Paper Abstract

A new light source was researched and designed for cultural relic illumination. It is composed of high bright red, green, yellow, bule and white LED. A cone axes ellipse reflector is used in order to utilize light energy of LED as early possible. The light transmits in optical fiber bundle and lights the cultural relic in different angles and directions. The spectrum of the whole light source system is from 410nm to 700nm. There are not IR and UV. The light illuminance is 301x. Lighting of LEDs is controlled by rectangle waveform constant current source to make temperature lower and efficiency of light higher. Noise is avoided because a wind-cooling device is not used. Spectrum energy of different color light can be adjusted easily in order to show the important point of cultural relic.
