BACKGROUND

With the continuous advancement of society and the development of technology, the manufacturing technology of display screens (which usually refer to LED display screens, or OLED display screens) is also maturing. The display screens are used more widely, in more and more occasions and methods, such as stage, exhibition and other occasions. In order to accommodate different needs, people sometimes splice a number of display screens into one large display screen, and sometimes requires the display screen to move, to increase the visual effect.

At present, the LED (also OLED) display screen is mostly a large-area display screen which is spliced by a plurality of LED display screens, which is fixedly installed in one place and plays some video text. When the content is not played, it is a big “blackboard”, which is rather dull. On the other hand, a few of the moving head stage lights in the prior art are also equipped with an LED display screen for displaying video text and the like. However, the support arm is fixedly connected with the outer frame of two sides of the LED display screen of the lamp head, and the LED display screen is difficult to be taken down separately as an ordinary LED display screen, and cannot be spliced into a large-area LED display screen.

In addition, in the embodiments shown in FIG. 1 to FIG. 14, both of the two fixed arms 3221 are disposed on the back surface of the display screen module 100, so that some mounting support structures are hidden on the back surface of the display screen module 100, to reduce the size, and improve the appearance. Moreover, the fixed arm 3221 is fixed to the back surface of the display screen module 100 instead of the two sides of the display screen module 100, so that it is convenient for the installation of the spot lamp 200. It should be noted that, in other embodiments, for example, as shown in FIG. 15, the fixed arms 3221 may be also disposed on the left and right sides of the display screen module 100. In this case, the spot lamps 200 may be only mounted on upper and lower sides of the display screen module 100. The fixed arms 3221 may be still rotatably connected to the holding plate 330. Alternatively, in an embodiment shown in FIG. 16, the fixed arms 3221 may be also disposed on left and right sides of the display screen module 100, but the spot lamps 200 may be disposed on each of upper, lower, left, and right sides of the display screen module 100, and the spot lamps 200 disposed on the left and right sides are located between the two fixed arms 3221.

Different from the above embodiments, in an embodiment shown in FIG. 17, the first motor 510 and the second motor 710 are not fixed to the inner side of the support arm 320, but the first motor 510 is fixed to the inner side of the holding plate 330, and the second motor 710 is fixed to the inner side of the base 310, to reduce the thickness and weight of the support arm 320. When the first motor 510 is fixed to the inner side of the holding plate 330, the second pulley 540 in the first drive mechanism is fixedly connected to the first bearing seat 420 or the first rotating shaft 410 fixed on the supporting arm 320, so that the first motor 510 rotates together with the holding plate 330 in the vertical direction. When the second motor 710 is fixed to the inner side of the base 310, the fourth pulley 740 in the second drive mechanism is fixedly connected to the second rotating shaft 610 or the second bearing seat 620 fixed on the supporting arm 320, so that the second pulley 740 can be driven by the second motor 710 to rotate, and in turn the entire support arm 320 can be driven to rotate in the horizontal direction.

Different from the above embodiments, in an embodiment shown in FIG. 18, one or two first motors 510 are fixed to the inner side of the support arm 320, and the second motor 710 is fixed to the inner side of the base 310. In this case, the second pulley 540 in the first drive mechanism drives the first rotating shaft 410 or the first bearing seat 420 fixed on the holding plate 330 to rotate, thereby realizing the rotation of the holding plate 330. The fourth pulley 740 in the second drive mechanism drives the second rotating shaft 610 or the second bearing seat 620 fixed on the supporting arm 320 to rotate, thereby realizing the rotation of the supporting arm 320. It should be noted that there may be one or two first drive mechanisms (including the first motor 510) in all embodiments of the present disclosure. When the number of the first drive mechanisms is two, each of the first drive mechanisms is located in one of the fixed arms 3221 respectively for driving the holding plate 330 to rotate on both sides of the holding plate 330.

In addition, it should be noted that the installation positions of the first drive mechanism and the second drive mechanism can be set according to actual needs, and the several embodiments shown herein are only for explaining the present disclosure and cannot be the limits of the scope of the present disclosure.

From the above, this invention can be used as an LED display screen to play a video and also realize the effect of stage lighting, which integrates multiple functions into one machine and presents a special and beautiful visual effect. Specifically, after power-on, the following effects can be achieved by control software: (1) the LED display screen module 100 can play video images; (2) the high-power LED spot lamp 200 emits light and changes colors; (3) LED display screen module 100 and the high-power LED spot lamp 200 are controlled to rotate in a vertical direction with respect to the support arm 320; (4) the support arm 320 is controlled to rotate in a horizontal direction with respect to the base 310; and (5) the combination of several effects in the above (1) to (4) can be simultaneously achieved.

There is any combination of the technical features of the above-described embodiments. For the sake of brevity of description, all possible combinations of the technical features in the above embodiments are not described. However, as long as there is no contradiction between the combinations of these technical features, it should be considered as the scope of this specification.

The above-described embodiments are merely illustrative of several embodiments of the present disclosure, and the description thereof is more specific and detailed, but is not to be construed as limiting the scope of the disclosure. It should be noted that a number of variations and modifications may be made by those skilled in the art without departing from the spirit and scope of the disclosure.
