LINEAR LIGHTING DEVICE WITH LINEAR LENS AND SIDE LIGHT DIFFUSION WINGS

Abstract

The invention relates to a linear LED lighting device comprising at least one elongated body (2) delimiting, at least partially, at least one elongated linear lighting chamber (11) in which a linear light source is located, and an elongated linear cover (20) closing the lighting chamber (11). The cover (20) forms, in relation to the linear source, a linear lens (21), at least translucent, with a longitudinal axis parallel to the longitudinal axis (1) of the body (2), having an external light-emitting face (22) and an internal light-receiving face (23) from the LEDs (5), of which - the emitting face (22), viewed in cross-section, has a central convex portion bordered by two flat lateral portions, and - the receiving face (23), viewed in cross-section,comprises: - a central region, at least partially convex, situated opposite the central region of the emitting face to form an optical system ensuring concentration of a portion of the light emitted by the diodes in at least one angular sector with a value between 20° and 120°, - two flat lateral parts substantially parallel to the flat lateral parts of the emitting face to form two lateral wings (32) for light diffusion which border the linear lens (21).
