Questions about automotive lighting LED lights 1
Mercedes-Benz designer Stefan Handt has said that car lighting is like cufflinks on an evening dress, adding to the icing on the cake. I think the pure white LED light is like the veil worn by the bride, which is not only noble and holy but also safe.
Five questions about Daytime running lights & Fog lights
1. What light to turn on in broad daylight, That's showing off！
Daytime running lights are not a light or away for a driver to see the road clearly. It is in order to let other people know that your car is about to drive over, which is part of the signal lights. In northern European and North American countries such as Sweden and Canada, because of the long winter and frequent snow, transportation authorities require daytime driving with lights on. But, you might say, China is not northern Europe. Is it necessary to have the sun all day in some regions? It is still necessary because human eyes are sensitive to bright things, if you let others find you in the first place when you driving, it can greatly reduce the chances of traffic accidents.
2. The light stays on. Isn't that a waste of energy and electricity?
Take the two-in-one product of LED daytime running lights and fog lights installed by New Fox, It has six LEDs on each side, 1 watt each, and the total of both sides is only 12 watts. Counting three LED fog lights on each side, the total is 30 watts. Even LED headlights are more energy-efficient than halogen headlights. Single halogen headlights are available in 55W, 75W, and 100W specifications, 75 watts, and 100 watts, while LED headlights are generally controlled within 40-80 watts. In addition, the wattage of HID start-up instantaneous current is higher, with single lights rushing to more than 90 watts. Thus, there is no reason to doubt that LEDs cost electricity.
3. Hey bro, Your lights are on!
This raises the question of how to use LED daytime running lights. Take above-LED products as an example. When the car engine starts, the daytime running lights will automatically turn on. If no light is turned on, the daytime running lights should have full power output to serve as a safety warning. Turn on the small light daytime running lights will be half-light, this is because the width of the light has a warning role; Turn on the headlights and the daytime running lights go out because the headlights are brighter and there is no need to turn on the daytime running lights. This is consistent with the use order of the daytime running lights on Mercedes and BMW, but many of the inferior daytime running lights will light up to the end, but not half-light.
4. It makes my eyes dazzled. What a nuisance!
In fact, good LED daytime running lights products are less likely to make other drivers uncomfortable if you are driving normally on the road, because the daytime running lights also have a certain angled, thanks to the role of the reflector. Only when you get close to the front of the vehicle can you feel a bit dazzling, which will not affect the vehicles and pedestrians on both sides of the road. The daytime running lights should meet the basic brightness requirements, but not too bright, so as not to interfere with others, some businesses only pursue brightness, ignoring the Angle, resulting in light pollution.
5. Why is that man's fog light is white?
China has a large dimension, and complexity of its climate and environment determines whether to use yellow light or white light. Studies have shown that the human eye's sensitivity to yellow light is 20 times that of red or blue light, which is also an important reason why most fog lights and street lights use yellow light. Yellow lights are mandatory on North American models, especially snowplows in the north Of the United States, because white light is useless when it snows. However, there is no provision for the use of yellow light or white light in new domestic cars, generally use yellow light, refit with white light is not necessary to use, It can be decided according to personal preferences and local climate conditions.
