Abstract
Optical systems for linear lighting, particularly linear lighting that is installed in a channel, are disclosed, as are light fixtures that use these optical systems. The optical systems have multiple lenses, usually a first lens adapted to be positioned close to a strip of linear lighting installed in a channel, and a second lens adapted to be positioned farther from the strip of linear lighting. The two lenses are optically aligned with one another such that light from the first lens reaches the second lens. The two lenses may, e.g., form an Abbe condenser lens system. In some embodiments, diffusing features may be integrated into one or both lenses to effect light mixing. The multiple lenses may be adapted to physically support one another, and to engage with structure provided by the channel for securing a cover.
