  • Patent number: 11968937
    Abstract: A light module includes a first light emitter, a second light emitter, a third light emitter, and a controller. The first light emitter is configured to emit a first light having a first peak wavelength in a visible range, the second light emitter is configured to emit a second light having a waveform having a second peak wavelength higher than the first peak wavelength, and the third light emitter is configured to emit a third light having a third peak wavelength that is shorter than the first peak wavelength. The controller is configured to control the first light emitter, the second light emitter, and the third light emitter to generate a first light pattern and a second light pattern. The first light pattern comprises a first light spectrum and the second light pattern comprises a second light spectrum including at least one more peak wavelength than the first light spectrum.

  • Patent number: 11917958
    Abstract: A light source includes a controller configured to turn on or off a plurality of light sources depending on a light period. The controller can be configured to turn on the light sources during each of a plurality of light periods such that the light sources emit a light having a spectrum with a plurality of peaks toward the plant. At least one light period can include a first period and a second period and the first period preceding or following the second period. The controller can adjust the spectrum of the light between the first period and the second period and/or during different light periods.

  • Patent number: 8791394
    Abstract: The present invention is to provide a heating substrate equipped with a conductive thin film and electrodes. The heating substrate includes a transparent substrate, a plurality of electrodes formed on a first face of the substrate, and a conductive thin film formed on the first face of the substrate and including a plurality of regions electrically connected each other in parallel by the plurality of electrodes. Furthermore, a method of manufacturing a heating substrate equipped with a conductive thin film and electrodes according to an exemplary embodiment of the present invention includes forming the conductive thin film on a substrate, forming main electrodes so as to extend on the substrate while being adjacent to edges of the conductive thin film, and forming branched electrodes that are extended from the conductive thin film across one side of the conductive thin film while coming in contact with the conductive thin film.
