ABSTRACT:
Light systems, in particular for curing photopolymerizable plastics on fingernails, are known which have an irradiation chamber in which one or more irradiation lamps are located and having a fan for ventilating the irradiation chamber, the fan being located in a region of the housing partitioned off from the irradiation chamber. To provide a light system, in particular for irradiating artificial fingernails, that has an adequate forced ventilation of the irradiation chamber regardless of the position of the fan in the housing and regardless of the flow courses, while still being compact in structure, an air distribution chamber is provided between the irradiation chamber and the suction or compression side of the fan. The air distribution chamber is partitioned off from the irradiation chamber by a wall having air openings, and with increasing distance from the suction or compression side of the fan, the cross-sectional area for the passage of air to the air treatment chamber is greater.
