Detailed description of the invention
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 the LED street lamp of a kind of good heat dissipation effect 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 LED light source assembly the Lights section 102, be placed in cap part 101 and the drive unit being electrically connected with the Lights section 102.
LED light source assembly comprises the circuit board be located in the Lights section 102, be located at some LED light sources of being electrically connected on circuit board and with drive unit, be sheathed on the leaded light cup 104 on LED light source, also comprises the light transmission piece covering at outside leaded light cup 104.The quantity of leaded light cup 104 is set to 3, and the scope that arranges of the power of LED light source is 150W to 180W.
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 and is located in the heat-dissipating frame 201 of cap part 101 and the Lights section 102 peripheries, is 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 two side of cap part 101 and the Lights section 102.Heat-dissipating frame 201, the first heat sink strip 202, the second heat sink strip 203 are made by Heat Conduction Material.Wherein, the quantity of the first heat sink strip 202 is set to 18 to 25, and the sum of the second heat sink strip 203 quantity that the two side of cap part 101 and the Lights section 102 extends outwardly is set to 10 to 16.
Radiator structure surrounds the Lights section 102 and cap part 101, and radiator structure is designed to the radiator-grid of hollow out, extraneous air can be shuttled 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 extend the service life of LED light source and drive unit.In addition, the area opening when radiator structure is larger, and the area contacting 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; in the time that 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, coordinate the form diamond checks radiator-grid of 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 longitudinally 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 in the design that the quantity of the size of heat-dissipating frame 201, the first heat sink strip 202 and the second heat sink strip 203 arranges etc.In the time that power is larger, can be by suitable heat-dissipating frame 201 lengthening broadening, the quantity that simultaneously increases the first heat sink strip 202 and the second heat sink strip 203 makes 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, radiating effect ideal.In the present embodiment, the scope of the power of LED light source is 150W to 180W, power is relatively large, like this, heat-dissipating frame 201 is lengthening broadening suitably, the quantity of the first heat sink strip 202 and the second heat sink strip 203 can suitably increase simultaneously, as the quantity of the first heat sink strip 202 is set to 18 to 25, the sum of the quantity of the second heat sink strip 203 is set to 10 to 16, more crypto set is a bit can to make like this form diamond checks radiator-grid, effectively increase the contact area of radiator structure and extraneous air, accelerated radiating efficiency, radiating effect ideal.
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 extend the service life of LED light source and drive unit, the area opening when radiator structure is larger, the area contacting 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 LED light source produces can be irradiated through the water chestnut lattice of hollow out upward, 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 description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
