Bridgelux's new micro LED for commercial lighting

A smaller footprint on the 20 - 40 W replacement market segment constitutes a $1 billion opportunity in the $100 billion market for lighting

Bridgelux is making its new Micro SM4 surface mountable LED component commercially available.

The LED innovator says this multiple die emitter will decrease the cost and improve the performance of lighting in commercial buildings.

The Micro SM4 is aimed at dramatically reducing the component count, cost, complexity and size of diffuse or directional lamps used in ceiling fixtures in modern office buildings and retail establishments.

This LED is a light source, analogous to the heated gases or hot wires found in fluorescent bulbs and incandescent lights. The difference comes in energy consumption, longevity and control. The Micro SM4 light source consumes only 4.2 W, but it emits as much light as a 20 - 40 W incandescent or 20-35 W halogen B10-style bulb and will last thousands of hours longer.

The Micro SM4 component also delivers high flux density in a smaller footprint, giving designers, architects and lamp manufacturers greater freedom when it comes to creating and illuminating interior spaces.

“We’ve developed products with Bridgelux LED arrays over the last couple of years,” says Raimund Koehler, general manager at MeLiTec. “So we were very interested when Bridgelux told us about their new Micro SM4 light source. The smaller form factor delivering high quality light and excellent colour over angle performance gave us the edge for our new directional lamp applications. The continuing innovation that we see from Bridgelux is driving LED light source technology in the directions MeLiTec needs to cost-effectively develop the next generation of high quality, energy efficient retrofit lamps required for market conversion to solid state lighting.”

The new smaller footprint, surface mountable emitter requires fewer components for applications typically using discrete LEDs. The 20 - 40 W replacement market segment constitutes a $1 billion opportunity in the $100 billion market for lighting.

Using 4.2 W of power, the Bridgelux Micro SM4 component will deliver between 330 and 500 lumens in both warm white (2700 K and 3000 K) and cool white (5600 K) colour temperatures.

Minimum 80 and 90 CRI options, with 3-step MacAdam Ellipse colour selections, will be offered for warm white products. The new Micro SM4 light source features the latest technical advancements in epitaxial GaN layer growth, LED chip design and automated packaging technologies.

Bridgelux will be showcasing its latest products at the Light+Building conference in Frankfurt, Germany from April 15-20, in Hall 4.2 at stand J31.
