Luminus launches Pico-COB LEDs with 3.5mm or 4.5mm LES and 675lm or 1255lm output

Luminus Devices Inc of Sunnyvale, CA, USA – which designs and makes LEDs and solid-state technology (SST) light sources for global illumination markets – is expanding its Gen4 LED chip-on-board (COB) portfolio with two new Pico-COBs with high output and very small light-emitting surfaces (LES) that enable spot lights with compact form factors, narrow beam angles, and high center-beam candle power.

Small, 6mm LES COBs are typically limited to about 9° viewing angles. Luminus’ new Pico-COBs enable fixtures with viewing angles as narrow as 3-5° and produce high flux density (punch) that is important for high quality-of-light directional lighting applications such as retail, museum, residential and hospitality lighting.

The CXM-3 has an LES of 3.5mm and produces up to 675 lumens of at least 90-CRI (color rendering index) warm 3000K light, making it a suitable replacement for a 50W halogen spot. The CXM-4 has an LES of 4.5mm and generates up to 1255 lumens. As with all Luminus COBs, they are specified and 100% factory tested at a junction temperature of 85°C to ensure performance and consistency that meets the users’ expectations in real-world application conditions.

The higher maximum case temperatures and maximum drive currents of Luminus’ Pico-COBs with Gen4 technology can be leveraged to create innovative designs with smaller form factors, says Tom Jory, VP of illumination marketing. “This means lighting designers can specify luminaires with our Pico-COBs and create unique dramatic effects with longer throws and narrower beams produced by tiny fixtures incorporating sleek designs that are hidden in the architecture,” he adds.
