Toyoda Gosei has developed its first automotive headlamp LED as a new LED product. According to in-house tests, these LEDs achieve ‘world-class luminance and low energy consumption’.
Toyoda Gosei says it has applied the ‘blue LED crystal growth technology’ it developed over many years to improve the structure of gallium nitride (GaN) crystals in this new LED light source, with ‘flip-chip technology adopted for good heat dissipation’. It claims the headlamp LEDs can achieve high luminance of 2,300 lm and can be used in bi-functional systems that produce both low and high beams from a single light source.

Headlamps employing these LEDs will help reduce energy consumption in electric vehicles, fuel cell vehicles and other next-generation vehicles, and are expected to come into widespread use in the future as an environmentally-friendly product. Toyoda Gosei will continue to develop various types of headlamp LED light sources to meet customer needs.
According to just-auto’s QUBE research service, automotive lighting is undergoing a rapid technological change, with the sector expected to move rapidly from bi-xenon HID to LED, while laser technology is also now appearing on the market. Global LED front lighting volumes are forecast to more than triple to over 10m units globally by 2020.
