Abstract

The development, production and application of Light Emitting Diodes (LEDs) have increased tremendously in the last ten years. All the special and useful properties of the LEDs are accompanied by their commensurate problems in measuring the light output. The spectrum of LED is quite different from the conventional incandescent source. In this paper we will examine the location of the LED in the integrating sphere when measuring the total flux output of the light source. We set up a mode of integrating sphere and a narrow bean light source by a photic design software. The conclusion from theoretical derivation and software simulation shows that the tested LED can be placed on the wall of the integrating sphere, and the wall location is much more suitable for LED rather than center position.
