Toyoda Gosei Co., Ltd. based in Kiyosu, Japan reports that the company has developed its first automotive headlamp LED as a new LED product. In-house tests confirmed that these LEDs consume little energy but achieve very high luminance. The company said in a news release that it leveraged its blue LED crystal growth technology to improve the structure of gallium nitride (GaN) crystals in the new LED light source. The company also adopted flip-chip technology for good heat dissipation.
According to Toyoda Gosei, the headlamp LEDs can emit up to 2,300 lm, and bi-functional systems that produce both high and low beams from a single source can use the LEDs.
The company asserts that headlamps employing these LEDs can help decrease energy consumption in electric and fuel cell vehicles, as well as other next-generation vehicles. Furthermore, the company expects the headlight LEDs to be adopted widely in the future. Toyoda Gosei says it will continue developing a variety of headlamp LED light source types to meet customer needs.
