  • LIGHTING DEVICE TO SIMULATE NATURAL LIGHT
    Publication number: 20230341107
    Abstract: The present invention relates in general terms to a lighting device to simulate natural lighting, thus capable of generating at least two light components with different angular distributions having different correlated colour temperature or CCT. The lighting device to simulate natural lighting thus conceived is able to generate a light with two chromatic components having different angular distributions, however effectively preventing the light at a higher colour temperature (bluish light) from generating glare effects or from giving the environment an unnatural colouring that the natural light of the sky and the sun would not produce.

  • SUN-SKY-IMITATING ILLUMINATION DEVICE
    Publication number: 20220357017
    Abstract: The present disclosure is directed to a sun-sky-imitating illumination device (100) for generating natural light similar to that from the sun and the sky, comprising a direct-light generator (10) that comprises a first emitting surface (11) from which a direct light (13) is emitted and a collimated light source (20) configured to generate from a primary light a collimated light (23) which exits an output surface (22) positioned upstream from the first emitting surface (11) with respect to a direct light direction (15), wherein the direct light (13) has a luminance profile (Ldirect(x, y, ?, ?)) which has a first peak in the angular distribution around the direct-light direction (15) and the collimated light (23) exiting the output surface (22) has a luminance profile (Lcoll(x, y, ?, ?)) which has a second peak (14) in the angular distribution around the direct-light direction (15), the second peak being a narrow peak, and a diffused-light generator (50) that is at least partially light-transparent and is posit
