Abstract

The mixed-lamps of bromine tungsten lamps and LEDs were proposed to serve as integrating sphere inner source and LEDs were driven by constant current. Simulated Annealing (SA) algorithm was introduced to study the spectral matching technique of spectrum-tunable integrating sphere light source (STIS). The simulation experiment indicated that mixed-lamps could not only mimic CIE-D65 and equi-energy spectra successfully

but also improve the performance of STIS. The numbers of LEDs reducing 79.8% and 82.9%

respectively

and the average relative error reducing 10% and 40.5%

comparied with LEDs simulation results. A feasible mixed-lamps scheme for

0.5 m integrating sphere

whose maximal radiance between 380 nm and 900 nm is no less than 50 W/(m

sr). The validating experiment indicated that the SA algorithm and constant current drive mode would be feasible in STIS' engineering practice.
