Examination of LED lighting and lighting control system for night media theme park

Background/Objectives: As LEDs are popularized in general lighting, and have been developed from monochromatic light to various light sources, various productions are possible, and are being applied to night theme parks. Methods/Statistical analysis: We studied the types of LED, how to direct them, and how to control them. We looked at the structure of led lighting, and looked at the basic system and the structure and control method of led which is used a lot recently. In particular, we conducted in-depth research on the control method of driver-integrated leds and also studied the parts connected to control through MCU and various directing programs. Findings: Through this, the shape of lighting can be made more diversified, and the method of composing the system that can be produced more diversely due to the change of control method was examined. It also studied how to use it in a form that is lighter than the existing led control system and can be linked with other lighting systems. In this study, we examined the communication method used in the existing lighting control system and studied the change of the communication method used recently to find out how to integrate and develop the system. We also studied led module control using SPI communication in the way that mainly use DALI and DMX. Control using SPI communication can be controlled by using MCU, which enables fast and diverse production that the existing simple dimming controller did not have. Improvements/Applications: It is necessary to actively cope with changes in the system of the dimmer system through the study of leds that are newly changing from the existing led driving methods and control methods. © 2019 Mattingley Publishing.
