Abstract

A lighting apparatus (10) with controlled light emission comprises at least one light source (15) associated to a reflecting element (11). The reflecting element (11) consists of a number of units (12) overlapping one another, each one of the said units (12) having a reflecting bottom surface (13) and an absorbing top surface (14). The units (12) belonging to the reflecting element (11) overlap each other in such a way that no light emission from the light source (15) comes out directly upwards without encountering reflecting or absorbing parts.
