L.E.S.S., a Switzerland-based designer and manufacturer of technical lighting systems, has raised $22M in Series C funding. The company uses proprietary LuxiBright nano-fiber technology to deliver thinner, brighter, more uniform light than LEDs for machine vision inspection, medical devices, and automotive applications. The oversubscribed round will scale production and commercialization across these markets.
Machine Vision Lighting Scales Up
The funding arrives as the machine vision lighting market grows from $1.87B in 2024 to $3.65B by 2032 at 8.73% CAGR. Advanced Illumination, a key competitor, was acquired in 2022 by Exaktera. L.E.S.S. differentiates with nano-fiber tech that eliminates LED hotspots and heat, targeting precision gaps in semiconductors and pharma inspection.
LEDs Fail Uniformity Test
Machine vision systems detect defects at micrometer scales, but traditional LED lights create hotspots and glare, reducing OCR accuracy by up to 20% in some cases. Automotive OEMs need sub-millimeter slim profiles impossible with bulky LEDs. Current solutions also generate excess heat, complicating cleanroom pharma inspections affecting 30% of production lines.
Nano-Fiber Enables Uniform Glow
L.E.S.S.'s LuxiBright hybrid nano-fiber produces directional, uniform illumination without diffusers, 4x thinner and 5x lighter than LEDs. Products like LuxiRing MINI/MAXI reveal invisible scratches on wafers and PCBs, boosting inspection yields. Unlike CCS Inc. structured LEDs, LuxiBright handles overdrive modes for 5x brightness peaks.
As Yann Tissot, CEO noted:
"In a demanding market and challenging environment, closing an oversubscribed financing round, is a powerful vote of confidence in our strategy and execution. With key milestones achieved in recent months, we are now ready to accelerate at scale."
Oversubscribed Round Signals Confidence
The CHF 17M ($22M) round exceeded its target, following the world's first series production vehicle integration in Lanzante's 95-59. Backers validate L.E.S.S.'s shift from prototypes to OEM-scale manufacturing. This growth capital supports vertical integration from R&D to production amid Industry 4.0 automation.
Inspection Market Eyes $3.65B
The broader machine vision market stands at $23.5B, growing at 11.2% CAGR through 2026. Competitors like Smart Vision Lights focus on high-intensity LEDs without nano-fiber uniformity. L.E.S.S. captures demand from AI-driven 3D imaging and edge computing in electronics and autos.
Photonics PhDs Drive Innovation
CEO Yann Tissot holds a PhD in Photonics from EPFL and led products at Optotune in adaptive optics. Co-founder Simon Rivier brings a Physics PhD with expertise in nanostructures and OLEDs from Freie Universität Berlin. Their EPFL roots and 15+ years in optics directly fuel LuxiBright's breakthroughs over LED incumbents.
Automotive Production Fuels Expansion
Post-funding, L.E.S.S. launched LuxiRing variants for semiconductors and hired sales reps for France and DACH regions. The Lanzante 95-59 partnership marks series production entry, with plans for Asia via events like Vision China. Team growth targets machine vision integrators and OEMs.
