Press Release












China’s Leedarson Blazes Trail in LED Lighting with Stylish, White Heat Sinks Using LNP* Konduit* Compound from SABIC Innovative Plastics Pittsfield, MA—March 3, 2011—SABIC Innovative Plastics today announced that Leedarson Lighting—a leading endto-end private label lighting manufacturer and provider of energy saving lighting solutions—has selected LNP* Konduit* thermally conductive compound in a new white formulation to manufacture heat sinks for two of its light-emitting diode (LED) retrofit bulbs. Headquartered in Xiamen, China, Leedarson is using the new LNP Konduit compound material as a replacement for aluminum in these heat sinks to achieve key goals: stylish and heat-stable white color without the need for secondary painting; higher productivity through the use of injection molding; and compliance with industry requirements for electrical isolation. By combining superior aesthetics and production advantages with outstanding heat dissipation performance, LNP Konduit compound can help drive adoption of LED lighting and expand its benefits of energy savings and reduced environmental impact. “As the first lighting manufacturer to use white LNP Konduit compound for heat sinks, we are leading the industry by offering high-efficiency, stylish LED retrofit products to consumers,” said Eder Lee, general manager, Leedarson Lighting. “We believe improved appearance of LED bulbs will have a significant effect on market acceptance. As demand increases, LNP Konduit compound will make it easy for us to boost production capacity because injection molding is highly scalable compared to metalworking. This versatile material also provides the freedom to design the next generation of heat sinks for future LED technologies.” “With life spans of up to 50,000 hours and very low power consumption, LED lights hold tremendous potential for energy conservation,” said Peter Chan, president, Greater China, SABIC Innovative Plastics. “As part of our commitment to sustainability solutions, SABIC Innovative Plastics offers a portfolio of specialty materials that can enhance LED design and manufacturing. In particular, our LNP Konduit compounds for heat sinks can play a crucial role in optimizing brightness performance and long useful life of LEDs. Our pioneering work with Leedarson Lighting is an important milestone in achieving these environmental goals.”

Replacing Aluminum with LNP Konduit Compounds
Leedarson created cylindrical heat sinks for its 2-W clear candle-shaped LED bulb and its 2-W clear, round LED bulb using the new white LNP Konduit compound. These bulbs are sold in major home improvement stores and worldwide chain stores. Leedarson evaluated other conductive thermoplastics and chose LNP Konduit compound for its superior conductive performance, nonhalogenated flame retardance, electrical isolation properties to pass the 6-kV breakdown test, and stable color performance. Compared with aluminum and other metals, thermally conductive compounds typically have lower coefficients of thermal expansion (CTE) that help reduce stresses from differential expansion. They also weigh significantly less than aluminum. LNP Konduit compounds offer tremendous flexibility to designers, who benefit from the freedom to create complex shapes and achieve part integration using injection molding instead of traditional stamping, casting, and secondary finishing required by metals. Thermoplastics open the door to innovative configurations that can optimize heat transfer—all while providing the cost benefits of high-volume production.

Introducing 30% Smaller Power Inductors for High Frequency Application
The Alpha-Core Division of Bridgeport Magnetics Group Inc. introduces a line of high power inductors for high frequency applications with a minimum 30% size and weight reduction using high performance gapped amorphous ribbon cores instead of conventional cores of silicon steel or powdered iron. Alpha-Core’s new amorphous core power inductors combine high inductance and current levels with low losses at frequencies in the 20 KHz range. High wattage switching mode power supplies benefit from the compact design and much reduced weight. Other applications include power factor correction and harmonics filtering in UPS systems, variable frequency inverters and on-grid solar and wind power systems. Alpha-Core power inductors are box shaped and fully encapsulated in black epoxy resin. The insulation system is class F (155C). The two leads exit from the short end. Initially AlphaCore offers inductance values ranging from 100 uH to 5,000 uH and RMS current ratings up to 60A. Prices start at $25.00.
