Abstract: A light-emitting plasma lamp bulb for solar ultraviolet simulation includes a bulb cover having a spherical shape or a rod shape through which ultraviolet rays are transmittable, discharge gas contained in the bulb cover, and a first light-emitting material and a second light-emitting material, wherein the first light-emitting material includes at least one of mercury (Hg) and mercury iodide (HgI2), and the second light-emitting material includes sulfur (S8), wherein light emitted from the bulb has a maximum optical power intensity in a range of 395 to 455 nm which is an ultraviolet-visible boundary region, wherein, when compared using a same ultraviolet dose in an ultraviolet region of 290 to 400 nm, an integrated intensity of a visible and infrared region of 400 to 850 nm is equal to or less than ⅕ of an integrated intensity of a visible and infrared region of a standard solar spectrum (ASTM G173, AM 1.5G).
