The specific embodiment
For the ease of clear, understand the technical solution of the utility model, below in conjunction with embodiment, be elaborated.
An embodiment of the present utility model provides a kind of LED street lamp upper cover, as shown in Figure 1, comprises side plate 1 and polylith top board 2; Side plate 1 surrounds a frame; The top of top board 2 covering frames; On side plate 1, be provided with air inlet 3;
Top board 2 comprises the first top board 201 and the second top board 202; The first top board 201 and the second top board 202, on its length direction, the height of its end face reduces to two ends by middle part; The first top board 201 and the second top board 202 tilt to lay along its width interval, and the first adjacent top board 201 is contrary with the incline direction of the second top board 202; The downside of every the first top board 201 aligns and is connected with the downside that is positioned at the second top board 202 of this side, the high side of the first top board 201 is positioned at the below of high side of the second top board 202 of this side, and and forms gas port 4 between the high side of the second top board 202 of this side.
By air inlet 3 is set on side plate 1, and by said structure, at top, form gas port 4, when LED lamp work adstante febre, under the drive of hot-air, can automatically form air-flow, cold air is sucked by air inlet 3, hot-air is discharged by gas outlet 4.In said structure, gas outlet 4 is positioned at peak, therefore in whole process heat flow very unobstructedly, can not form local accumulation.Gas outlet 4 is towards side, and rainwater is difficult for entering thus inside, only can flow to low-lying place along the first top board 201 or the second top board 202 that form gas outlet.And because the apical side height of top board 2 is reduced to two ends by middle part, so rainwater can not deposit on top board 2 yet, and can be rapidly along the length direction of top board 2 to two side flow, and finally by under marginal flow.Therefore the LED street lamp upper cover that, the utility model embodiment provides has the heat radiation feature good with waterproof effect tool.
Preferably, side plate 1 comprises the first side plate 101 of extending along the length direction of top board 2 and the second side plate 102 extending along the width of top board 2; The top of the first side plate 101 is higher than the edge that is positioned at the top board 2 at edge, for stopping the top board 2 that is positioned at edge.The top board 2 that can make to be like this positioned at edge is more firm, difficult drop-off.
While realizing said structure, the connected mode of top board is a lot, for example, according to specified structure and side plate, weld.The present embodiment provides a kind of simple optimal way, and the top of the second side plate 102 exists a plurality of updip edge strips 501 also to exist a plurality of edge strips 502 that have a down dip to support the second top board 202 to support the top of the first top board 201, the second side plates 102; Updip edge strip 501 arranges with edge strip 502 intervals that have a down dip, and the downside of each updip edge strip 501 aligns with the downside that is positioned at the edge strip 502 that has a down dip of this side, and the high side of updip edge strip 501 is lower than the high side of the edge strip 502 that has a down dip of this side.Direct like this top board 2 is ridden on corresponding edge strip and just can form wanted structure, only need afterwards fixing.
For the sidepiece of anti-sealing by gas outlet 4 enters, make this LED street lamp upper cover there is better waterproof effect, preferred, the high side of updip edge strip 501 is positioned at the below of high side of the edge strip 502 that has a down dip of this side.The sidepiece of gas outlet just can be blocked by the second side plate 102 like this.
The shape of top board 2 can have various ways, for example arc.But for the ease of manufacturing and installing, preferably top board 2 is along its length by middle part stepped reduction to two ends.
In order to prevent that dust or stone are blown into air inlet 3 by wind, preferred, air inlet 3 is provided with filter screen.Same, gas outlet 4 also can arrange filter screen.
For anti-sealing is entered by air inlet 3, preferred, air inlet 3 arranges or is provided with above air inlet 3 downward-sloping cover plate 6 down.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
