Description

A kind of heat dissipation device of LED lamp of Homogeneouslly-radiating
Technical field
The invention belongs to radiator field, in particular it relates to the heat dissipation device of LED lamp of a kind of Homogeneouslly-radiating.
Background technology
Along with the development of science and technology, LED relies on the high and low power consumption of luminous efficiency, is not required to high pressure, safety advantages of higher, It is widely used at various lighting fields, but (such as headlight, street lamp, Tunnel Lamp, wide when for some big area illuminations Field illumination, industrial light, garden lamp etc.), at this moment the power of LED is relatively big, and the life-span of LED light source has with the operating temperature of node Closer contact, current LED in the course of the work only 15%~25% electric energy be converted into luminous energy, remaining electric energy Nearly all change into heat energy, make the temperature of LED raise, and temperature often increases by 10 degree of its reliabilities and will reduce half.Exist especially In great power LED, heat radiation is a big problem.If dispelled the heat, bad meeting directly results in LED quick aging, and stability reduces, simultaneously Dispel the heat and bad can produce serious light decay and affect the life-span of lamp.
The radiating mode major part employing fan of prior art carries out dispelling the heat and meets the cooling requirements of high-powered LED lamp, There is obvious technological deficiency in this method: (1), because the basic life-span of LED is 50000 hours, the life-span of fan is very Difficult that meet the most long-time needs, once fan cisco unity malfunction, high-powered LED lamp will damage, and arranges fan dress Put and add the consumption of the energy, cause the waste of the energy;(2) existing heat abstractor uses metal material to make, matter Amount is big, increases assembly difficulty.
To this, currently mainly there is following patent in China:
Patent publication No.: CN104296106A, discloses a kind of heat dissipation device of LED lamp, including heat transfer silk and conducting strip, described scattered Thermal is stacked by several heat conductive sheet layer, leaves certain space between adjacent two conducting strips, and described heat transfer silk is successively Through several conducting strips, the construction for heat radiating device of several conducting strips described composition is cylindrical, and described conducting strip material is Heat-conducting plastic.The present invention provides a kind of good heat dissipation effect, safe and reliable LED heat sink for lamp, use heat transfer silk and Conventional fan heat radiation replaced by conducting strip, solves short problem in fan service life, uses plastic material to carry out heat conduction, solve tradition The problem that heat abstractor quality is big.But, the conducting strip dense arrangement of this device, it is unfavorable for that air circulates, in actual use Radiating effect is unsatisfactory.
Summary of the invention
For solving the problem of above-mentioned existence, it is an object of the invention to provide the heat dissipation device of LED lamp of a kind of Homogeneouslly-radiating.
For reaching above-mentioned purpose, the technical solution used in the present invention is: the heat dissipation device of LED lamp of a kind of Homogeneouslly-radiating, its It is characterised by, including: LED and cooling lamp holder;Described cooling lamp holder includes: body, one group of first fin and one group second Fin;Described body, for strip, its lateral opening, opening part is provided with light trough;One group of first fin, is arranged at body On incline, body incline stretch out, be arranged radially;One group of second fin, is arranged on the first fin, by The face at one fin place is to stretch out;Described second fin extended to same direction is parallel to each other;First fin Second fin of both sides is relative to the first fin axisymmetricly;Second fin of described first fin and upper setting thereof Summit line is triangle;Described LED is arranged in the light trough of cooling lamp holder body.
Further, in one group of first fin, the length of every piece of fin is equal.
And, in described second fin, one group of fin near body passes through up and down with body, the first fin composition Logical gas channel, this group fin junction all seals welding.
Separately, the thickness of the first fin is 2 ~ 3 times of the second fin.
Separately having, the second fin all presents unsymmetric structure, and fin surface is vertically formed with groove.
Again, the cross section of described groove is circular arc, rectangle, triangle, trapezoidal or waveform.
Further, described body, the first fin and the second fin are one-body molded or seal welding.
Also, described first fin is red copper.
Further, described second direction, fin place and body incline angle are 60 degree.
The beneficial effects of the present invention is: utilize stack effect, strengthen channel inner surface cross-ventilation effect, improve heat radiation Efficiency.Along with the first fin length increases, heatsink temperature is more and more lower, and the long meeting of fin length simultaneously causes air stream During Tong, boundary region is thickening, causes boundary region between abutting fins to coincide mutually, deteriorates heat transfer.Therefore, the present invention second dissipates Backing is gradually reduced along the first fin direction length that stretches out, thus Homogeneouslly-radiating, optimize radiating effect, reduce material and become This.Configuration the most of the present invention is graceful, and corresponding appearance design can be coordinated to reach the effect that device beautifies.
Accompanying drawing explanation
Fig. 1 is the structural representation of the heat dissipation device of LED lamp of a kind of Homogeneouslly-radiating provided by the present invention.
Fig. 2 is the structural representation of the second fin of the heat dissipation device of LED lamp of a kind of Homogeneouslly-radiating provided by the present invention Figure.
Detailed description of the invention
Following example are used for illustrating the present invention, but can not be used for limiting the scope of the present invention.
With reference to Fig. 1 ~ Fig. 2, the heat dissipation device of LED lamp of a kind of Homogeneouslly-radiating provided by the present invention, it is characterised in that bag Include: LED 4 and cooling lamp holder;Described cooling lamp holder includes: body 1, one group of first fin 2 and one group of second fin 3; Described body 1, for strip, its lateral opening, opening part is provided with light trough 11;One group of first fin 2, is arranged at body 1 side On rib, body 1 incline stretch out, be arranged radially;One group of second fin 3, is arranged on the first fin 2, by The face at the first fin 2 place is to stretch out;Described second fin 3 extended to same direction is parallel to each other;First dissipates Relative first fin 2 of second fin 3 of backing 2 both sides is axisymmetricly;Described first fin 2 and the second of upper setting The summit line of fin 3 is triangle;Described LED 4 is arranged in the light trough 11 of cooling lamp holder body 1.
