摘要 |
To achieve a light-emitting device emitting light with high brightness, closer to natural light, and less color shift due to a small change in intensity of emitted light, in a light-emitting device including a light source emitting light by driving current and at least one wavelength-converting material absorbing at least part of the light from the light source and emitting light having a different wavelength, the color coordinate x 1 (17.5) and the color coordinate y 1 (17.5) of the light emitted at a driving current density of 17.5 A/cm 2 and the color coordinate x 1 (70) and the color coordinate y 1 (70) of the light emitted at a driving current density of 70 A/cm 2 satisfy the following Expressions (D) and (E) : - 0.06 ‰ x 1 17.5 - x 1 70 ‰ 0.06 - 0.06 ‰ y 1 17.5 - y 1 70 ‰ 0.06 |
