摘要： A plane-shaped lighting device has a light-directing plate and a light source that is placed in contact with or in the proximity of the light-incident surface of the light-directing plate, and the light source is constituted of a plurality of LED lamps each of which has an LED chip for emitting light and a semispherical lens for directing the light from the LED chip into the light-directing plate. Here, the distance from the LED chip to the top of the semispherical lens is set to be 1.8 times as long as the radius of curvature of the semispherical lens. This arrangement allows the light emitted from the LED chip to be efficiently incident on the light-incident surface of the light-directing plate, thereby improving the light-incidence efficiency to the light-directing plate. Further, the application of this plane-shaped lighting device to display devices makes it possible to improve the efficiency of light utilization, and consequently to provide thinner display devices with high visibility.

摘要翻译： 平面状的照明装置具有导光板和与该导光板的光入射面接触或接近的光源，该光源由多个LED构成 每个灯具具有用于发光的LED芯片和用于将来自LED芯片的光引导到光导板中的半球形透镜。 这里，从半导体芯片到半球形透镜的顶部的距离被设定为半球形透镜的曲率半径的1.8倍。 由此，能够将从LED芯片发出的光有效地入射到导光板的光入射面上，从而提高对光导板的光入射效率。 此外，将这种平面状照明装置应用于显示装置使得可以提高光利用的效率，并且因此提供具有高可见度的更薄的显示装置。
