Abstract

Disclosed is a light quality control apparatus for crops, capable of ensuring installation, expand and maintenance of a light source, and improving crops growth and seeds collection. According to a demonstration embodiment of the invention, the light quality control apparatus for crops includes a plurality of LEDs arranged in a module mode to control light radiation angles appropriately, and mounted on a support so as to connect a plurality of light quality control apparatus units by a connector easily. The support is in a shape with at least 16 faces so as to improve manufacturing convenience and irradiate crops equably without shade areas. Furthermore, according to another demonstration embodiment of the invention, the light quality control apparatus for crops is capable of transmittingred light of 660 nm wavelengh to activate phytochrome as photoreceptor protein, so as to control the crops growth, compared with other apparatus, the light quality control apparatus saves 60%-86% electric charge and reduces production costs. For example, if the crops is irradiated by light having at least 0.2 [Mu]mol m<-2>.s<-1> strength, the crops photosynthesis may be improved, such that the crops growth is accelerated. For purple perilla, the light having at least 0.177 [Mu]mol m<-2>.s<-1> strength and 660 [Mu]m wavelengh may restrain the flowering of the crops to ensure the dependable upgrowth of the crops.

[0003] Embodiments of the present invention relate to farm-scale light quality control devices for crops that include red light emitting diodes to promote crop growth. Background technique

[0004] Light is the source of energy for plant photosynthesis and a source of information on photoperiodic phenomena and photomorphogenesis as well as day length effects. In light radiation to plants, the photomorphogenesis of plants and the distribution of photosynthetic products are affected by the ratio of red / far-infrared light, as reported by Kasperbauer in...
