Abstract
A lamp holder structure includes a base body, two electrode plates, a rotary shaft, a short-circuit part, and a cover. When multiple sets of lamp holder structures are used in serial connections, a shaft part of the rotary shaft is rotated by rotating a lamp-tube for the lamp holder structure. Conducting terminals of the lamp-tube are electrically contacted with the two electrode plates. Before rotating the lamp-tube, the short-circuit part is electrically contacted with the two electrode plates. After rotating the lamp-tube, the short-circuit part is electrically contacted with one of the two electrode plates. The electrical connection between the two electrode plates is achieved by the lamp-tube. When the lamp-tube is removed, the lamp-tube is rotated again, so that the short-circuit part is electrically contacted with the two electrode plates, and the two electrode plates are short-circuited. The power could be transmitted to the next lamp holder structure.
