Features

Characteristics of Kyocera UV LED Light Sources

High-density mounting and high heat dissipation accomplished by Kyocera’s ceramic substrates

High-density mounting of LED chips produces high-output irradiation. Kyocera's low-thermal resistance ceramic substrate improves heat dissipation and allows high density mounting of LED chips.

Product design optimized by simulation
Kyocera's UV LED Light Sources are developed by using optical simulation to optimize irradiance, focus distance, and surface uniformity as well as fluid simulation to optimize the characteristics of heat dissipation and the positioning of components.
Customized Products
In addition to our standard products, we offer custom products. Please contact your local Kyocera representative for more information.

G5A Air-cooled UV LED Light SourceCompact and lightweight design with high-irradiance

3 units of G5A connected

High-irradiance and dose
Peak irradiance of 24,000mW/cm2 (at UV wavelength 385nm/395nm) with air-cooling is achieved of high heat dissipation ceramic substrate and optimizing the design of the heat sink to maximize energy efficiency. Capable of achieving 270mJ/cm2 dose, which is comparable to the dose level provided by water-cooled UV LED Light Sources.
Compact and lightweight design allows more flexibility for mounting
Compact (80.3 × 88.0 × 150.5mm) and lightweight (1.0kg) design allow more flexibility when incorporating this UV LED Light Source into a system. The G5A Light Source's ability to achieve high-irradiance with air-cooled design eliminates the need for a water-cooling system (chiller) which is required for water-cooled high-irradiance light sources.
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.

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

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 (G5AN) 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 Sources, such as low migration inks, coat varnishes, and inks for metal halide lamps.
Integrated structure with Kyocera UV LED Light Source (G5A)
Unlike the conventional nitrogen purging system that requires an enclosed space, G5AN 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.
