Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, in particular to a waterproof structure for stage lamps. Background Art

[0002] Stage lighting is also called "stage illumination", or "lighting" for short. It is one of the means of stage art modeling. It uses stage lighting equipment (such as lighting fixtures, slides, control systems, etc.) and technical means to display the environment, render the atmosphere, highlight the central characters with light color and its changes as the plot develops, create a sense of stage space and time, shape the external image of the stage performance, and provide necessary lighting effects (such as wind, rain, clouds, water, and lightning).

[0003] When using stage lights outdoors, light rain may not affect their use. However, when heavy rain or rainstorms occur, the stage lights must basically be powered off and stopped from use. This is because the stage lights themselves have waterproof grade requirements. However, when heavy rain or rainstorms occur, the stage lights cannot be covered in time, and a large amount of water may enter through the heat dissipation holes, greatly increasing the probability of damage to the stage lights.
