Problems solved by technology

[0003] The light source in the pulsed light sterilization device needs to work in a flickering state, and its working voltage is generally between 2800V-3600V. Generally, a xenon lamp is used, but even if a xenon lamp is used, this light source is relatively easy to age or damage, and Under normal use, the lifespan is about three months, and if the light source is aged or damaged, the light intensity will be weakened, which will affect the sterilization effect. Therefore, there is an urgent need for a pulse light attenuation test that can measure the light intensity of this pulse light source. circuit, when the light intensity is low, it will alarm and prompt to replace the light source
The light attenuation test circuit in the prior art generally measures the intensity of continuous light, such as the light source we use for lighting, etc. There is no pulse light attenuation test circuit and test method that can test the intensity of pulse light

Abstract

The invention provides a pulsed light attenuation test circuit and method capable of testing the pulsed light intensity. After the pulse width amplification is carried out on a millisecond pulse width signal output by a voltage comparing module, the millisecond pulse width signal is detected through a processing output module, and whether the intensity of the pulsed light reaches the set value or not can be accurately detected; wherein if not, an alarm is given, a user is reminded to replace a light source, and the circuit is very easy to achieve.

Description

technical field [0001] The invention relates to the technical field of sterilization, in particular to a pulse light attenuation test circuit and a test method for a pulse light sterilization device. Background technique [0002] Pulsed light technology is a technology that can release high energy in the form of light radiation in a very short period of time (tens to hundreds of microseconds), thereby generating extremely high peak power (up to megawatts, which reaches the bottom surface) 100,000 times the intensity of sunlight), pulsed light sterilization is to use high-energy ultraviolet rays in pulsed light to destroy microorganisms to sterilize, which is a green, energy-saving and efficient sterilization method. [0003] The light source in the pulsed light sterilization device needs to work in a flashing state, and its working voltage is generally between 2800V-3600V. Generally, a xenon lamp is used, but even if a xenon lamp is used, this light source is relatively easy...
