A method for producing, by a laser that scans the rear side of a transparent object, figures and text that are recessed in the transparent material and that as seen from the outside (5) appear as a raised relief (1) and for which the effect of depth (d, d′) depends on the amplitude of a signal superposed the input, frequency-controlled laser power by which the screen pattern is obtained. By an optimal fineness of scanning relative the material of the sign, the figures may obtain a very strong luminescence even at a very low input edge-illumination power. Furthermore, the invention relates to an edge-illuminated electric sign (L1, L2) with a figure produced by the manufacturing method according to the invention. Furthermore, the invention relates to a mounting system in the form of two interacting moulding strips (3, 4) for mounting one or more electric signs (L1, L2) manufactured according to the invention.

A manufacturing method for production of an edge-illuminated sign with one or more figures having a large relief effect and a strong luminescence, the method comprising controlling a laser beam using a master program that makes the laser beam scan a line pattern at the same time as the laser beam is modulated by a frequency that controls the amplitude of the input power to the laser and thereby creates a screen pattern at the same time as an image program is superposed the amplitude-controlled scanning frequency, so that the input laser power with amplitude variations proportional to the desired figure will burn at different depths and thereby give a relief of the figure, in the sign.
An edge-illuminated electric sign comprising a figure that is luminous when illuminated, wherein the figure has been applied to the electric sign by a manufacturing method comprising controlling a laser beam using a master program that makes the laser beam scan a line pattern at the same time as the laser beam is modulated by a frequency that controls the amplitude of the input power to the laser and thereby creates a screen pattern at the same time as an image program is superposed the amplitude-controlled scanning frequency, so that the input laser power with amplitude variations proportional to the desired figure will bum at different depths and thereby give a relief of the figure, in the sign.
An edge-illuminated electric sign comprising a film or foil with a screen pattern, in which the screen pattern has a fineness proportional to the luminescence desired in different positions of the background and that the fineness is also proportional to the distance to the illuminated edge, the screen pattern being produced by controlling a laser beam using a master program that makes the laser beam scan a line pattern at the same time as the laser beam is modulated by a frequency that controls the amplitude of the input power to the laser and thereby creates a screen pattern at the same time as an image program is superposed the amplitude-controlled scanning frequency, so that the input laser power with amplitude variations proportional to the desired figure will burn at different depths and thereby give a relief of the figure, in the sign.
