Most of the fire engines we meet on weekdays are red. According to the survey, fire engines in most countries are red. Because it is the most eye-catching, it can be seen from afar.
So do you think about it? Why are fire equipment and markings red? Some people may say that they use the color of fire to symbolize 100,000 fires. This is only a bit right. Experts have found that red can stimulate appetite and people can eat at ease. Red fire signs are placed on flammable key parts to ease people's turmoil and reduce fire accidents. Therefore, the use of red fire engines, for those who are panicked in the fireworks, can play a stabilizing role.
In addition, we share with you: The sunlight consists of seven colors: red, orange, yellow, green, cyan, blue and purple. Their wavelengths and deflection angles are different. When sunlight strikes an object, various objects have different absorption and reflection capabilities for different wavelengths of light, forming various colors. In short, if an object can reflect one or more lights in the sun and absorb the rest of the light, the object will appear as a reflected monochromatic or polychromatic light. In the visible light, the red light has the longest light wave, and the deflection angle is the smallest, and it easily penetrates the water layer, raindrops, dust, and fog. Orange and yellow light are not afraid of obstruction and can penetrate the above objects. Therefore, the fire engine is painted red in order to allow people to see it from far away in dusty weather, dusty environments, or stormy weather, to make way for it so that it can complete the task of extinguishing fires as soon as possible.
Fiber Laser Marking Machine is a new generation of laser marking system developed by our company using the advanced laser technology. This laser engraving machine uses the fiber laser to output laser, and then the marking function is realized by the high-speed scanning galvanometer system. The optical conversion efficiency of fiber laser marking is high, reaching more than 30%. Metal Laser Engraving Machines is air cooling, the whole machine is small in size, the output beam quality is good, and the reliability is high.
The structure of it is simplified, easy to control.
The optical system adopts a fully sealed structure with a red light preview function, which has a more beautiful appearance and more convenient operation;
High photoelectric conversion efficiency, high beam quality, fine lines and small spots;
It adopts air-cooling method for cooling, which has low energy consumption.
