Section: claims

1. An irradiation device having a base which is pivotably connected by means of an arm to a housing in which radiation sources are accommodated and in which a radiation exit side is present, the housing, the arm and the base being collapsible to a compact unit, characterized in that the housing has two juxtaposed elongated parts accommodating radiation sources, which parts are pivotable with respect to each other about an axis at right angles to the plane through the radiation exit side and at right angles to the plane of said base when the planes through said base and through the radiation exit side are in parallel. 2. An irradiation device as claimed in claim 1, characterized in that the two parts are pivotable up to a position in which their longitudinal axes are in alignment. 3. An irradiation device as claimed in claim 1 or 2, characterized in that the two parts of the housing are pivotably secured to one end of an intermediate arm whose other end is connected to the arm secured to the base. 4. An irradiation device as claimed in claim 3, characterized in that one end of the intermediate arm is provided with a coupling member to which the two parts of the housing are pivotably secured. 5. An irradiation device as claimed in claim 3, characterized in that the intermediate arm is in the form of a combination of two elongated parallel bars whose ends remote from the parts of the housing are pivotably connected to a short pivotal bar which is pivotably secured to the top of the arm. 6. An irradiation device as claimed in claim 5, characterized in that the short pivotal bar is bridged by a gas spring whose ends are pivotably secured to the arm secured to the base and one of the parallel bars, respectively.
