About the Laboratories

Intelligent Space Lab (IB-1039)

The laboratory focuses on interactions between new-type lighting, display device and human eye in a living house. In this laboratory, the walls and the floors have embedded 34 light sensors, as well as using a variety of high performance color measurement devices to observe the interaction among lighting equipment, color device and the human emotions. Through a combination of different lighting and audio-visual devices, it is possible to simulate the living environment of general people, and find out the most suitable combination between the indoor ambient light illuminance and color temperature.

 

Total Appearance Measurement Lab (IB-1042)

The lab aims to provide measurement of the bidirectional reflectance distribution function (BRDF) of opaque surfaces. The measurement helps to define how colored light is reflected at surfaces of various materials and textures in order to meet specific design requirements. The lighting condition of the lab is strictly dark to meet requirements of the BRDF measurement. In addition, the lab is also equipped with psychophysiological measuring instruments, such as the electroencephalography (EEG) measurement.

 

Radiation Metrology Lab (IB-1043)

The purpose of this lab is to construct a complete optical radiation measurement technology platform, and aim at providing the optical testing equipment and the environment for topics in lighting and color. The existing major equipment includes: integrating sphere type standard calibration light source, CCD-based imaging colorimeters, illuminance chroma meter and spectrometer. Lab has also set the vibration isolation optical table as well as light source device fabrication and testing platform. In the future, we will continue to purchase the total luminous flux, luminous intensity distribution, spectrum and chromaticity measurement system.

 

Living Environment Lab (IB-1044)

The lab aims to simulate a real lighting scene of living space, which offers varied kinds of experimental environments for measures and researches of space perception and space mood. The interior design of space configurations is based on the general activities during day-and-night. There are equipped main illuminants are T5 pendants, MR16 recessed, RGB color-changing LED floodlight, RGB full-color LED light bar, etc. And two display systems are set in the space, one is LCD TV and other is a rear projection system which combines a wide-gamut projector and a smart film glass.

 

Color Design Lab (IB-1045)

The lab aims to support advanced research on accurate measurement of materials’ total appearance including spectral reflectance, glossiness, texture and 3D shape et al. The lab not only has various measuring instruments and calibration targets, but also provides standard light sources to perform color rendering studies for solid-state lighting. The lab also collects a large number of color samples with different surface properties for related studies.

 

Lighting Assessment Lab (IB-1046)

This lab provides a simulation environment for assessing the human reading performance under various lighting conditions. The lab is equipped with several reading materials that have different surface reflection and contrast such as traditional books, magazines, e-papers, hand-held devices, photo frames et al, and used for evaluating the degree of visual comfort and reading performance. The light source on the ceiling and the desktop is consisted of LED arrays and can be readily remodeled for various lighting scenarios. In addition, the lab is also equipped several physiological measuring instruments, such as heart rate variable (HRV), critical flicker frequency (CFF), biophysical data acquisition (EMG, ECG, EEG), color weakness, visual inspection, stereo depth-perception tests and eye tracking, for objectively monitoring the physiological data the subject when he or she is reading documents. Then, questionnaires are designed for subjectively verifying and analyzing the preference of reading behaviors. The major mission of this lab is to assessing the quality lighting design based on the functional, intelligent and ergonomic requirements.
