Talking about the Development Process of Automobile Lights
In fact, the lights were not born with the car, but they were found in the use of the car to require a lighting device before they could be put into use. However, due to the existence of many unstable factors, the early lights had undergone many improvements. It was not until they entered the incandescent light of the electric age that they officially began to invest in cars. In recent years, the technology of headlights Followed by the models began to stride forward, the current laser headlamps have also been put into production models. Let's talk about the history of car lights. Kerosene lamp era In the first two years of the car's initial use, the device on the lights did not attract everyone's attention. It was not until 1887 when a driver lost his way in the dark wilderness and a farmer took him safely with a portable light to take him home. People realized the importance of the lights. Sex. So later on, people used the reflector and kerosene lamp to make the first lights. Acetylene lamp era Since kerosene lamps have inherent defects, they are quickly eliminated. Then people chose to use the acetylene lamp, but soon discovered that there are many inadequacies in the acetylene lamp. For example, when acetylene is used as a raw material, it must be shaken to keep the headlights lit, when it is raining, it cannot burn, and when it is burned, substances that are harmful to the human body can be produced. Incandescent Times The incandescent filament of the beginning was made of carbon, but it was quickly eliminated because it could not withstand severe jolts. The birth of tungsten light solved the problem of carbon fiber fragility. Since the circuit system was not yet used in cars at the time, the earliest electric car lights were used in electric vehicles, and in 1898 the Colombian electric company launched The first electric car with tungsten filament as a lamp. It was not until 1912 that the electric lights began to be applied to cars. In 1915, a far-and-a-low light that could be adjusted up and down was present. In 1924, OSRAM launched a model that could be used to keep the light far and near. Separate double filaments. Tungsten lamps are replaced by halogen lamps because of the objective factors of blackening. Helium, LED era In 1995, the European law was the first to allow the use of Xenon lamps. However, due to the relatively high cost of Xenon lamps, they were initially applied to some high-end models, and only slowly began to spread. In 2007-2008, LED lights began to be applied. Laser Age With the advancement of the times, science and technology are advancing with each passing day, and therefore LED lights are gradually failing to meet our needs. Therefore, laser headlights have also emerged. The current model that uses the laser headlamp technology is the BMW i8. The above is related to the history of the development of car lights. I hope that we can help you understand the importance of car lights more clearly. Sandwich Panel Machine is a integrated production line consisting of a Roll Forming Machine and a sandwich panel laminating system. The roll forming machine and the laminating system can be operated separately. The roll forming machine consists of decoiler, main body and post-cut equipment. The laminating system consists of feeding, glue, heating, laminating and post-cutting.
The line can produce single corrugated sheet, and can also produce the sandwich panel with rabbet joint and sandwich panel.
The sandwich panel machine has two different systems: Pu sandwich panel machine and EPS sandwich panel machine according the different laminating Technology.
