Recently Visitech were granted a European patent called: Light source comprising a digital regulator, patent No. EP 2312309A1.


This patent protects the digital driving / regulating of the pulsed LED current in our DLP Systems. This is especially important for our PCB Lithography system, the LUXBEAM LITHOGRAPHY SYSTEM – LLS, with digital LED pulsing.

Other applications with tough requirements for accurate pulsing and current control will also benefit from the flexible digital control.

Further, the patent also covers solutions with high dimming rate of image brightness, while keeping colour balance. This is a function especially important in applications like Head-up Display  – HUD.
