た。 In recent years, so-called plant factories, which cultivate plants by completely controlling cultivation conditions including light, have attracted attention, and their practical application is being considered. Because plant factories completely control environmental conditions, they offer many advantages that cannot be obtained in the natural environment, such as high quality and year-round cultivation. On the other hand, when trying to grow plants under artificial lighting, lighting power costs become a problem because they account for a large portion of the cultivation costs. In particular, the high cost of lighting, which accounts for a large portion of variable costs, is a problem, and efforts have been made to reduce the radiant energy intensity of lighting as much as possible in order to reduce lighting power costs as much as possible.

However, when cultivating at this low radiation intensity, using a lamp with a spectral distribution that is said to be effective for photosynthesis by intensifying the conventional blue and red components of light, the growth of the plant will be affected in terms of quality such as shape and firmness. There was a problem that made it unique. For example, when Western vegetables such as salad greens and sunny lettuce are grown at low radiation intensity under completely controlled environmental conditions, the leaves tend to be elongated and elongated compared to those grown at low radiation intensity. There was a problem in that the hardness decreased and the material became soft, making it impossible to reduce the radiation intensity below a certain level.

In FIG. 2, the fluorescent lamp 4 consists of a glass tube 6 with a phosphor coating 5 on its inner surface, and has electrodes 7 at both ends.
The inside is filled with mercury vapor and inert rare gases such as argon and neon, and has the same structure as a general fluorescent lamp. Reference numerals 8 and 9 are lead-in wires that support the electrode 7 and are sealed to the end of the glass tube 6.
Reference numerals 10 and 11 indicate a cap 1 fixed to the end of the glass tube 6.
This is a connecting pin that is insulated and attached to the lead-in wires 8 and 9, and the ends of the lead-in wires 8 and 9 are connected. This phosphor coating 5
The phosphor components that make up the phosphor include: 15% europium-activated strontium and barium chlorophosphate phosphors that emit mainly blue components, 8% europium-activated strontium borophosphate phosphors, and manganese that mainly emit green components. The composition consists of 7% activated silica-dispersed zinc phosphor, 30% europium-added yttrium oxide phosphor that emits mainly red components, and 40% tin-activated strontium/magnesium phosphate phosphor.
Fluorescent lamp 4 was manufactured. The spectral energy distribution of this lamp is shown in Figure 3, and the spectral energy ratio is 31% for the blue component between 400 and 500 nm, 30% for the green component between 500 and 600 nm, and 30% for the green component between 500 and 600 nm.
~700nm red component is 39%, and the wavelength is
The radiation efficiency of the lamp between 400 and 700 nm was 0.198 W/lamp W for a 20 Watt type lamp. This example lamp and conventional lamps manufactured for plant cultivation have blue component light with wavelengths between 400 and 500 nm and 600 and 700 nm.
Salad vegetables were grown under a completely controlled artificial environment with various irradiation intensities using a lamp that increased the red component light between 500 and 600 nm compared to the green component light between 500 and 600 nm. The cultivation environment conditions are temperature 22±1℃, relative humidity 70±2,
%CO 2 temperature was 1000±500 ppm, and the solution temperature was 22±1° C. 21 days after sowing, the seeds were transferred to a forced cultivation room, and cultivation comparisons were performed under continuous irradiation for 24 hours. Figure 5 shows the results.

成できる。 In Figure 5, the ○ mark means that it is appropriate, the △ mark means that there is a slight problem, and the × mark means that there is a problem.When the irradiation intensity is high, conventional lamps can obtain appropriate elongation and softness. However, when it becomes low, problems arise. On the other hand, when the irradiation intensity is high, the lamp according to the embodiment of this other invention becomes somewhat excessive in elongation and softness, resulting in a somewhat hard and rounded shape, but when the irradiation intensity is low, it does not allow proper growth. Moreover, if it is too low, there will be a lack of energy, the growth will be elongated, and the growth rate will be reduced. Therefore, the lamp according to an embodiment of this other invention is used for cultivation under low irradiation conditions that are advantageous in terms of power saving compared to conventional lamps, that is, in the range of photon irradiation intensity of 80 to 155 μE/m 2 ·s. suitable for. In addition, the radiant energy efficiency in the wavelength range of 400 to 700 nm is also higher than that of conventional lamps, which is 0.176W/lamp W for a 20 Watt type lamp.
It is 0.198W/lamp W, which is advantageous in terms of power saving.

うるという効果がある。 According to Example 1 of this invention, the irradiation conditions for plants are such that the ratio of irradiation energy between wavelengths of 400 and 700 nm is 30±5% between 400 and 500 nm, and 30±5% between 500 and 600 nm. ~700nm is 40±5%, and the irradiation light quantum intensity to the cultivated plants is 80~155μE/
m2・s, the spectral energy ratio of the light was selected to correspond to the photosynthesis mechanism, morphology, and formation mechanism of plants when the irradiation energy of light is low. This has the effect of allowing good plants to be cultivated under any conditions, and reducing power costs when cultivating plants in an artificial environment.

に目標を達成できた。Example 2 As Example 2, fluorescent lamps were manufactured in which the composition ratio of the phosphor used in Example 1 was varied, and the proportions of blue, green, and red components with wavelengths of 400 to 700 nm were varied. A cultivation test similar to 1 was conducted.
As a result, when the irradiation energy ratio irradiated to the cultivated plants was 25 to 35% for 400 to 500 nm, 25 to 35% for 500 to 600 nm, and 35 to 45% for 600 to 700 nm, the same results as in Example 1 were obtained. Good results were obtained. Also, the wavelength is 400
A lamp with a radiant energy efficiency of 0.18 W/lamp W between 600 nm and 600 nm could achieve the target with lower power consumption than conventional lamps.
