Bridgelux launches Micro SM4 LED for 20-40W replacement lamp market

LED chip and lighting array maker Bridgelux Inc of Livermore, CA, USA (which claims to be the only vertically integrated maker of LED solid-state light sources specifically for the lighting industry) has expanded its portfolio of solid-state light sources to address the requirements of the $1bn 20-40W lamp replacement market. Leveraging Bridgelux’s array technology into a surface-mountable LED component, the Micro SM4 delivers high flux density in a smaller footprint, suiting applications where discrete LEDs are preferred.

Bridgelux says that the Micro SM4 can reduce 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 (CFL) replacements.

Using only 4.6W of power, the Micro SM4 can deliver 330-520 lumens in both warm-white (2700K and 3000K) and cool-white (5600K) color temperatures. Minimum 80 and 90 CRI (color rendering index) options, with 3-step MacAdams Elipse color selections, will be offered for warm-white products. Production shipments will be available in first-quarter 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,” says VP of marketing Jason Posselt. “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,” he adds. 

Bridgelux says that the Micro SM4 features the latest technical advances in epitaxial gallium nitride (GaN) layer growth, LED chip design and packaging technologies. The 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.

Bridgelux’s products are on display in booth 1B-D22 at the Hong Kong International Lighting Fair (27-30 October).
