Abstract
A lamp glass for a motor vehicle, such as a headlamp or indicating lamp glass, is of a plastics material such as polycarbonate, and is subjected to treatment with ultraviolet radiation before a protective coating is deposited on it.
Claims5
A method for treating glasses of transparent plastics material, comprising the steps of subjecting the surface of each glass to ultraviolet radiation emitted by electrodeless lamps, subsequently depositing a protective coating thereon, further including the steps of placing the glasses on a conveyor belt, moving the belt and glasses placed thereon through a tunnel, via:
- an entry screen;
- the interior of the tunnel;
- and an exit screen, the tunnel having disposed therein the battery of electrodeless lamps, subjecting the battery of electrodeless lamps to the action of microwaves generated by a magnetron outside of the tunnel, the lamps emitting ultraviolet radiation in response thereto.
