Optimization of LED lighting system for horticulture application – A simulation

Research output: Contribution to journalArticlepeer-review


The scope for application of Light Emitting Diodes (LEDs) as grow lights has enhanced significantly in the recent past. The place of LEDs as the most commonly used lighting fixtures in the horticulture industry looks imminent in the near future. LEDs have the capability to be provided desired light quantity and quality which aids the plant growth. Plants mainly absorb the red and blue spectrum for their growth and development. In this paper various Spectral Power Density (SPD) models were simulated and compared with practical SPDs. On comparison of different SPD model functions, the Asymmetric Gaussian function provided very good overlap. Database of several LEDs were created and LEDs were modelled. Linear Programming (LP) code was developed for spectrum matching and optimizing the number of LEDs. Also the Correlated Color Temperature (CCT) and Photosynthetic Photon Flux Density (PPFD) of the simulated spectrum were compared with the reference spectrum. The SPD models and LP were simulated using MATLAB software.
