first matching seat 422, which are fastened together by circumferentially distributed bolts and clamp the first transmission gear ring 411 on the first fixed component 41 in the accommodation space formed between the two. On the first sleeve seat 421, an annular flange 420 is formed inwardly extending. When assembled, the end of the annular flange 420 accurately extends into the corner space of the L-shaped sleeve 8. This makes the inner cylindrical surface of the annular flange 420 and the outer cylindrical surface of the vertical section of the sleeve 8 form a precise radial sliding fit, while the bottom end surface of the annular flange 420 and the upper surface of the horizontal section of the sleeve 8 form an axial limiting relationship. This guide structure is one of the key designs for the horizontal rotation lamp to achieve high radial stiffness and suppress light spot shaking.

[0037] In order to bear the weight of the intermediate seat 2 and the light emitting component 3, and provide extremely low resistance rotation, the present case sets up two groups of rolling pairs up and down. As shown in Figure 2 and Figure 3 The first rolling pair 5 is provided between the top surface of the first fixed component 41 and the bottom surface of the first sleeve seat 421. Specifically, it includes a plurality of first group of pits 51 processed upward on the bottom surface of the first sleeve seat 421, a first annular raceway 52 processed on the top surface of the first fixed component 41, and a plurality of first rolling bodies 53 arranged therebetween. The second rolling pair 6 is provided between the bottom surface of the first fixed component 41 and the top surface of the first matching seat 422. Specifically, it includes a second group of pits 61 processed upward on the bottom surface of the first fixed component 41, a second annular raceway 62 processed on the top surface of the first matching seat 422, and a plurality of second rolling bodies 63. All rolling bodies are preferably steel balls or ceramic balls. The two groups of rolling pairs jointly bear the axial load of the main part of the lamp, and efficiently convert sliding friction into rolling friction, so that the rotation resistance torque is extremely small and uniform.

[0038] The driving mechanism is the first drive mechanism 7. The first drive motor 71 is fixedly mounted on the side of the intermediate rotating base 2. After the output shaft of the first drive motor 71 is reduced in speed and amplified in torque by the first transmission assembly 72 (which may include multi-stage gear reduction), the first output gear 73 at the end of the drive rotates. Since the first output gear 73 meshes with the first transmission gear ring 411 on the fixed first fixed assembly 41, according to the gear transmission principle, when the first output gear 73 rotates under the drive of the motor, it will be subjected to a reaction force from the fixed gear ring. This reaction force drives the first drive motor 71 and the entire first rotating assembly 42, the intermediate rotating base 2 and the light-emitting component 3 to revolve around the center of the first transmission gear ring 411 (i.e., the vertical axis Z), thereby realizing the smooth and stable horizontal rotation of the light-emitting component 3 in the horizontal plane.

[0039] Example 2: Tilting Rotating Light Fixture

[0040] like Figures 4 to 6 As shown, this embodiment provides a tilting and rotating lamp. The lamp includes a base 1, a central pivot 2, and a light-emitting component 3. The base 1 is used for fixed installation. The light-emitting component 3 is a light-emitting unit. The central pivot 2 is the core feature of this solution, and its main body is machined with a mounting reference surface 210 that is tilted relative to the vertical center line Z of the lamp. The tilt angle α of this mounting reference surface 210 (the angle between its normal and the vertical direction) is preferably 40 degrees, but can also be adjusted within the range of 30 to 50 degrees as needed. This precisely machined physical plane has its normal direction uniquely and fixedly defined as the tilting rotation axis X of this solution.

[0041] A tilting and rotating mechanism 500 is connected between the central rotating base 2 and the light-emitting component 3 to achieve pitch rotation of the light-emitting component 3 around a fixed axis X. This mechanism includes a second fixing component 510 fixed to the mounting reference surface 210 by screws, and a second rotating component 520 fixedly connected to the housing of the light-emitting component 3. The second rotating component 520 is formed by fasteners connecting a second mating seat 522 and a second mating seat 523, with a second transmission gear ring 521 fixedly mounted on the second mating seat 522. During assembly, the second fixing component 510 is engaged and clamped between the second mating seat 522 and the second mating seat 523.

[0042] To achieve low-resistance rotation around the inclined axis X, a third rolling pair 600 and a fourth rolling pair 700 are respectively provided on the upper and lower sides of the second fixed assembly 510. For example... Figure 5 and Figure 6As shown, the third rolling pair 600 is located between the top surface of the second fixed assembly 510 and the bottom surface of the second fitting seat 522, and comprises a third set of pits 610 processed on the top surface of the second fixed assembly 510, a third annular raceway 620 processed on the bottom surface of the second fitting seat 522, and a plurality of third rolling bodies 630. The fourth rolling pair 700 is located between the bottom surface of the second fixed assembly 510 and the corresponding surface of the second fitting seat 523, and comprises a fourth set of pits 710 processed on the second fitting seat 523, a fourth annular raceway 720 processed on the bottom surface of the second fixed assembly 510, and a plurality of fourth rolling bodies 730. All the rolling bodies are preferably steel balls or ceramic balls. These rolling pairs ensure that the light-emitting component 3 and its connecting parts mainly generate rolling friction when rotating around the axis X, run smoothly and durably.

[0043] The driving motor 810 of the second driving mechanism 800 is fixedly installed on the transfer seat 2. The driving motor 810 drives the second output gear 830 to rotate through the second transmission assembly 820 (which can include a speed reduction gear). The second output gear 830 is directly engaged with the second transmission ring 521 installed on the moving part (the second rotating assembly 520). Therefore, when the driving motor 810 works, it directly drives the second rotating assembly 520 together with the light-emitting component 3 to perform rotational movement around the fixed inclined axis X defined by the normal line of the installation reference surface 210. The optical axis of the light-emitting component 3 rotates around the fixed inclined axis X, and the movement track of the light spot in space forms a conical surface, so as to efficiently and accurately cover the target area such as an inclined wall surface or an exhibit.

[0044] Combined application examples

[0045] In order to show the potential of the cooperative work of the two independent technical solutions of the utility model, an application example of integrating the horizontal rotation function and the inclined rotation function in the same lamp product is described below. It should be noted that the content of this part is intended to further explain and illustrate how the aforementioned independent technical solutions cooperate to achieve more complex functions.

[0046] In this integrated application example, the lamp comprises a base 1, a transfer seat 2 and a light-emitting component 3. The base 1 is used for fixed installation. Between the base 1 and the transfer seat 2, the horizontal rotation mechanism 4 as described in Embodiment One is arranged, which is used for driving the transfer seat 2 to rotate around the vertical axis Z. At the same time, the installation reference surface 210 with a fixed inclination is processed on the transfer seat 2, and the light-emitting component 3 is installed on the installation reference surface 210 through the inclined rotation mechanism 500 as described in Embodiment Two, so as to be able to rotate around the inclined axis X.

[0047] The working process embodies the cooperation of two independent mechanisms: when the first driving mechanism 7 of the horizontal rotating mechanism 4 works, the intermediate seat 2 and the inclined rotating mechanism 500 and the light-emitting component 3 carried thereon are driven as a whole to rotate horizontally around the vertical axis Z. When the second driving mechanism 800 of the inclined rotating mechanism 500 works, the light-emitting component 3 is independently driven to rotate around the fixed inclined axis X. By controlling the first driving mechanism 7 and the second driving mechanism 800, flexible orientation of the light-emitting component in space can be realized.

[0048] The examples in this part show that the horizontal rotating mechanism and the inclined rotating mechanism provided by the utility model are two independent solutions with high performance and modularity. They can be implemented independently or combined for application according to actual needs.

[0049] The above description is only the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
