摘要： An improved flat lighting device is provided. The flat lighting device comprises a light transmission member having a luminous surface formed on the front side thereof, a reflection surface on the rear side of said luminous surface, and an incident surface, and further comprises a light source and a reflecting mirror in the vicinity of the side perpendicular to said luminous surface. The thickness of the light transmission member between the luminous surface and the reflection surface is increased wider than that of the incident surface, the lower end of said incident surface is in contact with the reflection surface, said light source and said reflecting mirror are provided closer to the center of the light transmission member inside the end of the luminous surface, said inclined surface is formed by connecting the upper end of the incident surface and the end of the luminous surface, and said inclined surface is provided with a reflection function. According to the invention, the luminous surface can be more luminous owing to reflection by the inclined surface, and the flat lighting device itself can be formed so that the area is approximately equal to the display area of a liquid crystal display for lighting.

摘要： A color-mixing section R1 is constructed by allocating to each light-adjusting area one or more LEDs 311, . . . as primary light sources and color-mixing elements R1(411), . . . for guiding primary light from the LED 311, . . . to color-mix or homogenize the brightness. An available element R2 for receiving secondary light from the color-mixing elements to emit light covers the entire color-mixing elements. The LEDs 311, . . . and the color-mixing elements R1(411), . . . are not superposed onto each other.
