<p>The device (1) has a rectangular plate (3) with a profile and made of a luminescent material. A light source e.g. cold cathode fluorescent lamp, is provided along a narrow side (3a) of the plate for constant lighting of the plate. The plate is formed in such a manner that the entire region of the plate admits the light generated by the light source. The light source is attached to the narrow side of the plate and on a signboard (2) that is made of plastic. An independent claim is also included for a light with a cold cathode fluorescent lamp and a control block for a device for signaling an emergency exit in a tunnel.</p> |
