The lamp component (1) has: a source region (2) to receive a LED light source (10), a light output surface (4) to output light, a light orienting element (6) to orient the received light towards the light output surface (4), and a housing to position the light orienting element (6) with respect to the source region (2), with a housing sidewall to let light pass through it. The light orienting element (6) i) deflects a fraction of the light towards the light output surface (4) so as to produce direct light, and ii) it refracts a fraction of the light towards the at least one housing sidewall so as to produce indirect light. The light orienting element (6) is formed by a first extruded part extending in an extrusion direction. The housing is formed by a second extruded part extending in the extrusion direction.

A device for joining a lens to a housing of a lighting device of a motor vehicle, having a receptacle device for accommodating and securing the housing, a pre-centering device for aligning and clamping the lens on the housing during an alignment procedure, and having a holding device for accommodating the lens after the alignment procedure and for holding the lens during an adjustment process, wherein the holding device is releasably attached to the pre-centering device by fastening elements during the alignment operation, and wherein the pre-centering device, together with the accommodated lens and the holding device attached to the pre-centering device is movable relative to the receptacle device during the alignment procedure such that the lens and the holding device can be aligned on the housing accommodated in the receptacle device.

A method for joining a lens to a housing of a lighting device of a motor vehicle, in which the housing is accommodated and secured in a receptacle device. The method includes accommodating the lens in a pre-centering device, aligning the lens towards the housing during an alignment procedure and accommodating the lens by a holding device after the alignment procedure. The method further includes holding the lens by the holding device during a subsequent joining process, releasably attaching the holding device to the pre-centering device, aligning, via fastening elements, during the alignment procedure and moving the accommodated lens and the holding device attached to the pre-centering device relative to the receptacle device such that the lens and the holding device are aligned on the housing accommodated in the receptacle device.

A method for joining a lens with a housing of a lighting device for a motor vehicle, having the steps: positioning the housing in a receiving device of a welding device, said housing having on its underside at least one fastener for attaching the lighting device in the motor vehicle, identifying the position of the at least one fastener relative to the receiving device, calculating a correction value on the basis of the identified position of the at least one fastener, and moving the lens held in a holding device of the welding device in the direction of the housing along a travel distance and welding the lens to the housing.

A method for 3D printing an object with at least one wall (2) having a first surface and a second, opposite surface, wherein the first surface is intended to serve as an optical functional surface, wherein the wall is formed by printing one track (16) on top of another track (17). An orientation of the object during printing is selected such that the wall has a tangent (or tangent surface) non-parallel to the z-axis, such that the first surface faces away from the x-y plane and the second surface faces the x-y plane. According to the invention, the 3D object is thus oriented during printing such that the first surface, intended to be used as an optical functional surface, faces away from the x-y plane, i.e. typically away from the support or platform on which the 3D object is printed upon. By ensuring this orientation during printing, the first surface becomes smoother than the second, opposite surface of the wall.

The present invention relates to a thermoplastic resin composition, a method of preparing the same, and an injection-molded article including the same. More particularly, the present invention relates to a thermoplastic resin composition having superior vibration welding properties along with ABS-based resin-specific impact resistance, heat resistance, and the like due to inclusion of an ABS-based graft copolymer including a conjugated diene-based rubber polymer having an average particle diameter of 0.25 to 0.35 μm; a rubber-modified graft copolymer including a diene-based rubber polymer having an average particle diameter of 0.6 to 10 μm and prepared by continuous bulk polymerization; and a matrix resin, and an injection-molded article including the thermoplastic resin composition.

The disclosure provides a portable light. The portable light includes a housing having a front surface, a rear surface, and an internal space for receiving electronic components and a battery. The portable light also includes a chip-on-board (COB) assembly. The COB assembly includes a substrate, a matrix of individual light emitting diode (LED) chips mounted to the substrate, and an outer coating covering the matrix of LED chips. The front surface of the housing is curved in one direction and the COB assembly is correspondingly curved and mounted to the front surface, such that individual LED chips are positioned about the curve and orientated to direct light outwardly about the curve to provide a collective beam angle greater than 220 degrees. The portable light further includes a front lens cover to protect the COB assembly.

A vibration welding device having a mechanically coupled multiple vibrator. Within this vibration welding device, the plurality of vibration units are arranged relative to an elongated tool such that the first direction of vibrations of the individual vibration units is oriented approximately transverse to a longitudinal axis of the tool such that, during a vibration welding process, two components are weldable to each other by vibrations different than a longitudinal direction of the components.

A light assembly and method of forming light assemblies includes a flexible light layer, a thermoplastic housing, and an IMC layer. The flexible light layer has a flexible substrate, a printed circuit, and a plurality of LEDs extending outward from the flexible substrate. The IMC layer is formed opposite the flexible light layer from the thermoplastic housing and covers the LEDs. Forming may include placing the flexible light layer within a mold cavity, injecting the thermoplastic structure on one side of the flexible light layer, and injecting the IMC layer on the opposite side of the flexible light layer from the thermoplastic structure. Injecting the thermoplastic structure into the mold cavity may change the shape of the flexible light layer. Datum features of the flexible light layer may align the thermoplastic structure relative to the datum features.
