Continental group launched LED lighting control unit

Light emitting diode (LED) has become an important trend in the application of new vehicles. Continental group recently launched the intelligent lighting control unit has a lot of advantages, so that the car and truck drivers at night in the LED lights more clearly observe the road ahead.

At present, light-emitting diodes have been used in car and truck headlights. The past is mainly used for daytime driving lights, lights or flashing lights and other auxiliary lighting function LED, is now increasingly used for beam lights and high beam. Different from the traditional halogen bulbs, LED lighting devices need to have a more complex electronic control system to cover all lighting functions. Continental group is a leading position in the development of such systems. The new lighting control unit is rapidly leading the reform of automotive lighting system, in order to achieve a clearer vision, improve security. The electronic control system of this new type of passenger car and commercial vehicle has been put into operation.

Make full use of the advantage of LED Technology

Light emitting diodes have a lot of advantages over light bulbs or xenon headlights. In addition to help designers to develop a unique shape of the lamp, led also has high efficiency, long life characteristics, and lower energy consumption, impact resistance, no maintenance.

However, in order to give full play to the advantages of light-emitting diodes, electronic control devices must be used. This is because unlike the traditional bulbs, LED can not directly through the vehicle power supply voltage. Therefore, the need to use electronic devices to monitor the power supply voltage. Electronic controller uses pulse width modulation to control light intensity. If the LED is used only for a signal light, such as a flash lamp, a wide light or a tail light, there is no problem. However, since the LED is also used for active steering headlights, electronic control devices must be used to handle a large number of new regulatory tasks.

To this end, the introduction of the mainland group to focus on the control of all lighting innovative lighting control devices. The first phase of the development of electronic devices can adjust the brightness of the eight lights. Each LED group can be controlled separately, according to the road conditions regulating the light, do not need other mechanical devices to transform, so it is better than before in any way, even the most sophisticated mechanical system can not achieve this effect. For the special highway or country road lighting, soft light transform, illumination curve, or expand the intersection, the group view - light regulator in less than a second time to support all the functions, which provides great flexibility for the designer and design safety engineer.

In 2011 - broad market prospects

As one of the most advanced systems in the market, the new control unit of the continental group is well received by the automobile manufacturers. Two European manufacturers decided to put into production in 2011, which provides a strong proof. Currently, other orders are under negotiation. Continental group has become a leader in the rapid development of the market. Analysts believe that not only the number of LED applications in the car is growing at an alarming rate - more than 800 mark just around the corner - but also applies to the development of the headlights before quite fast. Analysts predict that the next three years will grow at a rate of 150%.

Tran, a professor at the University of Darmstadt, Germany, director of lighting engineering Quoc Khanh pointed out: "the significant advantage of light-emitting diodes is that its service life is higher than the traditional headlights. Halogen lamp life can reach up to 1000 hours, xenon lamp can reach up to 2000 hours, while LED is more than 10000 hours. Light emitting diode is also reflected in the advantages of energy efficiency. Similarly, in the automotive lighting engineering, high output light-emitting diodes with high energy efficiency and environmental protection. This is because of its long life, high lighting efficiency - the next few years is expected to increase to 150 lumens / watt, and has good controllability. "

Tightly networked LED control electronic system

Continental group is one of the few manufacturers in the market to integrate lighting control units into the automotive data stream system. The control unit can communicate with the vehicle central control system through LIN and CAN, and can handle the received speed, steering angle, driver lighting demand and other information. In addition, the electronic unit adopts a modular structure, which can be easily adjusted for different applications of various models.

In addition to intelligent electronic functions, Continental group lighting control unit also has a lot of physical advantages. In the compact size of the pocket calculator, the control unit integrates up to four control systems, thus saving valuable space in front of the car. Unlike the same control system, the continental group's solution is not to integrate it in the shade, but as a separate component fixed outside the. In this way, when the protective cover of the head lamp is damaged, the controller can continue to be used, and the utility model is favorable for reducing the cost and the maintenance cost. On the contrary, electronic devices can be replaced without changing the headlights. What's more, this system can withstand the high temperature of the engine room. As with the engine management system, the continental group's cost optimized lighting control electronics system is very strong, almost unaffected by temperature changes. In the past, the design of LED headlights belong to the automotive manufacturers in many technical details of the dazzle, is a "flashy" electronic devices, and now the LED can work side by side with the engine.
