Lighting Cabinet, Multi-channel LED, Daylight & Blackbody Simulator, Image Evaluation, Camera Calibration, Visual Assessment
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)
To reproduce any phase of daylight with highest quality on the market in terms of Color Rendering Index (CIE Ra) 99 and Metamerism Index (MI) Grade A
All the simulated illuminants sources can have the same light intensity, or customer specified
It provides a uniform and flicker free lighting environment
Much longer lifetime compared to fluorescent technology, and optimized heat management guarantees excellent long term stability
Conforms to all major international standards, including ASTM D1729, ISO 3664 as well as DIN, AATCC and BSI standards
LEDView hardware can save up to 80 LED sources, which can be switched via touch screen controller, and LEDNavigator-LV software can reprogram the LED sources in hardware
LEDView-C15 and LEDView-I14 can achieve max >2500lux on the bottom plate, and LEDView-H11 can achieve max >12000lux on the bottom plate. The intensity of LED source and fluorescent is dimmable
To accurately reproduce a range of sources from tungsten and daylight, with customized CIE Ra and Duv
To accurately reproduce any measured or imported SPD to record or reproduce any light you want. It is easy to spread SPD files between different locations for light communication
Arbitrarily control the intensity of each channel in LEDView to design any light wanted
Programmable illuminant light sequence and interval
Maintain the same light quality, compensating for age and variable environments with external micro-spectrometer
Provide LED channel wavelength selection service from UV, VIS to NIR

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.
Currently, LEDNavigator-LV only supports Windows OS, including Win XP, Win7, Win8 and Win10.
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.
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.
Yes, THOUSLITE provides software customization service, please contact THOUSLITE or its distributors for detail.
