Utility model content
The purpose of this utility model be to provide a kind of can be rainproof, windproof, dustproof and the LED street lamp of good heat dissipation effect.
The technical scheme that realizes the utility model object is: the utlity model has lamp stand and lamp holder; Described lamp holder comprises lamp housing, LED lamp group, power supply changeover device; Described lamp housing comprises upper shell and lower house, and lower house is provided with LED lamp group, and power supply changeover device is arranged on lamp housing inside; Described lamp holder is provided with cooling system, the passage that cooling system comprises air inlet, air outlet, fan and utilizes the inner clearance spaces of lamp housing to form; Described air inlet is arranged on the lower surface of lower house, and air outlet is arranged on lamp housing, and air inlet and air outlet are all and channel connection; Described fan is arranged in LED lamp group and is positioned at lamp housing inside; Described lamp housing inside is provided with air ducting, and air ducting is arranged on air inlet top; Described fan is through water-proofing treatment.
Above-mentioned air ducting is wind deflector, and wind deflector is fixedly installed on lower house; Described wind deflector extends near a side air admission mouth top of LED lamp group from air inlet.
Above-mentioned air ducting is wind scooper, and wind scooper is fixedly installed on lower house; Described wind-guiding cover cap is located on air inlet and the air guide hole of wind scooper does not face toward the direction of LED lamp group.
Above-mentioned lower house is provided with more than one LED lamp group, in each LED lamp group, is equipped with fan.
The air outlet of above-mentioned cooling system is arranged on the lower surface of lower house and is positioned at the both sides of each LED lamp group; The rotation of described fan and the lower surface of lower house intersect.
The air inlet of above-mentioned cooling system is arranged on lower house near one end of lamp stand; Described power supply changeover device is arranged between air ducting and LED lamp group.
Above-mentioned lamp housing is also provided with air outlet away from one end of lamp stand.
The utlity model has positive effect: (1) the utility model is provided with air ducting at air inlet place, and the air guide hole of air ducting does not face toward the direction of LED lamp group, can effectively protect like this fan in LED lamp group not to be subject to the impact of high wind, and there is well rainproof and dustproof effect; (2) the utility model deliberately zooms out the distance between LED lamp group and air inlet, can guarantee that like this hot blast that cooling system is discharged can not be back in lamp holder again; (3) the utility model adopts several LED lamp groups, and the both sides that are equipped with fan and each LED lamp group in each LED lamp group are equipped with air outlet, and while guaranteeing that like this fan in a LED lamp group breaks down, other fans equally can carry out heat radiation work.
