Disclosed a radiating system of an LED threaded spot lamp. The system comprises a case (1), a lamp head case (2), an end cover (3), a mounting seat (4), a slide seat (5), a driving apparatus (6), an LED light source (7), a radiator (8), and an optical lens (10). The case comprises a lower case (101) and an upper case (102), a radiating board is disposed between the lower case and the upper case, and radiating holes are formed in the radiating board. The radiator comprises a front end surface and radiating fins. The radiating fins are disposed on the front end surface. A ventilating groove extending to the left and the right is formed between adjacent radiating fins. Air outlets of the ventilating groove are opposite to the radiating holes. A fan is disposed on the radiator. A light barrier is disposed at the inner side of the radiating board, and a gap is formed between the radiating board and the light barrier. A radiating method of the system is as follows: an LED light source generating heat and transmitting the heat into a radiator, and meanwhile, the fan working, external cold air entering the radiator, performing heat exchange on the cold air in the radiator, the heat air being changed into hot air, and the hot air being radiated from radiating holes. The radiating system can overcome the influences of wind currents on the quality of light spots and improve the utilization rate of light. |
