The invention discloses an EL (electro luminescent) cold light cloud-pattern stone system, which comprises a semitransparent cloud-pattern stone (1) and a base plate (2); an EL cold light sheet is arranged between the semitransparent cloud-pattern stone (1) and the base plate (2); the semitransparent cloud-pattern stone (1) and the base plate (2) are combined to form a cavity in which the EL cold light sheet is arranged; and a waterproof sealing adhesive (5) is arranged around the cavity. The EL cold light cloud-pattern stone system of the invention used as a novel luminescent building material has a smallest thickness which can be controlled within 5 mm, soft glaze, bright color, and is non-dazzling, bendable and capable of entering into water, particularly suitable for being arranged at special parts and abnormal-shaped structures which cannot be realized by other light sources. The EL cold light cloud-pattern stone system has superior functions in the aspects of energy saving, carbon reduction, water resistance, environmental protection and the like. The EL cold light cloud-pattern stone system is a novel display light source and capable of providing more imaginary spaces and realization possibilities for increasing art elements and culture elements.
