Technical Field
[0001] This application relates to the technical field of lighting fixtures. More specifically, it relates to a lighting fixture that can achieve automatic swinging. Background Art
[0002] In the design of lighting fixtures, the automatic adjustment of the irradiation angle of the light source has received increasing attention. This need mainly stems from improving the lighting effect, optimizing space utilization, and enhancing user comfort. Traditional lighting fixtures usually have a fixed light source position and cannot be flexibly adjusted to meet different lighting requirements.
[0003] Currently, there are lighting fixtures that can be manually adjusted in their swinging directions. However, manual adjustment has the problems of inconvenience in adjustment and high labor intensity. For example, stage lighting fixtures are usually installed at a relatively high position, and manual adjustment is rather inconvenient. Therefore, it is necessary to propose a lighting fixture that can automatically adjust its swinging direction to achieve changes in the irradiation angle of the light source. Summary of the Utility Model
[0004] In order to solve the problems of inconvenience in adjustment and high labor intensity in manually adjusting the swinging direction of the lighting fixture to achieve changes in the angle and direction of the light source, this application provides a lighting fixture that can achieve automatic swinging.

The intermediate rotating shell is rotatably connected to the bottom shell, the light source mounting shell is rotatably connected to the intermediate rotating shell, the extension line of the rotation center of the light source mounting shell is perpendicular to the extension line of the rotation center of the intermediate rotating shell. The first driving component is used to drive the intermediate rotating shell to rotate, the second driving component is used to drive the light source mounting shell to rotate, and a light-emitting component is installed on the light source mounting shell.

The intermediate rotating shell is rotatably connected to the bottom shell, the light source mounting shell is rotatably connected to the intermediate rotating shell, and the extension line of the rotation center of the light source mounting shell is perpendicular to the extension line of the rotation center of the intermediate rotating shell, enabling the light source mounting shell to have two different swinging directions, resulting in a relatively wide range of irradiation angles of the light source. By driving the intermediate rotating shell to rotate through the first driving component, it is possible to drive the light source mounting shell to automatically swing in one direction, achieving a change in the irradiation angle of the light source. By driving the light source mounting shell to rotate through the second driving component, it is possible to make the light source mounting shell swing in the other direction, achieving a change in the irradiation angle of the light source.

[0010] By adopting the above technical solution, the first motor drives the first gear to rotate, driving the second gear meshing with the first gear to rotate. The rotation of the second gear drives the first rotating shaft to rotate, and the rotation of the first rotating shaft realizes the relative rotation of the intermediate rotating shell with respect to the bottom case.
[0011] Preferably, the bracket includes two support arms symmetrically arranged left and right around the center of the circular shell.

The stator of the outer-rotor motor is located inside the motor and is stationary. It extends a connecting shaft for easy connection. The support arm is connected through the connecting shaft. By adopting the above technical solution, the overall part of the outer-rotor motor is fixed to the light source mounting housing.

By driving the middle rotating shell to rotate through the first driving component, it is realized to drive the light source mounting shell to swing automatically in one direction, and the change of the light source irradiation angle is realized. By driving the light source mounting shell to rotate through the second driving component, it is realized that the light source mounting shell swings in the other direction, and the change of the light source irradiation angle is realized.

[0022] Refer to Figure 1 and Figure 2 As shown in, a lamp capable of automatically swinging includes a light source mounting housing 1, a bottom case 2, an intermediate rotating housing 3, a first driving assembly 4, and a second driving assembly 5.

A ball bearing is fixed to the inner wall of the annular platform 221, and the ball bearing is fixedly connected to the first rotating shaft 32 to support the rotation of the first rotating shaft 32.
[0023] Refer to Figure 1 and Figure 2, the first driving component 4 includes a first motor 41, a first gear 42, and a second gear 43.

The second gear 43 is fixed on the first rotating shaft 32, and the center of the second gear 43 is on the same straight line as the axis of the first rotating shaft 32. The first motor 41 drives the first gear 42 to rotate, driving the second gear 43 and the first rotating shaft 32 to rotate, realizing the rotation of the intermediate rotating shell 3 around itself. The outer peripheral wall of the circular housing 31 fits against the inner wall of the circular opening, closing the inside of the cylindrical outer housing 21, forming a closed protection space inside the cylindrical outer housing 21, playing a protective role for the first motor 41, and making it not easy for the external environment to damage the motor.
[0024] Refer to Figure 1 , the connecting plate 231 at the end of the connecting column 23 is used to connect with an external mounting frame. By passing bolts through the mounting through holes on the connecting plate 231 and connecting the bolts with the external mounting frame, the bottom shell 2 is fixed. And through the avoidance of the connecting column 23, it is convenient to twist the bolts, making the installation more convenient and adapting to different installation environments.
[0025] Refer to Figure 1 and Figure 2 , the light source mounting shell 1 includes a mounting shell 11 and two second rotating shafts 12 respectively arranged on opposite sides of the mounting shell 11. The axes of the two second rotating shafts 12 are on the same straight line. The mounting shell 11 is a closed shell structure with a hollow interior. A light emitting component 6 is installed inside the mounting shell 11. The light emitting component 6 is a pcb lamp board with LED lamp beads arranged thereon. A fixing frame 111 is provided inside the mounting shell 11 to fix the pcb lamp board. A light transmissive opening 112 is provided at a position between the two second rotating shafts 12 on one side of the mounting shell 11. A lens 113 is provided on the mounting shell 11 at the light transmissive opening 112 to close the light transmissive opening 112.

The bracket 33 includes two support arms 331 symmetrically arranged left and right around the center of the circular housing 31. Installation grooves are recessed on the opposite side surfaces of the two support arms 331. Ball bearings are fixed on the side walls of the two installation grooves. One second rotating shaft 12 penetrates into the installation groove of one support arm 331 and is fixedly connected to the ball bearing in the installation groove. The other second rotating shaft 12 penetrates into the installation groove of the other support arm 331 and is fixedly connected to the ball bearing in the installation groove. The second rotating shaft 12 is supported and rotates.
[0026] Refer to Figure 1 and Figure 2, the second driving component 5 includes a second motor 51 and a connecting housing 52. The second motor 51 is an outer-rotor motor. The rotor of the outer-rotor motor is located outside the motor and is responsible for providing rotational power. It has a motor housing. The stator of the outer-rotor motor is located inside the motor and is stationary. It extends a connecting shaft for easy connection. The rotor of the outer-rotor motor is connected to the connecting housing 52 through the motor housing. The connecting housing 52 is located inside the mounting housing 11 and is fixedly connected to the fixing frame 111. An end of a second rotating shaft 12 is provided with an opening that penetrates through the second rotating shaft 12 and the wall of the mounting housing 11 and communicates with the inside of the mounting housing 11. The connecting shaft on the stator of the outer-rotor motor passes through the opening and is fixedly connected to a support arm 331 through the second rotating shaft 12. The rotation center of the rotor of the outer-rotor motor is on the same straight line as the axis of the second rotating shaft 12. By rotating the rotor of the outer-rotor motor, the light source mounting shell 1 is driven to rotate around itself. The outer-rotor motor is installed in the mounting housing 11 for protection, reducing the situation of the motor being damaged by the external environment.
[0027] The axis line of the first rotating shaft 32 is the extension line of the rotation center of the middle rotating shell 3, and the axis line of the second rotating shaft 12 is the extension line of the rotation center of the light source mounting shell 1. The extension line of the rotation center of the light source mounting shell 1 is perpendicular to the extension line of the rotation center of the middle rotating shell 3, so that the light source mounting shell 1 has two different swinging directions, which is beneficial to a wider range of light source irradiation angles.
[0028] The implementation principle of a lamp capable of automatically swinging in this application is as follows: The first motor 41 drives the first gear 42 to rotate, driving the first rotating shaft 32 to rotate, thereby driving the middle rotating shell 3 to rotate. The rotation of the middle rotating shell 3 drives the light source mounting shell 1 to rotate coaxially, realizing the automatic swinging of the light source mounting shell 1 in one direction and the change of the light source irradiation angle. By driving the light source mounting shell 1 to rotate by itself through the second motor 51, the light source mounting shell 1 swings in another direction, realizing the change of the light source irradiation angle. There is no need to manually adjust, which is more convenient and helps to reduce the labor intensity of the staff.
