Car Model - The Historical Evolution of Lamp（A）

From 1885 the German Karl Fitz (Karl Friendich Benz) invented the car, the lights in the history of 100 years of continuous evolution. From chemical lights to electric lights, lights from incandescent, halogen, xenon lights, LED lights, laser lights to OLED lights. TT diecast model below to talk to you about the development of car headlamps.
Candles, kerosene lamp era: 1886 - 1940
When the car was born, almost no features are not, let alone talk lights. It is said that in 1887, when a driver lost his way in the dark wilderness, he was a civilian portable light to lead him home. This is also known as the oldest lighting tool on the car.
Acetylene Lamp: 1905 - 1925
However, because of the low luminous efficiency of the reason, kerosene lamp was soon replaced by acetylene lamp. Some people may be questioned, as early as 1879 incandescent lamp has been invented why the acetylene lamp will be pre-board application in the car? This is because the vacuum incandescent bulb filament is made of carbon wire, too fragile filament can not afford the bumps on the road, can not be applied to the lights. Relatively mature and stable acetylene lamp became the first choice of vehicle headlights, but the disadvantage is that once the car stopped, the production of acetylene will reduce the lights will gradually darken, and burning light of acetylene is easy to be on the road rain water , Driving in bad weather has become the driver's nightmare.
Incandescent: With the development of electric lights, the durability of the upgrade, acetylene lamp together with its shortcomings gradually out of the history of the stage of the lights. Replaced by the increasingly mature incandescent lamp. Spiral tungsten filament incandescent lamp compared to the original carbon filament incandescent light intensity increased by 50%. Spiral tungsten filament incandescent lamp can be said to really start the history of the development of automotive lighting electrification, before the kerosene lamp and acetylene is considered a wild history it.
See here is not it strange? Car lights history so short? Hey ~ of course it is impossible to give you a small suspense, tomorrow to answer, forgive me here brought back your greedy insects, and temporarily can not answer for you, but to be continued ... ...

Car model appreciation

The proportion is the most basic, different proportions of the production process and the number of spare parts are also very different. Followed by the details of the same static simulation of the car model , the details of the difference is enough to form a huge difference between the products, naturally also formed a huge difference between the price of the brand. How to go through the details to identify the quality of the car model quality and grade of the level of the following methods can let you have a basic way to identify: weigh the weight, guess parts, paint, knowledge, see the door, listen to the sound, Check the details, gaps, lights and windows, chassis, engine, interior, tires and wheels, etc., these methods look nothing, when you actually will find one of the differences, I think there should be a lot of friends Has been doing it! During the period do not understand or want to know the specific content, you can give me a message! Finally, we talk about auth...

Car models are divided into 2D drawings and 3D drawings. 2D drawings: simply 2D is a linear plane diagram, there is a line to the vehicle shape, interior details, tires and other sketches out, just like the painting of the same picture, but the 2D linear chart of each line are with Data, so when drawing 3D drawings, if the import 2D map, the designer can be based on these lines of data to describe the design. Although it still takes some time, but compared to pure picture reference design, whether it is time or simulation accuracy is much higher. 3D drawings: Tong Tong model is generally used PROE software for 3D design, 3D design, also known as three-dimensional design, is a new generation of digital, virtual, intelligent design platform based. He is based on the plane and two-dimensional design on the basis of the design goal more three-dimensional, more visualized a new design method, just like a 3D movie is a meaning. When the customer can provide the 3D map to t...
