Document Type and Number:
WIPO Patent Application WO/2017/067515
Kind Code:

Abstract:
A lens set, and lighting device employing a lens set. The lens set (30) is configured to at least accommodate a first light source (42) and a second light source (43), and comprises a first lens (32) and a second lens (31). The first lens (32) comprises a first light incoming surface (322), a first light exit surface (324), and a first accommodation space (321) located at a side of the first light incoming surface (322) and configured to accommodate the first light source (42). The second lens (31) comprises a second light incoming surface (312), a second light exit surface (314), and a second accommodation space (311) located at a side of the second light incoming surface (312) and configured to accommodate the second light source (43). A light exit pattern of light emitted by the first light source (42) and passing through the first light incoming surface (322) and the first light exit surface (324) is consistent with a light exit pattern of light emitted by the second light source (43) and passing through the second light incoming surface (312) and the second light exit surface (314). The present invention addresses the problem in the existing art in which an identical light distribution effect is difficult to be ensured if different light sources emit light passing through respective lenses covering the light sources.
