Description

Stage lamp with effect module having brake function

Technical Field

The invention relates to the technical field of stage lamps, in particular to a stage lamp with an effect module having a braking function.

Background

The stage lamp on the market realizes focusing and magnifying effects through the focusing lens group and the magnifying lens group respectively, and changes definition and size of patterns projected by the stage lamp. The focusing lens group or the amplifying lens group moves along the main optical axis under the driving of the driving component, and is locked at the working position by providing torque through the motor after reaching a preset position; after the stage lamp outage, the motor stop work has lost the moment of locking to these effect subassemblies, and along with the removal of stage lamp and freely slide under the effect of gravity, produce the abnormal sound with adjacent module striking easily, damage the inside components and parts of stage lamp even after the striking, cause the loss.

Disclosure of Invention

The invention aims to overcome at least one defect in the prior art, and provides the stage lamp with the effect module having the braking function, which is used for solving the problem that the effect module is easy to collide with an adjacent component after power failure.

In order to solve the technical problems, the invention adopts the technical scheme that: a stage lamp with effect modules having a braking function comprises a light source module for generating light beams, an effect component for intercepting the light beams and generating lighting effects, a driving component for driving the effect component to move back and forth along a main optical axis of the light beams, and a braking module for braking the effect component after the driving component is powered off, wherein the braking module is provided with a braking piece, when the braking module is powered on, the braking piece contracts, and when the braking module is powered off, the braking piece pops up to brake the effect component.

By arranging the driving module directly acting on the effect assembly, generally, after the driving assembly is powered off, the braking module can be powered off, the braking piece is popped out to directly brake the effect assembly, the sliding speed of the effect assembly is reduced or the effect assembly is limited to slide by direct braking, and abnormal sound and even damage caused by the fact that the effect assembly is collided with an adjacent component at an excessively high speed in the free sliding process after the locking force of the driving module is lost are avoided; when the brake module is energized, the brake pads are retracted to prevent braking of the effect assembly when it is in operation.

Further, the effect component also comprises a brake pad which is arranged corresponding to the brake pad. Interaction between the brake pads, such as when braking by friction, avoids wear on the effect assembly during braking.

Furthermore, the brake module further comprises a magnetic attraction piece and a reset piece, when the brake module is in a power-on state, the magnetic attraction piece generates magnetic force to attract the brake block to keep shrinking, when the brake module is in a power-off state, the magnetic attraction piece disappears, and the reset piece pushes or pulls the brake block to pop up to brake the effect assembly. The magnetic attraction piece capable of switching the state is arranged, the brake block is attracted by magnetism to keep the brake block to shrink, the condition that the operation of the effect assembly is influenced is avoided, the reset piece is arranged to act on the brake block to brake the effect assembly, and the state switching of the magnetic attraction piece is simple.

Further, the brake module is located on one side of the effect component in a direction perpendicular to the main optical axis, and the length direction of the brake pad is parallel to the main optical axis of the light beam. The arrangement can utilize the brake block to rub with the effect component to complete braking, and the brake module is arranged on one side, so that light can be prevented from entering an effective light beam and being shielded, and even the pattern light spot which is finally projected can be prevented from being directly imaged.

Further, the brake module is located on a side of the effect assembly away from the drive assembly. The arrangement can enable the forces of the brake module and the driving assembly acting on the effect assembly at the same time to be more balanced, and the effect assembly is prevented from deviating from the light beam or being damaged by the effect assembly due to uneven stress.

Furthermore, the number of the magnetic parts is multiple, and the magnetic parts are distributed along the length direction of the brake pad. The arrangement strengthens the attraction force of the magnetic attraction piece to the brake pad when the magnetic attraction piece is electrified, and prevents the brake pad from being incapable of completing the whole piece shrinkage due to unbalanced attraction force.

Further, the length of the brake pad is greater than or equal to the stroke of the movement of the effect assembly. With the arrangement, after the driving assembly is powered off, the effect assembly can be braked by the brake module at any position, so that the effect assembly is prevented from generating collision abnormal sound or collision damage due to too high speed in the free sliding process.

Further, the brake module also includes a guide that limits movement of the brake pad in a direction toward or away from the effect assembly. By arranging the guide member to limit the brake pad to move only in a direction close to or far away from the effect component, the brake pad is prevented from being incapable of completely surface contact with the effect component due to deviation of the moving direction, and the braking effect is influenced.

Furthermore, the brake block is located on one side of the magnetic attraction piece close to the effect component, the guide piece comprises a limiting hole penetrating through the brake block and a positioning screw matched with the limiting hole, and the positioning screw penetrates through the limiting hole and then is fixed on the magnetic attraction piece.

Furthermore, a plurality of positioning pieces are arranged on one end face, close to the brake block, of the magnetic attraction piece, and when the brake block is in a retracted state, the end parts of the positioning pieces abut against the brake block, so that the brake block is kept parallel to a main optical axis of the light beam. The brake pads are prevented from partially entering the range of motion of the effect element during stage light operation and being susceptible to contact with the effect element and thereby to sliding.

Furthermore, the reset piece is an elastic piece and is positioned between the brake piece and the magnetic attraction piece, one end of the reset piece abuts against the brake piece, and the other end of the reset piece abuts against the magnetic attraction piece. When the magnetic attraction piece is powered off, the brake piece moves in the direction close to the effect component by utilizing the elasticity of the reset piece.

Further, the effect component is a focusing lens component or an amplifying lens component. When the effect component is a focusing lens, the focusing lens moves back and forth along the main optical axis of the light beam to change the definition of the pattern projected by the stage lamp; when the effect component is an amplifying lens, the amplifying lens moves back and forth along the main optical axis of the light beam to change the size of the pattern projected by the stage lamp.

The magnetic attraction piece 420 capable of switching states is arranged, the brake piece 410 is attracted by magnetism to keep shrinkage, the situation that the operation of the effect component 200 is influenced is avoided, the reset piece 430 is arranged to act on the brake piece 410 to brake the effect component 200, and the state switching of the magnetic attraction piece is simple.

Preferably, the brake pad 410 is made of ferromagnetic material, the magnetic attraction piece 420 is an electromagnet, when the electromagnet is powered on, the electromagnet generates magnetism and attracts the brake pad 410 to approach, and when the electromagnet is powered off and loses magnetism, the brake pad 410 moves in a direction away from the electromagnet through the reset piece 430.
