[0026] like Figure 1 and 2 As shown, a track spotlight capable of changing the direction of irradiated light is provided, comprising a lamp tube 6, a first steering assembly, a connecting rod 12, a second steering assembly and a power supply box 13. The lamp tube 6 is rotatably connected to the connecting rod 12 through the first steering assembly, thereby realizing the up and down shaking rotation of the lamp tube 6 in the vertical plane direction; the connecting rod 12 is rotatably connected to the power supply box 13 through the second steering assembly, thereby realizing the left and right shaking rotation of the lamp tube 6 in the horizontal plane direction.

[0027] The front end of the lamp tube 6 is equipped with a front ring 1, a lens 2, a light source bracket 4 and a light source 5. Specifically, the light source 5 is fixedly mounted on the light source bracket 4. When assembling the light source 5, a heat dissipation paste is applied to dissipate the heat of the light source 5. The light source bracket 4 is fixedly mounted on the front end of the lamp tube 6 by screws 3. Furthermore, the light source 5 is located between the light source bracket 4 and the end of the lamp tube 6. The front end of the light source bracket 4 is provided with a lens 2, and the front end of the lens 2 is provided with a front ring 1. After the internal thread of the front ring 1 is threadedly connected with the external thread of the lamp tube 6, the lens 2 and the light source bracket 4 are tightened to ensure that the lens 2 does not shake.

[0028] The tail of the lamp tube 6 is connected with a lamp tube cover 10 , and the lamp tube cover 10 is snapped into the step provided in the lamp tube 6 by a buckle provided with a step so as to achieve position limiting and fixing.

[0029] The lamp tube 6 is rotatably connected to the connecting rod 12 through the first steering assembly, so as to realize the up and down shaking rotation of the lamp tube 6 in the vertical plane direction. Specifically, the first steering assembly includes a fixed bracket 7, a first stepper motor 8 with a gear transmission shaft, and a first gear 9. The housing of the first stepper motor is fixedly mounted on the mounting plate at the top of the connecting rod 12, the gear part of the gear transmission shaft of the first stepper motor is meshed with the first gear 9, one side of the first gear 9 is rotatably mounted on the mounting plate at the top of the connecting rod 12 through the connecting shaft, and the other side of the first gear 9 is fixedly connected to the fixed bracket 7 through the connecting shaft, and the fixed bracket 7 is fixedly mounted on the lamp tube 6. The back of the first gear 9 is connected to a limiting assembly, and the limiting assembly includes a limiting plate 11 and a stop column, wherein the limiting plate 11 is connected to the connecting shaft of the first gear 9, and the stop column is fixedly mounted on the mounting plate at the top of the connecting rod 12. When the first gear 9 rotates, the limiting plate 11 rotates synchronously, and finally abuts against the stop column to limit the rotation angle of the first gear 9, that is, to limit the rotation angle of the lamp tube 6. Furthermore, the lamp tube 6 is provided with a slot matched with the connecting rod 12 , and the connecting rod 12 passes through the slot and extends to the inside of the lamp tube 6 . Therefore, the lamp tube 6 can be rotated up and down through the slot without abutting against the connecting rod 12 .

[0030] In the above structure, the wheel surface of the first gear 9 is vertically arranged, so the first gear 9 rotates on the vertical plane, thereby driving the fixed bracket 7 to rotate on the vertical plane, and finally allowing the lamp tube 6 to rotate up and down in the vertical direction.

[0031] The connecting rod 12 is rotationally connected to the power box 13 through the second steering assembly, so as to realize the left and right shaking rotation of the lamp tube 6 in the horizontal direction. Specifically: the second steering assembly includes a second stepper motor 18 with a gear transmission shaft and a second gear 19. The housing of the second stepper motor is fixedly installed in the power box 13, the gear part of the gear transmission shaft of the second stepper motor is meshed with the second gear 19, and the second gear 19 is fixedly connected to the bottom end of the connecting rod 12; wherein, the bottom end of the connecting rod 12 passes through the power box 13 and extends to the inside of the power box 13, and the connecting rod 12 is rotationally connected to the power box 13 through a bearing. A gear protection sheet 16 is provided on the top of the second gear 19, and the gear protection sheet 16 is fixedly installed on the inner wall of the power box 13 by screws 3. The power box cover 17 is fixedly installed at the bottom of the power box 13 by screws 3.

[0032] In the above structure, the wheel surface of the second gear 19 is arranged horizontally, so the second gear 19 rotates on the horizontal plane, thereby driving the connecting rod 12 to rotate on the horizontal plane, and finally allowing the lamp tube 6 to rotate left and right in the horizontal direction.

[0033] A power supply (not shown in the figure), a power driver 14 and a controller 15 are fixedly installed in the power box 13 by screws 3. The connecting rod 12 is provided with a hollow wiring hole for routing the power supply lines of the light source 5 and the second stepper motor. The power supply is used for the working power supply of the first stepper motor, the second stepper motor and the light source 5, and the controller 15 is used for the working operation of the first stepper motor, the second stepper motor and the light source 5. It should be noted that the process algorithms and programs involved in the working process of the power driver 14 and the controller 15 in the utility model are not within the protection scope of the utility model, and are only used by those skilled in the art to understand that the controller 15 in the utility model is used to control the working operation of the first stepper motor, the second stepper motor and the light source 5, and the power driver 14 drives the working operation of the power supply.

[0034] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any technician familiar with the field can make many possible changes and modifications to the technical solution of the utility model by using the above disclosed methods and technical contents without departing from the scope of the technical solution of the utility model, or modify it into an equivalent embodiment of equivalent changes.
