Estimating the term…
A device for hardening a coating on an inner wall of a conduit having an oval cross section has at least a first UV lamp, a second UV lamp, and a guide unit having a mount for each of the UV lamps. The guide unit defines the position of the UV lamps in relation to the oval cross section of the conduit, which has a first curved section, a second curved section opposite the first, and two lateral sections. To allow for universal use and the most uniform possible UV irradiation of the inner wall, a first reflector is allocated for guiding light emitted by the first UV lamp onto the first curved section, and a second reflector is allocated for guiding light emitted by the second UV lamp onto the second curved section. The first and second reflectors differ in their reflector angle and/or their coefficient of reflection.
