Description

The control circuit of sound controlled LED lamp

Technical field

The utility model relates to a kind of control circuit of indoor illumination, exactly, relates to the control circuit of a kind of controlled LED lamp, belongs to the technical field of lighting apparatus or residential housing match appliance.

Background technology

On October in 2008 10, European Union member various countries have just started " program of forbidding incandescent lamp and other highly energy-consuming lighting apparatus stage by stage ", draft from 2010 and forbid selling the highly energy-consuming home lighting equipment that comprises incandescent lamp in European Union.Forbid selling 100 watts incandescent lamp bulb before this, then banned use of the bulb of 60 watts and 40 watts, soon, 25 watts also will be eliminated from vehement lamp.European Union's ban is intended to save 1% power consumption at least in European Union's member various countries scope.In June, 2007, the light fixture manufacturer of European Union has just determined the time with 8 years, just by 2015, stops to sell incandescent lamp fully on European Union market.

In today that environmental protection and energy problem highlight day by day, as if allow the incandescent lamp of high energy consumption, low effect step down from the stage of history has become whole world common recognition, allows the incandescent lamp of illuminating product replacement more efficiently also become the certainty of social development.This is that all the other 95% electric energy all are converted into heat exhaustion and have fallen, so the trend that incandescent lamp bulb is eliminated is inevitable because the luminous efficiency of incandescent lamp bulb only has 5%.Except each member state of European Union, incandescent lamp is also progressively being eliminated in global other countries and area.Such as, New Zealand drafts in recent years and eliminates incandescent lamp, and Japan also will forbid incandescent lamp comprehensively, and China is also studying and is progressively eliminating incandescent lamp timetable and relevant supplementary measures.

Now, numerous light fixture produces in the crystalline substance on the illumination market, the LED(light-emitting diode of efficient energy-saving) the test and appraisal mark of light fixture is the highest, its environmental protection and energy saving, long service life, and also the luminous efficiency when just turning on light is big.Compare with original old-fashioned incandescent lamp bulb, can save nearly 90% electric power.At present, though on price, may be also higher a little, but the LED lamp life-span prolongs 25 times than incandescent lamp.In Germany, as a kind of selection of excellent lighting, LED lamp and electricity-saving lamp are the highest two kinds of cost performance.

At present, after successfully occupying a tiny space in mobile phone, automobile and television industries, the LED sectional plan marches illumination market.Compare with other light fixtures, the luminous efficiency height of LED lamp, along with the lifting of production lot, its price is also in downward modulation.Annual average downward modulation about 30% now.Investigation and analysis according to Mai Kenxi. price is 20 Euros LED lamp now, time the year two thousand twenty, just can buy less than 3 Euros.

Since downward price adjustment, scholarly forecast, and this high-tech bulb will large-scale production in next year.Japan is because live through nuclear catastrophe, and saving the energy has become "sport for all", and the history of LED is used very general.

In addition, though a feast for the eyes compact fluorescent lamp (being commonly called as electricity-saving lamp) of choice maximum in the market, and, the electric energy that electricity-saving lamp consumes is only more than LED lamp, but the defective of its existence is: after opening switch, the phenomenon that lighting time postpones often takes place; In addition, its brightness is also less than incandescent lamp or LED lamp.Moreover the greatest weakness of electricity-saving lamp is the mercury that contains the serious environment pollution performance.Expert advice, if smashed the electricity-saving lamp in a room, must be to major general's ventilation of room 30 minutes, and withdraw from a room.Then, fragment is collected with wet cloth or adhesive tape, and it is handled as specific refuse.The expert also advises, if spread carpet in the room, behind dust catcher cleaning fragment, also carpet should be thrown away into refuse bag.Therefore, eliminate power saving fluorescent lamp, not only reduce the use of electric energy, also reduced environmental pollution simultaneously.

But, at the investigation in the acoustic control illuminating lamp market of present dwelling house or office building with analyze and find: the acoustic control series switch of existing illuminating lamp, can only be applicable to incandescent lamp, can not be used for electricity-saving lamp or LED lamp, its reason is: utilizing bidirectional triode thyristor to carry out in the frequent switching process of lighting circuit, present audio-switch control circuit makes that electricity-saving lamp is easy to damage; If change the LED lamp into, then have no progeny in the pass because of this audio-switch control circuit, circuit still can occur and turn-off not tight situation, its residual voltage makes that the LED lamp is shinny slightly and produces scintillation simultaneously; Not only can not play the illumination effect, also make human eye very uncomfortable, and shorten the useful life of LED lamp.So just make applying of LED lamp be very limited.

If all change the acoustic control series switch of present corridor lighting into the use novel product without exception, just can avoid above-mentioned defective although it is so, but, because the corridor in dwelling house, office building and the public building that comprises that has now built up has all been buried the audio-switch that illuminating lamp has been installed underground, this simple replacing certainly will will spend great amount of manpower, financial resources and material resources, also take a lot of work, time-consuming, effort, so be difficult to so far realize and promote.
