Bridgelux Inc. has introduced the Micro SM4, which is an expansion of the company's solid state light sources portfolio that will address the demands of the $1 billion 20-40W lamp replacement market. Capable of delivering high flux density in a smaller footprint, the Micro SM4 is ideal for applications where discrete LEDs are preferred, Bridgelux said.

The Micro SM4 dramatically reduces the component count, cost, complexity and size of the lighting system, enabling a cost-effective, high performance LED solution for diffuse and directional lighting, such as 20-40W incandescent, 20-35W halogen, B10-style (candelabra), and low wattage compact fluorescent lamp replacements.

Using only 4.6W of power, the device delivers between 330 and 520 lumens in both warm white (2700K and 3000K) and cool white (5600K) color temperatures. Minimum 80 and 90 CRI options, with 3-step MacAdams Elipse color selections, will be offered for warm white products.

"The Bridgelux Micro SM4 delivers comparable efficacy and performance to some of our smaller form factor arrays in the size of a miniaturized discrete component," said Jason Posselt, vice president of marketing at Bridgelux. "The ability to use high volume surface mount assembly methods will open up new design integration options and help our customers to improve both cost-to-market and time-to-market," Posselt added.

The new Micro SM4 features the latest technical advancements in epitaxial GaN layer growth, LED chip design and packaging technologies. These products are configured to align with industry standard drive currents to simplify the electronic driver selection process for new lamp and luminaire product development, and are offered in both 6V and 12V design configurations to enable driver design flexibility.

Production shipments of the Micro SM4 will be available in the first quarter of 2012. Just like other Bridgelux light sources, the device is offered with a five-year warranty.
