Description

technical field [0001] The invention belongs to the field of ultraviolet lamp driving. Background technique [0002] Ultraviolet lamp manufacturers lack a scientific method for formulating rated power, and they are often formulated according to the method of fluorescent lamps. If the driver or ballast developer drives the ultraviolet lamp according to this power, the irradiance of ultraviolet rays in the required spectrum may be insufficient, or The filament current is too large, and the irradiance decays too quickly. [0003] The driver or ballast developer is an electrical engineer, and only design parameters according to the rated power, either the effective spectral irradiance is insufficient, or the decay rate is fast, reducing the effective life of the UV lamp. [0004] The short-wave ultraviolet light generated by the ultraviolet lamp has the functions of biological inactivation and sterilization, and the ultraviolet sewage treatment method does not produce any harmf...
