Description

TECHNICAL FIELD

[0001] The utility model relates to stage lamp technical field more particularly, it is a stage lamp with translational rotatable effect disc. BACKGROUND

[0002] In order to realize rich stage effect, various effect discs are arranged in stage lamp to interfere with light beam to produce light effect, and part of effect discs need to be selectively cut into and cut out of light path and rotate in light path.When the area of effect disc is larger, if it is cut into and cut out of light path in the way of swinging, it will occupy larger space, and if the rotation driving mechanism of effect disc moves along with effect disc, it will also cause problems of wiring difficulty, weight balance and space avoidance, resulting in complex driving mechanism. SUMMARY

[0003] The utility model provides a stage lamp with translational rotatable effect disc to drive effect disc in the way of translation, and the second driving mechanism for driving effect disc to rotate is fixed in position relative to the first driving mechanism for driving effect disc to translate.

[0004] To solve the above technical problem, the utility model adopts the technical scheme of a stage lamp with translational rotatable effect disc, which comprises a light source for emitting light beam in a lamp head, a translatable mounting plate, an effect disc pivotally connected to the mounting plate, a first driving mechanism for driving the mounting plate to translate, and a second driving mechanism for driving the effect disc to rotate.Under the drive of the first driving mechanism, the effect disc on the mounting plate can selectively cut into and cut out of the light path, and the second driving mechanism is fixed in position relative to the first driving mechanism and drives the effect disc to rotate through a second synchronous belt, which is used to drive a section of the effect disc to rotate in the same direction as the translation direction of the mounting plate.

[0005] The stage lamp with translational rotatable effect disc changes the movement mode of the effect disc to translation, reduces the space occupied by its activity range, and fixes the second driving mechanism for driving the effect disc to rotate in position relative to the first driving mechanism for driving the effect disc to translate, i.e.the second driving mechanism does not follow the translation of the effect disc, avoiding the need for space avoidance corresponding to the movement of the second driving mechanism in the lamp head, saving space and reducing the connection difficulty of power and signal cables of the second driving mechanism.

[0006] Further, the effect disc is a dynamic disc, and light transmission holes are formed in the radial direction outward from the rotation center of the effect disc.After the effect disc cuts into the light beam, the light beam is blocked by the effect disc and can only be emitted from the light transmission holes, so as to form corresponding patterns on the projected light spot and produce light effect.

[0007] Further, the effect disc has a first stop position and a second stop position for interfering with the light path under the driving of the first driving mechanism, and when the effect disc is in the second stop position, the angle between the direction of the radius extending from the center of the effect disc to the center of the light beam and the direction of the radius extending from the center of the effect disc to the center of the light beam when the effect disc is in the first stop position is 80°-100°. In this way, the two patterns projected by the light-transmitting hole when the effect disc is in the first stop position and the second stop position are in a substantially perpendicular state, for example, the imaging of the light-transmitting hole in the light spot is in a horizontally extending state when the effect disc is in the first stop position, and the imaging of the light-transmitting hole in the light spot is in a vertically extending state when the effect disc is in the second stop position.

[0008] Further, the mounting plate is pivotally connected with a transmission wheel, the transmission wheel is engaged with the effect disc, and the second synchronous belt drives the effect disc to rotate by driving the transmission wheel to rotate. The transmission wheel can effectively reduce the space occupied by the second synchronous belt, and the second synchronous belt does not need to surround the entire effect disc to drive the effect disc.

[0009] Further, the transmission wheel is coaxially connected with a conversion wheel, and the second synchronous belt is engaged with the conversion wheel. The conversion wheel can adjust the height of the second synchronous belt relative to the effect disc, thereby facilitating the installation of the second synchronous belt.

[0010] Further, the mounting plate is further pivotally connected with two steering wheels on one side of the conversion wheel, and the second synchronous belt sequentially passes through one of the steering wheels, the conversion wheel, and the other steering wheel. The two steering wheels can make the second synchronous belt closely contact with the conversion wheel, so that the second synchronous belt can better drive the conversion wheel.

[0011] Further, the mounting plate is further pivotally connected with two steering wheels on one side of the conversion wheel, and the second synchronous belt sequentially passes through one of the steering wheels, the conversion wheel, and the other steering wheel. The two steering wheels can make the second synchronous belt closely contact with the conversion wheel, so that the second synchronous belt can better drive the conversion wheel.

[0012] Further, the mounting plate is further pivotally connected with two steering wheels on one side of the conversion wheel, and the second synchronous belt sequentially passes through one of the steering wheels, the conversion wheel, and the other steering wheel. The two steering wheels can make the second synchronous belt closely contact with the conversion wheel, so that the second synchronous belt can better drive the conversion wheel.

[0013] Further, a first driving gear is fixed on the driving shaft of the first driving mechanism, the first synchronous belt surrounds the first driving gear and a first driven gear, and the sliding block is located between the first driving gear and the first driven gear. The first driving gear and the first driven gear pull the first synchronous belt, thereby driving the sliding block.

[0014] Further, a rotating wheel is pivoted on the pivoting column of the first driven gear of the driving shaft of the first driving mechanism, the second synchronous belt surrounds the two rotating wheels, and is driven to rotate by a second driving gear on the second driving mechanism. The second synchronous belt can save space by borrowing the installation shaft of the first driving gear and the first driven gear.

[0015] Further, a tensioning wheel is further arranged between the first driving gear and the second driving gear, the second synchronous belt surrounds the first driving gear, the second driving gear and the tensioning wheel in sequence and is driven to cooperate with the effect disc. The tensioning wheel can pull the second synchronous belt and change the position of the second driving gear according to requirements, thereby making the position selection of the second driving mechanism more flexible.

[0016] Further, an arm supporting the rotation of the lamp head and a case supporting the rotation of the arm are further included. Through the rotation of the lamp head and the arm, the light emitted by the light source can be directed to any direction. BRIEF DESCRIPTION OF DRAWINGS

[0026] The stage lamp with the translational rotatable effect disc reduces the space occupied by the moving range of the effect disc 130 by changing the moving mode of the effect disc 130 to translation, and sets the second driving mechanism 150 for driving the effect disc 130 to rotate to be fixed relative to the position of the first driving mechanism 140 for driving the effect disc 130 to translate, that is, the second driving mechanism 150 does not follow the effect disc 130 to translate, avoids the space avoidance corresponding to the movement of the second driving mechanism 150 in the lamp head 100, saves the space, and reduces the connection difficulty of the power / signal cable of the second driving mechanism 150, and the second synchronous belt 151 is used for driving a section of the effect disc 130 to rotate in the same direction as the translation direction of the mounting plate 120, so that the distance between the effect disc 130 and the section of the second synchronous belt 151 is unchanged in the process of the translation of the effect disc 130, so that different positions of the section of the second synchronous belt 151 can drive the effect disc 130 in turn in the process of the translation of the effect disc 130.
