G7A Air-Cooled UV LED Light SourceRevolutionary curing performance and compact size

G7A

Achieves a peak irradiance of 20 W/cm² and a dose of 400 mJ/cm²

Peak irradiance of 20W/cm² (at UV wavelength 385nm/395nm and working distance of 0mm) with air-cooling is achieved by using a high heat dissipation ceramic substrate and optimizing the design of the heat sink to maximize energy efficiency. Capable of achieving 400mJ/cm² (at 50m/min) dose, which is comparable to the dose level provided by a water-cooled UV LED light source.

Compact size contributes to space saving(Compared to G5H: a 62% smaller footprint and a 10% lower height)

Compact size (120 × 52 × 151mm) has been achieved by reducing the footprint by 62% and the height by 10% compared to the G5H series. The irradiance window size is secured at 30mm, contributing to space saving while maintaining revolutionary curing performance.

Scalable structure for flexible customization of the irradiation width

The G7A UV LED Light Source has a scalable structure in 120mm increments, allowing the irradiation width to be adjusted from a minimum of 120mm to a maximum of 2,400mm. This enables flexible customization to meet a wide variety of printed materials. Serial communication with external devices is available. ON/OFF power switching at about 30mm units allows optimization and flexibility in selecting the irradiation width and area according to the target to be printed.

Monitoring functions for stable operation

The G7A Series features monitoring functions via serial communication, allowing for LED temperature, LED current, fan operation time, and accumulated LED lighting hours. Can detect lighting and system errors and provides notifications for filter replacement and LED lifespan, ensuring stable system operation.

Three connected units of G5A

High-irradiance and dose

Peak irradiance of 24W/cm² (at UV wavelength 385nm/395nm) with air-cooling is achieved by use of high heat dissipation ceramic substrate and optimizing the design of the heat sink to maximize energy efficiency. Capable of achieving 270mJ/cm² (at 50m/min) dose, which is comparable to the dose level provided by water-cooled UV LED light source.

Compact and lightweight design allows more flexibility for mounting

Scalable structure

The G5A UV LED Light Source is scalable in 80mm increments to a maximum irradiation width of 1,600mm to meet various curing job requirements. Serial communication with external devices along with ON/OFF power switching at 26.5mm units is available, allowing optimization of the irradiation area.

Monitoring functions for stable operation

Monitoring functions: LED temperature, LED current, fan operating hours, and accumulated LED lighting hours. Alert functions: System error, LED lighting error, air filter replacement, etc.

Print quality improvement by pinning process

Curing inkjet inks by each colors (pinning) will prevent unwanted ink spread and color mixture, improving the print quality.

G5AN/G5HN Air-cooled UV LED Light Source(Nitrogen Purging Model)
Dramatically increases the acceptance of wider range of inks.

G5AN

G5HN

Have you ever experienced "We considered the introduction of a UV LED light source, but abandoned the idea because of insufficient curing with existing inks"? It may be due to "oxygen inhibition" caused by the combination of radicals generated by UV irradiation with atmospheric oxygen.
Kyocera has developed a UV LED Light Source that realizes excellent curing performance without relying only on power such as irradiance and integrated (or accumulated) light amount, in particular, against "oxygen inhibition" known as poor curing of the ink surface.

Compatible with wide range of inks

Excellent curing performance even for inks and resins that are difficult to cure with conventional UV LED light source, such as low migration inks, coat varnishes, and inks for metal halide lamps.

Integrated structure with Kyocera UV LED Light Source (G5AN/G5HN)

Unlike the conventional nitrogen purging system that requires an enclosed space, G5AN/G5HN can efficiently flow nitrogen and reduce oxygen concentration in UV irradiation area simply by installing it in the system. No major modification to the system is required to create an enclosed space. A separate nitrogen supply source such as a nitrogen generator is required.

Scalable structure

The irradiation width can be extended to match the print size (80mm to 1,600mm) by 80mm width scalable unit structure.
