Cold-weather lamp, especially for arctic regions, uses light-emitting diodes as lighting device

摘要

A light (10) has a fluorescent-lighting device in a housing, especially for use in arctic regions. Light-emitting diodes (LEDs) are used as the lighting device. A circuit is provided for switching on the LEDs as soon as an environment-parameter and/or light parameter reach a limiting value, in particular fail to reach and are additional to the fluorescent-lighting device or instead of the fluorescent-lighting device.
