Abstract

We proposed a new idea for testing the thermal decay of light source under the effect of heat where the lux meter is used rather than using the integrating sphere and the thermal camera is used rather than thermocouple. The thermal decay behavior of the light is detected by using the lux meter. The thermal camera can be used to provide the temperature value as well as the temperature distribution of the measured surface which is more convenient than by using the thermocouple. This fitting model is useful for finding out the decay rate of output light under thermal effect.
