LIGHT EMITTING DEVICE, AND ILLUMINATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a light emitting device improving luminous efficiency, and allowing influence of change of an emission color depending on the temperature of a red light emitting LED element to be reduced by focusing attention on a temperature characteristic of the red light emitting LED element.SOLUTION: This light emitting device 1 is mounted to this illumination apparatus. The light emitting device 1 emits light having a correlated color temperature of 2,400 to 3,600 K, and includes a substrate 2, blue light emitting LED elements 3 and red light emitting LED elements 4 mounted on the substrate 2, and a wavelength converting unit 6. The red light emitting LED element 4 has a luminous intensity of 0.2 to 2.5 times as large as that of the blue light emitting LED element 3 at normal use temperature in a state mounted to the illumination apparatus. The wavelength converting unit 6 is excited by light emitted from the blue light emitting LED elements 3 and converts the light to light having a peak at a wavelength of 500-600 nm.
