ILLUMINATION DEVICE |
| 摘要 |
Provided is an illumination device containing a light source configured to emit an excitation light, a phosphor layer containing a phosphor and configured to allow the excitation light of the light source to be transmitted and emitted therethrough, and a coating film formed by applying a paint containing a pigment and mica and configured to allow the emitted light of the phosphor layer to be transmitted and emitted therethrough, in which the coating film has a light transmission spectrum having a peak wavelength located between a peak wavelength of an emission spectrum of the light source and a peak wavelength of an emission spectrum of the phosphor layer. |
