Lighting laboratory facilities

The lighting laboratory of the BSE department is being relocated to the newly acquired space FJ001. In this new laboratory space, two main pieces of lighting measurement equipment will be installed. These will be installed during the first quarter of 2006. These rigs will cover photometric and colorimetric measurements of lamps and luminaires. One measurement system to be 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 will 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 to be 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.
