LED technologies address automotive applications

EBV Elektronik has put together a new service package offering automotive lighting solutions using LED technologies.

EBV Elektronik has put together a new service package offering automotive lighting solutions using LED technologies.

This package combines LED solutions from various semiconductor manufacturers together with comprehensive application knowhow and design support.

"With our partners from the semiconductor field, we offer customer-specific solutions dealing with every aspect of LED technology, and provide an advisory service to customers during product development", says Frank-Steffen Russ, Automotive Sales Manager Central Europe at EBV Elektronik.

"Apart from providing the correct device, this means that we can also supply IC solutions that provide precision switching of LEDs".

All products and services involved in every aspect of LED technology are incorporated in EBV Eletronik's new automotive lighting solutions service package.

EBV offers a broad spectrum of LED technologies and devices from various semiconductor suppliers such as Agilent, Osram, Fairchild, Intersil, Toshiba and Vishay.

In addition, there is comprehensive optical and electrical solution support, including close co-operation with the manufacturers' application labs.

In terms of electrical questions about LED driver solutions, which now go beyond simple series resistance, EBV supports its customers in determining the best technologies and costs for specific applications.

As examples, EBV has found optimum solutions for companies such as ON Semiconductor and National Semiconductor.

One interesting field within LED applications is colour control loops.

For example, the exact colour of RGB LEDs is determined using Agilent colour sensors, and using this colour, other LED lights can be controlled and adjusted accordingly.

Colour control loops can be used, for example, for interior lighting in vehicles, as this enables the co-ordination of different lights on ceilings, fittings or on the seats.

It is also possible to adjust the back lighting for different displays using colour control loops.

The long-term stability of OLEDs (organic light emitting diodes) in display technology is also at an acceptable level for many applications.

In this context, EBV, together with Osram, offers appropriate system solutions.

With automotive lighting solutions, EBV also offers an efficient and economical LED system for electronic lighting in small quantities.

LED technology is of particular interest because of its small sise and high energy efficiency.

Above all, it is the long service life and higher changeover speed which advances the use of LED technology in the automotive industry.

Whereas incandescent lamps only light up 200ms after switching, LEDs react to the flow of current at least 1000 times faster.

This is why red LED lamps have been used for some time in CHMSLs (centre high mount stop lights).

In addition to CHMSLs, LED technology is an effective solution for other automobile applications, such as in switch rear lights, display lighting or side marker lights for trucks and cars.
