Light source device and projection type display apparatus

A light source device comprising:

• a light source accommodating section provided with a story structure comprising a first accommodation story and a second accommodation story;
• a red light that emits red laser light, said red light source being accommodated in said first accommodation story;
• a blue light source that emits blue laser light, said blue light source being accommodated in said first accommodation story;
• a green light source that emits green fluorescence, said green light source being accommodated in said second accommodation story;
• a first light synthesizer that synthesizes an optical path of said red laser light emitted from said red light source and an optical path of said blue laser light emitted from said blue light source into one optical path, and that emits first synthesized light into which said red laser light and said blue laser light are synthesized;
• a second light synthesizer that synthesizes an optical path of said green fluorescence emitted from said green light source and an optical path of said first synthesized light emitted from said first light synthesizer into one optical path, and that emits second synthesized light into which said green fluorescence and said first synthesized light are synthesized;
• and
• a light flux diameter adjusting lens provided on the optical path of said first synthesized light to adjust a light flux diameter of said first synthesized light to a light flux diameter of said green fluorescence.

A projection type display apparatus, comprising:

• first and second light source devices,
• a light synthesizer that synthesizes an optical path of output light of said first light source device and an optical path of output light of said second light source device into one optical path, and that emits illumination light into which the output light of said first light source device and the output light of said second light source device are synthesized,
• an image forming section that modulates said illumination light to form an image, and
• a projection lens that projects the image formed by said image forming section,
• wherein each of said first and second light source devices comprises:
• a light source accommodating section provided with a story structure comprising a first accommodation story and a second accommodation story;
• a red light source that emits red laser light, said red light source being accommodated in said first accommodation story;
• a blue light source that emits blue laser light, said blue light source being accommodated in said first accommodation story;
• and
• a green light source that emits green fluorescence, said green light source being accommodated in said second accommodation story;
• a first light synthesizer that synthesizes an optical path of said red laser light emitted from said red light source and an optical path of said blue laser light emitted from said blue source into one optical path, and that emits first synthesized light into which said red laser light and said blue laser light are synthesized;
• a second light synthesizer that synthesizes an optical path of said green fluorescence emitted from said green source and an optical path of said first synthesized light emitted from said first light synthesizer into one optical path, and that emits second synthesized light into which said green fluorescence and said first synthesized light are synthesized;
• and
• an emission window provided on a side of said second accommodation story, wherein said second light synthesizer emits said second synthesized light toward said emission window.
