Abstract
The film of holographic two-dimensional (2D) photonic crystal is used for the led illumination system. According to the decorative patterns, the structure sizes of 2D photonic crystal and relevant led luminaire have been reasonably designed. Then the master mask of 2D photonic crystal is produced with the method of multiple-beam interference. With the experiment of LED illumination, the results show that it is able to meet the expected decorative patterns of LED illumination. While the master mask is used to copy optical coating of polycarbonate, it will provide a better option for LED decorative illumination under low cost.
