| titleOfInvention | Light emitting device, illumination device and plant cultivation method |
| abstract | Provided are a light emitting device and an illumination device. The light emitting device is provided with a light emitting element having a light emission peak wavelength in a wavelength range of 380 nm or more and 490 nm or less, a first fluorescent material which is excited by the light from the light emitting element to emit light having at least one light emission peak wavelength in a wavelength range of 580 nm or more and less than 680, and a second fluorescent material which is excited by the light from the light emitting element to emit light having at least one light emission peak wavelength in a wavelength range of 680 nm or more and 800 nm or less, wherein a ratio R/B of a photon flux R of red light in a wavelength range of 620 nm or more and less than 700 nm to a photon flux B of blue light in a wavelength range of 400 nm or more and 490 nm or less is more than 4 and 50 or less, a ratio R/Fr of the photon flux R to a photon flux Fr of far-red light in a wavelength range of 700 nm or more and 780 nm or less is 0.1 or more and 10 or less, and the second fluorescent material contains at least one fluorescent material selected from the group consisting of a first aluminate fluorescent material and a second aluminate fluorescent material. |
