The present invention relates to a single-surface light emitting lamp for bidirectional lighting capable of reducing the number of single-surface light emitting components while maximizing the effect by dividing linear light from a single-surface light emitting component into the left and the right by 90°, and a bifacial advertisement structure (protruding signboard, bifacial signpost, or bifacial billboard). To achieve the objective in the present invention, a reflector including two reflection surfaces of which the ends meet together to divide the light radiated onto a frontal surface, towards which a single-surface light emitting component operated by stable power rectified by an SMPS from a commercial AC power or a single-surface light emitting module composed of a plurality of single-surface light emitting components radiates light, to the left and the right by 90° is fixed using a support to compose a single-surface light emitting (LED, OLED) lamp for a bifacial advertisement structure. Within the bifacial advertisement structure having advertisement surfaces on which an advertisement is printed on both sides, two or more light installation frames are included in the vertical or projection direction. Onto the frames, the single-surface light emitting lamp is installed, so the lamp emits light onto the advertisement surfaces at night to brighten the advertisement. Different from the existing examples in which two light emitting components are used to brighten two advertisement surfaces in opposite directions; the present invention divides light from a single light emitting component into the left and the right by 90° and radiates light in two opposite directions, thereby reducing the number of single-surface light emitting components necessary to light the advertisement structure while maximizing the effect. |
