Bridgelux Innovation Brings Micro SM4 LED Light Source to Market
The Bridgelux Micro SM4, a multiple die emitter, dramatically reduces the component count, cost, complexity and size of diffuse or directional lamps, the popular ceiling fixtures seen in modern office buildings and retail establishments. The new product leverages design and manufacturing advances at Bridgelux and expands the company's broad portfolio of solid-state lighting solutions.
The Micro SM4 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 watts, but it emits as much light as a 20-40 watt incandescent or 20-35 watt 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.
The new smaller footprint, surface mountable emitter requires fewer components for applications typically using discrete LEDs. The 20-40 watt replacement market segment constitutes a $1 billion opportunity in the $100 billion market for lighting.
Using only 4.2 watts of power, the Bridgelux Micro SM4 component will deliver between 330 and 500 lumens in both warm white (2700K and 3000K) and cool white (5600K) color temperatures. Minimum 80 and 90 CRI options, with 3-step MacAdam Ellipse color 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.
