Description

Lighting Control System and Method

The present invention relates to a lighting control system and method, and more particularly, to a lighting control system and method for controlling the illumination of a lighting object in accordance with changes in ambient light environment.

In recent years, countries that are achieving economic growth are increasingly becoming aware of the importance of urban landscapes. In particular, as the city's active time extends to nighttime, 24-hour day and night urbanization occurs in urban space, requiring beauty and comfort.

Therefore, the role of lighting as one of the factors affecting the urban landscape is extremely important. The lighting of the city already applied to open spaces such as roads, buildings, parks, etc. becomes part of the urban landscape, and shows the effect of directing the urban landscape at night.

However, most existing lighting devices are illuminating the object for a certain time according to the lighting sequence, brightness, light color set by the lighting director.

In this case, since the lighting objects such as roads, streets, buildings, urban structures, parks, squares, etc. are illuminated at a constant brightness from sunset to sunrise, they cannot reflect the natural brightness value of the night sky that changes constantly. In addition, changes in the environment, such as entering or dismantling other buildings around the object, or changes in the lighting environment due to the increase or decrease of the brightness of the surrounding buildings, and changes in the weather in areas where the object is illuminated, such as sunny, cloudy or rainy weather It does not reflect the back.

Therefore, regardless of changes in the surrounding environment, most of the lighting devices currently used always illuminate as set by the lighting director, which can waste unnecessary power, reduce the visual perception of human beings, and cause lighting and urban landscape. There is a problem that harm the beauty and comfort of the urban landscape is not achieved.

In addition, when the direction of irradiation is different from the initial design due to deterioration and deficiency of the lamp in the luminaire installed on the lighting object and the wind and vibration of the building, the current technology is the luminaire.
