Conas an teocht dath ceart a roghnú le haghaidh lampaí stiúir?
Anois tá trealamh soilsithe LED tí teocht dath éagsúla ar an margadh, mar shampla bán te, fíor bán, bán nádúrtha, bán fionnuar, buí te, solas na gréine, etc. Nuair a roghnaíonn custaiméirí lampaí, is minic a bhíonn sé deacair a thuiscint cad is ionann na téarmaí seo. . Cén cineál solais, cibé an bhfuil sé cad ba mhaith leat.
In the industry, the United States and many countries have put forward strict performance requirements for LED lighting applications. In 2007, the first industry policy was introduced: "Energy Star Program Solid State Lighting Requirements". The 2010 document follows: "Energy Star Program Integral LED Lighting Requirements." Each document contains requirements for correlated color temperature, color rendering index, lumen, and color maintenance for ENERGY STAR-approved LED lighting products, and has since been revised. The correlated color temperature requirements are summarized in Tables 1 and 2. There are only four color temperatures for home lighting, 2700K, 3000K, 3500K and 4000K, which means that this is an industry standard. And starting from 5000K is limited to commercial use.
Go deimhin, tá trí theocht dath den chuid is mó ag na lampaí a úsáidimid inár saol laethúil, bán te, bán nádúrtha agus bán dearfach. Tar éis na pictiúir thíos a léamh, creidim go bhfuil a fhios agat cheana féin conas a roghnú.
