Toyoda Gosei develops automotive headlamp LEDs

Toyoda Gosei Co Ltd of Kiyosu, Aichi Prefecture, Japan has developed its first automotive headlamp LED as a new product. According to in-house tests, the LEDs achieve what is claimed to be world-class luminance with low energy consumption.

Toyoda Gosei has applied the blue LED crystal growth technology that it developed over many years to improve the structure of gallium nitride (GaN) crystals in the new LED light source, with flip-chip technology adopted for good heat dissipation. The headlamp LEDs can achieve high luminance of 2300lm and can be used in bi-functional systems that produce both low and high beams from a single light source.

Toyoda Gosei says that headlamps employing such LEDs can help to 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 aims to continue to develop various types of headlamp LED light sources to meet demand.
