Description

A kind of LED street lamp ballast casing of being convenient to heat radiation

Technical field

The utility model relates to a kind of ballast casing of outdoor formula street lamp.

Background technology

Street lamp on now a lot of road surfaces adopts ballast, but this for problem of the ballast ubiquity on street lamp: to dispel the heat bad, because can be hot after street lamp works long hours, not street lamp only itself, ballast itself also can generate heat, and in view of street lamp work long hours after easily heating, so it is metal material that ballast casing all adopts, the thermal conductivity of metal is good, once radiating effect is bad, whole ballast casing temperature all can Continued, so heat radiation is very crucial for ballast.

Utility model content

The utility model technical issues that need to address are, a kind of LED street lamp ballast casing of being convenient to heat radiation is provided, and have solved the not good problem of ballast radiating effect on LED street lamp.

The technical solution of the utility model is: a kind of LED street lamp ballast casing of being convenient to heat radiation, comprise base, upper cover and be fixed on base and two side covers of upper cover side, it is characterized in that: the side of described base is respectively equipped with ground floor bending part and second layer bending part in lateral, the bottom laminating of described upper cover is positioned at ground floor bending part, between described upper cover medial surface and second layer bending part, be provided with cooling pipe, upper cover side is provided with air outlet and is communicated with described cooling pipe, described side cover medial surface is provided with air inlet and is communicated with described cooling pipe.

Preferably, described side cover medial surface is provided with plenum chamber in air inlet position, is provided with air inlet passage between plenum chamber and cooling pipe.

Preferably, in described plenum chamber, fan is installed.

Preferably, described second layer bending part is provided with the radiating groove of paliform.

Preferably, described cooling pipe is made up of side by side 2 above S bend pipe roads.

Adopt after the technical program, upper cover inner side at ballast is provided with a cooling pipe for dispelling the heat, this cooling pipe is by air inlet air intake, the flow through side of whole upper cover of cold wind, then flow out from air outlet, so just utilize natural wind-force to lower the temperature to the shell of ballast, good heat dissipation effect, and energy-conserving and environment-protective.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:

As shown in Figures 1 to 6, a kind of improvement structure of ballast casing, comprise base 1, upper cover 2 and be fixed on base and two side covers 3 of upper cover side, when installation, base is at bottommost, upper cover covers base from base top, upper cover the upper left corner and the upper right corner have two hole 23(that tighten up a screw to see Fig. 6), the lower left corner of base and the lower right corner have two lower screw hole 14(to see Fig. 5), side cover 3 is provided with the through hole 35 mating with screw hole, by upper, lower four screw holes are fixed on the front and back sides of upper cover and base, be beneficial to more very much the dismounting of ballast by the mode of fastened by screw, the cross section of described side cover is L-type, be divided into vertical plane and plane, the plane of L-type is provided with mounting hole site 34, the side of described base 1 is respectively equipped with ground floor bending part 11 and second layer bending part 12 in lateral, ground floor bending part and second layer bending part are to be all L-type bending, described upper cover cross section is U-shaped, just fit and be positioned at ground floor bending part 11 in two U-shaped flank bottoms, so bending part has just been realized the limit function of the position, left and right to upper cover for the first time, between described base ground floor bending part and base, be provided with circuit board fixing groove 13, the circuit board of ballast can be embedded in circuit board fixing groove to 13 by circuit board fixing groove 13, simple in structure, effect is remarkable, side cover 3 is also having wire serial ports 33 to pass and be connected to circuit board for wire simultaneously, be positioned on the vertical plane of L-type, the bending of second layer bending part 12 is mainly in order to form a new clearance space between upper cover medial surface and base side, in this clearance space, namely between described upper cover medial surface and second layer bending part, be provided with cooling pipe 4, upper cover side is provided with air outlet 21 and is communicated with described cooling pipe 4, one of them side cover 3 medial surface is provided with air inlet 31 and is communicated with described cooling pipe, the upper cover side that can contact cooling pipe when cold wind process cooling pipe cools, simultaneously can be to the base side of opposite side, be that second layer bending part also has the effect that necessarily cools, because ballast material now is on the market substantially all metal, metal has good thermal conductivity, so second layer bending part 12 is in being cooled, cooling effect can be extended into whole base, preferably, described second layer bending part is provided with the radiating groove 121 of paliform, radiating groove 121 is conducive to the circulation of air of the second bending part inner side to the cooling pipe place in outside, realize convection current, contribute to inner air to cool, described upper cover side and upper surface are provided with heat radiation male and fomale(M&F) 22, and heat radiation male and fomale(M&F) 22 has increased the surface area of upper cover 2, has further strengthened radiating effect in conjunction with the cooling pipe of medial surface.

The schematic diagram of ballast inside as shown in Figure 4, preferably, cooling pipe described in this example is preferably made up of side by side 2 above S bend pipe roads, cooling pipe 4 fore-and-aft directions run through the side of whole upper cover, and the cooling pipe area coverage of flexure type is larger, when cooling, maximum magnitude has covered whole upper cover side, makes cooling heat dissipation effect reach best, in order further to strengthen the cooling heat dissipation of ballast inside, be provided with plenum chamber 32 at described side cover medial surface in air inlet position, between plenum chamber 32 and cooling pipe 4, be provided with air inlet passage 41, extraneous cold wind enters plenum chamber from air inlet, then be diverted to two cooling pipes on upper cover side by plenum chamber, can be chosen in simultaneously and in plenum chamber, install a fan additional, the power supply source of fan can be public with street lamp, because street lamp is to open according to the time substantially, when street lamp is idle, itself does not also start fan, in the time that street lamp is worked, fan also starts thereupon, can not produce unnecessary energy loss.

When ballast work, fan is opened, cold wind enters from the air inlet 31 of side cover 3, enter into plenum chamber 32, air is shunted in plenum chamber, flows into two cooling pipes 4 by air inlet passage 41, the flow through side of whole upper cover 2 of cooling pipe, and the air outlet 21 covering from above flows out, complete cooling.

Below only with regard to the utility model preferably example be described, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above example, its concrete structure allows to change, those skilled in the art can make various changes and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
