    摘要: A backlight unit of a liquid crystal display includes a plurality of light emitting diode packages arranged in a matrix while being spaced a uniform distance apart from each other. Each light emitting diode package includes one or more light emitting diode chips and is structured such that light generated from the light emitting chips is emitted in the horizontal direction. A reflector consists of a plurality of reflection cells connected to each other in a matrix. Each of the reflection cells of a unit size has each of the light generating packages positioned at the center thereof, and reflects the light, emitted from the light emitting diode at the center thereof in the horizontal direction, in the vertical direction.

    摘要: The LED package includes a substrate, one LED or more separated from each other by designated intervals and arranged in a line on the substrate, and a molding portion, for sealing the upper surface of the substrate including the LEDs, provided with an upper surface including two curved surfaces having circular circumferential shapes, wherein each of the curved surfaces has a curvature for totally reflecting light emitted from the LEDs. The LED package assures a sufficient optical traveling route therein without requiring a separate light guide plate, thereby emitting a white ray having uniform luminance.

    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: A multi-lens LED has multiple lenses and an intermediate layer interposed between the multiple lenses in order to radiate light emitted from an LED chip in a desired direction and/or at a desired beam angle. The first lens is centered behind the LED chip when seen in the propagation direction of light. The second lens has a concave structure and surrounds the first lens. The intermediate layer is interposed between the first and second lenses, so that light emitted from the LED chip can be radiated at a wide beam angle. When provided in the form of a hemisphere, the multi-lens LED can be attached, e.g., to a wall or a ceiling for interior lighting. On the other hand, when provided in the form of a semicylinder, the multi-lens LEDs can be arranged in arrays to be used, e.g., as a light source of an LCD backlight apparatus.
