摘要： A light emitting device (1) includes a LED chip (10) as well as a mounting substrate (20) on which the LED chip (10) is mounted. Further, the light emitting device (1) includes a cover member (60) and a color conversion layer (70). The cover member (60) is formed to have a dome shape and is made of a translucency inorganic material. The color conversion layer (70) is formed to have a dome shape and is made of a translucency material (such as, a silicone resin) including a fluorescent material excited by light emitted from the LED chip (10) and emitting light longer in wavelength than the light emitted from the LED chip (10). The cover member (60) is attached to the mounting substrate (20) such that there is an air layer (80) between the cover member (60) and the mounting substrate (20). The color conversion layer (70) is superposed on a light-incoming surface or a light-outgoing surface of the cover member (60).

摘要： An illumination device includes an irradiation unit having a light emitting element and fluorescent bodies excited by the light from the light emitting element to radiate light of different wavelengths. The irradiation unit irradiates composite light of blue, green and red lights having half value widths of 20-40 nm, 110-150 nm and 80-110 nm and peak wavelengths of 440-465 nm, 545-555 nm and 630-650 nm, respectively. If the output value of the light in a wavelength 435-465 nm is assumed to be 100%, the output values of the lights having wavelengths of 490, 530 and 639 nm fall within 46-56%, 59-77% and 75-93%, respectively. The ratio of the output value of the light of 630 nm to that of the light of 530 nm falls within 73-86%.
