Background technology

LED (Light Emitting Diode, light emitting diode), it can directly and efficiently convert electrical energy into visible Light, and possess the service life up to tens thousand of hours~100,000 hour, so as to be widely used in landscape, safety, special type and general Field, the market potentials such as logical illumination are beyond measure.

Use LED make LED lamp with it is of fine quality, durable, energy-conservation the advantages that and be referred to as the most frequently used illuminator.So And a drawback existing for LED lamp itself is that LED lamp light efficiency is had a great influence by LED junction temperature, higher chip knot Temperature will cause light efficiency to be decreased obviously, and influence whether the service life of LED lamp.Because LED is when luminous, itself Temperature can be raised constantly, especially high-power LED etc., in lasting illumination work, if heat can not caused by LED Exhale in time, it will cause the damage of LED, influence the service life of LED.Furthermore LED lamp use environment is more Become, dust aggregation and rainwater also can LED overheating failure or short circuits from structural member gap penetration.

Utility model content

The purpose of this utility model purpose be solve problem of the prior art, there is provided LED road lamp shade, by integral into Lamp housing, fin, alar part and the radiating tube of type realize quick heat radiating, and ensure there is good sealing, and supporting installation is dust-proof Lid reduces fin dust accumulation.

The technical solution adopted in the utility model is：

LED road lamp shade, including lamp housing, two pieces of end casings and transparency glass plate and some fin, in the lamp housing two Side is provided with alar part and lamp housing and alar part and forms light trough for LED illuminator installation, the fin be located at lamp housing outer surface and Fin is arranged parallel to each other along the length direction of alar part, and the free end of the alar part offers what is fixed for transparency glass plate Neck, the end casing are fixed on the both ends of light trough and sealing gasket are provided between section lid plate and light trough, the end casing, transparent Glass plate and light trough form a closed cavity, it is characterised in that：Dust cap and dust-proof is provided with the top of the fin Linked together at lid both sides of the edge with the fin at lamp housing both sides of the edge, remaining fin top and dust cap following table There is gap between face, be respectively equipped with the radiating tube of three hollow cylindricals in the lamp housing on both sides of the middle and radiating tube causes in light trough Exterior domain is turned on, and the dust-break pipe of three hollow cylindricals, the radiating tube top are respectively equipped with corresponding dust cap lower surface both sides Portion is inserted into dust-break pipe, has gap between radiating tube top and dust-break tube top end and radiating pipe outer wall and dust-break inside pipe wall.

Further, the lamp housing, fin, alar part and radiating tube are integrally formed, using metal material, such as thermal conductivity Good aluminum alloy materials overall processing forms, and improves overall sealing property and high efficient heat dissipation performance.

Further, the height of some fin gradually reduces from middle part to both sides, and the dust cap is curved, arc Degree is matched with fin height changing value, saves material cost, and LED illuminator is arranged at the medium position of lamp housing, radiating The higher heat that is more conducive to of the height of piece scatters and disappears.

Further, slot is provided with the dust cap both sides of the edge, the fin at lamp housing both sides of the edge is inserted Enter and realize that dust cap is fixedly connected into slot.

Further, screwed hole and the screw for passing through cooperation are offered on the fin in the slot and insertion slot Realization is fastenedly connected.

The beneficial effects of the utility model are：

The utility model is simple in construction, the lamp housing, fin, the wing that heat caused by LED illuminator passes through integrated molding Portion and radiating tube Quick diffusing are gone out, and the purpose for reaching high efficiency and heat radiation also improves overall sealing, prevents rainwater and dust Seepage cause short circuit or the failure phenomenon of LED street lamp.Meanwhile radiating tube is provided with lamp housing, being capable of auxiliary LED illuminator Heat is produced to scatter and disappear.In order to avoid dust accumulation reduces its radiating effect on fin, it is provided with the top of fin dust-proof Cover and have gap, do not influenceing to radiate while serve the effect for reducing dust aggregation.The position of radiating tube is located in the middle part of lamp housing, Dust-break pipe coordinates radiating tube on corresponding dust cap position, and compared to marginal position, air motion is slower, can effectively prevent powder Dirt is entered at LED illuminator by radiating tube, causes LED illuminator overheating failure or short circuit.

Embodiment

In order that the advantages of the purpose of this utility model and technical scheme, is more clearly understood, below in conjunction with accompanying drawing and reality Example, the utility model is further elaborated.

As shown in accompanying drawing 1~6, LED road lamp shade, including 1, two piece of end casing 2 of lamp housing and transparency glass plate 3 and it is some dissipate Backing 4, alar part 5 is provided with the both sides of lamp housing 1 and lamp housing 1 and alar part 5 form the light trough installed for LED illuminator, described Fin 4 is located at the length direction of the outer surface of lamp housing 1 and fin 4 along alar part 5 and is arranged parallel to each other, the freedom of the alar part 5 End offers the neck 6 fixed for transparency glass plate 3, and the end casing 2 is fixed on the both ends of light trough and in section lid plate 2 and lamp Sealing gasket 7 is provided between groove, the end casing 2, transparency glass plate 3 and light trough form a closed cavity.In the radiating The top of piece 4 is provided with dust cap 8 and the both sides of the edge of dust cap 8 and is connected to one with the fin 4 at the both sides of the edge of lamp housing 1 Rise, have gap between remaining top of fin 4 and the lower surface of dust cap 8, be respectively equipped with the on both sides of the middle of lamp housing 1 in three The radiating tube 9 and radiating tube 9 of void column shape cause exterior domain conducting in light trough, are set respectively in the corresponding lower surface both sides of dust cap 8 There is the dust-break pipe 10 of three hollow cylindricals, the top of radiating tube 9 is inserted into dust-break pipe 10, the top of radiating tube 9 and dust-break pipe There is gap between 10 tops and the outer wall of radiating tube 9 and the inwall of dust-break pipe 10.Heat caused by LED illuminator passes through fin 4 And radiating tube 9 is quickly scattered and disappeared, and dust cap 8 and dust-break pipe 10 reduce aggregation of the dust on fin 4, ensure Radiating effect.
