The invention relates to the technical field of
greenhouse artificial light systems, and discloses an LED
light source spectrum formula for tomato planting and an LED
light source module. The spectrum formula comprises UV light with
photon energy accounting for 1-3% of
total energy,
blue light with
photon energy accounting for 20-26% of
total energy,
green light with
photon energy accounting for 10-15% of
total energy,
red light with
photon energy accounting for 48-57% of total energy and
far infrared light with
photon energy accounting for 8-13% of total energy According to the spectrum formula, a specific spectrum ratio in a visible light range is customized according to a special photosynthetic conversion effect on a spectrum in a specific
wave band range in the
growth cycle of tomatoes, and UV light in a reasonable ratio is added, so that UV light photons play roles in disinfection and sterilization, and synthesis of vitamins, proteins, sugars and acids is promoted. The content of
antioxidant, the yield and quality of tomatoes and the like are improved. The added
far infrared photons play roles in increasing the photon
penetration rate, promoting the photon
photosynthesis efficiency, generating the
heat effect, and providing heat for growth and development of tomatoes, and the problem that tomatoes have poor
spectral absorption and planting effects on an existing
light source is solved.
