Abstract
A sealed lamp device may include a discharge lamp burner; a concave mirror opened to a front direction and reflecting radiation light of the discharge lamp burner to the opened side, an optical axis of the concave mirror being aligned with an optical axis of the discharge lamp burner; a hollow casing structure having an opening section in a front side, to which the concave mirror opened out; and a front plate closing the opening section of the hollow casing structure and emitting the radiation light. The hollow casing structure may be made wider than an opening width of the concave mirror, so as to increase a sealed volume occupied by the discharge lamp burner.
