Abstract
It comprises an enclosure or cell 1, in whose base 2 are incandescent lamps 3 and 4, facing the front frame 5 which covers the opening of the cell 1, the laminar filter 6 and, superposed on the latter, a sheet 7 of coloured plastic, on whose outer plane the opaque sheet 8 is applied, delimiting the numbers or letters 9, which are translucent, making it possible to see said letters or numbers 9 in the colour of the plastic when the lamps 3 and 4 are switched off and in different colours when one or other is switched on, which generated colour is enhanced and made more luminous by means of the interposed filter 6.
