Abstract: A positioning system and a positioning method based on radio frequency identification techniques (RFID) are provided. The positioning system includes in-vehicle devices, RFID readers and a server. The in-vehicle devices each includes a positioning device, an image capturing device and an image recognition module. The positioning device obtains a positioning location. The image capturing device captures a driving image. The image recognition module identifies adjacent vehicles, adjacent license plate information, and road attributes, and calculates relative location information. Each of the RFID readers reads a vehicle tag of one of the vehicles passing by, so as to mark a reference vehicle and generate reference vehicle information. A positioning adjustment module of the server determines whether the target vehicle is a reference vehicle, has been the reference vehicle or is a non-reference vehicle, and adjusts the positioning location of the target vehicle in different ways, accordingly.

Abstract: A lamp holder structure includes a slide groove at a central portion thereof for insertion of pins of a fluorescent tube, two oblique guide plates at two sides of an outer end of the slide groove, and a bell mouth defined between the two guide plates. Through the guide plates to form the bell mouth, the pins of the fluorescent tube can be inserted into the slide groove easily and conveniently, enhancing the efficiency of mounting the fluorescent tube.

Abstract: A socket bulb includes a shell inside which a depression device, a clamp device, and conductive plates are arranged. The shell has a lower opening through which the base of a bulb can be put into the shell in a linear movement. Depression operation of the depression device by the base of the bulb moves the clamp device to move between a raised position and a lowered position. When the clamp device is moved from the raised position to the lowered position, the bulb is securely retained inside the shell in electrical engagement with the conductive plates through which power is supplied to the bulb. When the clamp device is moved from the lowered position to the raised position, the bulb is released and can be withdrawn easily. As such, an efficient and safe structure for mounting and dismounting a bulb in a socket is provided.

Abstract: A fluorescent-lamp tube seat is disclosed.

Abstract: A lamp socket for holding lamp tube is disclosed. The socket comprises a base seat with a front face having a cavity slot with an open end and the lateral walls of the cavity slot being an arch-shaped portion and a top end disposed with a sliding slot in communication therewith. Two conductive pegs are provided to the bottom edge of the arch-shaped portion and two wire securing conductive plates are connected to the conductive pegs. A panel is sued to cover the front face of the base seat and the body of the panel is provided with a guiding slot to parallel guide the sliding of the pins of the lamp tube. A lamp pin engaging device including an urging element, and having two lateral sides is provided with conductive copper plates. The center region of the engaging device is disposed with an interlining shaft which can be extended up and down. The urging motion of the interlinkig shaft will shift the urging plate to be at high or low position.

Abstract: The present invention relates to an improved structure of a fluorescent light-tube seat comprising a base seat, a panel, an axle, an engaging peg, a spring, a hole covering an “Π”-shaped member, two conducting copper plates, wherein two fluorescent light-tube seats are used as one module to facilitate the installation of the fluorescent light-tube by vertically repeating pushing dismantling action of the fluorescent light-tube.

Abstract: The present invention relates to a copper head socket for light bulb comprising (a) a base seat having an open end and another end having a cylindrical shape center shaft hole; (b) a connection seat which is a hollow cylinder; (c) a threaded base seat including two corresponding member hingedly mounted together at one end to grip the copper cap of the light bulb and the other end of the threaded seat being a center aperture; (d) a press-stopping; and (e) a hole cap. In accordance with the present invention a copper capped electrical light bulb can repeatedly urge the socket so that the loading and/or unloading of a light bulb can be achieved easily and conveniently.
