The data shows that 82% of traffic accidents occur in poor lighting conditions such as nighttime and bad weather. Automotive lighting has been listed as the first element of vehicle driving safety, which can play an active role in preventing driving safety. Choosing a high-quality automotive lighting system will effectively prevent accidents and double the safety of driving.
Studies have shown that people of different ages have different needs for light. The 60-year-old needs more than five times as much light as when they were 20 years old. As we grow older, we will have more demand for light. Therefore, in order to make driving safer at night, we need a car bulb that is far away and wide.
Quality is also one of the key elements in choosing a car. Safety and comfort come from quality products that are trusted. As an important component of the vehicle, high quality lights help prevent accidents.
According to the technical structure and application requirements of the bulb, each product has a rated life. Lifespan is one of the most important perceived factors of a light bulb. But the concept of longevity is not absolute, and of course there are no long-light bulbs. For car manufacturers and car owners, the longer the lamp life, the better, because it can reduce the replacement frequency and save costs. Based on the tungsten halogen cycle principle, the life of halogen lamps is much higher than that of incandescent bulbs. That is, when the tungsten wire is heated, the tungsten atom is evaporated and combined with halogen to form a heavier large-grained tungsten halogen compound, so that the evaporated tungsten returns to the surface of the filament, thereby delaying the service life compared with the incandescent lamp; compared with halogen and incandescent bulbs. The filamentless design allows the xenon lamp to have a longer life span of up to 2,500 hours, almost the same as the life of the vehicle.
In fact, if a bulb has a calibration life of 400 hours, that is, by design, most of these bulbs will be damaged after 400 hours of use. However, it cannot be ruled out that there are individual exceptions that will fail early. Usually, the bulb is damaged because it is evaporated during the use of tungsten and tungsten atoms are deposited on the glass envelope. There are two reasons for this damage:
1 filament breakage: During the use of the bulb, as the tungsten atom evaporates, the toughness structure of the filament is broken. The degree of evaporation can be judged by observing the tungsten deposition on the filament wound in the halogen bulb.
2. Blackening: The tungsten atom of the incandescent bulb is deposited on the glass bulb, causing the bulb to blacken.
Therefore, when purchasing the lamp, you should try to choose a high-quality product made of high-strength filament to effectively reduce the damage of the filament and extend the service life of the lamp. At the same time, the ultraviolet light emitted by the ordinary automobile bulb will cause the lamp to be damaged and yellow, and the anti-ultraviolet quartz glass bulb can effectively prevent the lamp from being blackened and make the lamp lasting as new.
Brightness and color are different concepts. Brightness is expressed in lumens. The color temperature determines the color of the light. Generally, the color temperature of the original matching lamp is about 3200K, which is yellow. In this light color, the driver is easy to relax his vigilance and affect driving safety. However, the yellow penetrating power is strong, especially in rainy days, and it can be irradiated farther. High color temperature, such as 4000K, is white in color, which makes it easy to focus and provide a more comfortable driving experience. However, if the color temperature is too high, if it exceeds 6000K, the penetration of light will decrease, which is not conducive to driving in rainy and foggy weather.
A good light shape not only provides better lighting for the driver, but also reduces the glare effect on the opposite driver. The positioning of the bicycle bulb filament is an important factor affecting the shape of the light. Many drivers will find that when driving time increases, it seems that the night car lights are getting darker and darker. This is mainly because it also has a light decay phenomenon, and the brightness of the bulb gradually decreases with the use of the lamp. This process is often slow, and if you don't pay attention, it often has serious consequences.
