UV gallium lamp for screen printing

Out on the line, you’ve got a screen-printed water treatment panel staged and ready. But the whole job doesn’t move until the disinfection unit proves it can knock out bacteria in one pass. Flow rates are locked. Dwell time isn’t a discussion. Under-dose, and you’re staring down a recall. So you need a UVC source that hits lethal irradiance in seconds, not minutes. What matters, technically We built the UV gallium lamp for screen printing around a low-pressure mercury-gallium amalgam approach, tuned for 254 nm germicidal output. Peak irradiance is engineered to clear 150 mW/cm² at the target plane, giving you the 40–80 mJ/cm² dose in about one second, even with water moving. The quartz arc tube and the dichroic-coated reflector keep the beam collimated—less divergence, more intensity across the full print width. It runs ozone-free, and lamp life is targeted at 9,000 hours with controlled output decay. Here’s why it fits. In water treatment modules, the lamp sits right in the flow channel, immediately after the screen-printed sensors and housings. The 254 nm photons punch through microbial membranes and hammer nucleic acids, delivering log reduction in milliseconds at practical flow velocities. On the press, that same spectral discipline means fast ink curing, while the downstream disinfection chamber hits sanitation targets without throttling throughput. Power draw stays low, and the footprint fits tight spaces. A few shop-floor notes. Match lamp length, arc gap, and reflector geometry to the specific screen-printing machine and the disinfection chamber footprint. Water clarity and UV transmittance set the dose—fouling on the quartz sleeve will eat output, and you have to manage it. Check ballast compatibility, connector type, and cooling direction. And keep a schedule for intensity audits with a calibrated radiometer so you stay on spec.
