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

透光率是什么？為什么要求透光率70%？接下來小編為您介紹

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，顧名思義是指光線通過的百分率，透光率越高，即代表車膜的顏色越淺，駕乘人員的視線越清晰。國家交通部規定，前擋車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%.

為什么要求透光率70%？研究表明，人眼的可視距離是隨入射人眼中可見光的減少而降低的，在其他條件不變的情況下，70%可見光透過率是人眼可視距離的一個轉折點。當入射眼睛的可見光在70%以上時可視距離減少得比較慢，當入射眼睛的可見光低于70%時，可視距離急劇下降。

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.

劣質車膜除了會影響車輛本身的視野，也會干擾到其他駕駛員的視線，發生車禍的幾率是合格車膜的數倍。透光率要求70%，是為了提高駕駛員的可視距離，也讓后車可以透過前車看到其他行人或車輛，從而提前快速做出相應的預判與措施。

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.

汽車貼膜透光率有什么陷阱？汽車貼膜后的透光率計算公式是前風擋玻璃透光率與所貼膜透光率的乘積，國家要求的是總體70%透光率，但很多劣質車膜品牌卻偷換概念，把自己的膜定義為透光率為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%.

現在大多數汽車前風擋玻璃的透光率在80%左右,因此汽車膜的透光率至少在80%以上才能使得玻璃貼膜后的總體透光率在70%以上,由此可見市面上銷售的汽車膜中絕大多數汽車膜都是不合格的。

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.

車膜好壞關乎生命，想要避免買到不合格的假冒偽劣車膜，需要認準圣佳這樣可信度高的大品牌。嚴格篩選下的基材決定了非常高的光學清晰度，無論夜晚還是惡劣天氣都能保證駕駛視線始終清晰。

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.
