20150312989 | SYSTEM AND DEVICE FOR DRIVING A PLURALITY OF HIGH POWERED LED UNITS - A system for driving a plurality of high powered LED units, the system comprising a single driver for providing ripple free constant direct current to a plurality of high powered LED lamp units, wherein the single driver comprises a digital controller programmable to adjust the ripple free constant direct current at every predetermined time interval based on detection and computation of the duration taken for the energy to be discharged to the LED lamp unit to adjust the ripple free constant direct current. The above system achieves a one driver to many LED lamp units such that it alleviates or eliminates the need to have a driver attached to each LED lamp unit. | 10-29-2015 |

20100307800 | Anodised Aluminum, Dielectric, and Method - The invention provides an anodised aluminium product for use in a metal core printed circuit board which in which the anodised layer forms a dielectric, and the resultant metal core printed circuit board has a sandwich structure having a thermal conductivity higher than and a thermal resistance lower than conventional metal core printed circuit boards using alternative dielectric layers, and with improved electrical insulation properties. The invention has application in manufacture of rigid and flexible printed circuit boards which have a metal substrate, manufacture of a heat conductive substrate for semiconductor devices, and electronic devices. While the use of the invention is described in relation to metal core printed circuit boards, the anodising process and anodised aluminium of the invention may have other applications beyond this technology. The invention also provides a method of manufacturing such an anodised aluminium product. | 12-09-2010 |
20100285725 | METHOD OF DEPTH ROUTING AN ELECTRONIC LAYUP AND APPARATUS FOR EFFECTING SUCH A METHOD - A method of depth routing an electronic layup comprised of a dielectric sandwiched between a metal layer and a metal substrate which is then laminated. The method involves first positioning a hardened mask so that the mask is interposed between the metal layer and at least one nozzle of a sandblasting machine, the mask having at least one aperture provided therein. Thereafter, the electronic layup is sandblasted through the at least one aperture by way of the sandblasting machine. The force, size and type of abrasive applied by the sandblasting machine are sufficient to erode the metal layer and the dielectric but not the substrate. | 11-11-2010 |
