Description
Technical field
The utility model belongs to lighting field, particularly a kind of LED lamp.
Background technology
The normal lighting field of high-power LED illumination product obtains and popularizes widely in recent years, but improving constantly along with power, and the heat dissipation problem of great power LED becomes increasingly conspicuous, and must pay attention to the design of its radiator structure.The quality of heat dissipation structure of LED lamp is directly connected to the efficiency of light fixture, light decay and service life, in current high-power LED lamp, the electric energy of about 70% can convert heat energy to, the LED chip test AUTHORITATIVE DATA explanation of some brands, the temperature of LED often rises 20 DEG C, light output will reduce about 10%, directly shortens the life-span of light fixture, so will ensure the low temperature of LED and the stable of light source.High-power LED lamp heat radiation mainly utilizes radiator to complete, and radiator comprises pedestal and the fin be distributed on pedestal, when carrying out fansink designs, usually can consider the length of fin.If length is too small, area of dissipation is then little, and length is excessive, and the heat on pedestal can not be passed to fin tip, and the weight of radiator also can increase simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of LED lamp, and it has suitable fin length, to reach optimum radiating effect.
To achieve these goals, the technical solution adopted in the utility model is as follows: LED lamp, comprise LED light source and radiator, described LED light source is arranged on radiator, described radiator comprises matrix and is distributed in the multiple fin on matrix, it is characterized in that, the length of described fin is equal with the thickness of described matrix.
Preferably, the length of described fin is 5-14 centimetre.
Preferably, the length of described fin is 7-10 centimetre.
Preferably, described fin has 12-15.
Preferably, described intrinsic silicon is provided with heat pipe.
Preferably, horizontal grid is provided with between described adjacent fin.
LED lamp of the present utility model, the matrix thickness of its radiator is equal with fin length, the heat on matrix is made can be fully passed to fin tip, make the area of dissipation of fin and its gross weight reach a balance simultaneously, both effective improving radiating effect, ensures that again heatsink weight can not be overweight.Therefore, the utility model, under the prerequisite ensureing heat radiation appearance and size, cost control, after being optimized design to heat radiation, drastically increases the heat dispersion of radiator.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the technical solution of the utility model is described.
As shown in Figure 1, the utility model is a kind of LED lamp, comprises LED light source 10 and radiator, and described LED light source 10 is arranged on radiator, multiple fin 22 that described radiator comprises matrix 21 and is distributed on matrix 21, the length of described fin 22 is equal with the thickness of described matrix 21.LED lamp of the present utility model, matrix 21 thickness of its radiator is equal with fin 22 length, make the heat on matrix 21 fully can be passed to fin 22 tip, make the area of dissipation of fin 22 and its gross weight reach a balance simultaneously, both effective improving radiating effect, ensures that again heatsink weight can not be overweight.Therefore, the utility model, under the prerequisite ensureing heat radiation appearance and size, cost control, after being optimized design to heat radiation, drastically increases the heat dispersion of radiator.
From the experimental analysis of reality, the length of each fin 22 has corresponding LED chip temperature to correspond, when fin 22 highly continuously value time, chip temperature corresponding with it is also continually varying.Related experiment illustrates, when the length of fin 22 changes between 5-8 centimetre, LED chip temperature is fairly obvious with the change of fin 22 length, and radiator shows quite good heat dispersion; And when the length of fin 22 changes between 8-14 centimetre, LED chip temperature is then not obvious with the change of fin 22 length.Therefore, in the fansink designs of reality, the length selection range of described fin 22 can be 5-14 centimetre, and preferably, the length of described fin 22 is 7-10 centimetre.
The temperature of LED chip can reduce rapidly along with the increase of fin 22 quantity, but after the minimum reaching correspondence, start again slow rising, this is because in the structure of radiator, the quantity of each fin 22 has an optimum value, although effectively increase area of dissipation by the quantity increasing fin 22, but but make often to organize the gap smaller between fin 22, hinder the air flowing between fin 22, reduce the efficiency of fin 22 function of environment heat emission towards periphery on the contrary, therefore, in heat spreader structures design, the quantity of described fin 22 gets 12-15 the best.
In addition, in order to further improving heat radiation efficiency, described matrix 21 inside is provided with heat pipe, to increase heat transmission.
Finally, be provided with horizontal grid 23 between described adjacent fin 22, air channel can be formed between fin 22, be conducive to cross-ventilation, promote the effect that heat distributes.
LED lamp of the present utility model, has suitable fin length, to reach optimum radiating effect.
