Patent ID: 6874904

Claim:
An electroluminescent device comprising: a base panel including an upper surface and a bottom surface, at least one electroluminescent laminate attached onto said bottom surface of said base panel, a pattern attached onto said upper surface of said base panel, and including a first space, a second space, and a third space provided thereon, said third space being provided around said second space of said pattern to have said second space arranged within said third space, and said second space being provided around said first space of said pattern to have said first space arranged within said second space, a mercury powder material applied onto said first space of said pattern, for generating less brightness, a crystal powder material applied onto said second space of said pattern, and including a brightness greater than that of said mercury powder material, a quartz powder material applied onto said third space of said pattern, and including a brightness greater than that of said crystal powder material, a film applied onto said upper surface of said base panel, to shield said pattern, a film applied onto said bottom surface of said base panel, to shield said at least one electroluminescent laminate, means for energizing said at least one electroluminescent laminate to generate light through said pattern, and to generate light of different brightness through said mercury powder material and said crystal powder material and said quartz powder material, a quartz powdermaterial, said energizing means including a circuit board electrically coupled to said at least one electroluminescent laminate, and at least one battery attached to said circuit board to energize said at least one electroluminescent laminate, said circuit board including at least one processor and an inverter disposed thereon and coupled with each other, said inverter being coupled to said at least one electroluminescent laminate, and a switch device attached to said circuit board, in order to control said at least one electroluminescent laminate.
