How does the LLG-3P-3 reduce cycle time on three-joint assemblies?

The Incure LLG-3P-3 cures all three bond joints in a single trigger event. A single-pole guide would require three sequential exposures — three trigger events, two part-repositioning or tip-repositioning steps, and three waiting periods between activations. The trifurcated guide eliminates two of those trigger events and all repositioning steps, curing all three joints simultaneously in the same cycle time as one single-pole exposure.

What cable lengths are available for the LLG-3P-3?

The Incure LLG-3P-3 is available in two cable lengths: 1,000 mm and 1,500 mm. These lengths suit compact three-station fixtures where each pole tip must reach a separate bond point within the fixture envelope. For longer reach requirements on a three-joint assembly, contact Incure to discuss configuration options.

Does splitting the lamp output into three poles affect cure quality?

Splitting the source output across three poles reduces the per-pole intensity to approximately one third of the lamp's total output. The simultaneous exposure still delivers consistent UV dose to all three joints — dose uniformity between the three bond points is inherently better than sequential single-pole exposure, where operator timing, lamp warm-up state, and trigger timing can introduce inter-joint dose variation. Adjust exposure time or lamp power to maintain the required dose at each joint.

What applications typically use the LLG-3P-3?

The Incure LLG-3P-3 is used on assemblies with three UV cure points that must be cured in a single cycle — tri-pole connectors, three-junction sensor housings, triangular gasket seal patterns, and multi-bond optical subassemblies. Any three-joint assembly where sequential curing is too slow or introduces part-movement risk between exposures benefits from a single simultaneous trigger cycle.

What light sources are compatible with the LLG-3P-3?

The Incure LLG-3P-3 is compatible with mercury arc, xenon, and halogen spot curing lamps. For UV LED spot curing with multi-pole delivery, use the Incure L9000™ lightguide series, which supports up to 4 lightguides from a single controller.

Trifurcated Liquid Light Guide — Incure LLG-3P-3

Name: Incure LLG-3P-3 Trifurcated Liquid Light Guide
Brand: Incure

Incure LLG-3P-3 cures three bond points in one trigger cycle — two fewer exposures than covering the same three joints with a single-pole guide, and one more simultaneous point than the LLG-2P-3. Each of its three output poles carries a 3 mm core delivering UV from 300 nm through the visible range, in 1,000 mm and 1,500 mm cable lengths. Compatible with mercury arc, xenon, and halogen spot curing lamps.

Three Cure Points in One Trigger Cycle — Two Fewer Exposures per Three-Joint Assembly

On a three-joint assembly, a single-pole guide demands three sequential trigger events — three activations, two repositioning steps, and three cure intervals, all executed in sequence. The LLG-3P-3 delivers UV to all three bond points simultaneously in a single trigger cycle. The total exposure time equals one single-pole cure instead of three, and the part does not move between bonds. For high-volume three-joint assemblies, this is the highest-throughput liquid light guide configuration available from a single lamp controller.

Uniform UV Dose to All Three Joints — Eliminates Exposure Variation Between Bonds

Sequential single-pole curing introduces inter-joint dose variation whenever trigger timing, lamp warm-up state, or operator consistency differs between the first and third bond on the same part. The LLG-3P-3 cures all three joints from the same lamp cycle, with the same irradiance, at the same moment. Each bond on the part receives identical UV dose — a prerequisite for consistent adhesive cure performance across all three joints and for process validation documentation that requires dose uniformity.

3 mm Core per Pole — Precision Three-Point Cure From 1,000 mm

Each of the three output poles delivers a 3 mm cure spot, concentrating UV at the bond face without irradiating adjacent components. The 1,000 mm minimum cable length suits compact three-station fixture geometries. The 1,500 mm option accommodates fixtures with wider separation between the bond points and the lamp controller mounting position.
