In automotive lighting technology, fog lamps are key components for dealing with bad weather, and their stability is crucial. The material selection of fog lamp glass covers plays a decisive role in the long-term stable operation of fog lamps. Borosilicate glass, with its unique low expansion coefficient characteristics, has become the preferred material for fog lamp glass covers.
The biggest highlight of borosilicate glass is its extremely low thermal expansion coefficient. This feature is crucial for fog lamp glass covers, because it means that under drastic temperature changes, the glass cover can maintain a high degree of dimensional stability and is not prone to stress or deformation due to thermal expansion and contraction.
Fog lamps are often used in extreme weather conditions and need to face drastic temperature changes from extreme cold to hot summer. Traditional glass materials are prone to stress when the temperature changes due to their large thermal expansion coefficient, causing the glass cover to break or the sealing performance to decrease. The low expansion coefficient of borosilicate glass effectively solves this problem. Regardless of cold or heat, the original shape and size of the glass cover can be maintained to ensure that the lighting effect and sealing performance of the fog lamp are not affected.
In addition to the low expansion coefficient, the heat resistance of borosilicate glass is also one of the important reasons why it is so popular. During the operation of the fog lamp, due to the heat generated by the bulb, the 19-A277-05 Smooth and glossy auto fog lamp glass coverwill be subjected to the test of high temperature environment for a long time. Borosilicate glass has extremely high heat shock resistance, which means that it can withstand drastic temperature changes in a short period of time without breaking. This excellent heat resistance ensures that the fog lamp can still maintain a stable lighting effect after long-term use, and will not cause the glass cover to deform or break due to high temperature, thereby affecting the normal operation of the fog lamp.
Further, the heat resistance of borosilicate glass is also reflected in its ability to withstand high temperature environment for a long time without performance degradation. In some extreme cases, such as vehicles driving in high-temperature areas for a long time or fog lamps working continuously for several hours, traditional glass materials may gradually lose their original transparency and strength due to high temperature. However, borosilicate glass can maintain its stable performance in such high temperature environment, ensuring that the fog lamp can always provide clear lighting effects.
Borosilicate glass also has the advantages of high light transmittance and strong chemical stability. Its high light transmittance ensures that the fog light can fully penetrate the thick fog, providing the driver with a clear view; its strong chemical stability makes the glass cover less susceptible to corrosion by acids, alkalis and other chemical substances, thus extending its service life.
