Electronic Development Trends Of automobile lighting system

For decades, LED is mainly used in high-end automobile lighting market. But in the coming years, it intended to compete for a larger share of the automotive market. The recent performance of the continuous improvement of the product is to speed up the decision-making process of this. Visteon global director of external parts production line, Mr. Dieter Schaper noted that, due to recent rising light-emitting diode production has doubled, so has entirely possible with the "large number of light-emitting diodes" to replace halogen headlights, which in two years ago simply impossible.

Vehicle manufacturers choose to replace the traditional light emitting diode bulbs of course there are many reasons, but what kind of automobile lighting system installed in the position is still one of the issues discussed. The inner part, the people are most concerned about is to reduce energy consumption and warranty costs. In many applications, only the traditional bulbs energy emitting diodes 1/4, in the vehicle interior under the effect of electronic hardware, automobile lighting systems saves one watts each, the energy can be applied to other places. In life, the light emitting diodes up to 10,000 hours, while the bulb is only 3 million hours, which means that the former will never burn out, and car manufacturers do not have the dealer will replace a 50 cents per bulb had to pay about $ 30 for warranty costs. "Eventually all the internal parts automobile lighting system will use light-emitting diodes," Osram Opto Semiconductors LEDs Division Marketing Director, Mr. Mike Godwin confidently predicted.

Carmakers are most valued and distinctive appearance personalized, while net color light-emitting diodes and high-tech avant-garde feel can firmly attract attention. In addition to the above factors, cool appearance, light emitting diode has more practical advantages, the lighting assembly of the parts to be smaller than conventional multi-fine (according Visteon estimated, the volume reduced by 55%), which gives designers space design greater freedom.

Although each car manufacturer is struggling to compete for more market share, but that does not mean they must choose high-tech solutions. After all, the incandescent lamp has been used for 20 years, has become a cheap and common standard products. However, due to the automobile lighting system usage has increased annually, vehicle manufacturers are also increasingly willing to performance and reduce long-term costs and make additional investments.

Mr. Godwin said: "In certain areas, light-emitting diodes and light bulbs cost curve has been close and consistent." Such as the radio in the dashboard and automobile lighting systems, light bulbs in reducing heat losses and warranty costs have been offset by light-emitting diodes the initial purchase costs. Godwin pointed out that as faster system responsiveness; vehicle manufacturers are rapidly making changes.
