ABSTRACT:
A light source device (10) includes a lamp unit (1) and a lamp cartridge (2) in which the lamp unit (1) is housed. The lamp unit (1) includes a discharge lamp (11), a reflection mirror (12) and a transparent plate (13). The reflection mirror (12) has ventilation openings (121). The lamp cartridge (2) has ventilation openings (214, 215and231). Fragment-passage prevention members (30, 31and32) are provided on the ventilation openings (214, 215and231). The fragment-passage prevention members (30) allow the passage of the air but prevent the passage of the fragments of the discharge lamp (11). With such an arrangement, it is possible to prevent the fragments from being scattered out of the lamp cartridge (2), even when the breakage of the discharge lamp (11) occurs.
