Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, and more specifically, to a stage lamp with a strong light beam feeling. Background Art

[0002] As a stage lighting fixture, stage lights often need to use effect lenses to change the shape, color, quantity and other effects of the light beam to project rich images. Among them, the light beam emitted by the light source is often divided into multiple beams using the spectral characteristics of the prism. In the prior art, prism superposition is generally used for effect rendering. However, the interval between the two superimposed prisms is short, and the edge of the light beam formed after the splitting is fuzzy, and the sense of the light beam is not strong. In addition, the superimposed prisms are generally arranged on the same panel. Considering the force of the driving motor, the number of prisms on the stage light will be limited, and the performance requirements cannot be well met. Utility Model Content

[0003] The utility model overcomes at least one defect of the prior art and provides a stage lamp with a strong light beam sense, which disperses the light beam emitted by the light source and finally significantly enhances the light beam sense of the dispersed light beam in the air.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a stage light with a strong sense of light beam, including a bottom chassis and a support arm pivotally connected to the bottom chassis, a lamp head is pivotally connected between the support arms, the lamp head includes a light source that emits a light beam, and includes a focusing lens group, a magnifying lens group and a light output lens group in sequence along the light beam emission direction, at least one first prism module is included between the focus of the light source and the magnifying lens group, and at least one second prism module is included between the magnifying lens group and the light output lens group.

[0005] The first prism module is arranged between the focus of the light source and the magnifying glass group, and the second prism module is arranged between the magnifying glass group and the light output lens group, so as to further increase the position distance between the first prism module and the second prism module, so that the light beam formed after the light beam passes through the first prism module and the second prism module forms a more obvious light beam sense; the first prism module and the second prism module are separately arranged on different panels to reduce the force on the driving motor when driving the focusing lens group / magnifying glass group to move up and down along the light beam direction, and also increase the number of prism sheets, further increasing the beam splitting pattern.

[0006] Furthermore, at least one first prism module is included between the focusing lens group and the magnifying lens group, and at least one second prism module is included between the magnifying lens group and the light output lens group. The first prism module is placed between the focusing lens group and the magnifying lens group where there is more space, thus saving space inside the stage light.

[0007] Furthermore, the focusing lens group further includes a first mounting plate for fixing the focusing lens, the first prism module is arranged on the first mounting plate, the magnifying lens group further includes a second mounting plate for fixing the magnifying lens, the second prism module is arranged on the second mounting plate. While the first prism module and the second prism module are arranged separately, the internal space of the stage light is reasonably used.

[0008] Furthermore, the first prism module is arranged on a side of the first mounting plate close to the magnifying lens group, and the second prism module is arranged on a side of the second mounting plate away from the magnifying lens group. The side of the first mounting plate close to the magnifying lens group and the side of the second mounting plate away from the magnifying lens group both have more room for movement, and will not affect the operation of the focusing lens group and the magnifying lens group.

[0009] Furthermore, the number of the first prism modules is 2, which are respectively located on both sides of the light beam, and / or the number of the second prism modules is 2, which are respectively located on both sides of the light beam. This is equivalent to increasing the number of prism sheets, and the two first prism modules / the second prism modules are respectively located on both sides of the light beam to balance the force on the panel that fixes the first prism module / the second prism module, thereby avoiding tilting or uneven force.

[0010] Furthermore, the first prism module includes a first carrier plate, and at least two prism sheets are pivotally placed on the first carrier plate. The first carrier plate can accommodate a plurality of prism sheets, and the plurality of prism sheets are stored and placed uniformly.

[0011] Furthermore, the first prism module includes a first driving motor for driving the first carrier plate to cut in and out of the light path, a first driving wheel, and a second driving motor for driving the first driving wheel. The outer edge of the pivot seat of each prism sheet is provided with meshing teeth, and the first driving wheel gear is driven by the meshing teeth of the prism sheet to drive the prism sheet to rotate. The prism sheet can cut in and out of the light path driven by the first driving motor and the second driving motor, and the prism sheet can rotate relative to the first carrier plate.

[0012] Furthermore, at least one atomizing lens is disposed on the first carrier plate, so that the atomizing lens and the prism lens are placed on the same first carrier plate, the internal space of the stage light is reasonably utilized, and the motor driving the atomizing lens is reduced while ensuring the atomization effect of the stage light.

[0013] Furthermore, the second prism module includes two second carrier plates pivoted to the same pivot axis, and one prism sheet is fixedly placed on the second carrier plate. The two second carrier plates are pivoted to the same pivot axis, which can reduce the number of drive motors and reduce the internal space occupied by the stage light. At the same time, placing one prism sheet on one second carrier plate can achieve a simple drive control method and a simple structure.

[0014] Furthermore, the second prism module includes a third driving motor and a second driving wheel that rotates synchronously with the third driving motor, the outer edge of each prism sheet pivot seat is provided with meshing teeth, and the second driving wheel meshes with the meshing teeth for transmission; and also includes a fourth driving motor that drives the second carrier plate to cut in / out of the light beam. The prism sheet can cut in and out of the light path under the drive of the third driving motor and the fourth driving motor, and the prism sheet can rotate relative to the second carrier plate.

[0015] Furthermore, the focusing lens group and the magnifying lens group are driven by independent driving mechanisms to move up and down along the light beam direction, thereby reducing the force on a single driving mechanism and avoiding the focusing lens group and the magnifying lens group from stalling during operation due to excessive force on the driving mechanism.
