STAGE LAMP OPTICAL SYSTEM WITH IMPROVED LIGHT SPOT HOMOGENEITY

摘要

A stage lamp optical system with improved light spot homogeneity comprises a light source and a light-reflecting cup (1) which are sequentially arranged along the main optical axis. The stage lamp optical system further comprises a first optical assembly (2) arranged between the first focus F1 and the second focus F2 of the light-reflecting cup (1). The first optical assembly (2) is a single lens array, a combination of array lenses and lenses, or a combination of array lenses. It splits the whole optical beam into narrow optical beams and superposes the narrow optical beams again, and light energy is utilized effectively and evenly, and therefore the light spot homogeneity is improved.
