Lighting Laboratory

The lighting laboratory of the BSE Department is allocated in the basement ZB212, Z Block. These rigs cover photometric and colorimetric measurements of lamps and luminaires. One measurement system installed is a spectrophotocolorimeter, which measures the light flux output, colour coordinates, correlated colour temperature, colour rendering indices and spectral power distribution of light sources. This system include two integrating spheres, one 1.5 m and one 0.3 m diameter, with a special coating SPEKTRON which has constant reflectivity (=0.8) over the visible wavelengths 380-780 nm. Another system installed is a goniophotometer for measuring intensity distribution of light sources and luminaires. This goniophotometer measures in the CIE C-g and CIE B-b coordinate systems with a CIE class A accuracy. It includes software for control, measurement and reporting.


The possibility of setting up a professional accredited lighting laboratory to provide training and testing services is being investigated with a lighting software and hardware company in the industry.
