The demand for higher-performance lighting for visual color control and quality testing has increased significantly in recent years. This is driven by limitations of fluorescent tube-based lighting, quality fluctuations between production batches, limited lifetime, and the EU decision to ban these tubes. Already, more than 50% of JUST Normlicht systems sold are LED-based - and the trend is growing.
To reduce the time and cost of upgrading to JUST Digital Light Systems (DLS) LED-based technology, we offer solutions that maintain the cabinets of existing color inspection stations, while upgrading the lighting with a bolt-on replacement. This green approach saves resources while reducing costs. The DLS upgrade systems are less expensive than a completely new LED-based station, while retaining all of the JUST DLS advantages. There are no tubes to change and cost-of-ownership is less than half that of other solutions.
Replacing a fluorescent tube with an LED tube is an expensive, difficult, and feature-less change. Reflectors in existing light booths are designed to handle the 360° light output of a fluorescent lamp. LED replacement tubes have a very narrow light distribution (around 120°) which is incompatible with those reflectors. The requirements for brightness and homogeneity are not achieved. The illumination becomes streaky and creates light and dark "spots" and “bands” on the viewing surface unless the booth or station is fundamentally optimized for those tubes. Further, the wiring of existing booths much be changed by a license electrician, an expensive process that may also removed the manufacturer's liability or warranty.
Replacing fluorescent tubes with LED tubes can lead to several issues and may not comply with ISO standards. Existing fluorescent tube cabinets and stations are designed to utilize the 360° light distribution of fluorescent tubes. In contrast, LEDs typically have a much narrower light distribution, which can result in uneven illumination, such as bright and dark stripes, if not properly optimized.
Furthermore, LED replacement tubes are not calibrated after manufacturing. This lack of calibration leads to inconsistencies between batches and across different installations, similar to the problems often encountered with fluorescent tubes. Additionally, unlike fluorescent tubes, LED tubes cannot be recalibrated during their lifespan. As a result, costly replacements of LED tubes may become necessary over time.
JUST offers turn-key DLS Upgrade solutions both for many JUST fluorescent stations . They are designed to make the upgrade process as simple as unbolting the old luminaire and bolting-on the new one. Plug in and you’re ready to go. It’s time to “save the iron and see the light”.
