An bhfuil na soilse faoi stiúir éifeachtach ó thaobh fuinnimh de? An sábhálann sé cumhacht i ndáiríre?
Before this, the lighting industry has never been so beautiful. Needless to say in the industry, under the general environment and trend of energy saving, emission reduction and green environmental protection, it is an industry consensus and the general trend that LED will become the mainstream light source of future lighting. Even in the street talk of the consumer market, when it comes to lighting, although most of them know little about it, no one knows about LED. This half is naturally due to the government's strong support and promotion, and the other half is due to the advantages and charm of LED technology itself.
I súile an phobail i gcoitinne, mar chineál nua teicneolaíochta soilsithe, tá stiúir comhionann go bunúsach le coigilt fuinnimh, agus is cosúil gurb é an praghas an t-aon chonstaic faoi láthair. Fiú sa tSín, níl an praghas ina fhadhb a thuilleadh (an chúis a bhfuil a fhios ag gach duine). Mar sin féin, an bhfuil lampaí stiúir i ndáiríre éifeachtach ó thaobh fuinnimh? Conas a mheas an bhfuil lampa stiúir éifeachtach ó thaobh fuinnimh?
1. Éifeachtúlacht lonrúil na foinse solais
Is dé-óid astaithe solais é LED (Dé-óid astaithe Solais), comhpháirt leathsheoltóra soladach stáit atá in ann fuinneamh leictreach a thiontú go solas infheicthe, díreach cosúil leis na lampaí gealbhruthacha agus halaigine traidisiúnta taobh thiar de phrionsabal an luminescence radaíochta teirmeach. , lampaí fluaraiseacha, lampaí mearcair, lampaí sóidiam agus lampaí óir Úsáideann lampaí halaigine an prionsabal céanna um urscaoileadh gáis, léiríonn an LED féin teicneolaíocht, prionsabal astaithe solais freisin.
Éifeachtúlacht lonrúil foinse solais (dá ngairtear éifeachtúlacht lonrúil go minic): cumas comhlacht lonrúil fuinneamh leictreach a thiontú go solas infheicthe, arna thomhas ag an gcóimheas idir flosc lonrúil agus cumhacht, i lm/w.
Mar chineál nua foinse soilsithe, tá teicneolaíocht stiúir níos airde ná teicneolaíocht foinse solais traidisiúnta. Mar sin féin, tá raon leathan éifeachtaí solais ag teicneolaíocht LED féin, agus níl sé cruinn a rá go bhfuil foinsí solais LED níos tíosaí ar fhuinneamh ná foinsí solais eile. Ní eolaíoch. Nuair a fhaigheann muid chomh maith, ní mór dúinn a fheiceáil conas a bhíonn an páirtí eile na Fraince, na Síne agus na Seapáine, agus tá an rud céanna fíor maidir le táirgí LED.
Déanta na fírinne, chun a mheas an bhfuil lampa coigilte fuinnimh, tá sé i bhfad níos mó ná an teicneolaíocht agus an fhoinse solais a úsáidtear.
2. Éifeachtúlacht fuinnimh leictreach
In addition to incandescent lamps and line voltage halogen lamps, other light sources need to be equipped with lighting appliances. Lighting appliances also have the problem of power utilization, that is, the ratio of the electrical energy used by the electrical appliances to drive the light source to emit light. Without considering the harmonics, the power factor λ is usually represented by cosφ. It doesn't matter if you don't understand these things. In short, the efficiency of lighting appliances usually needs to look at the power factor index.
Cuirfidh an chuid is mó de na monaróirí branda paraiméadair éifeachtúlachta córais fearais leictreacha ar fáil freisin ar shamplaí táirge nó ar leathanaigh aonair, mar a thaispeántar san fhigiúr thíos, is féidir lenár dearthóirí iarraidh ar mhonaróirí paraiméadair ábhartha a sholáthar.
3. Éifeachtúlacht soilsithe
Is furasta éifeachtacht na lampaí a thuiscint. I dtéarmaí simplí, is é an cóimheas idir an solas ag teacht amach as an lampa leis an solas a astaítear ag gach foinse solais sa lampa faoi choinníollacha caighdeánacha, de ghnáth in iúl ag LOR.
LOR=flosc lonrúil a astaíonn an luminaire / flux lonrúil gach foinse solais sa luminaire
Mar shampla, le haghaidh gnáth-phainéal lampa 318W, is é 3600lm flosc lonrúil iomlán na foinse solais. Más é flosc lonrúil tomhaiste an lampa ná 1800lm, deirimid go bhfuil éifeachtacht an lampa 50 faoin gcéad.
4. Éifeachtúlacht soilsithe
Leaving aside the light distribution and light utilization rate of lamps, and whether designers use lamps reasonably in the space (if the lighting design process is divided into three parts: light selection, light distribution and light use, our discussion today is limited to "selection". Light" part), to evaluate whether a lamp is energy-saving, it is necessary to combine the above three aspects to obtain the lamp efficiency:
Éifeachtúlacht luminaire=flosc lonrúil a astaíonn an luminaire/(cumhacht foinse solais móide caillteanas leictreach)=flosc lonrúil a astaíonn an fhoinse solaisLOR/(cumhacht foinse solais móide caillteanas leictreach)
5. An bhfuil lampaí stiúir éifeachtach ó thaobh fuinnimh?
Tar éis soiléiriú a dhéanamh ar na critéir chun a mheas an bhfuil lampa coigilte fuinnimh nó nach bhfuil, is féidir linn na buntáistí agus na míbhuntáistí a bhaineann leis an dá lampa seo a mheas.
Agus é ag glacadh le branda de lampaí grille 314W mar shampla, nuair a úsáideann sé trí lampa 14W/1200lm, atá feistithe le ballasta amháin-feadán 14W agus ballasta-feadán dúbailte 214W, cumhacht an chórais Is é 18 móide 32.5=50.5W. Is é LOR14 faoin gcéad éifeachtacht an lampa grille, ansin tá éifeachtacht an lampa 360070 faoin gcéad /50.5W=49.9lm/W.

When we are in the "light selection" part of the design, the main thing is to choose the right light source, the right electrical appliances, and the right lamps. The consideration of energy efficiency is an important aspect.
When considering energy saving in the design scheme, it is not only about which technology is used and what light source is used, that is to say, don't think that LED will inevitably save energy, but also depends on the actual parameters of light source, electrical appliances and lamps. Samples and measurements can best see the problem.
From this, we can also see that it is very unreasonable to spend a watt of LEDs that are very popular now, because the owners purchase lamps and lanterns to buy "light", not "power". Using yuan/watt to measure LED, it is very likely to buy LED products with low luminous efficiency and no energy saving. If you only consider the amount of light emitted by the lamps, perhaps a better indicator to measure the economy is yuan/1,000 lumens, that is, how much light you buy for how much. Whether these lights are used or not is another matter.
