LIGHTING SYSTEM FOR STADIUM LIGHTING AND NATURAL TURF GROWTH, AND STADIUM DISPLAY APPARATUS EQUIPPED WITH LIGHTING SYSTEM FOR NATURAL TURF GROWTH

摘要

PROBLEM TO BE SOLVED: To provide a lighting system for stadium lighting and natural turf growth, and a stadium display apparatus equipped with the lighting system for natural turf growth, normally usable as a lighting system and a display apparatus in a stadium and attaining the improvement and repair of natural turf damaged by sports matches, faster than a normal natural repair speed.SOLUTION: The lighting system 1 includes a light source comprising red, green and blue light emitting elements arranged at constant spaces and belonging to a light emitting wavelength band with a full color display function, wherein skeletons 2 can be put in derricking motion while being movable, and normally function in an erected state as the lighting system in the stadium and function, in the laid state, as the lighting system for natural turf growth by irradiating natural turf in specific positions with light from the light emitting elements to attain the growth promotion and repair of natural turf. In order to operate the lighting system to function as the lighting system for natural turf growth, the wavelength of red light of the light emitting element is set to 650-670 nm, and the wavelength of blue light is set to 460-480 nm.
