Projection lamp for dancing theater and using method

Abstract

The invention discloses a projection lamp for a dancing theater and a using method. The projection lamp comprises a chassis; the bottom of an inner cavity of the chassis is movably connected with a first electric telescopic rod; the top of the first electric telescopic rod extends to the top of the chassis; the end, located in the inner cavity of the chassis, of the first electric telescopic rod is fixedly sleeved with a straight gear; and the rear side of the inner cavity of the chassis is fixedly connected with a second electric telescopic rod. The height and angle of the projection lamp canbe adjusted conveniently, so that the projection position of the projection lamp is convenient to adjust, and different images can be projected; projection effect is good, heat dissipation effect isgood, and the service life is long; and the problems that an existing dancing theater projection lamp is simple in structure, the height and angle of the projection lamp are inconvenient to adjust, the projection position of the projection lamp is inconvenient to adjust, no external imaging structure exists, different images cannot be projected, the projection effect is reduced, the heat dissipation effect is poor, and the service life is shortened are solved.

Description

technical field [0001] The invention relates to the technical field of projection lamps, in particular to a projection lamp used in a dance theater and a usage method. Background technique [0002] Stage lighting is also called "stage lighting", referred to as "lighting", one of the means of stage art modeling, using stage lighting equipment (such as lighting fixtures, slides, control systems, etc.) Its changes show the environment, render the atmosphere, highlight the central figure, create a sense of stage space and time, shape the external image of the stage performance, and provide the necessary lighting effects (such as wind, rain, cloud, water, lightning). Stage lighting is The important part of the performance space is to carry out the lighting design of the all-round visual stage lighting environment for the characters and the specific scenes required according to the development of the plot, and purposely reproduce the design intention to the audience in the form of...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a projection lamp for dance theater and its use method, which is convenient for adjusting the height and angle of the projection lamp, and for adjusting the projection position of the projection lamp, and can project different images, with good projection effect and good heat dissipation effect , the advantage of long service life solves the problem that the existing dance theater projection lamp has a simple structure and is inconvenient to adjust the height and angle of the projection lamp, so that it is not convenient to adjust the projection position of the projection lamp. There is no external imaging structure, and different images cannot be projected , reduces the projection effect, poor heat dissipation, and reduces the problem of its own service life
