In today's increasingly flew into the modern automotive technology, car ownership has soared. Corresponding driving at night has also become a regular job. Corresponding common sense is the owner of the car also gradually increased. Xiao Bian gave you today to talk about the lights in our technology and adapt to the automotive technology.
First, the composition of headlamps and lights way
Headlamp is to convert light energy to invest in roads and electrical appliances. By the light bulb single headlights, focus the light rays toward the road and mirrors, produces a reasonable distribution of light composed of refractive lens. Set the front of the vehicle has two or four headlamps, fog lights and some do also added 2 rain, snow, fog, road lighting. In addition to the front headlights do enough to ensure a clear distance lighting, but also has anti-glare properties, in some cases also used for temporary lighting headlamps, made light of distant signals, such as overtaking give way signal. Headlamp with incandescent light source, making simple, convenient control, instantaneous good, reliable and easy exchange of batteries for low voltage DC power supply, power tungsten filament heated to 2800 ~ 3000K, hot filament radiates light to the surrounding space .
Tungsten are sealed in opaque glass bulb, the bulb is filled with argon and nitrogen mixed gas halogen element, to prevent the tungsten at a high temperature oxidation and sublimation. Headlamp illumination lights from the optical design is based, according to distance away, electric power, manufacture of high precision, on the contrary, according to from the past, driving poor security. Safe minimum distance, including the driver finding the target response time, response time operating mechanism works in these two vehicles within the distance according to the original speed, braking distance and continue to travel the distance necessary security clearance. Obviously, the higher the speed, the greater the safety distance. Therefore have to increase the light from the lamp. Traffic law as the speed is less than 30km / h the vehicle according to distance 30M, car far away from the light 100M, many pedestrians in the vehicle section of the car will use the beam for lighting, according to distance of 50M.
Second, the headlamp's optical properties
Design lights to fully consider the person's vision and road conditions, the impact on human vision. Light and dark eyes and a keen ability to distinguish colors. Lights at night is the thing that catches the eye cast on the target of the reflected light, the human eye visible wavelength of 380 ~ 760NM. Main color is yellow incandescent light, yellow light on the road through the air with dust, good performance. Rain and fog mosquitoes and other material in the larger formation of small bright light, so that bad air into the diffuse light barrier. So the election is the fog lights and more powerful through the yellow light microscope. In addition there are a variety of automotive headlights light lights outside, the choice of lenses of different colors into the needs of incandescent light color. Is based on three primary colors of light and color coordinates determined by the wavelength. Signal in the power supply voltage and ambient temperature fluctuations, the light color will still be stable, it will not cause signal confusion. Lights have good optical quality in order to ensure safe driving.
Third, the headlamps feature
Many drivers have had such a feeling. When the head of the driver, pedestrian street lights light stimulation will be produced as a short black, also known as blinding. Prevent the reasonable use of blinding lights first. Car range will be more roads or vehicles and pedestrians near light with lighting. Another way to prevent the blinding lights of the past with a good light. Presented in the light and dark areas near lighting a reasonable graphics. The light pattern of selected, well just symmetrical, the light cast in the appropriate length and width of the road constitutes a band of light. Running time with successive scans the road to find obstacles. The beam is asymmetric, bright and also slightly wider in front of the right to recognize the right of the logo in the left narrow dark to prevent car drivers will dazzle. At this point, many domestic automobile manufacturers or by the traditional halogen lighting as a headlamp.
Fourth, the excellent modern features of xenon lamp
Now comes the headlamp features, it now had to refer to the gradual popularization of the characteristics of Xenon lamp. Compared with traditional halogen lamps, xenon lamps (HID) with the above-mentioned number of essential advantages. The first is the high brightness output. Same power halogen HID lamp brightness is about 2 to 3 times, and range farther, wider, and thus effectively improve traffic safety at night. Xenon lamp color temperature and sunlight are similar, but with more green and blue components, which appear as blue-white shade. This substantial increase in the shade of blue and white road signs and signs of brightness. Followed by the high brightness of comfort.
Xenon lamps can produce 4000 ~ 6000K color temperature of light, its brightness 3 times higher than the efficiency of halogen, to enhance the night and fog clarity of sight when driving had a significant effect, can effectively reduce night driving eyestrain. Third, long service life. Xenon lamp works determines that it is not common in traditional tungsten halogen lamp issue blown scrapped its life of up to 2000 ~ 3000H, a halogen bulb about 10 times, almost equivalent to the average life cycle of car all running time. Fourth, low energy consumption. The power of traditional halogen 65W, HID lamps only for the 35W, as it can significantly reduce the burden of the vehicle power system. Now in the world, specializing in research and development and production of HID manufacturers focused on the famous PILIP, CIBIE, IPF and some other big companies.
