1. A lighting panel system comprising:
a luminous panel comprising an array of LED nodes, each LED node of the array of LED nodes comprising one or more LEDs, each of the one or more LEDs comprising a light exit surface and being configured to, in operation, emit light, one or more first subsets of the array of LED nodes being spotlight nodes comprising collimating secondary optics, and one or more second subsets of the array of LED nodes being regular LED nodes not comprising collimating secondary optics, and
a grid structure arranged such that the light emitted by the LEDs of the array of LED nodes traverses the grid structure, wherein
the grid structure comprises at least one of a diffusely reflecting and a diffusely transmissive surface part,
the grid structure is constructed such as to allow one or more pre-defined beam angles of light emitted by the LEDs of the spotlight nodes to pass without being reflected by the grid structure,
the grid structure is configured and arranged to hide the collimating secondary optics of the spotlight nodes when seen from the point of view of a viewer looking at the lighting panel system, and
wherein the grid structure is a linear grid comprising a plurality of grid elements, and wherein the plurality of grid elements are aligned along a direction being any one of not parallel with and perpendicular to the light exit surface of each LED of the array of LED nodes.
