In this rotator, when the light reflecting sheet 220 needs to be driven to move in a direction close to the center line of the bottom plate 210, the second motor 520 drives the rotating rod 530 to rotate, and the sliding sleeve 540 on the rotating rod 530 can limit the rotation of the rotating rod 530, so that the sliding sleeve 540 moves downwards on the rotating rod 530, at this time, the sliding sleeve 540 drives the light reflecting sheets 220 to rotate in a direction close to the center line of the bottom plate 210 through the plurality of driving rods 510, so that the light emitting structure formed by surrounding the light reflecting sheets 220 is reduced, the light transmitting gap is reduced, and when the light reflecting sheets 220 needs to be driven to move in a direction far from the center of the bottom plate 210, the second motor 520 drives the rotating rod 530 to rotate, the sliding sleeve 540 on the rotating rod 530 moves upwards, and drives the light reflecting sheets 220 to rotate in a direction far from the center line of the bottom plate 210 through the plurality of driving rods 510, so that the light emitting structure formed by surrounding the light reflecting sheets 220 is enlarged, and the light transmitting gap is enlarged.
The light source assembly is mainly used for outgoing light, and has various structural forms, in this embodiment, the light source assembly includes a light sheet 610 connected to the top side of the bottom plate 210, and a plurality of light beads 620 connected to the top side of the light sheet 610, and at least three light beads 620 can emit different color lights. When the lamp is in operation, different lamp beads 620 can be controlled to work, so that different colored lights are emitted outwards, and a richer light spot effect is obtained. In practical application, the lamp plate can be the spherical of upwards arching, and three be used for sending the lamp pearl 620 of achromatic light and be a banks, can be provided with a plurality of banks on the lamp plate, when the during operation, can make different chromatic light more even when outwards shining, improves the facula effect.
As a further improvement of the technical scheme, the light source assembly comprises a lamp sheet connected to the top side of the bottom plate and a plurality of lamp beads connected to the top side of the lamp sheet, and at least three lamp beads can emit mutually different colored lights. When the lamp is in operation, different lamp beads can be controlled to work, so that different colored lights are emitted outwards, and a richer facula effect is obtained.
With reference to fig. 3, as a further improvement of the above technical solution, the stage lamp further comprises a controller. The light-transmitting plate is carved with a Fresnel thread mark, and the Fresnel lens is formed by carving the Fresnel thread mark. When the emitted light passes through the light-transmitting plate, the light spot of the emitted light is changed under the action of the Fresnel thread marks. Therefore, the electronic control light-transmitting film is stuck on the light-transmitting plate and is controlled, so that the change of the form of the Fresnel thread mark on the light-transmitting plate is realized.
In this embodiment, 6 electrically controlled light transmissive films are adhered. A first electrically controlled light transmitting film 901, a second electrically controlled light transmitting film 902, a third electrically controlled light transmitting film 903, a fourth electrically controlled light transmitting film 904, a fifth electrically controlled light transmitting film 905, and a sixth electrically controlled light transmitting film 906, respectively. The control end of the first electrically controlled light transmission film 901, the control end of the second electrically controlled light transmission film 902, the control end of the third electrically controlled light transmission film 903, the control end of the fourth electrically controlled light transmission film 904, the control end of the fifth electrically controlled light transmission film 905 and the control end of the sixth electrically controlled light transmission film 906 are respectively connected with a controller. When the controller controls the electric control light-transmitting film, the controller can realize light transmission and non-light transmission. That is, when the controller outputs a high level to the electrically controlled light transmitting film, the electrically controlled light transmitting film realizes non-light transmission, and when the controller outputs a low level to the electrically controlled light transmitting film, the electrically controlled light transmitting film realizes light transmission.
Since the first electrically controlled light transmitting film 901, the second electrically controlled light transmitting film 902, the third electrically controlled light transmitting film 903, the fourth electrically controlled light transmitting film 904, the fifth electrically controlled light transmitting film 905 and the sixth electrically controlled light transmitting film 906 shield part of the chenille thread marks, respectively. Therefore, a high level can be output to a part of the electrically controlled light transmitting film and a low level can be output to a part of the electrically controlled light transmitting film. So that different forms of fresnel thread marks are produced on the light-transmitting plate. The different forms of the fresnel threads result in different adjustment of the focal length of the emitted light that can be provided by the light-transmitting panel. Through this, realize changing the function of the facula of sending out light for the sending out light of stage lamp is more gorgeous.
For some further embodiments, the controller is a single-chip microcomputer minimum system.
