In the article UV lacquer products were presented, general rules of their hardening, mercury (Hg), gallium (Ga) and UV-LED radiators were characterized, accenting among other things energy matters determining important positions in the structure of costs of presented technology. UV LED radiators with reference to conventional systems need considerably higher investment costs. However thanks to the longer life time, the low application on the energy, to the safety for health of workers overlooking work of equipments and requirements from the range of the environmental protection merit the wide promotion and the successive initiation to the industrial practice in different scopes of woodworking industry. In comparison to existing solutions with the use of conventional UV radiators obtained lacquer coatings are characterized the decidedness with higher parameters within the range especially resistances on various factors.
