Abstract
The utility model discloses a double light source via hole radiating LED street lamp, which consists of a perforated grid street lamp housing, LED light sources, light distribution lenses and a driving power supply. The middle part of the perforated grid street lamp housing is provided with two independent heat transfer substrates. A mounting surface on the lower part of each heat transfer substrate is provided with one LED light source. The light distribution lenses are arranged on the periphery of the LED light sources. Radiating fins which are intersected with each other are distributed on the peripheries of the heat transfer substrates. The radiating fins and via holes among the radiating fins form a perforated grid shape. Positive and negative poles of each LED light source in a light source chamber are connected with positive and negative poles of an output end of the driving power supply. The driving power supply is fixedly arranged in a driving power supply chamber. The double light sources and a radiator are arranged independently so as to disperse a heat source. The heat source of the LED light sources is arranged at the center position of the radiator so as to be favorable to conduction and dissipation of heat. The perforated grid radiating structure of the street lamp increases air convection and realizes a more efficient radiating approach. Meanwhile, the perforated structure effectively avoids the critical defect that the upper surface of the common LED street lamp housing is easy to accumulate dust to impede heat dissipation.
