SHORT WAVELENGTH ULTRAVIOLET DISCHARGE LAMP AND ULTRAVIOLET RAY IRRADIATOR

摘要

The present invention relates to a discharge lamp with a short wavelength ultraviolet light ultraviolet ray irradiation processing apparatus, and an object thereof is coated with a fluoropolymer having an insulated conductor, and, in the discharge lamp to a wavelength of 220nm or less irradiated with ultraviolet rays, and also detrimental to the hydrogen fluoride generating an inhibition of acid and hydrofluoric acid that causes a decrease in the amount of light emitted to the human body. Discharge lamp of the present invention comprises a quartz glass tube 31, both ends of a pair of electrodes disposed on (32a, 32b) and, therefore, a lead wire 60 extending to the outer wall of the quartz glass tube. The lead wire is coated insulated conductor coated with an insulator made of a fluorine resin of the outer layer of a metal member. The lead wire, the ultraviolet is irradiated, but does not touch the UV fluoropolymer characterized in that hydrogen fluoride and hydrofluoric acid is not generated.
