Cold UV curing apparatus especially for curing lacquer layers or printing ink on heat sensitive substrates

摘要

A UV curing apparatus has a heat absorbent barrier which reflects UV radiation back to reflectors (6, 7) behind a UV light source (5).- DETAILED DESCRIPTION - An apparatus for curing a UV coating (13) comprises a barrier which has a UV reflection layer (2) for reflecting UV radiation from a light source (5) back to reflectors (6, 7) positioned behind the light source and which comprises a heat absorbent body (1) for absorbing thermal radiation from the light source. An INDEPENDENT CLAIM is also included for a similar apparatus in which UV radiation is reflected by a UV reflection layer on the light source (5) to reflectors (6, 7) positioned behind the light source and in which a heat absorbent barrier body (1) absorbs thermal radiation from the light source
