<p>In an LED lighting system which includes a substrate; an LED frame which is combined to a substrate, has a storage space for receiving an LED chip, and has an open front side; and a lens which is formed on the front side of the LED frame, the LED lighting system includes: an UHF generator which is formed in the storage space and generates ultrahigh frequency (UHF) in the storage space; a temperature/humidity sensor which is formed in the storage space and detects the temperature and humidity of the storage space; and a control part which is connected to the UHF generator and the temperature/humidity sensor, respectively, and controls the on-off of the UHF generator according to the temperature information and the humidity information of the storage space received from the temperature/humidity sensor. Therefore, it can effectively remove humidity according to the internal condition of a lamp through the UHF generator and the humidity sensor. the reliability of products can be improved and also lifespan can be extended.</p> |
