Patent ID: 8608513

Claim:
A lamp, comprising a plurality of independent block bodies, each comprising at least one convex connector and at least one concave connector, wherein at least one block body has a luminous body, at least a part of the convex connector and the concave connector has an electrical connection component, the electrical connection component and the luminous body are connected electrically, when one block body and an adjacent block body are assembled together, the convex connector of one of two block bodies is plugged into the concave connector of the other of the two block bodies so as to combine the two block bodies tightly, as a result the electrical connection components of the two block bodies are connected physically and electrically, wherein the convex connector comprises the electrical connection component formed by an inner conduction column and an outer conduction ring, an insulation ring between the inner conduction column and the outer conduction ring, and a positive terminal and a negative terminal that are connected to the inner conduction column and the outer conduction ring, respectively, the inner conduction column extends out from the outer conduction ring; the concave connector comprises the electrical connection component formed by an outer-layer conduction ring and an inner-layer conduction ring, an insulation ring between the outer-layer conduction ring and the inner-layer conduction ring, and a positive terminal and a negative terminal that are connected to the inner-layer conduction ring and the outer-layer conduction ring, respectively, the outer-layer conduction ring extends out from the inner-layer conduction ring.
