Description

A kind of LED lighting energy saving control system

Technical field

The utility model relates to a kind of energy-saving control system, particularly relates to a kind of LED lighting energy saving control system.

Background technology

Show that according to BP energy report and EIA related data global power consumption was up to 15400000 m. gigawatt (GW)s in 2004.1/3 of the global energy consumption that accounts for, motor, illumination and power supply are then arranged into front three to the demand of electric energy, and three total ratios weigh 61%.When quality of life all generally improves, people to green, environmental protection, energy-conservationly also have higher requirement.The advantage of LED lamp is that energy-saving and environmental protection, life-span are long; And the LED lamp has the characteristic of general-purpose diode, can under on off state at a high speed, work, such as: 10 cubicles are arranged in a house; Each cubicle is with the LED lamp of 1 3W, 10 rooms ask light simultaneously will 30W power consumption.If sequenced the lighting of LED lamp high speed that lets these 10 rooms, it is bright having only 1 lamp at one time, because speed is very fast, will see that the LED lamp in all 10 rooms has all been lighted.Will save the electric energy of 50%-80% like this.And in the prior art, the energy-saving control system that Shang Weiyou is such to the design of LED illuminating lamp.

The utility model content

The technical problem that the utility model will solve provides a kind of LED lighting energy saving control system, can be effectively drops to the energy consumption of LED lamp minimum.

For solving the problems of the technologies described above; The utility model provides a kind of LED lighting energy saving control system; Comprise field effect transistor switch circuit, counter, light-operated circuit, oscillating circuit and be respectively the power module of field effect transistor switch circuit, counter, light-operated circuit, oscillating circuit power supply; The output of said light-operated circuit is connected with first input end, second input of said counter respectively with the output of said oscillating circuit, and the output of said counter is connected with the input of said field effect transistor switch circuit.

Further technical scheme, said counter is a decade counter, its 10 outputs are exported the work of high level control CMOS power field effect pipe in order.

Technical scheme further, said oscillating circuit is made up of first inverter, second inverter, first resistance and first electric capacity, and the waveform of generation is exported to counter behind the 3rd inverter.

The utlity model has following useful technique effect: design very rationally; Control through electronic circuit under the prerequisite of LED Lantern Festival ability further reduces its power consumption; Can under the common LED illumination application, save the electric energy of 50%-80%, the utility model can be applied in the centralized control field of single lamp holder or many lamp holders of many led chips.

Embodiment

Be elaborated below in conjunction with the preferred implementation of accompanying drawing to the utility model.

Embodiment:

As depicted in figs. 1 and 2; A kind of LED lighting energy saving control system; Comprise field effect transistor switch circuit, counter, light-operated circuit, oscillating circuit and be respectively the power module of field effect transistor switch circuit, counter, light-operated circuit, oscillating circuit power supply; The output of said light-operated circuit is connected with first input end, second input of said counter respectively with the output of said oscillating circuit, and the output of said counter is connected with the input of said field effect transistor switch circuit.Said counter is a decade counter, and its 10 outputs are exported the work of high level control CMOS power field effect pipe in order.Said oscillating circuit is made up of the first inverter U1A, the second inverter U1B, first resistance R 1 and first capacitor C 1, and the waveform of generation is exported to counter behind the 3rd inverter U1C.

In the present embodiment, this part effect of light-operated circuit is very simple, and the LED lamp is lighted when preventing daytime exactly.Resistance R 01 and the 3rd resistance R 3 form bleeder circuits by day the time or near the lamp light yellow is arranged, the resistance of resistance R 01 can be very little, the input of such the 4th inverter U1D is just drawn high, output just becomes electronegative potential.The current potential of output is directly controlled triode Q11 and Q12, because electronegative potential triode Q11 and Q12 end, so can't deliver to the input of counter like this owing to the output signal by oscillating circuit of triode Q12, counter quits work.In the time of night the resistance of resistance R 01 can be very the input of big such the 4th inverter U1D dragged down by the 3rd resistance R 3; Output just becomes the triode Q11 and the Q12 conducting simultaneously of high potential; The conducting of triode Q11 is that the conducting that makes the input point of the 4th inverter U1D be locked in electronegative potential (preventing the operate as normal of the variable effect LED lamp of light) triode Q12 is firmly delivered to counter to the signal of oscillating circuit; Let counter begin counting work, will light the LED lamp in turn at the output pin of counter.

Have one the tunnel to be not receive light control in 10 paths of LEDs of present embodiment circuit, in wiring, can be used according to actual conditions.

Counter portion is exactly to be made up of a slice decade counter, and its 10 outputs are exported the work of high level control CMOS power field effect pipe in order.The conducting resistance of this FET will very little very little (its size can influence the efficient of entire circuit).

It is energy-conservation to utilize light and eye storage characteristic to realize, in the energy so nervous period, the inventor finds that a lot of places daytimes also can display a light in place that should not bright lamp.The utility model can will be controlled the LED lamp in the place that light is arranged and can't open, and can pin the LED lamp of turning on is not again automatically influenced by the light of itself in the place of dark.Switch opens (lamp does not work), lamp was bright automatically when returned night when utilizing this function to go out by day.

Need to prove at last; The above is merely the preferred embodiment of the utility model; Rather than, anyly be equal to replacement or corresponding improvement to what the utility model technical characterictic did to the qualification of the utility model technical scheme, still within the protection range of the utility model.
