Background technology

Be provided with elongated electric pole fixing hole, constant-current supply holding tank on the radiator body wall of existing LED street lamp, for the requirement of dispelling the heat, radiating fin also is set in the above, its wall thickness, volume is large, Heavy Weight, need the aluminium of use many, cost is high, and outdoor high-altitude is installed inconvenient, high to the requirement of strength of lamp stand.Because the volume of radiator can not be too large, on it, the diameter of elongated electric pole fixing hole can not be too large, can only reach 30mm, and common lamp stand is for support strength, the lamp stand that general use diameter is 50mm and 60mm, must use the switching metalwork to be connected with the electric pole fixing hole, bring trouble to the installation of lamp stand.The circuit board of constant-current supply and fixed L ED arranges respectively, constant-current supply is arranged in the constant-current supply holding tank of radiator, and constant-current supply is connected by wire with the electric power connection line on the LED circuit plate, and its connection reliability is poor.Radiator adopts the radiator with straight shape fin, and because street lamp uses out of doors, outdoor environment is poor, especially dust is many, and dust drops between the straight wing shape fin of radiator, even if the LED street lamp slightly has the installation of inclination, dust also is difficult for automatically falling, and while raining, a part of dust flows down with rainwater, some has been stayed between fin, be difficult to reach self-cleaning purpose, dust is cumulative, causes the radiating effect of radiator poor, the light decay of LED is large, has reduced the service life of LED street lamp.

The utility model content

The purpose of this utility model solves the above-mentioned problems in the prior art exactly, a kind of solar LED street lamp is provided, the radiator of this solar LED street lamp has greatly increased area of dissipation under the limited volume that takes up room, lightweight, consumptive material is few, cost is low, good heat dissipation effect, the automatically cleaning ability is strong, the light decay of LED is significantly reduced, and lamp stand is installed simple.

For achieving the above object, technical solution of the present utility model is: a kind of solar LED street lamp, and it comprises metal heat sink, one or two LED module, metallic support radiating piece, front apron and the metalized lamp rod installing sleeve be complementary with lamp stand; Each LED module comprises a plurality of great power LEDs, aluminum-based circuit board fixing and that each LED is electrically connected to, fixes and be connected electrically in constant-current supply, reflector peace diffuser on aluminum-based circuit board; Aluminum-based circuit board is fixed on the radiator bottom surface, and reflector covers on LED and goes up and be plugged on aluminum-based circuit board; Flat diffuser covers on outside reflector, and its inner surface is pressed close to reflector, and edge is fixed on the radiator bottom surface by the sealing gasket of crimping; Radiator has cable-through hole on bottom surface, on cable-through hole, blocks up sealing-plug is arranged; The radiator bottom surface is planar sheet, and the above has a plurality of aduncate arc radiating fins, and middle cavity is arranged between radiating fin; Support radiating piece and be connected to radiator middle cavity front portion; The clamping of lamp stand installing sleeve also is fixed on the rear portion of radiator middle cavity; Front apron is fixed on radiator and supports on radiating piece by the sealing gasket of edge crimping; Lamp stand installing sleeve front end is fixed with lower surface and is connected to the sleeve baffle plate on the middle cavity bottom surface, and the sleeve baffle plate also is fixed on the rear end face that supports radiating piece.

Radiator described above, support radiating piece and lamp stand installing sleeve adopt aluminium alloy to make, and there is projection the bottom surface of radiator middle cavity; Supporting the radiating piece upper surface middle is plane, there is the buckling groove A on the projection of being connected to lower surface, two side lower parts have the aduncate arc radiating fin B with the radiating fin marshalling of radiator, and two upper lateral parts have the identical radiating fin A of arc-shaped bend be connected with the radiating fin upper surface of radiator middle cavity both sides; There is clamping lamp stand installing sleeve lower surface is fixed on the buckling groove B on projection, and its lateral support is on the radiating fin of radiator middle cavity both sides.

On the arc-shaped inner surface of the arc radiating fin of radiator described above, have arc concavo-convex, outer surface is smooth flat, and further to increase the area of dissipation of radiator, and outer surface is difficult for pasting dust, easy cleaning.

Decorative shell also is installed on the bottom surface of radiator described above, to increase aesthetics of the present utility model, makes distribution of weight of the present utility model more even, reduce the requirement of strength to lamp stand.When constant-current supply arranges separately, it is arranged on the radiator bottom surface in decorative shell.

The front end of front apron described above is fixed with streamlined decoction cap, to increase the aesthetics of street lamp, reduces windage.

The utility model adopts the LED module form, can design according to the needs of lamp power actual LED module the number, assembling is flexible.The lamp stand installing sleeve is set separately, removed the elongated electric pole fixing hole arranged on the main wall, make the agent structure of radiator only become a thin plate, greatly alleviated the weight and volume of radiator, the lamp stand installing sleeve directly and the diameter of lamp stand be complementary, save the switching metalwork, brought very large convenience to the installation of lamp stand.When radiator, support radiating piece and lamp stand installing sleeve adopt aluminium alloy to make, can drawing and forming, its mechanical strength is high, integral body is thin-wall construction, according to the length intercepting of using, get final product again, greatly reduced the die cost of making each parts, and manufacture craft is simple, cost of manufacture reduces greatly.The arc radiating fin, dust can only be fallen on smooth arc-shaped outer surface, the intrinsic inclined installation angle by street lamp, when rain drop erosion, dust is easy to flow away with rainwater, reaches self-cleaning purpose.

In a word, the utility model assembling is flexible, radiator and support the radiator portion such as radiating piece greatly increased area of dissipation under the limited volume that takes up room, lightweight, consumptive material is few, cost is low, the light decay of good heat dissipation effect, LED significantly reduces, and has self-cleaning ability.
