Title:
LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/092665
Kind Code:
A1
Abstract:
A lighting device comprises a multi-color light source (1) emitting light in multiple colors, a filter (2), and an optical component (3). The filter (2) and the optical component (3) are sequentially arranged on an optical path of the multi-color light source (1). A through hole (20) is provided on the filter (2), and is smaller than a section of a light beam from the multi-color light source (1) at the through hole (20). The optical component (3) is configured to adjust the section of the light beam. The size of the through hole (20) is smaller than the section of the light beam of the multi-color light source (1) at the through hole (20); therefore, the filter (2) can block stray light in periphery of the section of the light beam, and enable the more uniform portion in the section of the light beam to pass through the through hole, thus improving a light emitting effect of the lighting device.
