Claims24
A light source comprising:
- a first housing which forms a space enclosing gas for discharging and housing a luminescent part to generate light within the space;
- a second housing which is connected to the first housing on a one end side and configured to guide the light generated from the luminescent part, to an exit window provided on the other end side;
- and
- a cylindrical member which is fixed so as to be inserted between the exit window of the second housing and a portion connecting the first housing and the second housing, and which has an inner wall surface formed as a reflective surface to reflect the light,
- wherein the second housing is connected so as to be in communication with the first housing on the one end side, and
- wherein the cylindrical member is in contact with the luminescent part in the first housing on the one end side and is inserted in the second housing on the other end side.
