Title:
ULTRAVIOLET IRRADIATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/129650
Kind Code:
A1
Abstract:
Provided is an ultraviolet irradiation device capable of, without increasing the size of the device, easily visually recognizing whether ultraviolet rays are irradiated or not. The ultraviolet irradiation device has: a power supply unit; a first discharge lamp including a first tube body and emitting ultraviolet rays; a second discharge lamp including a second tube body and emitting a visible light; a first electrode region formed in contact with a partial region on the side of the first tube body or inside the first tube body and electrically connected to the power supply unit; a second electrode region formed in contact with a region separated from the first electrode region on the side of the first tube body and electrically connected to the power supply unit; a third electrode region formed in contact with a partial region on the side of the second tube body or inside the second tube body and electrically connected to the power supply unit; a fourth electrode region formed in contact with a region separated from the third electrode region on the side of the second tube body and electrically connected to the power supply unit; and a light irradiation window for taking out both the ultraviolet rays and the visible light from the same place or separately taking out the respective ultraviolet rays and visible light.
