Bridgelux launches F90 Series LEDs for commercial lighting
Bridgelux Inc of Fremont, CA, USA (a vertically integrated manufacturer of solid-state light sources for lighting applications) has announced the commercial release of its F90 Series LED products for commercial lighting, which deliver a minimum color rendering index (CRI) of 90 combined with what is claimed to be industry-leading efficacy. F90 LED products use potassium fluorosilicate (PFS) phosphor technology licensed from Current Lighting Solutions LLC for use in commercial lighting applications.
For traditional LED technology, higher CRI results in a lower efficacy. By replacing broadband red nitride phosphor with narrowband red PFS phosphor, the F90 LED products can achieve today’s CRI80 LED efficacy with a CRI of 90, says Bridgelux. Lighting customers can simply replace their existing LEDs in their lighting products with the new F90 LEDs for CRI90 conversion.
The new family of F90 Series LEDs delivers a CRI of at least 90 and R9 of at least 50 (see Table). The F90 2835 0.2W LED has a lumen efficacy ranging from 170lm/W to 210lm/W to meet the DLC (Design Lights Consortium) V5.1 Standard for different lighting products including T8 lamps, troffers, high-bay, linear ambient, and case lighting. The F90 2835 1W LED has a lumen efficacy ranging from 139lm/W to 160lm/W for indoor directional lamps and downlights for commercial lighting. F90 LED products also meet the DLC Premium Lumen maintenance technical requirements of L90≥36,000 hours.
Bridgelux says that F90 Series LEDs can be incorporated in virtually any luminaire (such as linear lamps, downlights, spotlights, high-bay) and can increase the vividness of strong red colors, which is particularly desirable in retail applications.
“By incorporating PFS phosphor to optimize emission spectrum in conjunction with our proprietary packaging technology, the F90 Series of LEDs is able to deliver both industry-leading efficacy and high CRI,” says CEO Tim Lester. “F90 product performance is the same or better than today’s CRI 80 packages,” he claims.
