Irradiation system for solariums

摘要

The device (6) has a power supply unit (7) for operating a low pressure gas-discharge lamp i.e. fluorescent lamp (5a), and a sensor device (21) e.g. ultraviolet photo diode, for detecting an ultraviolet radiation, which is radiated from the gas-discharge lamp. A control device (14) is connected with the sensor device and the power supply device, in order to control the power supply device on the basis of a signal, which is delivered to the sensor device. The power supply device includes a trigger circuit for influencing an operational current flowing through the gas-discharge lamp.
