The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model integral LED street lamp is described in further detail.
Please refer to Fig. 1 to Fig. 4, in the preferred embodiment, integral LED street lamp of the present utility model mainly comprises integrated lamp body 10 and is fixed at least one led light source module 30 on the lamp body 10, electric apparatus chamber lid 50, bonnet 60.
Be formed with electrical equipment cavity and the heat radiation chamber that comprises the radiating module 105 relative with led light source module 30 numbers for fixed power source module (not shown) on the lamp body 10.Concrete, lamp body 10 comprises that one substantially is trapezoidal panel 101 and is basically perpendicular to panel and the first side wall 103 that extends of panel one dorsad from this panel periphery.Panel 101 is divided into two parts, wherein first 1011 is as the base plate of electrical equipment cavity, the surface of second portion 1013 (light direction one side that defines the integral LED street lamp herein is the surface, and light direction one side is the back side dorsad) is recessed to form the host cavity of a led light source module 30.This host cavity bottom is formed with at least two notches 1015 parallel, that run through second portion 1013, in the present embodiment is three.Panel between two adjacent notches 1015 is as being used for fixing the fixed head 1017 of a led light source module.A radiating module 105 is extended at every fixed head 1017 back side all basic vertical one, do not link to each other mutually between each radiating module 105, run through lamp body forward-and-rearward heat dissipation channel thereby the space between notch 1015 and the radiating module 105 forms, improve the radiating efficiency of lamp body.
In the present embodiment, each radiating module 105 includes a slice the first fin 1051 and multi-disc the second fin 1053 that extends from fixed head 1017 back side one.Multi-disc the second fin 1053 is parallel to each other and perpendicular to the first fin 1051.The first fin 1051 two ends link to each other with the first side wall 103.Do not link to each other mutually between the second fin 1053 between two radiating modules.
First 1011 is connected the back side of the part that connects and extends one second sidewall 107 on the panel 101 with second portion.The second sidewall 107, the first side wall 103 and panel second portion 1013 surround a heat radiation chamber.Bonnet 60 is fixed on the lamp body to hide this heat radiation chamber.For guaranteeing the lamp body radiating effect, the top of radiating module 105, also namely the first and second fin 1051,1053 top and bonnet 60 are at least part of closely is affixed, and the position corresponding to notch 1015 is formed with the groove 61 that runs through bonnet on the bonnet 60.
The second sidewall 107, the first side wall 103 and first 1011 surround the electrical equipment cavity for the fixed power source module.Power module is mainly the led light source module for power supply.Electric apparatus chamber lid 50 is rotationally connected with on the lamp body to hide this electrical equipment cavity.Be provided with for induced environment brightness on the electric apparatus chamber lid 50 and open and close the light-controller 70 of integral LED street lamp according to ambient brightness.Light-controller 70 is electrically connected with power module, and it cuts off or connect street lamp power module light-controller input, that have switching function automatically for the height according to environmental light brightness.
Be formed with a lamppost fixing hole 1031 on the first side wall 103, extend the lamppost fixed leg 1033 of a hollow along sidewall one in the electrical equipment cavity of lamppost fixing hole 1031.Have the fixing hole that is communicated with lamppost fixed leg 1033 inside on the panel 101.Lamppost insert lamppost fixed leg 1033 interior after, can lamppost and integral LED street lamp be fixed together by the fixture that passes fixing hole.In the present embodiment, an end of electric apparatus chamber lid 50 is rotationally connected with the top of the part that is formed with lamppost fixing hole 1031 of the first side wall 103 by the folding pivot structure, and the other end is fixed on the lamp body 10 by screw.Be provided with ring-type silica gel between power source cavity lid the 50 and first and second sidewalls 103,107 tops, silica gel also is set to fill between power source cavity lid the 50 and first and second sidewalls 103,107 and the slit between circuit and its cable hole between the circuit of turnover electrical equipment cavity and its cable hole, so that electric apparatus chamber sealed damp-proof, waterproof, the service life of guaranteeing circuit.
Led light source module 30 is fixed on the fixed head 1017.Each led light source module 30 all mainly comprises the circuit board 31 of being close on the fixed head 1017 and the light-passing board 33 that is arranged on the circuit board 31.Circuit board 31 is rectangle substantially, is provided with a plurality of led light sources 311 on it.Light-passing board 33 is rectangle substantially, is formed with lens 331 corresponding to a plurality of and a plurality of led light source 311 on it.Gap filling between lens 331 and the led light source 311 has transparent silica gel, thereby guarantees in the transmittance process of light without light loss.The 3rd sidewall 333 of an annular is extended on light-passing board 33 4 limits towards fixed head 1017 one.And the position corresponding with the 3rd sidewall 333, fixed head 1017 surface is formed with groove 1019.Seal by sealing strip 35 between the periphery of led light source module and the fixed head 1017, and sealing strip 35 is placed in the groove 1019.Be provided with a plurality of fixing holes on light-passing board 33, circuit board 31 and the fixed head 1017, the three is fixed together by screw 37 and silica gel ring for sealing.
The heat that led light source module 30 produces is by lamp body 10 heat radiations.The heat that LED sends is led lamp body 10 by circuit board 31.Because the dual-side of fixed head 1017 and led light source module 30 fixed thereon does not link to each other with other elements and contacts, and therefore forms chute between different led light source modules 30.The radiating module 105 that is decussate texture increases area of dissipation effectively in fixing lamp body space, and above-mentionedly can allow air enter between the fin to chute, thereby improve radiating effect thereby the stack effect that can utilize the hot air rising cold air to replenish produces convection current by air, and can play chute the water of fin inner product or dust etc. are drained.Because lamp body is the moulding of metal integrated die-casting, each structure of whole lamp body can become the heat radiation medium, thereby reduces the extra heat sink material that arranges, and then reduces cost and improve radiating efficiency.
Although description of the present utility model is carried out in conjunction with above specific embodiment,, those skilled in the art that can carry out many replacements, modifications and variations, be apparent according to above-mentioned content.Therefore, all are such substitute, improve and change all is included in the spirit and scope of attached claim.
