Title:
OPTICAL SYSTEM AND LIGHTING FIXTURE USING OPTICAL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/210565
Kind Code:
A1
Abstract:
An optical system and a lighting fixture using the optical system, said optical system comprising a substrate, a light source, a light guide body and an optical lens, wherein the light source is mounted on the substrate, and the light source comprises a plurality of sets of light-emitting arrays. Each set of light-emitting arrays is correspondingly provided with a light guide body, and the light guide bodies comprise incident surfaces, light guide surfaces and output surfaces, wherein light emitted by the light-emitting arrays enters by means of the incident surfaces of the light guide bodies, is uniformly processed by the light guide surfaces, and then is outputted from the output surfaces; and light exiting from the light guide bodies traverses the optical lens to form a light beam and exits. The optical system further comprises a honeycomb cover, said honeycomb cover comprising a plurality of through holes, and said through holes being sleeved on a lens of the optical lens; the cross section of the through holes matches the maximum cross sectional dimensions of the lens of the optical lens; the overall shape of the through holes arrayed on the honeycomb cover matches the overall shape of the light source arrayed on the substrate. By means of the described technical solution, a string of lights may be effectively avoided while ensuring the uniformity of light spots.
