Abstract:
A flexible printed circuit is described that includes a flexible supporting substrate having a first face and a second face. A conductive material is deposited by vacuum deposition on at least one of the first face or the second face of the flexible supporting substrate. A flexible conductive circuit is formed on the conductive material by electrical discharge machining. The flexible conductive circuit defines a plurality of electrical component placement circuits to which electrical components may be attached. The flexible printed circuit can be rolled or folded. The flexible printed circuit can also be made in sizes much larger than is currently possible with other competing technologies.
Abstract:
There is provided a carrier (6) for solid-state lighting devices (2). The carrier (6) is intended to be arranged in a light bulb and is formed from one single flat and formable substrate (1), which has been bent to a generally tube-shaped form. The carrier (6) includes: an annular mounting portion (4) for mounting the carrier (6) inside the light bulb; and two or more strips (5) extending generally parallel to each other from the annular mounting portion (4) and being separated from each other in a tangential direction of the annular mounting portion (4). Each strip (5) has one or more electrically conducting paths (3) and a solid-state lighting device (2) mounted thereon. There is also provided a method for producing a tube- shaped carrier (6). The strips are easy to shape by bending, twisting and/or folding, resulting in a significant freedom in the positioning of the SSL devices
