Abstract

A cover member (10) for elongated lighting modules (12), e.g. LEDs (122), includes:- an elongated light-propagation body (100) having a light-radiation receiving surface (100a) and a light-radiation emitting surface (S) opposite to the light-radiation receiving surface (100a), the cover member (10) being positionable with the light-radiation receiving surface (100a) facing an elongated light-radiation emission module (12), wherein the light-propagation body (100) provides light-propagation paths for light radiation from the light-radiation receiving surface (100a) to the light-radiation emitting surface (S), wherein:- the light-propagation body (100) comprises light-diffusive material (with consequent mixing of the light that propagates along the aforesaid light-propagation paths), and- a light-obstructive barrier (200) provided at the light-radiation receiving surface (100a) leaving at least one lateral portion of the light-radiation receiving surface (100a) uncovered, so that the aforesaid light-propagation paths include tortuous light-propagation paths through said at least one side portion circumventing the light-obstructive barrier (200) .
