Abstract

The invention provides an electronic ballast experiment platform for driving an ultraviolet lamp and an optimization method of the driving power of the ultraviolet lamp. The problems of a short service life of the ultraviolet lamp and low short-wave ultraviolet irradiation and low light efficiency caused by a condition that an existing platform for verifying an ultraviolet lamp can not accuratelyset the optimum rated power of the ultraviolet lamp are solved. The electronic ballast experiment platform comprises an EMI filter, a full bridge rectifier, a power factor correction circuit, a half-bridge LCC resonant circuit, a single-chip microcomputer, a driving circuit, a DC filter, a current collection device, a voltage collection device, a black box, a UVA measurement instrument, a UVB measurement instrument, a UVC measurement instrument and a visible light measurement instrument. The platform can be set for the rated power of all lamps, through the platform, the lamp input power is adjusted within a wide range, a variety of test instruments is used to test the irradiation and filament current of each spectrum of the lamp under different power, and thus the irradiation of the lamp under optimum input power is determined. The electronic ballast experiment platform and the optimization method are mainly used for optimizing the rated power of the ultraviolet lamp.

Description

technical field [0001] The invention belongs to the field of ultraviolet lamp driving. Background technique [0002] Ultraviolet lamp manufacturers lack a scientific method to formulate the rated power, and often formulate it 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 band may not be enough, or The filament current is too high and the irradiance decays too fast. [0003] The driver or ballast developer is an electrical engineer. If the parameters are designed only according to the rated power, the irradiance of the effective spectrum band will be insufficient, or the attenuation speed will be fast, which will reduce the effective life of the UV lamp. [0004] The short-wave ultraviolet rays produced by ultraviolet lamps have biological inactivation and sterilization effects, and the ultraviolet sewage treatment method will no...
