Abstract
A light source module for plant cultivation includes a main light source, an auxiliary light source unit, and a controller. The main light source unit emits background light which is visible light for growth of a plant. The auxiliary light source unit emits auxiliary light including UVB, UVC, or both to increase the content of phytochemicals in the plant. The controller controls operation of the main light source unit and the auxiliary light source unit based on a control signal.
Claims21
A light source module for plant cultivation, comprising:
- a main light source unit emitting background light, the background light being including visible light for growth of a plant;
- an auxiliary light source unit emitting auxiliary light comprising UVB, UVC, or both to increase content of phytochemicals in the plant;
- and
- a controller controlling operation of the main light source unit and the auxiliary light source unit based on a control signal,
- wherein the control signal contains information about conditions of the auxiliary light for increase in content of a target phytochemical among the phytochemicals to a predetermined level,
- the conditions of the auxiliary light are indicative of a type and a cumulative dose of the auxiliary light corresponding to the predetermined level of the target phytochemical.
19-20. (canceled)
A light source module for plant cultivation, comprising:
- a main light source unit emitting background light, the background light including visible light for growth of a selected plant, the selected plant comprising sprout ginseng;
- an auxiliary light source unit emitting auxiliary light comprising UVB, UVC, or both to increase content of phytochemicals in the plant;
- and
- a controller controlling operation of the main light source unit and the auxiliary light source unit based on a control signal,
- wherein the control signal contains information about conditions of the auxiliary light for increase in content of a target phytochemical among the phytochemicals to a predetermined level;
- the target phytochemical comprising ginsenoside, one selected from ginsenoside ingredients comprising Rg1, Re, Rc, Rb2, Rd, Rb1, and Rb3, or a combination of the ginsenoside ingredients;
- and
- the conditions of the auxiliary light determining a type and a cumulative dose of the auxiliary light corresponding to the predetermined level of the target phytochemical.
A light source module for plant cultivation, comprising:
- a main light source unit emitting background light, the background light supplying a first type of light for growth of a selected plant during a light period;
- an auxiliary light source unit emitting auxiliary light supplying a second type of light for increasing content of a target phytochemical in the selected plant to a predetermined level;
- and
- a controller controlling operation of the main light source unit and the auxiliary light source unit by:
- determining a type of light to be emitted;
- determining an emission duration of the first type of light, the second type of light, or both;
- determining a first cumulative dose of the first type of light;
- and
- determining a second cumulative dose of the second type of light;
- wherein the target phytochemical comprises ginsenoside, one selected from ginsenoside ingredients comprising Rg1, Re, Rc, Rb2, Rd, Rb1, and Rb3, or a combination of the ginsenoside ingredients.
