LIGHT SOURCE UNIT AND PROJECTOR |
| 摘要 |
A small light source unit is provided which emits lights of the primary colors which are highly bright and which have a high color reproducibility and excitation light, and the light source unit includes a light source module and a light source control module and the light source module has a first light source which emits light having a first wavelength which is used as excitation light which excites a luminescent material, and a second light source which emits light having a second wavelength which is different from the first wavelength but which falls within a range of wavelengths of light of a similar color to that of the light of the first light source, and the light source control module controls individually the illumination of the first light source and the second light source. |
