Sheet-shaped substrate radiating unit, has channel system arranged outside of lamp space, so that lamp space remains free from cooling agent flow, and reflector formed with hollow section admitting cooling gas as part of channel system

摘要

The unit has a housing with a bar-shaped UV-lamp (12). A reflector (14) extends along the UV-lamp and limits a lamp space (22) surrounding the UV-lamp. A channel system conveys cooling agent for cooling the reflector. The channel system (20) is arranged outside of the lamp space, so that the space remains free from a cooling agent flow (24). The reflector is formed with a hollow section admitting cooling gas as a part of the system.
