Description

Technical Field

[0001] This utility model belongs to the field of stage lighting technology, specifically relating to a combined lens disk and stage lighting fixture for multi-source LED stage lights. Background Technology

[0002] LED light sources, as a crucial element of stage lighting, are widely used due to their high luminous efficiency, excellent combined rendering effects, energy saving, environmental friendliness, and long lifespan. In recent years, multi-light source combination zoom LED stage lights have emerged. The most distinctive feature of these lights is that their light source modules are encapsulated and integrated with multiple multi-color (including Red, Green, Blue, and White) LED beads. Each light source has its own independent light guide system and light emission aperture. Each LED bead in the light source module can be individually controlled in single color, or the entire module can be controlled. Furthermore, functions such as beam zooming and beam rotation / deflection allow for the concentrated emission of rich and varied lighting effects from the lamp head, making them highly popular in the market. LED stage lights are now widely used in theaters, television stations, bars, theme parks, and many other fields.

[0003] The biggest drawback of this type of lamp is that it has a relatively large number of lenses, making the assembly, cleaning, and maintenance of the lens panel more troublesome; in addition, there is light leakage or crosstalk between individual lenses, which will affect the lamp's light efficiency. Summary of the Invention

[0004] To address the problems in related technologies, this utility model proposes a combined lens disk and stage lighting fixture for multi-source LED stage lights. By utilizing the structure of peripheral lenses and central lenses, a large number of lenses are integrated, which facilitates the installation and cleaning of the lens disk. The design of the boss and lens break prevents light leakage and crosstalk between lenses.

[0005] This utility model is implemented as follows:
