Many car owners often see one word when considering the automobile film - transmittance.

透光率是什么？为什么要求透光率70%？接下来小编为您介绍

What is the light transmittance? Why 70% light transmittance is required? Next, the editor will introduce

透光率是什么？透光率，顾名思义是指光线通过的百分率，透光率越高，即代表车膜的颜色越浅，驾乘人员的视线越清晰。交通部规定，前挡车膜的透光率一定要高于70%。

What is the light transmittance? Transmittance, as the name suggests, refers to the percentage of light passing through. The higher the transmittance, the lighter the color of the film, and the clearer the vision of the drivers and passengers. According to the regulations of the Ministry of communications, the light transmittance of the front bumper film must be higher than 70%.

为什么要求透光率70%？研究表明，人眼的可视距离是随入射人眼中可见光的减少而降低的，在其他条件不变的情况下，70%可见光透过率是人眼可视距离的一个转折点。当入射眼睛的可见光在70%以上时可视距离减少得比较慢，当入射眼睛的可见光低于70%时，可视距离急剧下降。

Why 70% light transmittance is required? The research shows that the visible distance of human eyes decreases with the decrease of the visible light incident in human eyes. Under other conditions unchanged, 70% visible light transmittance is a turning point of the visible distance of human eyes. When the visible light of the incident eye is more than 70%, the visible distance decreases slowly. When the visible light of the incident eye is less than 70%, the visible distance decreases sharply.

劣质车膜除了会影响车辆本身的视野，也会干扰到其他驾驶员的视线，发生车祸的几率是合格车膜的数倍。透光率要求70%，是为了提高驾驶员的可视距离，也让后车可以透过前车看到其他行人或车辆，从而提前快速做出相应的预判与措施。

Inferior film will not only affect the vision of the vehicle itself, but also interfere with the vision of other drivers. The probability of an accident is several times that of a qualified film. The light transmittance is required to be 70% in order to improve the visual distance of the driver and allow the rear vehicle to see other pedestrians or vehicles through the front vehicle, so as to quickly make corresponding predictions and measures in advance.

汽车贴膜透光率有什么陷阱？汽车贴膜后的透光率计算公式是前风挡玻璃透光率与所贴膜透光率的乘积，要求的是总体70%透光率，但很多劣质车膜却偷换概念，把自己的膜定义为透光率为70%。

What are the pitfalls in the light transmittance of automobile film? The formula for calculating the light transmittance of the automobile after coating is the product of the light transmittance of the front windshield glass and the light transmittance of the film. The national requirement is that the overall light transmittance is 70%. However, many low-quality film brands have secretly changed the concept and defined their own film as having a light transmittance of 70%.

现在大多数汽车前风挡玻璃的透光率在80%左右,因此汽车膜的透光率少在80%以上才能使得玻璃贴膜后的总体透光率在70%以上,由此可见市面上销售的汽车膜中绝大多数汽车膜都是不合格的。

At present, the light transmittance of most automobile front windshield glass is about 80%, so the overall light transmittance of glass after coating can be more than 70% only when the light transmittance of automobile film is at least more than 80%. It can be seen that the vast majority of automobile films sold in the market are unqualified.

车膜好坏关乎生命，想要避免买到不合格的假冒伪劣车膜，需要认准圣佳这样可信度高的大。严格筛选下的基材决定了非常高的光学清晰度，无论夜晚还是恶劣天气都能保证驾驶视线始终清晰。

The quality of car film is related to life. If you want to avoid buying substandard fake and inferior car film, you need to identify a big brand with high credibility such as Shengjia. The strictly selected substrate determines the very high optical clarity, which can ensure the driving line of sight is always clear at night or in bad weather.
