摘要： The present invention relates to an emergency luminaire, provided with a casing through which it is attached to the ceiling or wall, exhibiting a diffuser (D) with a smooth (flat or curved) outer surface (SEx) and an inner surface on which lenses (L) defined by microstructures (Ms) have been shaped that have been calculated by means of an algorithm that determines the configuration of a plurality of sawtooth cuts, with a constant period or peak-to-valley distance from the outside to the centre on the horizontal axis (Dx), the longest edge of which makes up the active face (as0, as1, etc.) thereof, facing the LED, and the opening angle (Alfap0) of the successive sawtooth edges (as0, as1, etc.) increases progressively towards the centre of the lens, so that each ray of light of the output beam through said lenses is adjusted in the desired direction according to the light projection of the application.
