Patents by Inventor Yoon Seon CHOI

Yoon Seon CHOI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240147915
    Abstract: A light source for plant cultivation includes at least two light emitting devices supplying light to a plant. Each of the light emitting devices includes a first semiconductor layer doped with a first conductivity type dopant, a second semiconductor layer disposed on the first semiconductor layer and doped with a second conductivity type dopant different from the first conductivity type dopant, and an active layer interposed between the first semiconductor layer and the second semiconductor layer. The light emitting devices emit light towards the plant under a different condition in terms of at least one of wavelength, radiation intensity, and emission timing to control the type and content of phytochemicals in the plant.

  • Publication number: 20230247944
    Abstract: A light source module for plant cultivation and a light source device including the same. The light source module changes a phytochemical content in a plant through UV treatment of the plant. The light source module may include: a first light source emitting a first type of light changing the content of at least one of multiple phytochemicals; and a second light source emitting a second type of light changing the content of at least one of the multiple phytochemicals. The at least one phytochemical changed in content by the first type of light may be a different kind of phytochemical from the at least one phytochemical changed in content by the second type of light. The first light source and the second light source may be individually operated. In addition, the first type of light and the second type of light may be UV light having different peak wavelengths.
