Method for drying coatings on substrates for lamps

摘要

The invention relates to a method for drying wet or moist coatings on substrates for lamps, in which at least 25%, advantageously more than 50%, of the electromagnetic energy from a thermal radiator which is supplied for drying the coatings lies in the wavelength range between 0.7 and 1.5 mum. Tubular radiators (5) are used as thermal radiators for generating the electromagnetic radiation.
