    Abstract: The invention provides a method for manufacturing a 3D item by means of 3D printing using a 3D printer with a build platform and an extrusion head comprising a nozzle. The method comprises the steps of (i) providing a 3D-printable material to the extrusion head; (ii) extruding the 3D-printable material through the nozzle at a material flow rate; and (iii) depositing the 3D-printable material along a tool path on a substrate while moving at least one of the extrusion head and the build platform at a tool path speed thereby forming a stack of layers (411, 412) that have been deposited on top of each other. The material flow rate and the tool path speed are controllable, and the tool path speed is successively varied between a minimum value and a maximum value while the material flow rate is kept substantially constant in such a way that each layer (411, 412) of the stack of layers (411, 412) has a layer width that successively varies between a minimum layer width and a maximum layer width, the ratio of the minimum layer width and the maximum layer width being 0.9 or less. The method of the invention results in a 3D item that has a particular surface texture on at least one of the inner and outer surfaces of a wall of the 3D item, wherein the surface texture is decorative and, dependent on the 3D-printable material, may also have an additional optical functionality.

    Abstract: The invention relates to computer implemented method that enables the generation of a virtual design of a lighting device and that determines the components for the virtually designed lighting device. The computer implemented method comprises four main steps and will be performed on a computing device or system. First 100, the computing device receives desired lighting output information indicative of a desired lighting output. Then 102, it selects an initial virtual lighting device able to generate the desired lighting output. Subsequently 104, it adapts parameters of the initial virtual lighting device for generating the virtual design of the lighting device while retaining the desired lighting output. Finally 106, the components 802-810, 814, 816 for the virtually designed lighting device are determined based on the virtual design of the lighting device and on the desired lighting output information, wherein the step of determining the components comprises: determining 600 a number of lumens based on the desired lighting output, determining 602 a number of light emitters and a type of the light emitters 802 based on the number of lumens and based on the desired lighting output and determining 604 a number of drivers and a type of the drivers 810 based on the number and type of light emitters.

    Abstract: A luminaire for identifying a lamp shade is disclosed. The luminaire comprises a light source (102), a lamp shade (104) and a second luminaire component (108). The lamp shade (104) comprises at least one surface feature (106) which comprises an identifier, the identifier being representative of at least one characteristic of the lamp shade (104). The second luminaire component (108) comprises a detector (110) arranged for detecting the at least (5) one surface feature (106) of the lamp shade (104). The second luminaire component (108) further comprises a first processor (112) arranged for retrieving the identifier from the detected at least one surface feature (106), and for identifying the at least one characteristic of the lamp shade (104) based on the retrieved identifier. This allows the second luminaire component (108) to control, for example, the light output of the light source (102) based on the identified at least (10) one characteristic, or to transmit the retrieved information to a further device for further control or for informative purposes.
