Kyocera Corporation has developed a new air-cooled, UV LED light source that ranks among the smallest in its class – among air-cooled UV LED with a total irradiation of 300 mJ/cm² or more, according to Kyocera research March 2025. The G7A Series, providing revolutionary curing performance for applications such as ink, resin curing and adhesion, will be available in June 2025.
Kyocera’s UV LED light sources not only have a low environmental impact but also adopt an air-cooled system that does not require cooling water, even with high output. As a result, additional equipment such as a water-cooling system is unnecessary, enabling a more compact installation. Through this, the product contributes to greater efficiency and reduced environmental impact for various devices used in manufacturing sites, such as printing, adhesion, and liquid gasket.
G7A Series is achieving highest irradiance in its class
One of the main features of the G7A Series is achieving the highest irradiance in its class – among air-cooled UV LED light sources for UV curing applications according to Kyocera research in March 2025. By utilizing Kyocera’s proprietary ceramic substrate with heat-dissipation as well as a module heat dissipation design that includes a heat sink, it is achieved maximized energy efficiency while achieving an irradiance of 20W/cm² (at 0 mm irradiance distance), the highest among air-cooled UV LED light sources in this class.
In addition, it also contributes to space saving with market-leading miniaturization. Compared to the conventional high-output G5H Series, the G7A Series has a footprint 62% smaller and a 10% lower height, placing it among the world’s most compact (120 x 52 x 151mm) UV LED light sources with the same optical performance.
The G7A 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, by connecting multiple light source units. This enables flexible customization of the irradiation width to suit a wide variety of printed materials.
The G7A Series features monitoring functions via serial communication, allowing for LED temperature, LED current, fan operation time, and accumulated LED lighting hours. It can detect lighting and system errors, and provides notifications for filter replacement and LED lifespan, ensuring stable system operation.
