PURPOSE:To supply effectively an optical energy of high quality, which is suitable for growth of plants, to plants by arranging many transparent cylinder bodies, each of which incorporates an optical means, in a grating. CONSTITUTION:A light source device is provided with cylinder bodies 10xl-10xn arranged in parallel in the transverse direction, a cylinder bodies 10yl-10ym arranged in parallel in the longitudinal direction, photoconductors 20xl-20xn and 20yl-20ym for supply of the light into individual cylinder bodies, and optical means 30xl-30xn and 30yl-30ym arranged movably in individual cylinder bodies. Optical means are moved in cylinder bodies to discharge th light, which is introduced from photoconductors 20 into cylinder bodies, under cylinder bodies. Plants are planted under light radiators arranged in a grating in this manner, and light radiators are lowered and the light source approaches plants while plants are small, thus growing plants effectively. |
