Abstract
The invention provides an energy-saving power indicating circuit which comprises an LED (light-emitting diode), and the LED is connected to the live line and the zero line of the power respectively after being connected in series with a capacitor. The energy-saving power indicating circuit has the beneficial effects that, compared with the conventional resistor-type power indicating circuit, the power consumption thereof is reduced by 98%; although only about 0.50W is reduced in a single circuit, the energy-saving effect generated is considerable in view of extensive application background of the circuit.
Description
(1) technical field
What the present invention relates to is a kind of power indicating circuit.
(2) background technology
General power indicator all adopts the mode of resistance series connection light-emitting diode to carry out the power supply indication, and this method is simple and reliable, and power consumption is lower, and it is not obvious that the user in use feels.
But this method causes to have certain power consumption on the resistance owing to adopt resistance mode to reduce series circuit current.Electric current is 3mA in series circuit, when total voltage is 220VAC, can calculate to such an extent that the circuit total power consumption is 0.6W, and this power consumption is accumulated still very big, so need the method is improved.
(3) summary of the invention
The object of the present invention is to provide and a kind ofly can reduce circuit power consumption, satisfy the indicator circuit for energy-saving electric power of energy-saving and cost-reducing demand.
The object of the present invention is achieved like this: it comprises luminescent device, and described luminescent device is light-emitting diode or neon bulb, and luminescent device and capacitances in series are received on the live wire and zero line of power supply.
Described electric capacity is polarity free capacitor.
The invention provides a kind of new power supply indication technology, especially refer to a kind of resistance drop low current mode of passing through to change,, break through traditional resistance-type AC power indicating circuit design limitation whereby to reach the power supply purpose of indicating, reduce circuit power consumption, satisfy energy-saving and cost-reducing demand.
The present invention adopts idle devices such as electric capacity to connect with light-emitting diode, can satisfy reduction by the led current needs according to the complex impedance computing.Because electric capacity only produces idle, so the total active power of circuit is the power consumption of light-emitting diode, be (brightness decision of the different light-emitting diodes that this power consumption is caused by the difference appearance value of actual series capacitance) about 5mW, because electrical network is a perception, also can produce limited useful influence after the series capacitance again to the power factor of electrical network integral body.
The device (circuit) of non-pure electric capacity such as employing inductance also can be satisfied the demand, but because can there be conductor resistance in inductance, so power consumption can increase to some extent.
Beneficial effect of the present invention is that power consumption of the present invention has reduced about 98% than resistance-type power indicating circuit power consumption commonly used, though single circuit has only reduced about 0.50W, consider the extensive use background of this circuit, the energy-saving effect of its generation is very considerable.Be exemplified below: Chinese family add up to 3.5 hundred million in 2004, if each household adopts a power indicating circuit of the present invention, China 15.3 hundred million kWh that can economize on electricity every year then, be equivalent to 13.5% of in August, 2008 Three Gorges plant generator peak period energy output, the energy output that is equivalent to 610,000 tons of standard coals, reduce 1,380,000 tons of CO2 emissions, 3600 tons of sulfur dioxide, 7000 tons of nitrogen oxide, and can save 1,510,000 tons the spent water resources of mine coal; Consider that each household has an indicating circuit incessantly, industrial also commonly used, so this numerical value is conservative estimation.
(4) description of drawings
Fig. 1 and Fig. 2 are two kinds of typical circuit structural representations of the present invention.
(5) embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1, the composition of indicator circuit for energy-saving electric power comprises light-emitting diode, and light-emitting diode and capacitances in series are received on the live wire and zero line of power supply.
In conjunction with Fig. 2, the composition of indicator circuit for energy-saving electric power comprises neon bulb, and neon bulb and capacitances in series are received on the live wire and zero line of power supply.
The invention relates to a kind of innovation of power supply indication technology, its exemplary embodiment is as follows:
(1) selects high withstand voltage electric capacity and light-emitting diode for use;
(2) electric capacity and light emitting diode string are connected on the live wire and zero line of power supply.
Electric capacity should be selected polarity free capacitor for use, and its appearance value needs to calculate according to the brightness of required light-emitting diode, and withstand voltage needs the demand greater than the access power source voltage.
Claims (2)
1, a kind of indicator circuit for energy-saving electric power, it comprises luminescent device, it is characterized in that: described luminescent device is light-emitting diode or neon bulb, luminescent device and capacitances in series are received on the live wire and zero line of power supply.
2, indicator circuit for energy-saving electric power according to claim 1 is characterized in that: described electric capacity is polarity free capacitor.
