Summary
This paper develops an improved method for calculating LED illumination in agricultural premises that accounts for lamp geometry and a correction factor (0.8) missing from traditional point methods, validated against ANSYS/CFX and DIALux evo software. Implementing energy-saving LED lighting with simulated dawn/dusk cycles and 15–16 hour photoperiods can increase agricultural production by 8–15% while reducing electrical energy consumption by 85%.
Key Findings
- Simulating sunrise/sunset and extending daylight hours to 15–16 hours can raise livestock/poultry production levels by 8–15%.
- Switching to the designed LED lamp system reduced electrical energy consumption by 85% compared to conventional lighting.
- Average illumination level achieved was 123.1 lux using the new LED lamp design.
- A correction factor of 0.8 for changing illumination under LED lamps was identified as necessary to reduce error in theoretical calculations.
- Statistical validation showed correlation coefficients and Student/Fisher criteria within acceptable tabular values, confirming the model's reliability.
