The realization of the utility model purpose, functional characteristics and advantage, in connection with embodiment, are described further with reference to accompanying drawing.
The specific embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Referring to figs. 1 through Fig. 2, one embodiment of a kind of LED street lamp of the present utility model is proposed, be fixedly connected with successively from the bottom to top base, lamp stand, lamp body, lamp body comprises the cap part 101 that is connected with lamp stand, be fixedly arranged on cap part 101 front ends and be built-in with the LED light source assembly the Lights section 102, be placed in cap part 101 and the drive unit be electrically connected to the Lights section 102.
The LED light source assembly comprises the circuit board be located in the Lights section 102, be located on circuit board and some LED light sources of being electrically connected to drive unit, be sheathed on the leaded light cup 104 on LED light source, also comprises and covers at leaded light cup 104 light transmission piece outward.The quantity of leaded light cup 104 is set to 1, and the scope that arranges of the power of LED light source is 60W to 80W.
Lamp body also comprises the radiator structure that is laid in cap part 101 and the Lights section 102 peripheries, and radiator structure is set to the form diamond checks radiator-grid of Gong the circulation of air of hollow out.Radiator structure comprises the heat-dissipating frame 201 that is located in cap part 101 and the Lights section 102 peripheries, be set up in heat-dissipating frame 201 in parallel to each other and part is fixedly arranged on some the first heat sink strips 202 on cap part 101 and the Lights section 102 upper surfaces, is extended outwardly to second heat sink strip 203, the second heat sink strips 203 at heat-dissipating frame 201 places and the form diamond checks radiator-grid of the interlaced formation hollow out of the first heat sink strip 202 by the sidewall of cap part 101 and the Lights section 102.Wherein, heat-dissipating frame 201, the first heat sink strip 202, the second heat sink strip 203 are made by Heat Conduction Material.Radiator structure surrounds the Lights section 102 and cap part 101, and radiator structure is designed to the radiator-grid of hollow out, make extraneous air can shuttle back and forth fully in whole radiator structure, can circulate in fully the Lights section 102 and cap part 101 peripheries simultaneously, the air that the part heat that the Lights section 102 and cap part 101 produce can directly be circulated is taken away, because radiator structure is made by Heat Conduction Material, another part heat that the Lights section 102 and cap part 101 produce can promptly be delivered on radiator structure in time, heat on radiator structure can promptly be transferred to outside by ventilating air, radiating efficiency is very high, can in time the transfer of heat of LED light source and drive unit generation be gone out, effectively extended the service life of LED light source and drive unit.In addition, the area opened when radiator structure is larger, and the area contacted with extraneous air is larger, and radiating effect is also just more remarkable.
Radiator structure is set to the radiator-grid of hollow out; except making air can fully circulate; also there is the effect that prevents that dust storm, rainwater from gathering; when the dust storm rainwater gathers; easily cause radiating effect poor; ponding infiltrates the Lights section 102 and the interior lamp body that easily causes of cap part 101 produces fault, and the setting of radiator structure of the present utility model can effectively avoid above-mentioned situation to occur, and lamp body has been played to certain protective effect.And radiator structure is set to the radiator-grid of hollow out, the water chestnut lattice that the light that LED light source produces can see through hollow out irradiate upward, and illuminating area is larger, and light utilization is high.In addition, radiator structure is set to the radiator-grid of hollow out, can also save material, can not cause the wasting of resources, effectively reduces production cost.
Heat-dissipating frame 201 in radiator structure is set to fairshaped shape to reduce windage, in the present embodiment, heat-dissipating frame 201 is set to the shape of racket, the form diamond checks radiator-grid that coordinates the hollow out of upper the second heat sink strip 203 and the first heat sink strip 202 interlaced formation, just present the shape that is similar to tennis racket, racket, such racket shape windage is less.The first heat sink strip 202 can vertically arrange or horizontally set, and concrete direction can be set according to actual conditions.The shape of the second heat sink strip 203 is set to straight line or arc curve.Whole radiator structure presents fairshaped design, and except effective reduction windage, appearance is also very attractive in appearance, rich dynamic.
The quantity difference of LED light source and power difference, the design of corresponding radiator structure is also different, as also different as the design that the quantity of size, the first heat sink strip 202 and second heat sink strip 203 of heat-dissipating frame 201 arranges etc.When power is larger, can be by the suitable lengthening broadening of heat-dissipating frame 201, the quantity that simultaneously increases the first heat sink strip 202 and the second heat sink strip 203 makes the form diamond checks radiator-grid, and more crypto set is a bit, like this, the contact area of radiator structure and extraneous air is larger, accelerates radiating efficiency, the radiating effect ideal.In the present embodiment, the scope of the power of LED light source is 60W to 80W, the size of heat-dissipating frame 201 suitably just can, do not need lengthening broadening, the form diamond checks radiator-grid that the first heat sink strip 202 and the second heat sink strip 203 form simultaneously can arrange relatively more sparsely, so can meet the radiating requirements of LED light source in the present embodiment, excellent in heat dissipation effect, simultaneously, the radiator structure of design is saved material like this, can not cause the wasting of resources, and production and processing is convenient, effectively reduces production cost.
The utility model LED street lamp is laid with radiator structure at cap part 101 and the Lights section 102 peripheries, and radiator structure is set to the form diamond checks radiator-grid of Gong the circulation of air of hollow out.The heat that the Lights section 102 and cap part 101 produce can promptly be delivered on radiator structure in time, heat on radiator structure can promptly be transferred to outside by ventilating air, radiating efficiency is high, effectively extended the service life of LED light source and drive unit, the area opened when radiator structure is larger, the area contacted with extraneous air is larger, and radiating effect is also just more remarkable.Simultaneously, the design of radiator structure hollow out radiator-grid has the effect that prevents that dust storm, rainwater from gathering, and the light that makes LED light source produce can irradiate upward through the water chestnut lattice of hollow out, illuminating area is larger, light utilization is high, in addition, can also save material, can not cause the wasting of resources, effectively reduce production cost.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
