| Abstract: | The illumination and appearance of automotive lamps shall be affected severely due to the condensed beads in lamp cover when the water vapour met with cold air.The hot design concept is introduced in the design of automotive lamp and the condensing mechanism,influencing factors and etc.which caused the fogging in the inside of automotive lamp are analyzed.It is noted that the lamp material,the flow field in the lamp,the temperature field and the concentration field distribution are the determinative factors for fogging,some solutions are put forward to give a guidance of optimum automotive lamp design. |
