Toyoda Gosei Develops High Efficiency LED for Lighting

Toyoda Gosei has developed a new LED package for lighting that produces up to 200 lumens per watt (lm/W), while maintaining color fidelity. The LED package is designed for general lighting applications, such as bulbs, tubes, downlights, and ceiling lights. This new package gives our clients cost-effective alternatives to fluorescent and lower CRI (Color rendering index) LED products and can help reduce overall energy consumption.

The new package is a surface mount LED component that combines blue LED die with phosphors. Toyoda Gosei achieved this increase in efficiency, as compared to its prior LED package, through improvements to both die and package materials. The package combines high efficiency, low thermal resistance to enhance the performance of the LED, and uses thermosetting plastics to provide high reliability while maintaining a superior gas barrier.

Samples of the 200 lm/W package will be available in March. Additionally, Toyoda Gosei will release a 185 lm/W package that is cost competitive. Further development of an even higher efficiency package is planned for the fall of 2016.
