This paper, the principle that optical transmission occurs by a pattern in a transparent medium was theoretically established, and the change in energy according to the pattern density was considered based on the theoretical equation. In addition, approximately 3,900 pieces were processed such that the projection base area of the right-angled triangle horn σt≃10.8 cm2 and pattern density σt≃10.8/cm2, and the following optical transmission experiment results were obtained. When 40 mW of incident light was irradiated on the optical transmission panel, theoretically calculated results at the first 2 cm were similar at 5 mW, indicating the possibility of theoretically predicting the light transmission results of the fabricated panel. The theoretical calculation at a length of 18 cm showed a difference of approximately 2.3 times between 40.5 mW and experimentally measured 17.2 mW.

This paper proposes a method to process the shape of an optical transmission road and attempts to determine the most suitable single processing method for an acrylic plate optical transmission road. In addition, by manufacturing an automatic pattern processing device to generate certain shapes on the acrylic plate at regular intervals, and measuring the illuminance of the patterned acrylic plate optical transmission road, the measured illuminance was confirmed to fall under the KS illuminance values presented in Table 1. In conclusion, when an incident light of approximately 20,000 lx is applied, the transmission illumination is approximately 200 lx, which represents a transmission rate of approximately 1% for incident light and corresponds to the KS illumination criterion F. Additionally, the right-angle triangular pyramid base size (A) processed at a temperature of 350 °C for one second was 2 mm, exhibiting the largest transmission illumination of 280 lx. When the transparent acrylic plate was set to a constant size of 1.6 mm at the bottom of the right-angle triangular pyramid, the fastest response occurred at a processing tip temperature of 350 °C (0.04 s). On the other hand, it took 10 s to process the size of the bottom of the right-angled triangular pyramid at a temperature of 200 °C to 1.6 mm, and it was confirmed that the optical transmission efficiency was significantly reduced because of the burr that occurred at this time.
