    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.

    摘要: An LED package comprises a substrate, one or three terminals formed on a first side of the substrate, three terminals formed on a second side opposite to the first side, and two or three LEDs disposed on the substrate, one of the LEDS being electrically connected to one of the terminals formed on the first side while being electrically connected to one of the terminals formed on the second side, and other LEDS being electrically connected to two terminals formed on the first side or to two terminals formed on the second side. A light source comprises the LED packages having the structure as described above. Without being arranged in a line, the LEDs emitting the same color are differently arranged in every LED package, thereby solving the problem of non-uniform combination of the colors according to the positions of the LEDs on an LED package-mounting substrate.

    摘要: Disclosed herein is a light emitting diode (LED) device. The light emitting diode device comprises a package formed with a terminal for applying an electrical signal, one or more LED chips mounted on the package such that the LED chips are electrically connected to the terminal, a lens formed to surround the LED chips on the package for changing path of light emitted from the LED chips to the horizontal direction with the difference of the refraction rates of the media, and a reflector formed on the lens for reflecting the light, emitted above the lens without being refracted in the horizontal direction at the lens, to the horizontal direction. The LED device reflects the light, which is deviated from the optical design range of the lens and emitted above the lens, back to the lens, thereby preventing the hot spot from being generated, and enhancing horizontal emission efficiency of the light.
