Light source device with discharge tube disposed in the neck of a reflector and projector therewith

In a light source device (10), relations of ¸1 ‰¤ Tan -1 (Hd / (2f1)) and T1 < H ‰¤ Hd are established, where a diameter of a circle defining an edge on the neck (121) side of a usable-light reflection area in a reflecting portion (122) of a main reflecting mirror (12) is Hd, a distance between t...

Zusammenfassung:	In a light source device (10), relations of ¸1 ‰¤ Tan -1 (Hd / (2f1)) and T1 < H ‰¤ Hd are established, where a diameter of a circle defining an edge on the neck (121) side of a usable-light reflection area in a reflecting portion (122) of a main reflecting mirror (12) is Hd, a distance between the edge on the neck (121) side of the usable-light reflection area of the reflecting portion (122) of the main reflecting mirror (12) and an emitting center O of an emitting portion (1111) in a central axis direction of the light beam irradiated from the light source device (10) is f1, an opening diameter of a base end in an extending direction of the neck (121) is H, a diameter of sealing portion (1112, 1113) is T1, and an angle formed by lines connecting inflection points (IP1) between the emitting portions (1111) and the sealing portion (1112) with the emitting center of the emitting portion (1111) and the central axis of the light beam irradiated from the light source device (10) is ¸1.
