Abstract:
Provided is a stage lighting source system with a lamp protection function. The stage lighting source system comprises a lamp, a lamp protection device and a light filter. All are arranged along a light axis sequentially. The lamp protection device comprises a non-transparent structure and a mounting component for mounting non-transparent structure. Light axis passes through the non-transparent structure. Non-transparent structure size does not affect a lamp light emitting effect in the light axis direction. Non-transparent structure fully or partially absorbs and/or reflects light energy from the light filter. The structure is easy and convenient to use, intercepts light energy reflected from the light filter by using appropriate blocking object and structure, effectively controls lamp electrode temperature within an acceptable range, and ensures lamp service life so that a flat light filter without an included angle is applied, and an ideal optical effect is realized.
