Technical field
The utility model relates to a kind of LED street lamp, refers in particular to a kind of LED energy-conserving road lamp with power supply hermetically-sealed construction.
Background technology
Along with the LED light fixture substitutes traditional bulb gradually as energy-saving lamp, the light fixture of road lighting also is widely used the LED lamp.The power supply of existing LED street lamp is generally external, and connecting line is exposed, and affects the life-span of light fixture.
The utility model content
The purpose of this utility model is to provide a kind of LED energy-conserving road lamp, and it has the power supply hermetically-sealed construction, makes on-chip power, improves water-tight.
For achieving the above object, the utility model is by the following technical solutions:
A kind of LED energy-conserving road lamp, it comprises lamp body and coupled power supply hermetically-sealed construction, this power supply hermetically-sealed construction comprises that power pack, supply unit, power supply wiring reach the locking part that is connected that is connected with the power supply box body, described power pack comprises upper box cover and the lower casing of mutual snap close, described upper box cover is provided with connecting hole and coupling head, described supply unit is positioned at power pack, outside civil power is by described coupling head access power pack, and described power supply wiring passes connecting hole and is connected with power pack lamp body outward.
Further, be provided with the accommodating box group that some surroundings are separated in described upper box cover, described accommodating box group comprises for the first storage tank that supply unit is installed and is positioned at the second storage tank of power pack end position.
Be provided with the sealing ring corresponding with the first storage tank position in described lower casing.
Described upper box cover is connected the arc notch of installing for connecting locking part with the lower casing end.
Described connection locking part is T-shape, comprises affixed hollow cross bar and montant, and described cross bar holding is fastened in the second storage tank, and described montant passes described arc notch and is communicated to the power pack outside.
After adopting technique scheme, the utility model is compared with existing background technology, have following advantage: power supply wiring all is placed in power pack or lamp body, power pack adopts upper and lower covers to add the sealing ring structure, outside civil power accesses power pack by coupling head, and power supply output seals the access lamp plate by connecting hole, can prevent dust, waterproof, sun-proof and avoid extraneous all-environment impact, improve power supply service life.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also shown in Figure 1ly, this is novel discloses a kind of LED energy-conserving road lamp, and it comprises lamp body 60 and power supply hermetically-sealed construction, wherein:
The power supply hermetically-sealed construction is connected with the lamp body 60 of street lamp, it comprise power pack, supply unit 30, power supply wiring 40 and be connected with the power supply box body be connected locking part 50.Power pack comprises upper box cover 10 and the lower casing 20 of mutual snap close.
Fig. 2 opens the structural representation of lower casing 20 for the structure of Fig. 1 is turned over to the back side: be provided with connecting hole 11 and coupling head 12 in upper box cover 10, supply unit 30 is positioned at power pack.
Be provided with the accommodating box group that some surroundings are separated in upper box cover 10, the accommodating box group comprises for the first storage tank 13 that supply unit 30 is installed and is positioned at the second storage tank 14 of power pack end position.Lower casing 20 is provided with the sealing ring 21 corresponding with the first storage tank 13 positions.
Upper box cover 10 is connected the end and is provided with the arc notch 22 of installing for connecting locking part 50 with lower casing.Connecting locking part 50 is T-shape, comprises affixed cross bar 51 and montant 52, and cross bar 51 and montant 52 are hollow structure, are convenient to the layout of power supply wiring 40.Cross bar 51 holdings are fastened in the second storage tank 14, and montant 52 passes arc notch 22 and is communicated to the power pack outside.
During use, open lower casing 20, supply unit 30 is arranged on the first storage tank 13 interior fixing, it is interior fixing that connection locking part 50 is arranged on the second storage tank 14, outside civil power is by coupling head 12 access power packs, and power supply wiring 40 passes connecting hole 11 and is connected with the outer lamp body 60 of power pack.After installing supply unit 30, connecting hole 11 is used sealant sealing.Close lower casing 20, get final product with upper box cover 10 snap closes.Because lower casing 20 is provided with the sealing ring 21 corresponding with the first storage tank 13 positions, when upper and lower Hasp lock is buckled well, sealing ring 21 is the first storage tank 13 surroundings sealings, can prevent dust, waterproof, sun-proof and avoid extraneous all-environment impact, improves power supply service life.
The above; it is only the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement are within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
