WHITE LIGHT EMITTING DEVICE FOR THE PLANT CULTIVATION

摘要

PURPOSE: An LED device expressing useful white light for plant cultivation is usefully applied to not only the plant cultivation but also indoor interior by examining the white light and a red light of 660nm wavelength range suited for the cultivation and growth acceleration of the plant and a blue light of 460nm wavelength range. CONSTITUTION: A blue LED is mounted in a Base substrate. The blue LED has the wavelength range of 440~460 nm. An epoxy or molding liquid of silicone base is spreading in the blue LED. The yellow fluorescent material has the wavelength range of 550~600 nm. The red-emitting phosphor has the wavelength range of 650~670 nm.
