LED4Auto 06: LED and HB-LED for automotive applications

Quick Facts

Date of Release: Publisher: Number of Pages:

July 2006 Yole Développement 150+ slides (PowerPoint presentation)

Objective:

High Brightness LEDs (HB-LEDs) are being actively pursued for use in automotive exterior lights as well as headlamps.  In addition, HB-LEDs are in contention to replace conventional lamps and lower brightness LEDs on the interior of the car too.  To address these trends, Yole Développement has released a new report describing the market and technology trends for HB-LEDs in automotive applications and lighting.

Summary of Findings:

The report finds that HB-LEDs for exterior front lighting will gain an increasing market share over “conventional” LEDs for the car’s interior.  Driving this trend will be the accomplishment of a major milestone in 2007: GaN-based LEDs will reach a higher luminous efficiency than fluorescent lighting.  This event will begin the ramping up of the solid-state lighting business in 2007, particularly for interior and exterior automotive lighting applications.

There are strong growth opportunities for HB-LEDs in automotive applications.  HB-LEDs offer many benefits, including:
Increased reliability (e.g. lifetime much larger than needed)

• Use for both interior and exterior lighting
• Low-power consumption and increased and power saving
• Mercury free products

The LEDs small size also enables:

• New design possibilities and high tech appearance
• Increased integration

Moreover, in terms of safety, LEDs have a faster reaction time.  LEDs light up approximately 250 milliseconds quicker than bulbs.  At 100km/h speed, LED brake lights appear 7 meters sooner.

Large market opportunities also exist for HB-LEDs for exterior front lighting in cars.  As the HB-LEDs performance increases, fewer chips will be necessary (less than 15 should be necessary in 2009 for all functions).

The cost objective for auto ($10/kilo-lumen) will be reached in 2010 for a wide range of HB-LEDs in exterior front lighting.  However, HB-LEDs are expected to be available in high-end autos in 2007.  Today a high-end car can have up to 200 LEDs and this figure is expected to grow in the future: it could be up to 800 LEDs in 2009. The market for HB-LEDs for exterior front lighting is relatively new.

We forecast that the market for automotive exterior lighting will be 40% of the total HB-LED automotive market in 2009.

The white LEDs market will be shared by 5 major players: Lumileds, Osram, Nichia, Toyoda Gosei and Cree.

Moreover, the recent interest for HUDs (Head-Up Displays) in cars should also benefit from the HB-LEDs technology. HB-LEDs are currently bright enough to be used as a backlight on an LCD, instead of CCFL, which should help to move more LCDs into automobiles too.  The favored applications here are center console displays and entertainment systems
