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 method for controlling a constant-pressure fluid enables an inverter with a build-in controller to control rotation speed of a pump to achieve constant-pressure control thereof. In the control method, a pressure feedback value of output flow of the pump is measured and is compared with a pressure reference value to produce an error pressure value. Afterward, an operation condition of the pump, such as an abnormal handling condition, a deceleration standby handling condition, or an acceleration condition, is determined according to the pressure error value to shut down or re-start up the pump after a delay time. Hence, the control method can avoid frequently starting up or shutting down the inverter. Therefore, the power consumption and the operation cost are reduced. The use life of the pump prolongs and constant-pressure control for the pump can be implemented.
