It relates to a solar street light controller equipped with a dimming function and a broadcasting function that can be controlled in a control room and is convenient for maintenance and repair.

In general, with the exponential growth of LED lighting, various integrated circuit devices that supply regulated power to LEDs are appearing one after another, and DC current sources with high power consumption have been used as the standard for a long time, but energy problems are serious. Recently, it has been replaced by a switching mode LED driver, which has emerged as an issue.

Currently, precise control of constant current is required in a wide range of fields from flashlights to electronic signboards in stadiums, and in most cases, a function that adjusts the LED output intensity every moment, that is, a dimming control function is required.

Recently, street lights and security lights are being changed to LED lights, and the LED lights used for street lights and security lights are characterized in that their power consumption varies from 180 to 240 W depending on the supply voltage state.

If the failure of LED lighting to be used with the set rated power is repeated over a long period of time, it may affect the lifespan of the LED lighting. Therefore, it is essential to have a dimming control that can supply precise and rated power to street lights and security lights.

However, since most of the currently developed dimming control of LED lights is for controlling the illuminance of LED lights based on the illuminance received from the illuminance sensor, there are many malfunctions due to dust around the illuminance sensor as well as the brightness of the entire street lamp due to the malfunction. The disadvantage is that it is not uniform.

And, even if there are people on the streetlights, the situation is getting deeper and deeper, because people who are tired of Corona are living in a gloomy life because they do not work.
