<P>PROBLEM TO BE SOLVED: To provide a light source apparatus for raising plants that can efficiently raise plants without giving displeasure to persons. <P>SOLUTION: The light source apparatus for raising plants includes white LEDs and red LEDs. The color temperature of irradiation light is 2,800-6,500 K, and the ratio of the radiant flux intensity of a wavelength 600-700 nm to the radiant flux intensity of a wavelength 400-500 nm in the irradiation light is in a range of 1.52-4.56. It is preferable that the color temperature of the radiation light of the white LEDs is 4,000-10,000 K. <P>COPYRIGHT: (C)2013,JPO&INPIT |
