Description
Technical field
The utility model relates to LED field, is specifically related to a kind of LED lamp heat sink.
Background technology
Along with the development of social production, the fast development of light fixture, a large amount of LED is produced, use, in order to ensure the normal use of LED, normal lighting and in producing the effect of LED lamp heat sink be very important, application number is that CN201210445186.2 discloses a kind of LED lamp heat sink, comprise radiator body, described radiator body is primarily of fin and newel composition, described fin is fixed on described newel outer surface with radial uniformly, described newel inside is a cavity, its lower end connects LED mounting seat, structure is simple, corrosion-resistant and good heat dissipation effect, but this radiator does not adopt copper sheet heat conduction, thermal conductance output capacity is poor, heat exchange between fin is little, optimum radiating effect can not be reached.
Utility model content
The purpose of this utility model is to provide a kind of LED lamp heat sink, to solve the above-mentioned multinomial defect caused in prior art.
The technical problem that the utility model solves can realize by the following technical solutions: a kind of LED lamp heat sink, comprise radiator body, described radiator body bottom is connected with LED mounting base, described radiator body is provided with heat abstractor, described heat abstractor is connected with radiator body by copper sheet, described heat abstractor is made up of some fin, the gap of 2-3mm is left between described fin, the size of described fin far and gradually increases along with apart from radiator, and described fin is provided with stub.
Preferably, described fin is relative between two, and on relative two sides, the fin one side of described lower floor arranges fixture, and the upper correspondence position of fin one side on described upper strata arranges groove, and two fin grafting are connected.
Preferably, described fin is trapezoidal.
Preferably, described fin is at least 3.
Preferably, described fin is magnadure.
The utility model has the advantage of: adopt copper sheet heat conduction, strengthen thermal conductance output capacity, the ascending setting of fin, make the heat exchange between fin more remarkable, the setting of stub makes radiating effect more obvious, reduce the light decay of LED, extend the service life of LED, trapezoidal fin area of dissipation is maximum, being at least 3 fin makes heat exchange more easily carry out, magnadure is hard, not fragile, is suitable for using in the utility model.

Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As depicted in figs. 1 and 2, a kind of LED lamp heat sink described in the utility model, comprise radiator body 1, described radiator body 1 bottom is connected with LED mounting base 2, described radiator body 1 is provided with heat abstractor 3, described heat abstractor 3 is connected with radiator body 1 by copper sheet 4, described heat abstractor 3 is made up of some fin 5, the gap of 2-3mm is left between described fin 5, described fin 5 becomes large gradually to away from radiator body 1 direction, described fin 5 is provided with stub 6, adopt copper sheet heat conduction, strengthen thermal conductance output capacity, the ascending setting of fin, make the heat exchange between fin more remarkable, the setting of stub makes radiating effect more obvious, reduce the light decay of LED, extend the service life of LED.
It should be noted that, described heat abstractor 3 is highly 8-10cm, described fin 5 is trapezoidal, trapezoidal fin area of dissipation is maximum, and described fin 5 is at least 3, is at least 3 fin and heat exchange is more easily carried out, described fin 5 is magnadure, magnadure is hard, not fragile, is suitable for using in the utility model.
Described fin 5 is relative between two, and on relative two sides, fin 5 one side of described lower floor arranges fixture 8, and the upper correspondence position of fin 5 one side on described upper strata arranges groove 7, and the grafting of two fin 5 is connected.
In addition, the quantity of described fin 5 suitably can increase in rational scope, and described copper sheet 4 answers running check, prevents from burning out and affecting heat dispersion.
Based on above-mentioned, adopt copper sheet heat conduction, strengthen thermal conductance output capacity, the ascending setting of fin, make the heat exchange between fin more remarkable, the setting at 70 ° of angles makes radiating effect more obvious, reduces the light decay of LED, extends the service life of LED, trapezoidal fin area of dissipation is maximum, being at least 3 fin makes heat exchange more easily carry out, and the aluminum alloy material capacity of heat transmission is strong, is suitable for using in the utility model.
More than show and describe the general principle of utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; description in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements are all within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
