Abstract

A safety device adapted to be used in connection with a radiation device, comprising an enclosure (1), wherein said enclosure is provided with a single or plurality of means adapted to automatically adjust emission of radiation from a radiation source (4), and wherein said safety device further comprises an electronic driver (5) connected to said radiation source (4) and a control unit (10); wherein said radiation source comprises a printed circuit board (PCB) (15) provided with one or several visible light emitting sources (16) in combination with one or several UVC light emitting sources (17) arranged in an electrical circuit (18); and in that the plurality of means adapted to automatically adjust emission of radiation comprises any one of, or a combination of: a sensor (7) configured to detect presence of one or several moving objects, arranged in series with or interconnected (19) to said PCB (15), and further configured to provide a cut-off signal to the control unit (10) if the presence of one or several moving objects is detected; anda sensor (8) configured to measure a distance to a surface of said one or several moving objects arranged in series with or interconnected (19) to PCB (15), and further configured to provide the control unit (10) with said measured distance; and a limit switch (9) arranged in series with or interconnected (19) to said PCB (15) and further configured to provide a cutoff signal to said control unit (10) if the limit switch is altered during radiation, and wherein said control unit (10) is configured to provide a signal to a double-sided function breaker (6) when a cut-off signal is received from at least one of the sensor (7) and limit switch (9), whereby said double-sided breaker is configured to stop the incoming or outgoing power to or from the electronic driver (5).
