摘要

It is commonly observed that the LED projectors can provide with more perceived brightness by less stimulus luminance. In this work, the Helmholtz-Kohlrausch effect is applied for studying the enhanced perceived brightness of the LED projector. According to the equations developed by Nayatani’s group, the ratio of the enhanced perceived brightness of LED projector is evaluated as 25% to 30% as compared to traditional lamp projector in dark environment. However, in the normal office illumination level, the difference between the LED projector and the lamp projector diminishes.
