Toyoda Gosei develops new LED package
Toyoda Gosei has developed a new surface mount LED package for lighting that produces up to 200 lumens per watt (lm/W), while maintaining colour fidelity. The LED package is designed for general lighting applications, such as bulbs, tubes, downlights, and ceiling lights.
According to the company, the new package provides a cost-effective alternative to fluorescent and lower CRI (Colour Rendering Index) LED products and can help reduce overall energy consumption.
The new surface mount component 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 says it 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.
