Problems solved by technology

However, none of the above schemes have been simulated for the high-temperature and high-humidity storage environment of long-distance ocean transportation, and it is impossible to evaluate the risk of fogging when it is used for KD export, after long-distance ocean transportation, and after local assembly and assembly of lights, it is sold and used.

Embodiment Construction

[0013] A test method for detecting anti-fogging performance of automobile headlights, comprising the following steps:

[0014] A) Store the car lamp to be tested in a temperature and humidity box to simulate the storage conditions of the long-distance sea transportation of the KD export car lamp;

[0015] B) Take the lamp to be tested out of the temperature and humidity chamber to confirm the moisture absorption weight;

[0016] C) After confirming the moisture absorption, place the lamp to be tested in a dual-temperature chamber to simulate the ambient temperature when the lamp is in use;

[0017] D) Simulate the high-risk conditions of headlight fogging when the user uses the whole vehicle in the dual temperature chamber;

[0018] E) Observe the fogging of the headlights and the dissipating time, and evaluate the results.

[0019] Simulate the sea transportation temperature and humidity environment through the temperature and humidity chamber to simulate the sea transporta...

Abstract

The invention aims to provide an anti-fogging performance detection test method for an automobile lamp in a long-period marine transportation mode. The marine transportation temperature and humidity environment is simulated through a temperature and humidity box to simulate the KD outlet vehicle lamp marine transportation process, then the peripheral conditions of a whole automobile is simulated through double temperature bins, and finally the automobile lamp fogging working condition when a user uses the whole automobile is simulated; the anti-fogging performance of the automobile lamp can beeffectively detected, evaluated, judged and improved; the test method is convenient, efficient and low in cost.

Description

technical field [0001] The invention relates to the technical field of automobile lamps, in particular to an anti-fogging performance detection test method of automobile lamps. Background technique [0002] KD export of car lights is a common way of car export, that is, the whole car parts are scattered and exported, assembled and sold locally in the target market. This way can effectively save the cost of whole car development brought about by export. For KD export models, based on the transportation cost of automobile lamps, the most common transportation method is sea shipping. The lamps are in the high-temperature and high-humidity environment of sea transportation for a long time, and a large amount of water vapor in the surrounding environment enters the lamps. Secondly, the plastic parts of the car lights will continue to absorb moisture in a high-temperature and high-humidity environment. The above two factors cause the car lights after long-distance sea transportati...
