The key feature is spectrum tunability.Fixtures contain multiple independently controlled monochromatic LED chips(e.g.,deep red,far-red,blue,white)mixable via software to create countless spectral combinations.Integrated light and temperature sensors enable closed-loop control.Efficient thermal management aims to ensure spectral stability and long LED life.Can integrate with environmental computers for协同control with temperature,humidity,and CO2.
Key metrics include Photosynthetic Photon Flux Density(PPFD),photon efficacy(μmol/J),and spectral power distribution.Mounting height and density are precisely calculated based on target PPFD and crop light saturation points.The control system supports 0-100%dimming and pre-set daily light integral curves.Typically hung from structures,adjustable to plant height.
Primarily for supplemental lighting in glasshouses and polytunnels,especially in high-latitude regions with insufficient winter sunlight.Also used in multi-layer vertical farms,plant factories,and research greenhouses.Precise lighting can shorten growth cycles,increase yield,control morphology(e.g.,prevent stretching),and influence nutritional content(e.g.,increase brix,anthocyanins).
