The TrueLight Series Multi-Spectral Standard Light Booth is equipped with 56 carefully selected LEDs of different peak wavelengths, combined with a self-developed core fitting algorithm to accurately simulate the spectra of various lighting scenarios. Its core applications include imaging tests, color reproduction, object color visual evaluation, as well as testing and calibration of cameras and sensors.
The light booth features an innovative fill-light design: multi-spectral light sources on both left and right sides provide fill light for the 24-color chart, improving chart uniformity to over 90%. Additionally, the device supports fill light with fluorescent tubes such as CWF, TL84, and U30, offering flexible adaptation to different testing needs.
Features
More Accurate Reproduction of Standard Illuminant Spectra
With 56 LED channels, it accurately reproduces the spectra of Planckian radiators (e.g., CIE A standard illuminant) within a range of 1,800K to 20,000K, as well as CIE D series standard daylight illuminants. Built-in CWF, TL84, and U30 fluorescent tubes match standard fluorescent lamp spectra.
Improved Uniformity for Left and Right Chart Fill Light
Multi-spectral light sources enable left and right fill light, ensuring better uniformity for the 24-color chart.
Independent LED Channel Control: Precise, Efficient, and Smart
Each LED channel supports 60,000-level illuminance adjustment for precise light intensity control. Single-channel switching takes only 30ms, while multi-channel spectral switching completes within 70ms, ensuring rapid response. With dedicated software, automated spectral switching according to preset time sequences enables smarter operation. The 7-inch touchscreen offers default settings for 100 illuminance levels each for A, H, D50, D65, and D75, 200-level adjustable illuminance for CWF/TL84/U30 fluorescent tubes, and 60,000-level adjustable color temperature for 2,000K/3,900K.
Applications
Imaging Color Reproduction Testing
The 24-color chart is adsorbed to the side wall, and by fitting spectra of various color temperatures and illuminance levels, the color reproduction capability of camera modules is accurately verified, ensuring consistency and accuracy in color performance.
Low-Light Environment Testing
Supports independent adjustment of white light and other LED brightness levels, enabling targeted testing of key indicators such as image clarity and color reproduction in environments below 1 lux, simulating device performance in extreme lighting conditions.
Quantitative Real-Scene Testing: In-Depth Validation Across Multiple Scenarios
The light booth can accommodate various real-scene props, and by adjusting spectra, testing under different color temperatures, illuminance levels, and monochromatic light environments is achieved. Leveraging the fast switching capability of LED channels (within 30ms), dynamic indicators such as the white balance convergence speed of camera modules can be accurately validated, comprehensively covering quantitative testing needs in real-scene scenarios.
Common Light Source Spectral Fitting Performance
Control Methods
Via Touchscreen: Allows direct control for switching the illuminance and color temperature of the 7 default spectra, as well as recalling any of the 100 spectra settings saved by the user.
Via PC GUI: Utilizes dedicated graphical interface software for computer-based control. This enables direct operation of the light source and compatible spectrometers, facilitating functions such as spectrum generation, switching, sequence (timing) control, and offers unlimited saving of configuration settings.
Via API for Secondary Development: Provides an Application Programming Interface (API) (C, C++), allowing for direct remote control of the light source through custom code for integration and automation purposes.
