Natural turf rearing lighting device for stadium and stadium display device with natural turf rearing lighting device

摘要

[Problem] To provide a lighting apparatus for stadium lighting and natural turf growth, and a stadium-use display apparatus equipped with a lighting apparatus for natural turf growth, used in a stadium such as a soccer field, a baseball field, a golf course, and a large-scale stadium. The apparatuses may be normally used as lighting and display apparatuses in such a stadium, and may help natural turf damaged by a sports match recover at a pace faster than a typical natural recovery speed. [Solution] The lighting apparatus comprises a light source operating in a light emitting wavelength range of full colors and including red, green and blue light emitting devices arranged at regular intervals, wherein a main body can be erected and moved. In general, the lighting apparatus functions as a stadium lighting apparatus in an erected state, and casts light of the light emitting devices toward natural turf of a certain location in a laid state to function as a lighting apparatus facilitating natural turf growth and promoting the recovery of natural turf. In order to operate the lighting apparatus for growing natural turf in a stadium such as a soccer field, the wavelength of red light of the light emitting device is set to a range between 650 nm and 670 nm, and the wavelength of blue light is set to a range between 460 nm and 480 nm.
