The invention provides a method for 3D printing a 3D item, the method comprising providing 3D printable material () and printing during a printing stage said 3D printable material (), wherein the 3D printable material () comprises a thermoplastic material, to provide said 3D item, wherein the 3D item comprises an item surface, wherein the method further comprises providing a powder coating with a powder coating device () on at least part of said item surface during a coating stage. The invention also relates to the item manufactured by such method and to the manufacturing apparatus () used.

Power coated FDM printed item, related manufacturing method and apparatus

The invention provides a light generating system () comprising a LED module (), a module support (), and a connector element (), wherein: the module support () comprises a first module support opening () for hosting at least part of a first connector element part (); the LED module () comprises a LED support () and a plurality of LEDs () functionally coupled to the LED support (), wherein the LED support () comprises a LED support opening () for hosting at least part of the first connector element part (); and wherein the plurality of LEDs () are configured to generate light source light (); the connector element () comprises the first connector element part (), and wherein the first connector element part () comprises a first spring part (); at least part of the first connector element part () penetrates through the first module support opening); and the LED support opening (), the first connector element part (), and the module support () are chosen such that in a functional coupling of the LED module () and the module support (), at least part of the first connector element part () penetrates through the LED support opening (), and the first spring part () exerts a force on the LED module () against the module support ().

Lamp or luminaire comprising a LED module

An OLED lighting module comprising a support (); an OLED lighting panel () with an emissive side with emissive and non-emissive areas () and an opposite side which comprises an OLED substrate (), an OLED light-generating unit and a circuit board (); an opaque liner with a first section () that covers at least part of the non-emitting areas () over the OLED substrate and a second section () that extend past the edges of the OLED substrate on the emissive side of the OLED panel; and an opaque bezel () in contact with the support (), the opaque bezel () covering at least part of the second section () of the opaque liner but not the first section () of the opaque liner. By covering only that portion of an opaque liner that extends past the edges of the OLED substrate with a bezel and not the OLED substrate itself, the module can be made thin.
