LEDView Lighting Cabinet

THOUSLITE LEDView products are epoch-making lighting cabinets based on the multi-channel LED technology. It is specially developed for color and imaging industry, including textile, coating, plastics, printing, graphic arts, imaging etc.LEDView gives consistent viewing conditions for color assessmen, quality control, sensor evaluation, etc.By using a set of high power LEDs and our proprietary LEDNavigator-LV software, it can achieves the match to any desired SPD (Spectral Power Distribution), including daylight illuminant with best lighting quality. lt guarantees "what you see is what you measure". LEDView products have four models, including LEDView-Portable (12 channels, general visual assessment), LEDView-C15 (15 channels, color and lighting research), LEDView-l14 (14 chan­nels, camera evaluation & sensor calibration), and LEDView-H11 (11 channels, high intensity)

FAQs

  • Can LED channels in LEDView be customized or replaced?

    Yes, THOUSLITE provides LED channel wavelength selection service from UV, VIS to NIR for LEDView-Ultimate, please contact THOUSLITE or its distributors for detail before order.

  • What Operating System is LEDNavigator-LV compatible with?

    Currently, LEDNavigator-LV only supports Windows OS, including Win XP, Win7, Win8 and Win10.

  • Why the LEDNavigator-LV sometimes cannot find LEDView hardware during connection?

    Firstly, please make sure the LEDView are turned on, the USB cable and dongle is connected to the PC, and the LEDView driver is installed correctly in first use. Secondly, restart the hardware LEDView and software LEDNavigator-LV. If multiple restart doesn’t work, please contact THOUSLITE or its distributors.

  • Why the matched light source become worse compared to target light source after feedback?

    There are two possible reasons: ①unnecessary manipulation of feedback: if the original matched light is already very close to the target, say CCT difference smaller than 50K, a feedback manipulation may give worse result; ②Since the feedback is based on the latest measure result, please make sure you have measured the light before using feedback.

  • Can users customize more features in software?

    Yes, THOUSLITE provides software customization service, please contact THOUSLITE or its distributors for detail.
