ABSTRACT:
The method is for partially or completely rebuilding a damaged lens of a vehicle lamp, particularly a lens having an interior surface with a pattern of optical dispersion elements. It allows to inexpensively rebuild a lens, such as the lens of a tail lamp or signal lamp. A thermoplastic lens obtained with the present method can also be used to replace a broken glass lens of a headlamp. In the method, a patch of a flat thermoplastic material is provided to replace the damaged section of the lens or, in some cases, the whole lens. The patch is grooved to duplicate the pattern of optical dispersion elements. In case the damaged section or lens to be replaced is not flat, the patch is heat softened and shaped with the use of a mould created from the damaged section or lens. The patch is subsequently fixed to the housing. This method is simple, inexpensive and can be carried out locally whenever necessary.
