Abstract：Fogging in automotive lamps is a common natural physical phenomenon and a critical challenge in the automotive lighting industry.This paper addresses the lamp fogging issue by analyzing the fogging mechanism and evaluating the strengths and weaknesses of conventional anti-fogging solutions.An electrochemical dehumidification strategy based on electrochemistry is proposed.Through analyzing the dehumidification characteristics of the electrochemical dehumidifier and the sources of water vapor in lamps,dehumidification performance tests and whole-lamp fogging comparative experiments were conducted.The results verify the anti-fogging performance of the electrochemical dehumidifier under common fogging conditions.The experimental findings demonstrate that the electrochemical dehumidifier offers distinct advantages over traditional anti-fogging solutions for automotive lamps.
