Abstract

The invention discloses a high-efficiency heat dissipating street lamp. The high-efficiency heat dissipating street lamp comprises a lamp pole, a heat dissipating device which is directly or indirectly fixed on the lamp pole and a plurality of light-emitting diode (LED) light sources which are fixed on the heat dissipating device. The heat dissipating device comprises a metal vent pipe, and an LED light source installation area and a heat dissipating fin installation area are arranged on the peripheral surface of the vent pipe. A plurality of heat dissipating fins are fixed on the heat dissipating fin installation area, and a plurality of through holes which penetrate through the pipe wall of the vent pipe are arranged in the vent pipe. An induced air passage is arranged in the lamp pole, and one end of the induced air passage is communicated with one end of the vent pipe. A plurality of air holes which penetrate through the lamp pole are arranged in the induced air passage, and the air holes are arranged below the heat dissipating device. An induced draft fan is arranged in the induced air passage, and a temperature controlled switch which is used for controlling the induced draft fan is arranged in the heat dissipating device. According to the high-efficiency heat dissipating street lamp, the number of the installed LED light sources in a unit area on the heat dissipating device is increased under the condition that the size of the heat dissipating device is not enlarged. A cooling effect is improved along with the increase of quantity of heat produced by the LED light sources, and the high-efficiency heat dissipating street lamp is reasonable in design and low in cost, thereby being a better choice for energy conservation remolding of street lighting.

Description

technical field [0001] The invention relates to a street lamp, in particular to an efficient heat dissipation LED street lamp. Background technique [0002] In the field of street lamps, LED street lamps (Light Emitting Diodes, light-emitting diodes), that is, semiconductor lighting lamps, are high-efficiency solid-state light sources that can emit light with weak electric energy based on semiconductor PN junctions. And under the injection current, the holes injected into the P region and the electrons injected into the N region diffuse to the active region and emit photons through radiative recombination, which directly converts electrical energy into light energy. It is a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. [0003] Following the proposal of "energy saving and emission reduction" and "low carbon", many domestic and foreign enterprises and res...
