Fusion Light Hammer 10

Operating in the power class of 600 watts/inch, the Light Hammer® 10 features two easy-to-service modular components: the microwavepowered irradiator and the solid-state power supply. At the heart of Fusion UV’s technology is the electrodeless bulb mounted in an elliptical reflector for focusing an intense strip of light 53 mm (2.1 inches) below the face of the lamp. Offering many advantages over traditional drying methods, our systems have been shown to increase production speed, reduce reject rates, improve scratch and solvent resistance, and facilitate superior bonding.

Higher Efficiency from the Solid-State Power Supply

Each lamp system has its own microprocessor-based, modular power supply. The high voltage circuit inside the power supply consists of a solid-state, switching engine. This reduces ownership costs because it extends the life of the magnetron and the bulb by supplying a constant non-fluctuating source of power to the lamp. The solid-state electronics run cooler and more efficiently – saving money on power, reducing environmental noise and space requirements. Power output from 35% to 100% can easily be controlled from the front panel or remotely through a PLC (programmable logic controller). This variable power feature permits matching of the lamp output to the machine/line speed or to the ink/coating demands.

Built-In Communications Software

Utilizing DeviceNet™, our sophisticated control system allows multiple lamp systems to be interconnected and controlled individually or as a group. It also allows the collection of system operation data that will enhance preventative maintenance and line productivity.

Improved Cure

The ultimate benefits of the Light Hammer® 10 are the achievement of higher degrees of conversion, higher speed and better depth of cure than is typically achieved with other UV sources. (Process patents: US 6908586B2 and US 7037460B2)

Electrodeless Technology

The microwave-powered lamp and its electrodeless bulb technology have proven themselves over time and in hundreds of demanding applications. These long life bulbs are known for their stable performance, high intensity and low maintenance operation.

Fast UV Curing from High Peak Irradiance and Low Infrared

The small diameter bulb combined with the elliptical reflector provides high peak of UV irradiance for highspeed cure. The small diameter bulb also reduces infrared emission resulting in lower surface temperatures of the substrate, thus eliminating the need for complicated heat removal methods.

Popular Bulb Spectra Available

The standard bulb spectra are available: “H” spectral distribution is suited for clearcoats and varnishes; the “D” spectral distribution is popular and proven for inks and thick coatings or adhesives; and the “V” distribution is effective in the UV curing of white basecoats, through laminating materials and in other specialty applications.

Multiple Lamp Systems

To operate multiple lamps in a system, a controller with master DeviceNet™ compatibility is required.
