The present invention provides a circuit for driving a vehicle lamp, comprising a dummy load. Multiple unidirectional conduction electronic components are coupled to the dummy, operable for conducting a current path to enable a current to flow through the dummy load. Each of multiple LED strings is coupled to each of the multiple unidirectional conduction electronic components, respectively.

Circuit for vehicle lamps

A liquid-filled display device includes a hollow member mounted on a transparent top end wall of a hollow base and confining a water-tight inner space filled with a liquid body, and a display unit mounted on the top end wall and having a top wall and two transparent sidewalls connected to the hollow member. The sidewalls and the top wall cooperate with the hollow member and the top end wall to confine a display space. At least one of the sidewalls is provided with an advertisement. An air pump unit is mounted in the base, and is operable so as to supply fine air bubbles into the liquid body through a diffuser set mounted within the inner space. A lamp unit mounted in the base beneath the hollow member is operable so as to radiate colored light that penetrates through the top end wall into the inner space.

Liquid-filled display device

An advertisement stand includes a transparent hollow member mounted on a hollow base, and confining a water-tight inner space filled with a liquid body. The hollow member has a surrounding wall adapted to be printed with an advertisement thereon. An air pump is mounted in the base and is operable so as to supply fine air bubbles into the liquid body via a diffuser set which is mounted on a bottom end of the hollow member. A lamp set is mounted on the base and is disposed beneath the hollow member. The lamp set is operable so as to radiate light that extends through the bottom end of the hollow member. The lamp set includes a first lamp unit disposed adjacent to the surrounding wall, and a second lamp unit surrounded by the first lamp unit.

In a method for producing a semiconductor device using a logic simulation approach, a circuit model for a user-specified design of a multi-peak resonant tunneling diode-based electronic circuit is provided and includes a plurality of circuit devices. One of the circuit devices is a multi-peak resonant tunneling diode which is modeled by a parasitic resistance in series with parallel combination of a voltage-controlled current source and an intrinsic capacitance. The voltage-controlled current source has an equivalent circuit model with a function stage for realizing current-voltage characteristic curve of the resonant tunneling diode. The function stage includes parallel combination of at least one first circuit branch, at least one second circuit branch and a third circuit branch. Each of the first and second circuit branches has a resistor, a diode and a voltage source. The third circuit branch has a resistor and a voltage source. The first and third circuit branches represent positive resistance sections, and the second and third circuit branches represent negative resistance sections of the current-voltage characteristic curve.
