    摘要： The invention relates to an LED package having a large beam angle of light emitted from an LED, simplifying a shape of a lens and an assembly process, and to a backlight unit using the same. The LED package includes a housing with a seating recess formed therein and at least one LED seated in the seating recess. The LED package also includes a lens having a predetermined sag on an upper side thereof, covering an upper part of the LED. The LED package and the backlight unit using the same can emit light uniformly without bright spots formed in an output screen, uses a simpler shaped lens with an increased beam angle, and minimizes a color mixing region to achieve miniaturization.

    摘要： A Chip on Board (COB) package which can reduce the manufacturing costs by using a general PCB as a substrate, increase a heat radiation effect from a light source, thereby realizing a high quality light source at low costs, and a manufacturing method thereof. The COB package includes a board-like substrate with a circuit printed on a surface thereof, the substrate having a through hole. The package also includes a light source positioned in the through hole and including a submount and a dome structure made of resin, covering and fixing the light source to the substrate. The invention allows a good heat radiation effect by using the general PCB as the substrate, enabling manufacture of a high quality COB package at low costs. This in turn improves emission efficiency of the light source, ultimately realizing a high quality light source.

    摘要： An LED package and a fabrication method therefor. The LED package includes first and second lead frames made of heat and electric conductors, each of the lead frames comprising a planar base and extensions extending in opposed directions and upward directions from the base. The package also includes a package body made of a resin and configured to surround the extensions of the first and second lead frames to fix the first and second lead frames while exposing underside surfaces of the first and second lead frames. The LED package further includes a light emitting diode chip disposed on an upper surface of the base of the first lead frame and electrically connected to the bases of the first and second lead frames, and a transparent encapsulant for encapsulating the light emitting diode chip.

    摘要： Provided are a method of and apparatus for lossless video encoding and decoding, in which a differential residual block generated by calculating a difference between pixels of a residual block resulting from interprediction is encoded, thereby improving the compression rate. The method of lossless video encoding includes performing interprediction between a reference frame and a current frame in units of a predetermined-size block to generate a predicted block of a current block to be encoded, generating a residual block composed of residual signals corresponding to differences between pixels of the predicted block and the current block, calculating differences between the residual signals of the residual block in a predetermined direction and generating a differential residual block based on the calculated differences, and performing entropy-encoding on the differential residual block.

    摘要： An LED diode package includes a heat connecting part for mounting a light emitting part on an upper surface thereof, frames electrically connected to the light emitting part while holding the heat connecting part and a molded part fixing the heat connecting part and the frames together. The light emitting part generates light in response to current applied thereto, and the upper surface of the heat connecting part is protruded beyond an upper surface of the molded part to a predetermined height. This can optimize the unique beam angle of the light source thereby to maximize lighting efficiency as well as prevent overflow of the encapsulating material in the assembling process of the lens, which may otherwise soil adjacent components.
