Daytime running lights is a special lamp, started the car engine will automatically open, day or night.  Its main role is used for road traffic in the road in case of fog or rain weather, capable of producing signals to other road users of earlier detection and better identify the vehicle.

Early most of these daytime running lights halogen bulb is used, although power consumption is not, but with advances in technology, depot are now designed using daytime running lights mostly higher brightness of the LED configuration, can significantly reduce up to 35% of electricity more can increase the battery life, and the longest life expectancy of 8,000 hours, almost equivalent to the vehicle life.

Daytime running lights for cars, many consumers will think that its main function is decorative, and in fact, this configuration of the traffic safety will also play a significant role.

It can improve the identification of the vehicle is. According to official statistics, vehicles with daytime running lights, can reduce vehicle accidents 12.4%, 26.45% and also reduces the risk of dying of a car accident.

27 EU member states unanimously adopted new regulations in the future all new EU cars and minivans produced must install daytime running lights, daytime running lights also have to improve road safety, including cars and minivans from 2011 to February 7 the date of implementation, trucks and buses in August 2012 onwards. European Commission Vice President responsible for industrial affairs, said in a statement Taya Ni, install daytime running lights can help reduce traffic accidents, while protecting the environment is also a good measure.

For the Chinese, although not yet to develop this legislation, but many car manufacturers have jointly approved and the new high-distribution models was equipped with daytime running lights. From the perspective of vehicle safety considerations, the use of daytime running lights will become a trend.

General power of 70W halogen headlamps, while the daytime running lights only 13.5W of the total power consumption, energy saving is to save money, daytime running lights as a product of the luminous flux 70-90LM, color range in the range 6000K-6700K, than conventional halogen light but also bright, power consumption is only 20% of halogen headlights. Entire light pollution, no noise, no electronic interference, the use of advanced control technology constant, uniform light, light color and full, long-lasting constant. Daytime running lights, power consumption is only 25% of normal lights to 30%, so it is safe and environmentally correct.

To our design and production of the idea stems from the EU's daytime running lights ECER87 before drafting regulations in some EU member states, many cars are equipped with daytime running lights, because the geography and climate in the EU caused by fog, rain cause weather more cars are driving in traffic with headlights, a new generation of energy-saving products on-line design inspiration off the lights settle down, and finally last year, our R & D team successfully developed daytime running lights (including many car-specific models), the product selling domestic and foreign markets. 2003 xenon lamp into the Chinese market, causing a wave xenon lamp boom, until now xenon lamp in China is still growing, daytime running lights as a new automotive safety lighting system, together with EU regulations to promote the domestic market, daytime running lights are also a good.

Car traffic on the usefulness of

Installed in the front section of the daytime running lights, daytime running is to make the vehicle easier to be recognized out of the lamp. Its effect is not to make the driver can see the road, but to let others know a car drove up. Therefore, this lamp is not lighting, but a signal lamp. Of course, the installation of daytime running lights make car look cool, shiny metal, but the maximum daytime running lights effect, is not beautiful, but to provide identification of the vehicle is. Headlights on driving in foreign countries, can reduce vehicle accidents 12.4%, 26.4% and also reduce the accident risk of dying. In short, daytime running lights purpose is to traffic safety.

Thus, in recent years many countries have developed the relevant standard daytime running lights installed to ensure the production of daytime running lights can really play to protect the safety of efficacy. Which was undoubtedly the most representative of the Economic Commission for Europe ECE automotive technical regulations in ECER79. China is also on January 1, 2010 came into effect March 6, 2009 issued by the national standard "car equipped with daytime running lights light performance." Our standard is based on ECE R79 This fourth edition revised version of the blueprint drafted by the deletion of ECE R79 standard in the management of the chapter and annex
1) Specifications:
The main technical requirements are consistent with the ECE R79.
Here, we take a look at the DRL a qualified product, exactly where is not free to change.
First, the standard clearly states, daytime running lights must be white light color,
Color characteristics must meet specified requirements.
White chromaticity coordinates:
Blue boundary: x ≥ 0.310
Yellow boundary: x ≤ 0.500
Green Border: y ≤ 0.150 +0.640 x
y ≤ 0.440x
Purple border: y ≥ 0.050 +0.750 x
Red Border: y ≥ 0.382
Second, the required light-emitting surface area of ​​not less than 40cm2.
The most important point is that with the optical performance, daytime running lights brightness to meet the basic requirements, but not too bright, so as not to interfere with others. Is reflected in the technical parameters of the reference axis of the luminous intensity of not less than 400cd; other direction of the luminous intensity of not less than 400cd and with the light distribution of a percentage point in the figure corresponds to the product; in any direction, lighting the light intensity should not exceed 800cd.

Photometric distribution map
2) Life: 5000H
3) high and low temperature: -40 degrees to 80 degrees
4) Light color temperature: 6000K

Europe 2011 to enforce motor vehicle daytime running lights, LED will be more widely used in automobiles.
