In the heat abstractor of this street lamp; illuminator in each illuminating module is equipped with fin separately; effective improving heat radiation efficiency; offer bar shaped passage in housing both sides simultaneously; make to form convection channel in housing, the heat contributing to fin to distribute is discharged outside housing, simultaneously because passage is arranged at housing sidepiece with air; can prevent rainwater from entering, play the effect of protection street lamp.
In the heat abstractor of above-mentioned street lamp, described fin comprises main heat sink and several are distributed in radiating fin on main heat sink, and described main heat sink fits in the lamp plate back side, and described radiating fin is vertical with main heat sink to be arranged.
In the heat abstractor of above-mentioned street lamp, described main heat sink and radiating fin adopt aluminum alloy materials to make.It is low that aluminum alloy materials has cost, and quality is light, the advantage that radiating efficiency is high.
In the heat abstractor of above-mentioned street lamp, described top blind flange is curved.Top blind flange arranges curved, and effectively can prevent the accumulation forming the foreign matter such as dust stratification or birds droppings in cover top portion, affect the heat radiation of shell, meanwhile, the dust stratification in top blind flange or birds droppings etc. also can wash away by rainwater.
In the heat abstractor of above-mentioned street lamp, described housing is divided into power source cavity and emitting cavity by a dividing plate, and described driving power is arranged in power source cavity, and described illuminator and fin are arranged in emitting cavity.By emitting cavity and power source cavity effectively being separated, the security of street lamp can be promoted further, power source cavity carry out sealing prevents electric leakage, emitting cavity only for luminescence, without danger of hazardous electrical discharges.
In the heat abstractor of above-mentioned street lamp, described power source cavity is provided with power supply lid, described power supply lid is articulated with on housing, O-ring seal is provided with between described housing and power supply lid, the other end of described power supply lid is provided with a fastening plate, be provided with controller, driver and connector in described power source cavity, described dividing plate offers through wires hole, in described emitting cavity, be provided with deconcentrator.
Compared with prior art, the heat abstractor of this street lamp by arranging fin separately in illuminating module, improve the radiating efficiency of illuminating module, housing sidepiece arranges passage and forms cross-ventilation and take away heat in housing, in addition, power source cavity and emitting cavity are separated, effectively improves the security of street lamp.
