    摘要： A side-emission type LED package is provided. The LED package includes an LED chip, a lower structure, and an upper structure. The lower structure has a lower mirror and a transparent sealing member. The lower structure supports the LED chip. The lower mirror is extended upward and outward@ from the LED chip so as to reflect light from the LED chip upward. The transparent sealing member is formed around the LED chip inside the lower mirror. The upper structure is combined to an upper portion of the lower structure so as to reflect the light reflected upward by the lower structure to a radial lateral direction. As described above, the lower structure and the upper structure are separately provided and combined with each other, whereby molding efficiency of the sealing member is improved and the side-emission type LED package can be manufactured in an easy manner.

    摘要： An LCD backlight apparatus includes a light guide plate placed under an LCD panel of the LCD to guide light to the LCD panel. The light guide plate has an even upper surface and a scattering pattern formed in a bottom surface. A plurality of monochromatic light sources are placed in line at a side of the light guide plate to radiate light along the plane direction of the light guide plate between the upper and bottom surfaces of the light guide plate. The light sources are adapted to radiate light beams at a predetermined beam angle so that the light beams reach the scattering pattern only after having propagated a predetermined reference length necessary for forming white light when mixed together. The LCD backlight apparatus can reduce the Bezel width without increasing the thickness of the LCD.

    摘要： The invention provides an LED package and a backlight device incorporating the LED lens. The LED package has a bottom surface and a light exiting surface cylindrically extended around a central axis of the package from the bottom surface. Also, a reflecting surface is positioned on an opposite side of the bottom surface and symmetrical around the central axis such that light incident from the bottom surface is reflected toward the light exiting surface. Further, a scattering area is formed on the reflecting surface. According to the invention, by applying scattering materials on the reflecting surface of the LED package, a reflecting paper does not need to be attached, thereby simplifying a process and reducing the manufacture time and cost.
