    摘要: The present invention relates to an LED lens, in which a planar bottom has a pair of halves symmetrically connected with each other about a reference line and narrowed in the vicinity of the reference line. A pair of substantially semicircular reflecting surfaces are extended from both edges of the bottom connected with both ends of the reference line. A radiating surface is connected with remaining edges of the bottom and semicircular edges of the reflecting surfaces. The reflecting surfaces reflect light beams are introduced from the LED chip through the bottom toward the radiating surface. The radiating surface radiates the light beams to the outside when the light beams are introduced to the radiating surface through reflection from the reflecting surfaces and directly through the bottom, so that the light beams are radiated to the outside in a predetermined beam angle.

    摘要: A direct-illumination backlight apparatus uses LEDs as a light source. This backlight apparatus comprises: a flat reflective plate; an LED light source arranged on the reflective plate; a transparent plate arranged above the LED light source; a scattering pattern arranged on an underside of the transparent plate in a position corresponding to the LED light source; and a light guide made of transparent material, and arranged around the scattering pattern to introduce light incident from below into the transparent plate so that the light is internally reflected by the transparent plate. The light guide serves to introduce a partial light from an LED light source at such an angle that the partial light is trapped inside the transparent plate, and the scattering pattern serves to scatter the trapped light beam at a position directly above the LED light source so that the scattered light beam escapes out of the transparent plate toward an LCD panel. This can remove any dark area above the LED light source in the transparent plate and thus reduce the thickness of the direct-illumination backlight apparatus.

    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: This invention relates to an LED backlight apparatus. The LED backlight apparatus comprises: a housing having an upper opening; a reflective sheet provided on a bottom inside the housing; a plurality of LED light sources arranged above the reflective sheet at a predetermined distance to emit light toward the reflective sheet; and a light source support connected to a side wall of the housing to support the LED light sources. The light sources are arranged opposite to the reflective sheet so that light beams emitted from the LED light sources reflect from the reflective sheet before entering a diffuser plate behind the LED light sources from the reflective sheet, thereby potentially reducing the thickness of the backlight apparatus while ensuring a distance for the light beams to sufficiently mix together before entering the differ plate.

    摘要: The present invention relates to a backlight apparatus used in an LCD, in which upper and lower reflective plates are installed under upper and lower transparent plates, respectively. The lower transparent plates and the lower reflective plates introduce light generated by lower light sources in upward directions and the upper transparent plate and the upper reflective plates introduce light generated by an upper light source into those areas, which are not lighted by the lower light sources. This can prevent the formation of dark areas above the lower light sources as a problem of a conventional large-sized backlight apparatus, thereby enhancing the overall uniformity of light. In this way, the backlight apparatus of the invention can be designed thin even when applied to a large-sized LCD.

    摘要: The invention relates to an LCD backlight apparatus, which 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 in 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 an LCD.

    摘要: The present invention relates to a multi-lens LED. The 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 beam angle without using a complicated lens configuration. 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, and the intermediate layer is interposed between the first and second lenses, so that light emitted from the LED chip can be radiated in a wide beam angle. When provided in the form of a hemisphere, the multi-lens LED can be attached to a wall or a ceiling in use for interior lighting. On the other hand, when provided in the form of a cylinder, the multi-lens LED of the invention can be applied in arrays to be used as a light source of an LCD backlight apparatus.
