Description

Color temperature variable smart control system {Smart Control System with variable LED Kelvin Temperature module}

The present invention relates to a color temperature variable smart control system, and more particularly, to light distribution by appropriately converting and adjusting the color temperature and brightness of an LED light according to weather conditions such as rain, snow, fog or haze, weather conditions on roads, or changes in circumstances. The present invention relates to a smart control system capable of minimizing glare obstructing the vision of drivers and pedestrians and increasing visibility by doing so.

In general, road lighting is installing light sources of relatively high capacity at regular intervals for the purpose of preventing accidents and crimes due to safe driving of vehicles at night.

However, uniform LED lighting that does not respond to road surface conditions and weather conditions causes glare to drivers and pedestrians, obstructing vision, and improving the driver's ability to recognize objects and visibility, such as inability to detect lanes and obstacles. degradation may occur.

For example, when it rains, when a water film is created on the road surface and glare occurs, when there is light scattering due to thick fog on the road, the light from the lighting rather obstructs the driver's vision and causes damage to the road. In natural adverse weather conditions, such as when lane recognition is difficult, there is a problem in that the visibility is short and the visibility is difficult to secure, resulting in a high traffic accident rate.

In addition, if the color temperature of the lighting is fixed, it is inevitably difficult for the driver to secure visibility not only at night but also when the road visibility is shortened due to weather changes such as fine dust, fog, and rainy weather.
