Abstract (en)

[origin: EP2927931A1] A discharge lamp according to an embodiment includes a light emitting section including, on the inside, a discharge space in which metal halide including halide of indium is encapsulated and a pair of electrodes projecting to the inside of the discharge space and disposed to be opposed a predetermined distance apart from each other. A percentage of the halide of indium included in the metal halide is 0.1 wt% or higher and 0.33 wt% or lower. A dimension "d" of a longest portion of the discharge space in a direction orthogonal to an extending direction of the pair of electrodes in the discharge space is 1.5 mm or more and 2.3 mm or less.
