Lighting lights such as streetlights and security lights are being illuminated outside the required area, disturbing the ecosystem of nature. In the case of LED lights that replace existing lighting lights, steering analysis and simulation of BUG (Back light, Up light, Glare) control technology that can prevent light pollution by securing left and right light, controlling light in the front and rear, and controlling upward light to prevent disturbance of the ecosystem of nature are performed. By doing so, we present an algorithm that can secure light from left to right, control light from the front to the back, and control light from the front and rear, and efficiently control upward light in the case of LED lighting. Through this, it is possible to effectively prevent light pollution through BUG control of nature-centered light environment and optical performance, such as reducing energy, and securing a uniformity of light pollution problems and the generation of lighting blind spots of conventional LED lights. As a result, it is possible to effectively prevent light pollution through BUG control of natural light environment and optical performance, such as securing a uniformity system for light pollution problems and the generation of lighting blind spots such as conventional LED lights. Various applications of lighting devices have recently been made possible based on powerful light sources through power LED devices. However, from the perspective of nature, industrialization and urbanization have destroyed the living grounds of many living things that coexist with humans, and in turn, they have come to realize that the harm can be brought back to humans. In particular, plants suffer from abnormal growth pains and fatigue syndrome because they cannot distinguish between night and day by using artificial lighting to excessively expand the lighting area to maintain bright conditions as day at night, and many scientific studies have shown that nocturnal animals are unable to hunt or mate properly as the food chain changes, resulting in disturbance of the ecosystem. For example, the use of LED lighting technology is applied according to the location and direction deemed essential, as migratory birds are lost, lost, or recovering from heartless poverty, reducing the population, or cicadas crying until late at night become pollution factors that destroy the natural ecosystem.
