A method for increasing the yield of a flowering plant includes positioning a lighting device with respect to a lower minor height of the flowering plant. The method includes irradiating the lower minor height with light in a predetermined range of the electromagnetic spectrum for a duration of a flowering stage of a life cycle of the flowering plant. The lighting device may be an annular clamshell design that circumscribes a stalk of the flowering plant. Such a design may be clamped to the stalk via a spring force of a pair of spring-loaded clamps. The lighting device may include a plurality of red LEDs arranged in an arcuate manner. At least 80 percent of the light from the lighting device is in the predetermined range of 580 nm to 780 nm, and may be in the range of 600 nm to 700 nm.

The present invention provides an illuminating device that makes it possible to reduce the number of members for regulating a polarization state and can irradiate light having natural color shades without decreasing energy efficiency of light irradiation, and a plant growth regulation method using the illuminating device. The illuminating device of the present invention includes a light-emitting light source and a polarization state regulation member that regulates a polarization state of the light-emitting light source, in which the polarization state of a wavelength region of a portion of emission wavelengths is changed to circular polarization, and a degree of circular polarization of light in a wavelength band for regulation among the light rays to be irradiated is 0.3 or higher. In a preferable embodiment, a width of at least one wavelength band for regulation of the polarization state regulation member is from 60 nm to 250 nm.
