摘要： A direct-illumination backlight apparatus using LEDs includes a flat reflective plate, an LED light source, a transparent plate, a scattering pattern, and a light guide. 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.

摘要： In 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 thereby enhancing the overall uniformity of light.

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： 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： 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.
