For example, in a plant factory, vegetables and the like are grown by artificial lighting, and it is not impossible to grow turf with artificial lighting. On the other hand, a large-scale natural turf sports yard requires a large-scale lighting facility, and the lighting facility may hinder the use of the sports yard in some cases. In addition, there is a problem that maintenance and maintenance costs become enormous as the lighting facilities become larger,
The indoor natural grass sports yard has not been realized.

る。SUMMARY OF THE INVENTION The present inventor paid attention to a proximity illumination system using a fluorescent lamp, which has been proposed as a plant cultivation system in a closed environment such as a space station. Proximity lighting using fluorescent lamps refers to "a lighting system in which the distance between plants and fluorescent lamps is close to several tens of centimeters, the inner surface is painted white, and the reflected light is used effectively" (CELSS Research Journal, Vol. 5, No.2, Yasuhiro Tanimura, Akira Ikeda, p7-10). Less than,
The proximity illumination method will be described to the extent necessary for understanding the present application.
【０００６】一般に光利用効率を示す係数である照明率
Ｕは次式により定義される。In general, an illumination factor U, which is a coefficient indicating light use efficiency, is defined by the following equation.
【式１】 Ｅ＝（Ｕ・Ｍ・Ｆ）／Ｓ ………(1)[Equation 1] E = (U · M · F) / S (1)
【０００７】ここで、Ｅは被照射面の照度(lx)、Ｍはラ

ができる定数であるから、照明率Ｕが大きくなるに従っ
てランプ全光束Ｆに対する被照射面への入射光束すなわ
ち照度Ｅの割合は高くなる。Here, E is the illuminance (lx) of the irradiated surface, M is the lamp maintenance rate, F is the total luminous flux of the lamp (lm), and S is the area of the irradiated surface (m 2 ). Since the lamp maintenance rate M is a constant that can be set to, for example, 1.0, the ratio of the luminous flux E incident on the irradiated surface to the total luminous flux F of the lamp increases as the illumination rate U increases.
【０００８】一方照明率Ｕは部屋指数Ｋr、ランプ周囲

指数Ｋrは次式により定義される。On the other hand, the illuminance U is strongly affected by the room index Kr, the reflectance ρ of the peripheral surface of the lamp, and the like. For example, the ceiling surface
Ρ 1 (= 0.8) ・ ρ 2 (= 0.8) ・
The relationship between the illumination ratio U and the room index Kr when ρ 3 (= 0.6) can be represented as shown in FIG. Here, the room index Kr of the nursery room with the lamp height H (m), the frontage L (m) and the depth W (m) is defined by the following equation.
【０００９】[0009]
【式２】 Ｋr＝［Ｈ・（Ｌ＋Ｗ）］／（２・Ｌ・Ｗ） ………(2)[Formula 2] Kr = [H · (L + W)] / (2 · L · W) (2)

を低くすれば照明率Ｕを増加させることができる。FIG. 5 shows that the illumination ratio U decreases as the room index Kr decreases.
Equation (2) indicates that the room index Kr and the lamp height H are in a proportional relationship. That is, the lamp height H
Lowering the illumination rate U can be increased.

率を向上させて省電力を図ることができる。When a high-intensity lamp such as a high-pressure sodium lamp is used, the height of the lamp needs to be 1 m or more in order to avoid leaf burning due to infrared radiation. However, if a fluorescent lamp with low infrared radiation (hereinafter sometimes referred to as low infrared radiation) is used, it is possible to avoid leaf burning even if the distance between the plant and the lighting lamp is reduced to several tens of cm. As a result, it is possible to improve light use efficiency and save power.

A low-infrared radiation lamp 2 held on the surface opposite to the surface, and a carbon dioxide gas discharge port 10 held on the support leg 4 or the reflector 1 toward the surface to be irradiated. The length of the support leg 4 is selected so that the distance from the ramp 2 is short enough to prevent leaf burning on the growing grass.

According to the present invention, close illumination with a small lamp height H is performed on a surface to be illuminated having a large frontage L and depth W and a large area. The rate U is obtained. According to the experiment of the present inventor, the illuminance of 30 klx or more is necessary for growing the turf for sports, and the required number of low-infrared radiation lamps 2 is appropriately increased to secure the required illuminance on the irradiated surface. The number of the low-infrared radiation lamps 2 is determined by substituting the area S of the irradiated surface, the lamp maintenance rate M, the illumination rate U, and the required illuminance E (≧ 30 klx) into the above equation (1). F (lm) and luminous flux per lamp (lm / line)
It can be calculated from

に限定されない。The reflection plate 1 is, for example, one in which the surface facing the surface to be irradiated is painted white to increase the reflectance. If the surface to be illuminated is too wide to be covered by one reflector 1, uniform illumination of the turf can be ensured by covering the surface to be illuminated with a plurality of reflectors 1 in a planar manner. The embodiment shown in FIG. 1 shows a reflecting surface 8 which can be flexibly connected to a plurality of reflecting plates 1 having a relatively small area so that they can be developed in a plane. However, the size and shape of the reflection plate 1 can be appropriately selected, and are not limited to the illustrated example.

被照射面の照度の増加が可能である。Further, western turf widely used in turf sports yards and the like is a C 4 plant characterized by a large saturated light intensity indicating an upper limit of the photosynthetic rate. Therefore, it is possible to increase the number of low-infrared radiation lamps 2 and increase the illuminance of the irradiated surface until light saturation is reached, thereby increasing the photosynthesis speed of the turf. The present invention uses the low-infrared radiation lamp 2 and further maintains the distance between the surface to be irradiated and the low-infrared radiation lamp 2 to the extent that leaf scorch does not occur on the turf, so that irradiation can be performed without causing the problem of leaf scorch. The illuminance of the surface can be increased.

きる。Furthermore, if carbon dioxide gas is supplied to the irradiated surface on which the turf grows, photosynthesis of the turf further increases. According to the experiment of the present inventor, it is possible to effectively increase the photosynthesis speed of turf and shorten the illumination time required for turf cultivation by using both high-illuminance illumination and carbon dioxide gas supply. For example, photosynthesis sufficient for grass growth can be ensured by high-illumination lighting and carbon dioxide gas supply only when the sports yard is not used, such as at night.

とはない。Since the illuminating device of the present invention has a high illuminance U of the formula (1), a large illuminance can be efficiently secured by a relatively small number of low-infrared radiation lamps 2. Also, since the irradiated surface and the lamp are brought close to the limit that does not cause leaf burning,
The lighting device can be made small and light enough to be movable. If the lighting device is moved out of the illuminated surface when the lighting is stopped, the lighting device does not hinder the use of the turf sports yard.

Furthermore, if a three-wavelength fluorescent lamp that combines phosphors that emit strong light in the narrow bands of red, green, and blue is used, the three-wavelength fluorescent lamp has an optimal spectral distribution for plant growth. A further increase can be expected.
When a fluorescent lamp is used, the distance between the lamp and the surface to be irradiated can be reduced to several tens cm or less.
