The pursuit of perfection by human beings is endless. This sentence is perfect for the car lights.
In the more than 100 years of automotive invention, in addition to the pursuit of faster driving speed, human beings also have a high pursuit in other aspects of the car, such as the lighting.
Originally used in car lighting is not a light, but a gaslight. Because the stability of early electric lights is poor and the brightness is not as good as that of gaslight, gaslight with kerosene as the main energy source are the best choice for automotive lighting. However, gaslight has a very obvious shortcoming and need to be preheated and cannot be lit immediately.
The gaslight has been used for many years until the 1930s when the gaslight was gradually replaced by the electric light, and it was retired.
There are two main reasons why electric lights can replace gaslight.
1. With the development of technology, the stability of electric lights has been solved to a certain extent.2. The electric lights can be lit at any time without delay, and the function of switching between far and near light can be realized by using multiple light groups, which is not only more humanized but also greatly reduces the occurrence of traffic accidents during night driving.
However, the electric light at this time is still an incandescent light, which has low luminous efficiency and short life and needs further improvement.
Halogen light
With the development of technology, an upgraded version of the incandescent light- the halogen light appeared.
The halogen light is filled with a halogen gas such as iodine or bromine in the original incandescent light, which not only greatly increases the life of the filament, but also further saves energy by more than 30%.
For the use of the car lights, the halogen light has sufficient brightness and reliable operation and is the best comprehensive cost-effective product. To this day, halogen lights are still used in most home vehicles and are mostly used in low-end models.
HID xenon light
Human beings will never be satisfied with the current technology and will continue to breakthrough.
In the 1990s, Hella took the lead in successfully transplanting xenon lights to automotive lighting and launched xenon lights.
Xenon lights have higher brightness, lower energy consumption, longer life and many advantages over halogen lights.
The xenon light emits more than twice the luminous flux of the halogen light, and the efficiency of converting electrical energy into light energy is also more than 70% higher than that of the halogen light.
Therefore, the xenon light has a relatively high energy density and light intensity, and the operating current is only half of halogen light. The increased brightness of the lights also effectively expands the visual range in front of the car, creating a safer driving condition.
However, xenon lights are higher in manufacturing cost than halogen lights, so they have only been used in high-end models for a long time. On the other hand, the physical spectrum penetration of xenon lights in general. In foggy weather, halogen lights are still be used in car lighting.
Car LED light
Only after more than ten years of xenon headlights, LED lights have quickly entered people's field of vision.
From the first assembly of LED lights to production cars for more than a decade ago, the manufacturing cost of LED lights has dropped significantly. It is now lower than the manufacturing cost of xenon lights.
It is a representative of next-generation lighting and a future trend.
