    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： In a backlight apparatus for an LCD, a plurality of bar-shaped first LED light sources are arranged on the reflective plate to laterally emit light. A plurality of light shades are arranged above the first light sources. A transparent plate is placed above the light shades. Scattering patterns are formed in the bottom of the transparent plate in positions corresponding to the light shades. A bar-shaped second LED light source is arranged at a side of the transparent plate to emit light into the transparent plate. The light source arranged at the side of the transparent plate prevents the formation of dark areas as a problem in the prior art, thereby enhancing the entire uniformity of light. Then, the backlight apparatus can be maintained thin even when applied to a large-sized LCD.
