Title:
LED STREET LAMP WITH GOOD HEAT RADIATION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2012/100418
Kind Code:
A1
Abstract:
An LED street lamp with good heat radiation function comprises a street lamp main body (1), at least one LED light-emitting module (2), and an LED power supply (3). The street lamp main body (1) includes heat-radiation parts (11) and a connection part (12) connected at one end of the heat-radiation parts (11). The LED power supply (3) is arranged above the connection part (12). Each LED light-emitting module (2) corresponds to an independent heat-radiation part (11). Each heat-radiation part (11) comprises a connection body (111) for fixedly connecting the LED light-emitting module (2), and two crossed main radiation fins (112, 113) which extend to the periphery with the connection body (111) as the center. The heat-radiation part (11) is divided into four fan-shaped regions by the main radiation fins (112, 113). In each of the fan-shaped regions, multiple parallel branches of radiation fins (1141, 1151, 1161, 1171) are distributed, and diverge to the periphery with the connection body (111) as the center. Air passages (1142, 1152, 1162, 1172) are formed between two adjacent branches of radiation fins (1141, 1151, 1161, 1171). The LED street lamp has good heat-radiation effect, long and narrow air passages, and avoids dust accumulation, and is easy to clean even after dust accumulation.
