Luminus expands range of Gen 2 CCT tunable COBs
Luminus Devices Inc of Sunnyvale, CA, USA – which designs and makes LEDs and solid-state technology (SST) light sources for illumination markets – has expanded its Gen 2 CCT tunable chip-on-board (COB) LED portfolio with the introduction of the CTM-18 and CTM-22. Both feature the same 6500K to 2700K color combination of the exiting CTM-6, CTM-9 and CTM-14, along with two additional CCT (correlated color temperature) ranges: 4000K to 1800K and high-melanopic 5000K Salud to 2200K. The Gen 2 CCT tunable COBs are now available in three CCT ranges and five sizes, with the light-emitting surface (LES) diameters of 6mm, 9mm, 14mm, 18mm and 22mm. Each provides what is claimed to be industry-leading efficacy (lumens/Watt) and flux density, enabling customers to drive at higher currents to enable longer throws and more ‘punch’ in their spotlights.
The Gen 2 COBs boast two independent channels, offering warm and cool white with over 90 CRI (color-rendering index). Engineered with a multi-stripe design, they ensure what is claimed to be excellent color mixing and high flux density, suitable for directional lighting applications. With the ability to achieve system beam angles ranging from 10° to 40° using standard secondary optics, customers can enjoy uniform color output and exceptional light quality, the firm adds. The three available CCT range options, coupled with consistent white light <3SDCM (standard deviation of color matching), make the COBs suitable for a range of applications, including commercial, residential, offices, human-centric lighting, museums, healthcare, retail stores, hospitality venues, and circadian lighting setups.
A wide array of optics, holders and connectors is compatible with the industry-standard footprints commonly used for two-channel COBs.
“The industry-leading efficacy and flux density of these Gen 2 products are meeting the growing demand for tunable CCTs to provide healthy lighting environments with adaptable tones,” says David Davito, senior director of global product marketing, Illumination. “The quality of light is equally impressive, as these COBs enable the creation of narrow beams with smoother color mixing, providing a seamless dynamic directional lighting solution.”
