摘要： Disclosed is an improved light-emitting device for an AC power operation. A conventional light emitting device employs an AC light-emitting diode having arrays of light emitting cells connected in reverse parallel. The arrays in the prior art alternately repeat on/off in response to a phase change of an AC power source, resulting in short light emission time during a ½ cycle and the occurrence of a flicker effect. An AC light-emitting device according to the present invention employs a variety of means by which light emission time is prolonged during a ½ cycle in response to a phase change of an AC power source and a flicker effect can be reduced. For example, the means may be switching blocks respectively connected to nodes between the light emitting cells, switching blocks connected to a plurality of arrays, or a delay phosphor. Further, there is provided an AC light-emitting device, wherein a plurality of arrays having the different numbers of light emitting cells are employed to increase light emission time and to reduce a flicker effect.

摘要： A light emitting device includes a plurality of light emitting cells which are formed on a substrate and each of which has an N-type semiconductor layer and a P-type semiconductor layer located on a portion of the N-type semiconductor layer. The plurality of light emitting cells are bonded to a submount substrate. Heat generated from the light emitting cells can be easily dissipated, so that a thermal load on the light emitting device can be reduced. Since the plurality of light emitting cells are electrically connected using connection electrodes or electrode layers formed on the submount substrate, it is possible to provide light emitting cell arrays connected to each other in series. Further, it is possible to provide a light emitting device capable of being directly driven by an AC power source by connecting the serially connected light emitting cell arrays in reverse parallel to each other.

摘要： There are provided a mold for forming a molding member and a method for forming a molding member using the same. The mold includes an upper surface, and a lower surface having an outer peripheral surface and a concave surface surrounded by the outer circumference. Injection and discharge holes extend from the upper surface to the lower surface. Accordingly, after the mold and the package are coupled so that the discharge hole is directed upward, a molding member can be formed on the package by injecting the molding material through the injection hole, whereby it is possible to prevent air bubbles from being captured in the molding member.

摘要： Disclosed is a light emitting device having a plurality of light emitting cells. The light emitting device comprises a thermally conductive substrate, such as a SiC substrate, having a thermal conductivity higher than that of a sapphire substrate. The plurality of light emitting cells are connected in series on the thermally conductive substrate. Meanwhile, a semi-insulating buffer layer is interposed between the thermally conductive substrate and the light emitting cells. For example, the semi-insulating buffer layer may be formed of AlN or semi-insulating GaN. Since the thermally conductive substrate having a thermal conductivity higher than that of a sapphire substrate is employed, heat-dissipating performance can be enhanced as compared with a conventional sapphire substrate, thereby increasing the maximum light output of a light emitting device that is driven under a high voltage AC power source. In addition, since the semi-insulating buffer layer is employed, it is possible to prevent an increase in a leakage current through the thermally conductive substrate and between the light emitting cells.

摘要： A suspended semiconductor film is anchored to a substrate at at least two opposed anchor positions, and film segments are deposited on the semiconductor film adjacent to one or more of the anchor positions to apply either tensile or compressive stress to the semiconductor film between the film segments. A crystalline silicon film may be anchored to the substrate and have tensile stress applied thereto to reduce the lattice mismatch between the silicon and a silicon-germanium layer deposited onto the silicon film. By controlling the level of stress in the silicon film, the size, density and distribution of quantum dots formed in a high germanium content silicon-germanium film deposited on the silicon film can be controlled.
