Abstract
The utility model discloses a light-emitting diode (LED) street lamp radiating plate which comprises a base plate and a plurality of radiating fins arranged on the base plate. The base plate is bending-shaped, and the upper end of the base plate protrudingly extends to form a connection portion of a circular structure. The radiating fins are arranged at the upper end of the base plate and on the connection portion, the lateral wall of each radiating fin is corrugate, and a clamping portion is arranged at the lower end of the base plate. The radiating area is enlarged due to the radiating fins with the corrugate lateral walls, and accordingly the radiating effect of the radiating plate is greatly improved. In addition, the radiating plate is simple in structure and convenient to install.
Description
Technical field
The utility model relates to a kind of heat abstractor, relates in particular to a kind of fin of the LED of being applicable to street lamp.
Background technology
Along with the development of LED technology, high light efficiency, low light attenuation, high-power LED have been widely used in many lighting devices such as street lamp, bulkhead lamp capable, Tunnel Lamp, shot-light, stage lighting, fluorescent lamp.But the LED lamp in use can produce a large amount of heats, as can not be in time these heats being got rid of, can make the LED lamp overheated and then make other electronic components of LED lamp impaired, reduces the service life of LED lamp.
Take the LED street lamp as example, it relies on energy-conservation, produce the life-span, advantages such as maintenance cost is low and being used widely, many LED street lamps all adopt the design of Modular lamp bar, and lamp bar fin all adopts aluminium section bar to process, have light, the advantage such as reliable, at present, common LED street lamp radiation fins mainly comprises the baseplate part of fixed L ED lamp and is arranged at the radiating fin that is used for heat radiation on the baseplate part, radiating fin vertically is arranged on the baseplate part, and equidistant between each radiating fin, but be subject to the not smooth of the volume of LED street lamp and inner air thereof circulation, radiating effect is not good.
Therefore, be necessary to provide a kind of simple in structure, good heat dissipation effect and fin easy for installation to solve the deficiencies in the prior art.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, good heat dissipation effect and LED street lamp radiation fins easy for installation.
For achieving the above object, the technical solution of the utility model is: a kind of LED street lamp radiation fins is provided, it comprises substrate and is arranged at some radiating fins on the described substrate, wherein, described substrate is bending, and the upper end of described substrate protrudes out the connecting portion of a rounded structure, and described radiating fin is arranged on the upper end and described connecting portion of described substrate, and the sidewall of each described radiating fin all is corrugated, and the lower end of described substrate is provided with the holding section.
Preferably, described substrate comprises a base portion, the two ends of described base portion upwards are bent to form the first kink, the end of two described the first kinks is bent to form the second kink downwards, the end of two described the second kinks is provided with described holding section, and the upper end of described base portion outwards protrudes out and forms described connecting portion.
Preferably, offer circular hole on the described connecting portion.
Preferably, offer slot on the described holding section.
Compared with prior art, because LED street lamp radiation fins of the present utility model, it comprises substrate and is arranged at some radiating fins on the described substrate, wherein, described substrate is bending, and the upper end of described substrate protrudes out the connecting portion of a rounded structure, and described radiating fin is arranged on the upper end and described connecting portion of described substrate, and the sidewall of each described radiating fin all is corrugated, and the lower end of described substrate is provided with the holding section; Radiating fin with corrugated sidewall has increased area of dissipation, significantly improves the radiating effect of fin, and this fin is simple in structure, easy for installation.
Description of drawings
Fig. 1 is the structural representation of the utility model LED street lamp radiation fins.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, similar element numbers represents similar element in the accompanying drawing.Fin 1 provided by the utility model is applicable to the LED street lamp, its good heat dissipation effect, and easy for installation.
Such as Fig. 1, shown in Figure 2, LED street lamp radiation fins 1 provided by the utility model, comprise substrate 10, connecting portion 20 and some radiating fins 30, wherein, described substrate 10 is bending, and the upper end of described substrate 10 protrudes out the connecting portion 20 of rounded structure, some described radiating fins 30 are arranged on the upper end and described connecting portion 20 of described substrate 10, the free end of described radiating fin 30 is positioned on the same circumference, therefore, the length of each radiating fin 30 is unequal, and the sidewall of each described radiating fin 30 all is corrugated, and the lower end of described substrate 10 also is provided with holding section 14.
Continuation is in conjunction with Fig. 1, shown in Figure 2, described substrate 10 comprises a base portion 11, the two ends of described base portion 11 upwards are bent to form the first kink 12, the end of two described the first kinks 12 is bent to form the second kink 13 downwards, namely two second kinks 13 are the both sides that " eight " word shape is arranged at base portion 11, and the end of two described the second kinks 13 is provided with described holding section 14.Particularly, described holding section 14 is bent to form to the direction of base portion 11 after by the bending downwards of the end of the second kink 13 again, therefore, be formed with a slot 141 on the holding section 14, described slot 141 is used for being connected with lampshade, between described lampshade and the substrate 10 the LED luminescence component is installed then.The upper end of described base portion 11 then outwards protrudes out and forms described connecting portion 20, also offer circular hole 21 on the connecting portion 20, described radiating fin 30 is connected in the sidewall of described connecting portion 20 and the upper side wall of substrate 10, under the prerequisite that keeps formed objects, described radiating fin 30 is undulatory sidewall and has strengthened contact-making surface with air, significantly improves radiating effect.
Because LED street lamp radiation fins 1 of the present utility model, it comprises substrate 10 and is arranged at some radiating fins 30 on the described substrate 10, wherein, described substrate 10 is bending, and the upper end of described substrate 10 protrudes out the connecting portion 20 of a rounded structure, described radiating fin 30 is arranged on the upper end and described connecting portion 20 of described substrate 10, and the lower end of described substrate 10 is provided with holding section 14, and the sidewall of each described radiating fin 30 all is corrugated; Radiating fin 30 with corrugated sidewall has increased area of dissipation, significantly improves the radiating effect of fin 1, and it is simple in structure, easy for installation.
