摘要： The invention provides a method wherein 3D printed layers are stacked, but wherein at one or more positions one layer is shifted sideways relative to the other. It looks like a (small) excursion. Hence, the one layer deviates sideways from the layer below and returns back on the layer below. This may be over a relatively small length. The excursion is chosen such, that there is an opening between the lower layer and the layer that deviates sideways. In this way, a 3D printed item comprising a stack of layers may have (physical) openings, which allow transmission of light. In general, the layer height of the layers is not adapted. The deviations or excursions may be provided in a regular way. This provides a 3D printed with a regular arrangement of openings Note that not each layer of the 3D printed item necessarily includes such deviations or excursions.

摘要： The present disclosure relates to a LED filament system (100) comprising a LED filament arrangement (105) and a controller (120). The LED filament arrangement comprises a plurality of LED filaments (110a-c). The LED filaments are interwound around a common central axis (A) such that each LED filament has a spiral-shape. In the LED filament arrangement, two neighboring LED filaments differ by a translation pitch (t) along the central axis. The controller is configured to control power supply to the LED filaments such that at least one of the plurality of LED filaments is individually controllable. The controller is further configured to control the power supply to the LED filaments in a first mode, in which all of the LED filaments are in an on-state and the controller provides power supply above a first power level to the LED filaments. The controller is further configured to control the power supply to the LED filaments in a second mode in which at least one of the LED filaments is in an off-state.

摘要： A luminaire (10) has first light source (30) which provides light into a light mixing chamber (20) such that un-collimated light reaches the light output face (26) of the light mixing chamber (20), and a second light source (32) which provides collimated light to the light output face (26). The luminaire (10) can thus produce a diffuse flat light output and/or a directed partially collimated light output for example for task lighting.
