Abstract: A series-type LED lamp strip module includes a first LED lamp strip module and a second LED lamp strip module. The first LED lamp strip module and the second LED lamp strip module both include a power switch controller, at lease one LED lamp strip, a signal output adaptor, a signal input adaptor, a power plug, and a power socket. The power plug of the second LED lamp strip module is inserted into the power socket of the first LED lamp strip module, and the signal output adaptor of the first LED lamp strip module is electrically connected to the signal input adaptor of the second LED lamp strip module so as to connect the first LED lamp strip module and the second LED lamp strip module. In addition, a microcontroller unit outputs a control signal to lighten light emitting diodes in different types to produce multiple brightness variations.

Abstract: An LED control system using a modulated signal includes a computer, a data storage unit, an AC power, a power conversion circuit, a control circuit, and an LED lamp string. The AC power is converted into a DC power by the power conversion circuit to supply a DC voltage to the control circuit and the LED lamp string. A computer control data is sent to the control circuit through the data storage unit by a user using the computer. The computer control data is modulated to a modulated signal by the control circuit. The modulated signal is sent to the LED lamp string with the same transmission line sending the DC voltage. The light of the LED lamp string is changed according to the modulated signal. The cost is reduced because the DC voltage and the modulated signal are sent in the same transmission line.

Abstract: A parallel type single-wire addressable light device includes a microprocessor, at least one lighting module and at least one signal amplifier. The microprocessor includes an address transmission line and a data transmission line. The plurality of lighting modules is composed of a control driver and at least one lamp set, and the control driver is connected in parallel to the microprocessor through the address transmission line and the data transmission line. The signal amplifier is electrically connected between the microprocessor and the control driver. The address transmission line of the microprocessor transmits an address define signal to set the address of each lighting module, and then the data transmission line outputs data to control any one or any two or more lighting modules for controlling a change of light.

Abstract: A circuit driving electric luminescent panel in which the high potential contact of electric luminescent panel is connected to two parallel connected transistors of which the emitter of the first transistor is connected to a current--resisting coil and the positive pole of a diode in order to raise the voltage at the contact of the electric luminescent panel. The first transistor provides, within the time when the signal at its base is low, a negative voltage to increase the peak value-to-peak value voltage across the electric luminescent panel and its luminosity as well. Furthermore, another kind of design concept is presented with which the timing impulse of controlling signals while operation can be governed with its duty to control current consumption.
