Devices utilizing light-emitting diodes (LEDs), configured in elongated, flexible arrays, and emitting light across the photosynthetically active radiation (PAR) range, represent a horticultural lighting solution. These systems are designed to provide plants with the necessary electromagnetic radiation for photosynthesis, mimicking sunlight. The spectral output encompasses wavelengths from approximately 400 nanometers to 700 nanometers, covering blue, green, and red regions, with varying intensities depending on the specific design and purpose.
The application of these lighting systems in controlled-environment agriculture contributes to enhanced crop yields, accelerated growth rates, and improved plant health. Historically, traditional lighting sources, such as high-pressure sodium (HPS) and metal halide lamps, were prevalent. However, LED technology offers superior energy efficiency, reduced heat generation, and the ability to customize spectral output to match the specific requirements of different plant species and growth stages, which benefits sustainability and reduces operational costs.
