Toyoda Gosei develops 200lm/W surface-mount 3030-type white LED package for general lighting

Toyoda Gosei Co Ltd of Kiyosu, Aichi Prefecture, Japan has developed a new surface-mount 3030-type white LED package (measuring 3.0mm x 3.0mm x 0.65mm) for general lighting applications (such as bulbs, tubes, downlights and ceiling lights) that produces up to 200 lumens per watt (lm/W), while maintaining color fidelity. The firm says that the new package (combining two blue LED dies with phosphors) offers a cost-effective alternative to fluorescent and lower-CRI (color rendering index) LED products and can help to reduce overall energy consumption.

Toyoda Gosei says that the increase in efficiency (compared with its prior LED package) has been achieved through improvements to both die and package materials. The package combines high efficiency and low thermal resistance to enhance the performance of the LED, and uses thermos-setting plastics to provide high reliability while maintaining a superior gas barrier, says the firm.

Samples of the 200lm/W package (TG White 30 H) will start shipping available in March. Additionally, Toyoda Gosei will launch a 185lm/W package (TG White 30 E, containing one die) that is cost competitive. Mass production will start in April. Further development of an even higher-efficiency package is planned for fall 2016.
