LED Dönüşüm Ne Kadar Sürede Geri Öder?

Annual savings from LED conversion pieces × (Pmevcurrent − PLED)/1000 × hours × 365 × tariff It is calculated using [method name], and the payback period is the total investment divided by the annual savings. In most facilities, the payback period is less than a few years, provided the lighting level (luxury) is maintained.

Annual savings = units × (Pₘ−P_LED) / 1000 × hours × 365 × tariff
Example calculation: 120 fixtures, 72 W → 32 W, 10 hours a day, 3.5 TL/kWh, 60,000 TL investment → annual savings of ≈ 17,520 kWh and ≈ 61,320 TL; investment pays for itself in ≈ 12 months.

Notes: Annual savings = units × (Pcurrent − PLED) / 1000 × hours × 365 × tariff. The calculation assumes 365 days of operation per year; actual savings will vary depending on the operating schedule, maintenance costs, and luminaire lifespan. The lighting level (lux) must be maintained — see diagram. Lighting Suitability.

Frequently Asked Questions

How much can be saved by switching to LED?
The savings depend on the number of lighting fixtures, power difference, operating hours, and tariff; it gives the vehicle's annual TL savings and payback period.
What is the payback period for LED conversion?
It is calculated by dividing the total investment by the annual savings; in heavily used facilities, this is generally 1–3 years.
Will the lighting level be reduced when calculating energy savings?
With proper design, the illumination level (lux) is preserved; after conversion, compliance with EN 12464-1 references should be checked.
