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%.

摘要： A light emitting device comprises: an LED chip mounted in a recess formed in a mounting substrate; a wavelength converting member that is disposed so as to cover the recess and the edge area around the recess and that is excited by light emitted from the LED chip to emit light of a wavelength different from an excitation wavelength; and an emission control member disposed at a light output side of the wavelength converting member so as to allow emission of light coming from an area of the wavelength converting member that corresponds to the recess and to prevent emission of light coming from an area of the wavelength converting member that corresponds to the edge area around the recess. This can prevent variations in color between light emitted from the central part of the wavelength converting member and light emitted from the part of the wavelength converting member that is located on the edge area around the recess of the mounting substrate, thereby reducing unevenness of color on the irradiation surface.

摘要： In a photometry device, photopic vision luminance Lp is measured by a first luminance measuring unit including a first light filter 4 and a first photoelectric converter 5, and scotopic vision luminance Ls is measured by a second luminance measuring unit including a second light filter 6 and a second photoelectric converter 7. A calculation part 8 calculates mesopic vision luminance Lmes based on a measurement value (photopic vision luminance Lp) of the first luminance measuring unit and a ratio of a measurement value (scotopic vision luminance Ls) of the second luminance measuring unit to the measurement value (photopic vision luminance Lp) of the first luminance measuring unit. Consequently, the photometry device can improve measurement accuracy of the brightness (mesopic vision luminance) in mesopic vision.
