Development Background

In recent years, UV curing light sources have faced important challenges, including reducing CO2 emissions by decreasing power consumption, lowering ozone emissions, and complying with mercury regulations. Additionally, there is a growing demand for space saving solutions in today’s manufacturing, which has led to a need for more compact light sources with higher curing performance.

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, our product contributes to greater efficiency and reduced environmental impact for various devices used in manufacturing sites, such as printing, adhesion, and liquid gasket.

Features

- 1. Achieves the highest irradiance in its class^*2

By utilizing Kyocera's proprietary ceramic substrate with heat-dissipation as well as a module heat dissipation design that includes a heat sink, we have 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. Additionally, by achieving a total dose of 400 mJ/cm² at 50 m/min, which is an important indicator of curing performance, we have achieved high-speed curing performance comparable to water-cooled UV LED light sources, all within a compact design.

- 2. 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 height 10% lower, placing it among the world’s most compact (120 x 52 x 151mm) UV LED light sources with the same optical performance. The G7A offers a 30mm irradiation window, contributing to space savings while preserving high curing performance.

- 3. Customizable irradiation width to suit a wide variety of printed materials

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. Further, the system can connect to external devices via serial communication, permitting fine adjustments to the LED irradiation width in increments of approximately 30mm.

- 4. Stable operation enabled by monitoring functions for irradiation status

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.

Through the G7A Series, Kyocera will contribute to space saving in a wide range of industrial printing and curing applications, while contributing to a sustainable global environment.
