    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.

    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: 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.
