Title: LED surface cover, and LED lighting system, display device

Abstract: An LED surface cover (1) consists of a resin molding and has a main reflector (2) which reflects light forward from a surface light source and a subsidiary reflector (3) having a reflection surface which reflects light emitted from an LED light source (4) to the main reflector (2). The main reflector (2) has an aperture portion (2a) were the LED light source can be disposed and has a curved surface for traveling light reflected from the subsidiary reflector (3) to a region forward from the surface light source. The subsidiary reflector (3) is disposed above the aperture portion (2a) formed on the main reflector (2). The reflection surface of the subsidiary reflector (3) has an inclination with respect to a surface of the aperture portion (2a). The present invention provides a lighting system capable of accomplishing surface emission by carrying out a simple method, even though the LED light source (4) having a strong directivity is used.
