Embodiment

[0021] Example: as attached figure 2 As shown in the figure, this embodiment provides an LED light source module, which includes LED lamp beads uniformly arranged according to a specific ratio. 19% of the LED lamp beads emitting 460nm blue light, 28% of the total number of LED lamp beads emitting 660nm red light, 28% of the total number of 6500K white LED lamp beads, and 16.7% of the total number of emitting 730nm far-infrared light In order to control the proportion of light in various bands in the formula of the light source spectrum by emitting the number of LED lamp beads with different wavelength bands.

[0022] Specifically, in this embodiment, three LED lamp beads 1 emitting UV light and six LED lamp beads 5 emitting far-infrared light are connected in series and arranged in the same row, and the LED lamp beads 1 emitting UV light are arranged at intervals of two The LED lamp beads 5 emitting far-infrared light are evenly arranged, and the three LED lamp beads 1 emitt...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of greenhouse artificial light systems, in particular to a spectrum formula of an LED light source for tomato planting and an LED light source module. Background technique [0002] At present, ordinary plant cultivation is mainly based on fluorescent lamps, mercury lamps, high-pressure sodium lamps and other lamps as the light source, only the combined light source of red and blue light emitted by LED as the main spectrum, obviously lacking the components of UV and infrared spectrum, It is not suitable for tomato planting, resulting in poor absorption of the spectrum by tomatoes, which in turn leads to poor planting effect. With the rapid development of plant factory planting, LED light supplementary light sources have been widely used in indoor plant factories, greenhouses and other plant production and cultivation. Therefore, it is necessary to develop a special spectrum for tomatoes to obtain better qual...
