Kyocera has launched its new G7A Series UV LED light source. The light source is designed for use in curing applications such as ink, resin, and adhesives, and features a compact air-cooled design delivering high irradiance and energy efficiency.
In response to growing industry demands for reduced environmental impact and space-saving solutions, the G7A replaces traditional water-cooled systems with an air-cooled design that eliminates the need for external cooling equipment. Kyocera said this approach simplifies installation and reduces power and water usage, aligning with global efforts to minimise carbon emissions and eliminate mercury-based technologies.
Kyocera’s G7A achieves an irradiance of 20W/sqcm at zero distance, making it one of the highest-performing air-cooled UV LED light sources in its category, claimed the company. The system also delivers a curing energy of 400mJ/sqcm at a speed of 50m/min, enabling performance comparable to more complex water-cooled alternatives.
The device is built using Kyocera’s proprietary ceramic substrate and an integrated heat dissipation system, including a specially designed heat sink. This engineering allows for a compact footprint – 62% smaller and 10% lower in height than the company’s previous G5H Series. The unit measures 120 x 52 x 151mm and includes a 30mm irradiation window.
According to Kyocera, a key feature of the G7A Series is its modular design. Units can be connected in 120mm increments, enabling customisable irradiation widths ranging from 120mm up to 2400mm. Additionally, the system supports external serial communication, allowing for precise control of LED output and real-time system monitoring.
Monitoring functions include tracking of LED temperature, current, fan operation, and total lighting hours. The system can alert users to filter replacement needs and potential failures, helping ensure consistent operation and reducing maintenance downtime.
