These directional terms should be understood in the context of the structures and functions described herein, and should not be interpreted to limit the application to only those embodiments specifically described herein.

[0051] The track lamp 10 in the present application comprises a track 1, a lamp body 3 and a control unit, wherein the lamp body 3 is arranged to be movable along the track 1, and the control unit is connected with the lamp body 3 and can control the lamp body 3 to move according to requirements. For example, the control unit can control the lamp body 3 to move to any target position, or to move to the target position in a fast or slow or point-by-point manner according to requirements, without the need for manual operation to move the lamp body 3, which is simple and convenient.

[0052] In the specific embodiment shown in FIG. 1, the track lamp 10 further comprises a positioning strip 4, a main body 2, a power wheel, a driving motor 6 and a motor controller, wherein the positioning strip 4 extends along the extension direction of the track 1 and is connected with the track 1. The main body 2 is located in the track 1 and is movably connected with the positioning strip 4. The lamp body 3 is arranged on the main body 2 and is assembled in a lamp body assembly seat on the main body 2 through a connecting column. The power wheel is connected with the main body 2, and the power wheel and the positioning strip 4 are continuously positioned and forced through positioning points during rotation of the power wheel, and the main body 2 is driven to move on the track 1. The positioning force of the positioning points acts on the force points in the direction of the positioning strip 4, and is used to support the movement of the main body 2 on the track 1.

[0053] A driving motor 6 is installed on the main body 2 and connected with the power wheel, which can drive the power wheel to rotate, and the power wheel continuously locates the force with the positioning strip 4 during rotation, and drives the main body 2 and the lamp body 3 to move along the extension direction of the track 1. The motor controller is connected with the driving motor 6, which is used for controlling the operation of the driving motor 6. The motor controller is connected with the control unit, which can be used for controlling the rotating speed of the driving motor 6, and can also control the power supply of the driving motor 6 to be cut off, so that the driving motor 6 stops operating. The control unit is used for controlling the operation of the motor controller.

[0054] Regarding the specific structure of the power wheel and the positioning strip 4, the application provides three specific embodiments, which can also be other equivalent or similar technical solutions, and the three embodiments are as follows. In the first embodiment, the power wheel is a gear, the positioning strip 4 is a rack, the positioning point is the meshing point of the gear and the rack, and the force point is the contact point between the tooth groove side wall on the rack and the tooth outer wall on the gear. During the rotation of the power wheel, the tooth groove side wall supports the tooth outer wall to provide force for the power wheel, and moves, the supporting force is strong, and it will not slip and fall, which can well meet the demand of vertical movement and climbing.

[0055] In the second embodiment, the power wheel is a gear, the positioning strip 4 is a punched strip, the positioning point is the meshing point of the gear and the hole on the punched strip, and the force point is the contact point between the hole inner wall on the punched strip and the tooth outer wall on the gear. During the rotation of the power wheel, the hole inner wall supports the tooth outer wall to provide force for the power wheel, and moves, the supporting force is strong, and it will not slip and fall, which can well meet the demand of vertical movement and climbing.

[0056] It can be seen that in the track lamp 10 in the application, a unique power wheel and positioning strip 4 structure is adopted, and the force point between the power wheel and the positioning strip 4 can provide supporting force during the rotation of the power wheel. The supporting force can resist the vertical gravity, so that after the track lamp 10 is installed vertically or vertically inclined, the main body 2 and the lamp body 3 thereon can also move on the track 1, and will not slip and fall.

[0057] The application relates to a control method of the track lamp 10, and the track lamp 10 further comprises a positioning sensing device, which is connected with the control unit in a signal mode and is used for sensing the position of the lamp body 3.

[0058] The control method of the track lamp 10 comprises the following steps.

[0059] S1, based on the position of the target area indicated by the received control instruction, the lamp body 3 is controlled to move along the track 1;

[0060] S2, the position signal of the lamp body 3 collected by the positioning sensing device is acquired; and

[0061] S3, judging whether the lamp body 3 is located in the target area according to the position signal of the lamp body 3 collected by the positioning sensing device, if the lamp body 3 is located in the target area, controlling the lamp body 3 to stop moving; if the lamp body 3 is not located in the target area, controlling the lamp body 3 to continue moving along the track 1.

[0062] In a museum or other exhibition hall, the target area is the cultural relics to be displayed. In an exhibition hall, the target area is the position of the art to be exhibited.

[0063] In an embodiment, the positioning sensing device comprises a plurality of photoelectric position sensors installed on the front side and / or the rear side of the lamp body 3. Of course, in practice, for the sake of aesthetics, the photoelectric position sensors can also be installed in the main body 2 and located in the track 1. The photoelectric position sensors can sense the position of the lamp body 3 or the main body 2, as well as the speed of the lamp body 3 or the main body 2. After receiving the position signal of the photoelectric position sensor, the control unit can determine whether the lamp body 3 has reached the target area according to the position signal. If the target area is reached, the lamp body 3 is controlled to stop moving. If the target area is not reached, the lamp body 3 is controlled to continue moving until the target area is reached.

[0064] In step S3, the control unit can also control the motor controller according to the signal of the photoelectric position sensor, and the motor controller controls the driving motor 6 to speed up, slow down or stop running according to the instruction of the control unit, so as to adjust the moving speed of the lamp body 3.

[0065] Optionally, the track lamp 10 further comprises an encoder connected with the driving motor 6, for sensing the number of revolutions of the driving motor 6. Of course, the number of revolutions of the driving motor 6 can also be detected by a photoelectric sensor instead of the encoder.

When the control unit receives the positioning code information, it can determine whether the target area is the specific target area. If the positioning code collected is different from the positioning code of the specific target area, the control unit controls the lamp body 3 to continue moving. If the positioning code information is the positioning code information in the specific target area, the control unit controls the lamp body 3 to stop moving. The code reader can be a camera or a code scanning gun, or other devices.

[0068] Specifically, the plurality of positioning codes can be arranged on the inner side of the track 1, and can be located on both sides of the main body 2.

When it is needed to exhibit, the lamp body 3 is moved to the position of the positioning code by the control unit, so that the cultural relics or works exhibited at the position can be illuminated. Of course, the more positioning codes, the more flexible the position of the works, and the number of positioning codes can be set according to the needs. Of course, in the case where there is no positioning code, the human eye can be used to determine whether the lamp body 3 is in place and to make fine adjustment.
