UV DISCHARGE LAMP FOR PHOTOCATALYST

摘要

PROBLEM TO BE SOLVED: To provide a UV discharge lamp for a photocatalyst capable of effectively irradiating UV of 300 to 450 nm wavelength which activates the photocatalyst. SOLUTION: This UV discharge lamp wears onto the outer surface of the lamp made of a UV transmitting glass one or more fluorescent substances emitting UV light having 400 nm or shorter wavelength which activates a photocatalyst.
