LINEAR LIGHTING DEVICE WITH LINEAR LENS AND SIDE LIGHT DIFFUSION WINGS

Abstract

The invention relates to a linear LED lighting device comprising a linear lens (21), at least translucent, with a longitudinal axis parallel to the longitudinal axis (l) of the body (2), having an external light-emitting face (22) and an internal light-receiving face (23) from the LEDs (5), the emission face (22), viewed in cross-section, having a central part (24) of generally convex and protruding shape bordered by two flat lateral parts, each edge of the central part forming with the corresponding flat part an angle, measured outside the linear lens, less than or equal to 95°, and the reception face (23), viewed in cross-section, comprises: a central region (30) at least partially concave situated opposite the central region of the emission face to form a cavity for receiving the LEDs,two flat lateral parts substantially parallel to the flat lateral parts of the emitting face to form two lateral wings (32) for diffusing light which border the linear lens (21), each edge of the central region forming with the corresponding flat part an angle, measured inside the linear lens, greater than or equal to 100° and preferably greater than 110°.
