Abstract:
The invention relates to an LED light source on which a plurality of LED chips (11) is fixed and is electrically connected in series via e.g. soldered joints (25, 18). The invention also relates to LED chips (11) which are suitable to be mounted on the respective substrate (19). The contacting of adjacent LED chips (11) is ensured by their overlap in a region (15), thereby eliminating the need for providing interspaced between the adjacent LED chips for the purpose of their electrical connection as is the case for conventional LED chips. The advantage of the overlapping arrangement is that a high packing density of LED chips can be achieved, thereby making it possible for the LED light source to emit a comparatively homogeneous light field having a comparatively high intensity.
Abstract:
A printed circuit assembly (10) includes a base printed circuit (12) having a printed circuit receiving area (29) and a plurality of electrical contacts provided on the printed circuit receiving area (30). The printed circuit assembly also includes a secondary printed circuit (14) having a secondary substrate (54) including a mating edge (46) and a plurality of secondary contacts (70) provided along the mating edge. The secondary printed circuit is mounted on the base printed circuit such that the mating edge of the secondary printed circuit is directly engaged with the base printed circuit at the printed circuit receiving area. Each of the secondary contacts is electrically connected to a corresponding one of the electrical contacts of the base printed circuit.

A supporting component (1) adapted for being mounted on a substrate (11) and for serving as a support for a surface mounted device (15) comprises a body (2) having a first surface (3) adapted for being mounted on the substrate (11), and a second surface (4) being adapted for supporting the surface mounted device (15). The second surface (4) is inclined in relation to the first surface (3). The supporting component (1) further comprises a first supporting component conductor (6) adapted for forming an electrical contact between a first substrate conductor (12) of the substrate (11) and a first electrode (16) of the surface mounted device (15). In a method of mounting a surface mounted device (15) in an inclined manner on a substrate (11) the supporting component (1) is mounted on the substrate (11) with the surface mounted device (15) on top of it.

Abstract:
An electronic device packaging structure is described wherein an electronic device (40) is electrically connected to a substrate (44) wherein the electronic device subtends a non-normal angle with respect to the substrate. In a more specific embodiment, a plurality of electronic devices (40) are stacked at offset with respect to each other to expose contact locations on the surface of each electronic device at an edge of each electronic device to form a stepped surface exposing a plurality of electronic device contact locations. This surface is disposed against a substrate having a plurality of contact locations (46) thereon. The electronic device contact locations can be electrically interconnected to the substrate contact locations by solder mounds (48) or alternatively by a cylindrical shaped elastomeric body having metallization bands with a spacing corresponding to the electronic device contact locations. The elastomeric body is pressed between the edge of the stacked electronic devices having the contact locations thereon and substrate surface to form electrical interconnections between electronic device contact locations and substrate contact locations through the electrically conducting bands. The stacked electronic devices can be thermally connected to a heat dissipation means. The stacked electronic devices can have a stepped surface (34) embodying an enhanced area for transfer of heat from the electronic device stack to the heat dissipation means (50).

Les pièces (2, 4) sont munies de plots (6, 8, 10, 12) destinés à être reliés au moyen d'éléments de soudure faits d'un matériau métallique à bas point de fusion, soudable aux plots, la surface de chaque plot étant mouillable par le matériau à l'état fondu alors que son environnement ne l'est pas. Les plots de l'une des pièces sont recouverts de galettes (10, 12) du matériau, de même épaisseur mais de volumes différents ; les plots de l'autre pièce sont placés sur les galettes correspondantes les galettes sont portées à l'état fondu, leur épaisseur, leurs volumes, leur écartement et les surfaces des plots étant choisis pour que les pièces fassent alors entre elles un angle déterminé. Application à la fabrication de miroirs.
Abstract:
A light emitting unit and an illumination apparatus are provided to acquire a minimized space requested for an operation by extending an end point of at least lead terminal along an inclined direction, thereby limiting dead space and reducing a size and weight of a product. A light emitting unit comprises the followings: a light emitting element(15a,15b,15c); multiple lead frames(11,12a,12b,12c) to which the light emitting element is electrically connected; and a package(13), in which the lead frame is projected in an end point, having a light emitting window for outputting light from the light emitting element. The end point of the lead frame is inclined from the light emitting window. The other part of the lead frame is projected. A surface size of the other part of the lead frame is bigger than that of the end point of the lead frame.
