  • Publication number: 20050094400
    Abstract: A chain controlled lamp stand with multi-stage light modulation includes a control device to modulate brightness of a lamp. The control device consists of a chain-controlled switch and a light modulation circuit board controlled by the chain-controlled switch to modulate the brightness of the lamp. The chain-controlled switch in the lamp stand is combined with a rotatable disc, which can be actuated to rotate at its original location by a pull chain. The rotatable disc is assembled thereon with a conducting metal contact strip, and the light modulation circuit board is provided with multi-stage connecting strips, which are able to change, and control voltage waveform. Thus, the metal contact strip is actuated to contact respectively with the multi-stage connecting strips to carry out multi-stage light modulation of the lamp stand.

  • Publication number: 20040247297
    Abstract: The present invention provides a circuit and method for playing back digital data in a displayer, which is used to reduce the power consumption of a computer host, and by configuring a digital playback circuit in the displayer to make the video data itself being directly played back with the displayer. Thus, even the CPU of the computer host is not energized, the user himself still can operate the display to achieve the playing back of the digital video data, so that the user still can obtain different playing back interfaces to reduce the power consumption of computer host, and minimize the possible loss of computer working time.

  • Patent number: 6768072
    Abstract: A multi-directional switch grip includes an insulating body, a lamp socket and an insulating disc positioned between the insulating body and the lamp socket. A pair of terminals, an intermediate contact member and a rotating member with a ratchet respectively on two sides is fixed in the insulating body. A conductive member fits around a large ratchet and has half numbers of contact pieces as that of the large ratchet. One of the terminals and the intermediate contact member contact the teeth of the large ratchet in a turned off condition, or contact the contact pieces in a turned-on condition. A switch grip is provided to be pulled or bent in any direction to move a hooking member, which moves and rotates the large ratchet for a set angle to turn on the switch and the switch is turned off by repeating the same action.

  • Publication number: 20040014364
    Abstract: A lamp socket having a double-deck center contact strip includes a socket body having an inner hollow provided with a metal threaded sleeve for receiving a lamp. The socket body is provided inside with a curve-shaped center contact strip having one side fixed on the socket body, and the other side turning upward and located in the center of the threaded sleeve but separating from the threaded sleeve. The double-deck center contact strip is composed of a copper and a steel contact strip, the copper contact strip located on top for contacting with the contact under a lamp and conducting elasticity, while the steel contact strip positioned under the copper contact strip for reinforcing the elasticity of the center contact strip, thus maintaining good contact between the lamp socket and the lamp for conducting electricity well, prolonging service life and ensuring safety.

  • Patent number: 6495970
    Abstract: A lamp stand with multi-stage light modulation includes plural resistors annularly arranged to form a circular space. The resistors have terminals soldered on the outer walls of U-shaped contact blades, with an empty position terminal provided in the circular space. A light-modulating controller extends in the lamp stand, having a rotor formed with plural slopes on an outer wall for rotor copper strips to rest thereon. A trigger diode is connected to the gate of a triac AC switch and a capacitor is connected to the trigger diode and the paralleled terminals of the resistors and to the main terminals of the triac AC switch. The light-modulating controller is rotated to let the rotor copper strips contact the contact strips of the resistors to turn on power and charge the capacitor. Different resistance values change the breakdown speed of the DIAC and control the gate of the TRIAC to change the voltage effective value of the lamp, thus reaching a goal of light modulating.

  • Patent number: 6287152
    Abstract: A rotatable socket for a halogen-lamp. The socket includes a porcelain base having two insert grooves at its bottom and an H-shaped upright post standing on the bottom. A plus and minus contact members respectively positioned in two opposite recessed sides of the H-shaped upright post. The top end of the plus contact member rests on a protruding lug on the top center of the H-shaped upright post. The top end of the minus contact member rests on the top of the right side wing of the H-shaped post. A mica plate is fitted on the H-shaped post and a metal threaded sleeve surrounds the H-shaped post and is fixed with it by rivets, permitting the top end of the plus contact member to protrude out in order to function as a plus terminal and an upper rim of the threaded sleeve presses the top section of the minus contact member to function as a minus terminal.

  • Patent number: 6255613
    Abstract: A revised structure of a distribution box of an on-line switch essentially comprised of a distribution box base, wherein four separated wire slots are formed and the left, right and base of the slot are in the shapes triangular of pyramid convexes, a box cover, wherein wire-pressing convexes which correspond to the convexes of the distribution box base are made, and a control element, which is inserted in the space created after the distribution box base and the box cover; after the electric wire being inserted in the wire slots and the distribution base and the box cover being assembled, the convexes can compress the electric wires in four directions and in turn grip the electric wires firmly, preventing the electric wires the risks form loosening, or even falling off, under improper pulling.

  • Patent number: 6186822
    Abstract: A lamp socket with a pull string switch includes a socket body, a screw base, and a pull string switch combined in the socket body. The improved feature is two power lead protectors formed on an upper end surface of the socket body for separating two power leads so that the power lead protectors may hamper accidental force of pulline the power leads from directly transmitted to connect points of the power leads. Thus the connect points may not disconnected from the terminals or become badly connected with the terminals, keeping good quality of the power leads in transmitting electricity and safety of using electricity.

  • Patent number: 6171135
    Abstract: A lamp base includes a base body, a lamp socket fixed under the base body, a housing protecting the base body and the lamp socket, and a cap closing up the housing. To terminals are provided in the base body to connect to two power wires passing through an upper wire hole of the cap. The cap has a short tube portion extending down from the wire hole to press down the power wires on an upper surface of the base body to secure the power wires tightly so as not to loosen off the two terminals if exterior force should pull the power wires by accident.
