LIGHTING DEVICE AND IMAGE DISPLAY DEVICE |
| 摘要 |
This lighting device comprises a laser light source, a phosphor having a yellow phosphor that is excited by the laser light source, and a color filter on which fluorescent light emitted from the phosphor is incident. The color filter has first and second segments with different transmission spectrums, the first segment transmitting the entire wavelength band of yellow fluorescent light emitted from the yellow phosphor, and the second segment removing the short wavelength component of the yellow fluorescent light. |
