Title:
LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/036719
Kind Code:
A1
Abstract:
A lighting device. The lighting device comprises a light source system (2) and a threaded lens (4); the light source system (2) can emit monochromatic light or mixed light having first light distribution; the threaded lens (4) is arranged on a light path of light emitted by the light source system (2); the lighting device further comprises a light shaping system (3) arranged between the light source system (2) and the threaded lens (4); the light shaping system (3) is arranged at a focal point (F) of the light source system (2); the light shaping system (3) is configured to collect light beams emitted by the light source system (2) and emit second light different from first light in distribution; the threaded lens (4) is configured to collect and converge the second light emitted by the light shaping system (3) and emit the converged light. By means of the light shaping system (3) arranged at the focal point (F) of the light source system (2), light shaped and emitted by the light shaping system (3) has continuous divergence angles, and thus light spots converged and emitted by the threaded lens (4) have more uniform distribution.
