LED teeb siv hluav taws xob ntau npaum li cas?
LED teeb muaj zog heev -ntau, sivtsis tshua muaj hluav taws xobdua li cov khoom siv hluav taws xob los yog CFL qhov muag teev. Nov yog cov ncauj lus kom ntxaws txog lawv cov kev siv zog:
1. Kev siv hluav taws xob ntawm LED teeb (Watts vs. Lumens)
Watts (W)= Lub zog siv (koj them li cas).
Lumens (lm)= Brightness tsim.
| Noob Hom | Qhov nruab nrab Wattage (W) | Lumens (Brightness) |
|---|---|---|
| LED | 4–15W | 450-1600 dr hab |
| Incandescent | 40–100W | Tib qhov ci ci |
| CFL | 9–25W | Tib qhov ci ci |
Piv txwv:
A 10W LED teebtsim ~ 800 lumens (sib npaug rau a60W incandescent teeb).
Khiav nws rau5 teev / hnubtus nqi txog$0.15–$0.30 ib hlis(nyob ntawm tus nqi hluav taws xob).
2. xam cov nqi hluav taws xob LED
Formula:
Tus nqi =Watts × Teev Siv 1000 × Tus Nqi Hluav Taws Xob (ib kWh) Tus Nqi=1000Watts × Teev Siv × Tus Nqi Hluav Taws Xob (ib kWh)
Piv txwv xam:
1 x 10W LED teeb, siv5 teev / hnub, at$0.12 per kWh:
10 × 5 × 301000 × 0.12=$ 0.18 ib hlis 100010W × 5 × 30 × 0.12=$ 0.18 ib hlis
10 x 10W LEDs(tag nrho tsev)=~$1.80 / hli(vs.$10+rau incandescents).
3. Cov yam ntxwv cuam tshuam rau kev siv hluav taws xob LED
Dimmable LEDssiv tsawg zog thaum dim.
Xim kub(sov vs. txias dawb) tsis cuam tshuam wattage.
Ntse LEDs(xws li Philips Hue) siv me ntsis ntxiv hauv hom standby (~0.5W).
4. LED vs. Lwm qhov muag teev: Cov nqi sib piv txhua xyoo
| Noob Hom | Wattage | Tus Nqi Txhua Xyoo (5h/hnub, $0.12/kWh) |
|---|---|---|
| LED | 10W | ~$2.20 |
| CFL | 14W | ~$3.07 |
| Incandescent | 60W | ~$13.14 |
Txuag:Hloov ntawm incandescent mus rau LED txiav cov nqi teeb pom kev zoo los ntawm~80%.
5. Puas LEDs siv hluav taws xob thaum tua?
Ntse / Wireless LEDstuaj yeem siv0.2–0.5Wnyob rau hauv standby (tus nqi negligible).
Standard LEDs(tsis muaj ntse nta) siv0W thaum tawm.
Teb kawg:
Ib leeg5W-15W LED qhov muag teevtus nqi$0.10–$0.50/ hlinrog rau kev siv.
Tag nrho - LED teeb hauv tsev(20 lub teeb) ≈$2–$5/ hli(vs. $20+ rau incandescents).
Savings Tip:NrhiavENERGY STAR- ntsuas LEDsrau siab tshaj plaws efficiency.
