Abstract: The present invention relates to a United Reflection Lights with Light-Emitting Diode (LED). In accordance with the present invention, the United Reflection Lights with LED consists of a housing; LED light sources which are installed with an inclination angle to the opposite inside wall of the housing and emit rays in forms of dots to the inside of the housing; and a reflecting plate which, placed in the bottom of the housing, reflect asymmetrically the incident rays originated from the above LED light sources with a number of triangle-shaped projecting parts and act as an indirect lighting device as it lets each of the above mentioned asymmetrically reflected rays combine and go to an intended direction in the form of a plane light source. The surface of the reflecting plate is covered with high polished synthetic resin.

Abstract: The present invention relates to an energy concentration device of united reflection with multilevel solar cell array comprising: a housing and solar cell parts, which are multilevel arrayed inside or outside the housing in such a way that the part of collected sunlight is absorbed in each level and then the rest of unabsorbed sunlight is absorbed overall from multilevel of solar cells in the iterating process of reflecting sunlight on the surfaces of solar cell parts. By the present invention, if an energy concentration device of united reflection with multilevel solar cell array is attached to the solar concentration device and so on, it is possible to attach to both fixed type and movable type. In the process of reflecting and absorbing sunlight continuously to maximise sunlight availability, solar cell parts are arrayed multilevel to improve the collecting efficiency.
