Technical Field
The invention relates to a lamp, in particular to a pneumatic lifting internal rotation type stage lamp.
Background
In the stage performance process, in order to improve the stage effect, stage lamps (one or more types of light emitted by the same stage lamp) are designed to make the brightness and the illumination color of the same area of the stage different. The traditional stage lamp achieves the effect that the lamp is driven by a motor to integrally swing or rotate to complete the lighting effect, and the lamp cannot rotate in the middle without the motor.

When in use, the power supply is LED in through the power line to the LED lamp bead. When the LED lamp is used, the LED lamp is installed through the installation seat, the lamp is connected to the installation seat through the elastic connecting piece, compressed air is input into the lamp through the air inlet channel and then flows out of the air outlet channel, and airflow generated when the compressed air flows to the light source installation cavity from the middle channel drives the rotating cover to rotate, so that the rotation of the LED lamp beads is realized, and the light effect emitted from the light outlet hole is changed. Thereby the air current drive lamp that produces when compressed air flows out in from air outlet channel removes towards the direction of keeping away from the installation thereby realize the lift of lamp and change illumination effect in order to change the stage light efficiency. The lifting rod plays a guiding role. When the lamp is far away from the mounting seat, the gas supply is stopped after the lamp is far away from the mounting seat and reaches a set distance, the lamp is reset under the action of the elastic connecting piece, then the gas is filled, and the lifting and the rotation of the lamp are repeatedly carried out. The gas supply for the rotating cover and the rotation of the rotating cover are driven in the technical scheme, so that the gas path between the rotating cover and the origin is in rotating connection through the connecting seat, and the problem that the gas pipe is wound in the rotating process of the rotating cover is effectively and skillfully solved.

The LED lamp can enable the airflow entering the light source installation cavity to flow out after reaching the LED, so that the LED can be cooled when the airflow flows. If the opening direction of the port of the middle air passage at one end of the light source installation cavity faces the installation seat, a negative pressure area can be generated around the LED due to the influence of the jet flow effect, and the formation of the negative pressure area is not beneficial to the heat dissipation of the LED.
