Bridgelux Introduces Micro SM4 LED To Address the 20-40W Replacement Lamp Market

Bridgelux Inc., a leading developer and manufacturer of LED lighting technologies and solutions, today announced an expansion of its broad portfolio of solid-state light sources to address the requirements of the $1 billion 20-40W lamp replacement market with the introduction of the Bridgelux Micro SM4. Leveraging Bridgelux’s award-winning array technology into a surface mountable LED component, the Micro SM4 delivers high flux density in a smaller footprint, making it ideal for applications where discrete LEDs are preferred.

The Bridgelux 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 20-40 watt incandescent, 20-35 watt halogen, B10-style (candelabra), and low wattage compact fluorescent lamp replacements.

Using only 4.6 watts of power, the Bridgelux Micro SM4 will deliver 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.  Production shipments of the Micro SM4 will be available in the first quarter of 2012.

“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.”

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.  As with all Bridgelux light sources, the Micro SM4 is offered with a five year warranty.

Main specifications:

Typical Flux
2700 80 370
90 330
3000 80 400
90 360
5600 70 520
