摘要： The invention provides a lighting system comprising (i) a lighting device comprising a plurality of light sources for application in a horticulture production facility, wherein the light sources are configured to illuminate with horticulture light crops, wherein the lighting system further comprises (ii) a control unit configured to control the light intensity of local light at a location, wherein the local light is the sum of the horticulture light and light at the location originating from an optional other light source, and wherein the control unit is configured to prevent a change in the photosynthetic photon flux density (PPFD) of the local light at the location of on average more than 50 μmol/sec/m2 over a predetermined period of time selected from the range of equal to or smaller than 5 minutes by controlling the contribution of the horticulture light to the local light.

摘要： An optical element for use in front of a light source for obtaining a skylight appearance, and a luminaire are provided. The optical element comprising a plurality of light transmitting cells in a raster structure, a diffuser and an edge wall. A light source emits light towards the raster structure. The raster structure collimates a part of the light and transmits a further part of the light in a predetermined spectral range. White light and colored light that is transmitted by the raster structure may impinge upon the side wall of the optical element. One face of the side wall is a region of specular reflectivity and will reflect the light that impinges upon it back into the chamber that is formed by the cooperation of the raster structure, the diffuser and the edge wall. Light exits the optical element through the diffuser.
