1. A lighting device comprising:
a housing configured to carry a linear array of light radiation sources, said housing being configured such that the housing is connectable to at least one other said housing; and a first elongated diffusive screen and a second elongated diffusive screen, each of said first and second elongated diffusive screens being arranged facing said array of light radiation sources so as to be passed through by the light radiation emitted by said array of light radiation sources, each of said first and second elongated diffusive screens having a pattern of geometric features configured to produce a radiation pattern of the light radiation emitted by said lighting device, each of the first and second elongated diffusive screens having, protruding from only a portion of an edge thereof, a grip, wherein: said housing comprises an elongated holder that slidably receives and replaceably supports each of said first and second elongated diffusive screens to enable replacement of respective ones of said first and second elongated diffusive screens with a diffusive screen having a different pattern of geometric features so as to vary the radiation pattern of the light radiation emitted by said lighting device, and said elongated holder is configured to slidably receive said first elongated diffusive screen and said second elongated diffusive screen such that said first elongated diffusive screen is insertable lengthwise with respect to the elongated holder and said second elongated diffusive screen is insertable crosswise with respect to the elongated holder, and said housing is connectable to said at least one other said housing by at least one of said first and second elongated diffusive screens. |
