LED headlights domineering side leakage ten "answer fluently"

Mercedes Benz designer Stefan Handt said that the car is like lighting tuxedo cufflinks, play the role of icing on the cake. I want to LED light like a bride wore white veil, not only noble and pure, more important is the safety.

LED, the next car lighting trend

Since the beginning of the last century in 90s to the present, LED lights have begun to have the tendency to replace xenon lamps, becoming a new technology for high-end automotive lighting. Because the LED technology uses less energy than traditional halogen lamp life is longer, is valuable to semiconductor principle of luminescent LED can let the lights smaller, so as to provide more design flexibility for vehicle.

At the 2003 North American International Auto Show, Volkswagen launched the Audi PikesPeakquattro concept car, it will be designed to narrow the front fog lamp, and for the first time equipped with a LED lamp, which is regarded as the earliest form of daytime driving lights. In recent years, whether it is a joint venture is an independent brand, low-end or luxury brands, daytime driving lights have become a standard car. From the beginning of the European countries to explore and respond to the rules of the light of the day, the use of daytime lights do improve road safety, reduce traffic accidents have played a positive and effective role. For China's automobile production and marketing power, driving safety is the primary problem. Daytime driving lights are no longer a face of the high-end configuration, and truly become a necessary vehicle to improve safety.

LED headlights in front mounted is more colorful, but also more intelligent. Such as the Mercedes Benz 2015 CLS is equipped with multi beam LED headlamps, the technology uses multiple LED light-emitting unit, which can achieve high precision distance headlamp lighting, so as to avoid the interference caused by the car driver. That is to say, even open the headlights and the other car, do not have to worry about security issues caused by. LED headlight is the fastest application of Audi, basically the whole system to replace the trend, Audi is known as matrix LED headlamps. Lexus NX LED is not only the headlights, fog lamps with LED technology. Although LED headlights are mainly used in high-end models, the feeling will be out of reach, but recently there are many car manufacturers began to try to LED headlights down to the middle and advanced models, such as the modern IX35.

Although the ability of the owners are willing to use LED lighting equipment to improve driving safety. However, the LED market is not peace, the price varies, uneven quality, good price good quality we want, but it is difficult to have such a thing on the market.

Comparison of advantages and disadvantages of three kinds of mainstream lighting

Halogen lamp is like a pot of wine, from 1960 for lamp halogen lamp born to now gone through more than half a century, yet it can be used in the long-term life and growth in nature, automobile has its need to survive, the biggest advantage is that a large number of lamps in automotive applications, so that it has the extremely cheap. The disadvantage is that the light output efficiency is low and the irradiation distance is short.

HID lamp used in automobiles in the early last century in 90s, the German car manufacturer to promote this technology, its superiority is high light output efficiency than halogen lamp, halogen lamp lumens is 3 times the life of 3000 hours, the output of easy identification of the white, blue and purple light. The disadvantage is that the first boot takes 5-7 seconds to achieve all-optical output.

Like the HID, the LED lamp has no filament, the required power is small, and it is resistant to vibration. LED light close to natural light, light output efficiency is also the other two kinds of light source can not be compared, a 1000 Watt halogen light efficiency and the equivalent of 200 Watts LED lamp, the service life of up to 30000 hours, is HID times. The disadvantage is that the market is not mature.

About car lighting color temperature

Color temperature to the absolute temperature K, the color temperature of about 3000K, light yellow. When the temperature is above 5000K, the color is blue. According to the different environment of different colors such as headlights, you want to deal with the rain and fog on the selection of strong penetrating ability of the yellow light, you will also love beautiful personality high color temperature light available. You should also know that color temperature is a measure of color temperature, not a measure of the brightness of the lamp. Halogen lamp color temperature can be from 2300K to 7000K; HID, LED lamp color temperature from 4200K to more than 8000K; the higher the temperature of the lamp, the worse the penetration of fog and rain.

In the light of LED

The 1 day open lamp showing what ah!

Day light is not a light, nor is it possible to enable the driver to see the road, but to let others know that your car is coming, is the scope of the signal, which is a bit active safety taste. In northern Europe and North American countries, such as Sweden and Canada, because the winter is longer, and often snow, so the traffic department, the daytime driving lights must be turned on. But perhaps you will say that China is not the Nordic, like some areas of the sun so big is necessary? It is necessary, because the human eye is more sensitive to light things, when you meet, if the first time to let others find you, can greatly reduce the probability of traffic accident.

2, the lamp has been bright, this is not a waste of energy consumption?

In the new Fawkes installation of the LED lamp and the fog lamp combo products, it is each side of six LED, a 1 watt, on both sides also add up to only 12 watts, is on both sides of the three LED lights, total is 30 watts. Even LED than halogen headlights, halogen lamp single lamp has 55 watts, 75 WATTS, 100 watts of specifications, and multi LED headlight control in 40-80 varnay. In addition, the number of Watts generated by the instantaneous current of HID will be higher, the light will be
