Abstract
Channels and channel covers for linear lighting are disclosed. The channels have an upper compartment for linear lighting and a lower compartment that may be used as a raceway, to engage parts, and for rear entry of wires. Endcaps for the channels may engage the lower compartment. Cover-lenses for linear lighting channels are also disclosed. The cover-lenses may include diffusing material and implement a thickness gradient in order to maximize the amount of diffusing material where the emitted light intensity is expected to be greatest. Diverging Fresnel features may be superimposed on the thickness gradient in order to counteract any converging effect of the thickness gradient and cause emitted light to spread more evenly.
