| dc.description.abstract | RGB laser diode is used as the light source to perform the ideal white point of RGB color mixing. A single R light source with a wavelength of 638 nm is 2.5 W, a single G light source with a wavelength of 525 nm is 1.5 W, and a single B light source with a wavelength of 447 nm is 2.2 W. A total of 81 pieces of R light source of 202.5 W, 80 pieces of G light source of 120 W and 33 pieces of B light source of 72.6 W are used to form an ideal white point of 92,500 lm. Design RGB three groups of 4 kinds of light pipes: circle to circle light pipe, corrugated circle to circle light pipe, circle to rectangle light pipe, corrugated circle to rectangle light pipe, observe the efficiency and uniformity on LCOS.
The efficiency of the round-to-round light pipe in the R channel is 40.47%, the average difference is 12.44%, the efficiency of the G channel is 51.99%, the average difference is 8.85%, the efficiency of the B channel is 46.82%, and the average difference is 11.19%. The efficiency of the corrugated round-to-round light pipe in the R channel is 51.82%, and the average difference is 7.33%, the efficiency of the G channel is 52.81%, and the average difference is 7.03%, and the efficiency of the B channel is 49.62%, and the average difference is 7.20%. The efficiency of the round-to-rectangular light pipe in the R channel is 73.82%, the average difference is 28.40%, the efficiency of the G channel is 88.14%, the average difference is 54.12%, the efficiency of the B channel is 84.96%, and the average difference is 35.94%. The efficiency of the corrugated circle to the rectangular light pipe in the R channel is 75.03%, the average difference is 13.24%, the efficiency of the G channel is 88.02%, the average difference is 4.59%, the efficiency of the B channel is 85.14%, and the average difference is 4.92%. | en_US |
