A control system and method for an automobile disinfection lamp

Abstract

The invention discloses a control system and method for an automobile disinfection lamp. The system is powered by a vehicle-mounted storage battery and includes an ECU control unit, a disinfection lamp, a reading lamp, a power supply for the reading lamp, a control signal superposition circuit and a built-in control circuit for the lamp. The disinfection lamp is installed on The reading light of the car uses the same power supply as the reading light in the reading light, and the installation is simple; the control signal superposition circuit is controlled by the output signal of the ECU control unit. Only when the opening conditions of the disinfection light are met, the control signal superposition circuit can The disinfection lamp control signal will be output, and the built-in control circuit of the lamp controls the power supply of the reading lamp to supply power to the disinfection lamp, and the disinfection lamp is turned on. The invention has a large disinfection area and a small occupied space, is directly powered by a reading lamp power supply, is convenient to use, is controlled by an automobile ECU control unit, and has high reliability.

Description

technical field [0001] The invention relates to a disinfection lamp control system, in particular to an automobile disinfection lamp control system and method. Background technique [0002] The degree of human settlements increases, and the risk of germs and viruses damaging human health is getting higher and higher. In order to reduce the risk of epidemic transmission, cut off the transmission routes of viruses and germs, and regularly disinfect the places where humans frequently move, it has become a necessary method. UV radiation can effectively kill harmful bacteria and viruses. This is why many ultraviolet disinfection lamps are on the market. [0003] With the popularity of cars, people spend more and more time in cars, so it is an urgent need for car owners to disinfect the interior of the car. Therefore, there are also many products that are specially designed for ultraviolet disinfection of the car interior environment. These products can be made into rechargeabl...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a car disinfection lamp control system for the problems of small irradiation area, troublesome charging, space occupation and low accuracy of judging whether there is someone in the car in the prior art. The car reading light is installed in the same lampshade, and by adding a circuit connected to the car electronic ECU (Electronic Control Unit) control unit, the switch between the disinfection light and the reading light is realized, which saves space and improves the accuracy of judging whether there are people in the car
