Every production line curing UV adhesives or coatings eventually hits the same fork: stay inside a controlled-environment chamber, or move to open-floor, conveyor, or fixture-mounted equipment. In the L-Series™, that fork has a specific model number attached to it.
The First Model Beyond the C-Series™ Chamber Envelope
The Incure L64 is a 6″ × 4″ UV LED flood curing lamp built on a 216-LED array, and it’s the first model in the Incure L-Series™ that exceeds what any current Incure C-Series™ chamber can accommodate — including the C191C, the largest chamber in the range. Where the L44 below it is the ceiling for chamber-compatible curing, the L64 is designed from the outset as a standalone flood source: mounted on a bench fixture, integrated into a conveyor line, or set up on a custom production jig, rather than housed inside an enclosure.
50% More Area Than the L44 at the Same Peak Output
The L64 delivers 24 sq. in. of coverage — 50% more than the L44’s 16 sq. in. — at the same 1,900 mW/cm² peak intensity class the L88 and L1010 also use (385/395/405 nm), stepping down from the L44’s 3,100 mW/cm² as the array spreads across a substantially wider zone. Applications that outgrew the 4-inch chamber-based workflow move to the L64 without needing to reduce their curing area to fit an enclosure — the trade is chamber protection for open-floor flexibility, not a reduction in coverage.
A Non-Square Footprint Built for PCB Panel and SMT Formats
Unlike every smaller L-Series™ model, the L64’s 6″ × 4″ irradiation zone is rectangular, not square. PCB panels, multi-row SMT assemblies, and rectangular adhesive patterns frequently fit a 6-by-4 envelope more naturally than a square array of equivalent area — the L64’s footprint aligns with these common production geometries directly, covering the full work area in one pass without the lateral waste a square array of the same coverage would introduce on a narrow panel.
1,900 mW/cm² From a 216-LED Array
Peak irradiance at a 2-inch working distance is 1,900 mW/cm² at 385, 395, or 405 nm, and 1,600 mW/cm² at 365 nm. Static uniformity holds at 0.78 at 2.0 inches. The control interface carries the same LCD front panel, foot-switch input, and PLC digital I/O as every smaller L-Series™ model — but unlike the L44 and below, the L64 has no C-Series™ chamber pairing option; it’s built for open installation from the outset.
Physical Mounting for Standalone Operation
Because the L64 has no chamber housing to sit inside, fixture engineering has to handle what the chamber would otherwise provide — a stable mount, defined working distance, and some form of stray-UV containment around the beam path. Custom production jigs built for the L64 typically incorporate a bracket or slide mechanism holding the lamp at a fixed 1-to-3-inch working distance above the part, along with localized shielding rather than a full enclosure, since a full chamber isn’t an option at this footprint. Planning that mounting hardware as part of the initial L64 purchase, rather than as an afterthought once the lamp arrives, avoids a gap between equipment delivery and actual production readiness.
Integrating the L64 Into a Production Line
Because the L64 isn’t chamber-bound, it’s a natural fit for inline curing on a moving line rather than a static batch process. A CDM™ UV conveyor integrates flood lamp heads directly into a continuous-flow production line, and reviewing line speed against the L64’s exposure requirements is a useful step before committing to a conveyor-based layout. For comparison, an arc-lamp alternative in a similar footprint class is available through the Incure F-Series™ — worth reviewing if broad-spectrum mercury arc output better matches an existing adhesive’s photoinitiator system than the L64’s LED wavelength options.
Matching adhesive or coating chemistry to the L64’s open-floor exposure geometry — rather than a chamber’s controlled, light-tight environment — sometimes changes cure-time assumptions, particularly for ambient-light-sensitive formulations. Email Us with the current process details for a review before moving a chamber-based process to open-floor L64 curing.
Uniformity and Working Distance at a Rectangular Footprint
Static uniformity of 0.78 at a 2.0-inch working distance applies across the L64’s full 6″ × 4″ zone the same way it does on the square L-Series™ models, but a rectangular array asymmetry is worth confirming during fixture commissioning specifically — a panel positioned slightly off-center along the shorter 4-inch axis has less margin for error than one centered along the longer 6-inch axis. Verifying actual cure uniformity across a representative panel at the intended working distance, rather than assuming datasheet uniformity translates directly to every part orientation, is a reasonable qualification step before locking in a production fixture layout.
Eye and Skin Protection on Open Installations
Because the L64 runs without a chamber’s UV containment, operator protection matters more here than on any smaller, chamber-housed L-Series™ model. Incure Vison™ UV-blocking eyewear is rated for the full L-Series™ wavelength range and should be standard equipment on any open-floor L64 installation, alongside physical shielding around the beam path where operators work in proximity to the fixture.
