Abstract (en)
Flush-mounted LED lighting device (1) for signalling the presence or direction of stairs, steps and raised floors, comprises a casing (2) with abutment, a diffuser (10), housed inside the casing (2), made in colourless or coloured material transparent to the light. A cavity (14) is formed between the diffuser (10) and the casing. The LED light source (20) is positioned inside the diffuser (10). In addition, a plug (40) opaque to the light, is positioned at the top of the diffuser (10) and forms a free gap (50) with the casing, so that the cavity (14) is permanently in communication with the outside environment and the light is emitted in the shape of an aureole.
