Description

Technical Field

[0001] The present application relates to the technical field of stage lights, and in particular to a rotating strip light fixture. Background Art

[0002] In order to create a beautiful stage atmosphere, it is necessary to set up a long light strip on the stage. The lamp beads on the light strip change different colors or flicker with the change of music. And the distance between the two lamp beads should be equidistant, which gives the audience a neat and symmetrical beauty. Due to the limited length of a single strip light, it is often necessary to splice multiple strip lights together, which not only requires the arrangement distance of the lamp beads inside the strip light to be equal, but also the arrangement of the lamp beads between the lights to be equidistant. The existing strip lamps with Y-axis shaking function in stage lights usually have the transmission mechanism of the Y-axis shaking head placed on the side. In order to achieve the splicing of lamps and lamps, the distance between the most side lamp bead of the lamp and the nearest lamp bead of the adjacent lamp is equal to the distance between the two adjacent lamp beads of the lamp, that is, the lamp beads of the lamps can be seamlessly spliced ​​at equal distances. At present, the pulley of the Y-axis drive structure is generally placed outside the lens, because of the thickness of the Y-axis pulley and the clearance required for the arm to pass through the power harness and signal harness of some head lamp bead driver boards, which requires the lamp beads to be farther apart. This results in a smaller number of lamp beads that can be arranged on a lamp of a certain length, a less diverse beam effect, and a thicker arm. Utility Model Content

[0027] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0028] Reference Figures 1 to 4 The rotating strip lamp of the present application includes a base 100, a lighting unit 200 and a driving unit.

[0029] Specifically, connecting arms 110 are respectively disposed on both sides of the base 100 , and the connecting arms 110 are disposed along the vertical direction.

[0030] The lighting unit 200 includes a rotating frame 210 and a plurality of light sources 220. Both ends of the rotating frame 210 are rotatably connected to the connecting arm 110. The light sources 220 are disposed on the rotating frame 210 and are arranged in at least one column or one row in an array along the length direction of the rotating frame 210. Two times the distance b between the light sources 220 on both sides of the rotating frame 210 closest to the ends of the rotating frame 210 and the connecting arm 110 is less than or equal to the distance a between two adjacent light sources 220, so that rotating strip lamps of the same type can be seamlessly spliced. It should be noted that when two times the distance b is less than the distance a, the maximum error between twice the distance b and the distance a should not exceed 10 mm.

[0031] The driving unit is disposed at the bottom of the rotating frame 210 , and is used to drive the lighting unit 200 to rotate. When the lighting unit 200 rotates, the driving unit rotates along with the lighting unit 200 .

[0032] In the prior art, the driving unit is generally fixed on the base 100 and is generally hidden in the connecting arm 110. The transmission structure of the driving unit and the related wiring harness are integrated in the connecting arm 110. This may easily lead to the thickness of the connecting arm 110 being too thick, and thus the distance between the light source closest to the end of the lamp and the end of the lamp is too large. In order to enable two lamps to be spliced ​​and used, the distance between two adjacent light sources on a lamp should generally be greater than or equal to the distance between the light source closest to the end of the lamp and the end of the lamp. Because the distance between the light source closest to the end of the lamp and the end of the lamp cannot be further reduced, the number of light sources that can be arranged on a lamp of a certain length is relatively small, and the light beam effect is not so diverse.

[0033] The embodiment of the present application optimizes the structure of the connection part related to the lighting unit 200 and the driving unit, installs the driving unit used to drive the lighting unit 200 to rotate at the bottom of the lighting unit 200, and makes the driving unit rotate with the lighting unit 200, effectively utilizing the space at the bottom of the lighting unit 200 that does not block light. Compared with the existing design in which the driving unit does not rotate with the lighting unit 200 and the transmission part of the driving unit is set on the connecting arm 110, the present application can design the connecting arm 110 to be more compact and enable the connecting arm 110 to be used for hiding the wiring harness. At the same time, it can also reduce the distance between the center of the light source at the side of the strip lamp and the side of the lamp, which is equivalent to the required distance between the two adjacent light sources being smaller. In this way, on a lamp of a certain length, the number of lamp beads that can be arranged is relatively large, and the thickness of the connecting arm can be made very thin.

[0034] In the embodiment of the present application, the light source 220 is generally an LED lamp bead, and a heat sink 230 for dissipating heat from the LED lamp bead is provided on the rotating frame 210. The LED lamp bead is arranged on the heat sink 230, and a lens 240 is provided above the LED lamp bead. The driving unit is provided at a position adjacent to the heat sink 230 on the rotating frame 210.

[0035] In the present application embodiment, Figure 3As shown, the driving unit includes a motor 310, a driving wheel 320, a transmission belt 330 and a driven wheel 340. The motor 310 is fixed to the rotating frame 210, the driving wheel 320 is fixed to the output shaft of the motor 310, the driven wheel 340 is fixed to the connecting arm 110, and the driven wheel 340 is connected to the driving wheel 320 through the transmission belt 330. Specifically, the rotating frame 210 is provided with a mounting seat 250 for fixing the motor 310. When the motor 310 drives the driving wheel 320 to rotate, because the transmission belt 330 is connected to the driven wheel 340, and the driven wheel 340 is fixed to the connecting arm 110, that is, the driven wheel 340 is fixed and motionless. In normal use, the base 100 is fixed, and when the motor 310 is started, it can drive the entire lighting unit 200 to rotate.

[0036] The driven wheel in the prior art rotates together with the lighting unit 200, while the driven wheel 340 of the present application is fixed. In addition, the driven wheel 340 is not integrated on the connecting arm 110, thereby reducing the design difficulty of the connecting arm 110 and making the thickness c of the connecting arm 110 thinner.

[0037] like Figure 6 As shown, when the motor 310 is placed on the lighting unit 200, the center distance n between the driving wheel 320 and the driven wheel 340 is smaller than Figure 5 The center distance m of the motor 310 shown in the figure is reduced when it is placed on the base 100, that is, n<m, and the angle β>θ formed by the transmission belt 330, the driving wheel 320 and the driven wheel 340 is reduced. At this time, the number of 3M teeth of the transmission belt 330 and the driving wheel 320 that mesh with each other is reduced, and the pressure evenly distributed to each tooth is increased, which increases the wear probability of the belt teeth or the driving wheel teeth. In order to avoid this situation, a tensioning structure is specially added.

[0038] Further, in the embodiments of the present application, Figure 7 and Figure 8 As shown, the driving unit also includes a tensioning structure capable of adjusting the tension of the transmission belt 330. The tensioning structure includes a rotatable tensioning wheel 360 and a pre-stressing member 350. The tensioning wheel 360 provides pre-pressure to the portion of the transmission belt 330 between the driven wheel 340 and the driving wheel 320 under the action of the pre-stressing member 350, so as to prevent the transmission belt 330 from loosening and then slipping and failing to transmit after long-term use.

[0039] In addition, the provision of the tensioning structure increases the number of teeth that mesh with the driving wheel 320 and the transmission belt 330, and reduces the pressure assigned to each tooth, thereby reducing the probability of wear of the belt teeth or the driving wheel teeth.

[0040] And in this application, if Figure 8As shown, there are two groups of tensioning structures, which are respectively arranged on both sides of the line connecting the center point of the driven wheel 340 and the center point of the driving wheel 320. Under the action of the pre-pressing member 350, the tensioning wheel 360 makes the part of the transmission belt 330 between the driven wheel 340 and the driving wheel 320 approach each other, thereby realizing automatic tensioning adjustment of the transmission belt 330.

[0041] In some examples, the driven wheel 340 is larger than the driving wheel 320, and the rotating shaft 370 of the tensioning wheel 360 is slidably set on the rotating frame 210 so that the tensioning wheel 360 can approach the driven wheel 340 or the driving wheel 320. Specifically, a limiting plate 260 for the sliding of the rotating shaft 370 is provided on the mounting seat 250, and a waist-shaped groove is provided on the mounting seat 250. The limiting plate 260 is slidably set on the mounting seat 250 by passing a bolt through the waist-shaped groove, so that under the action of the pre-stressing member 350, the tensioning wheel 360 can approach the driven wheel 340 or the driving wheel 320, wherein one end of the pre-stressing member 350 is fixed to a position of the rotating frame 210 close to the center of the driven wheel 340 (specifically fixed on the mounting seat 250), and the other end is connected to the rotating shaft 370, wherein the pre-stressing member 350 is a tension spring.

[0042] Use one end of the tension spring to hook the mounting seat 250 and the other end to hook the limiting plate 260. First install the transmission belt 330, hook one end of the tension spring to the mounting seat 250, then pull up the other end of the tension spring, hook the limiting plate 260, and finally lock the mounting seat 250 to the rotating frame 210. In this way, the tightness of the belt is just right, which is convenient for workshop assembly operations and ensures the consistency of the belt tightness, ensuring that the belt will not break.

[0043] One side of the tension wheel 360 has a step to prevent the transmission belt 330 from running out during movement.

[0044] In some embodiments, Figure 1 As shown, a gap 113 for wiring is provided inside the connecting arm 110, and the thickness of the gap 113 is controlled to be 5 to 7 cm so that some wiring harnesses of some head lamp bead boards, drive boards, and signal boards can pass through.

[0045] Furthermore, the connecting arm 110 includes a first shell 111 and a second shell 112, the first shell 111 is connected to the second shell 112 to form a gap 113, and the rotating frame 210 is connected to the second shell 112 through a rotating structure. The rotating structure includes a rotating shaft 123 and a bearing seat, the rotating shaft 123 is fixedly connected to the second shell 112, and the middle part of the rotating shaft 123 is hollowed out and connected to the gap 113, so that some wiring harnesses of some head lamp bead boards, drive boards, and signal boards can enter the gap 113 through the hollowed-out part.

[0046] The driven wheel 340 is fixedly connected to the rotating shaft 123 , the bearing 122 on the bearing seat is sleeved on the rotating shaft 123 , and the connecting plate 121 on the outer ring of the bearing 122 is fixedly connected to the rotating frame 210 , wherein the bearing 122 is a flange bearing.

[0047] In some embodiments, an optical coupling disc is provided on the driving wheel 320, and an optical coupling plate is provided on the mounting base 250 of the motor 310. The optical coupling plate and the optical coupling disc cooperate to detect the current position of the rotating frame 210. When the lighting unit 200 is accidentally touched, the offset displacement is given to the motor 310 for correction feedback under the monitoring of the optical coupling plate and the optical coupling disc, so as to achieve automatic error correction and return of the lighting unit 200.

[0048] In some embodiments, a notch 101 for avoiding the driving part is provided at a position of the base 100 directly opposite to the driving part, so that the lighting part 200 can rotate normally.

[0049] like Figure 4 As shown, in order to realize the splicing of strip lamps with shaking head function, the lamp beads of the adjacent lamps can be seamlessly spliced ​​with equal distance, that is, x = a, and the number of lamp beads arranged in the lamp is as large as possible. Figure 4 When the length of the lamp is constant, the smaller the value of a (i.e. the distance between two adjacent lamp beads), the smaller the value of b=1 / 2 of X, and the more lamp beads are arranged in the lamp.

[0050] according to Figure 4 As shown, the lamp structure of the present application places the driving structure below the lighting unit 200, and utilizes a portion of the space below the lighting unit 200 that does not block light. Therefore, the distance b between the leftmost lamp bead of the lamp and the leftmost lamp of the lamp can be smaller, and a=2b can also be smaller. When the length y of the lamp is constant, the larger the number of lamp beads n=y / a, the more lamp beads can be arranged. Accordingly, because the width of the driving mechanism is reduced, the thickness c of the connecting arm can be made very thin.

[0051] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
