A LIGHTING ELEMENT, A LIGHTING SYSTEM AND A LUMINAIRE PROVIDING A SKYLIGHT APPEARANCE

摘要

A lighting element (100), a lighting system and a luminaire are provided. The lighting element (100) is used for obtaining a skylight appearance and comprises a white light emitting means (104) for emitting white light, a blue light emitting means 106 for emitting blue light and a Fresnel lens (102). The Fresnel lens (102) is arranged to receive light from the white light emitting means (104) and from the blue light emitting means (106). The white light emitting means (104) is arranged in a first relative position with respect to the Fresnel lens (102) to collimate at least a part of the light emitted by the white light emitting means (104) to obtain a collimated directed light beam in a specific direction. The blue light emitting means (106) is arranged in a second relative position with respect to the Fresnel lens (102) to obtain a blue light emission at least outside the collimated directed light beam.
