摘要

The lamp has a housing (1), a translucent light emitting disk (3) arranged in a light emitting window (2) of the housing and a highly effective lamp such as light emitting diode arranged inside the housing. A refraction disk is arranged parallel to the light emitting disk. The gap distance space between the light emitting disk and the refraction disk is sealed opposite to the ambient air in an air tight manner. An independent claim is also included for a field bus system with a control unit.
