Abstract
The invention discloses a light-emitting diode (LED) lamp radiator, which comprises a heat conduction pipe and radiating fins. The LED lamp radiator is characterized by consisting of a plurality of radiating fins formed in laminating mode, a certain gap is reserved between every two adjacent radiating fins, and the heat conduction pipe sequentially penetrates through the plurality of radiating fins. The heat conduction pipe is in the shape of an L, and the included angle is 30 degrees. The LED lamp radiator resolves the problems that an LED lamp in the prior art adopts a fan for radiation, service life of the fan is short, long-time and reliable operation cannot be achieved, LED light source attenuation is led to be greater when thermal grease is used for radiation and a wide range of application in large-area illumination is impossible, and is good in radiating effect, safe and reliable in use.
Description
Technical field
The present invention relates to a kind of radiator, particularly relate to a kind of LED lamp radiator.
Background technology
High-pressure mercury lamp is mostly adopted in the Traditional Road illumination; But along with development of science and technology; The LED lamp relies on the high and low power consumption of luminous efficiency, does not need advantages such as high pressure, security height, has been applied in various lighting fields widely, but when being some big area illuminations (such as headlight, street lamp, Tunnel Lamp, plaza lighting, industrial light, garden lamp etc.); At this moment the power of LED lamp is bigger; The life-span of led light source and the operating temperature of node have closer getting in touch, and at present the LED lamp has only 15%～25% electric energy to convert luminous energy in the course of the work, and remaining electric energy nearly all changes into heat energy; The temperature of LED lamp is raise, and every increase by 10 its reliabilities of degree of temperature will reduce half the.In great power LED, heat radiation is a big problem especially.Bad meeting directly causes the LED quick aging if dispel the heat, and stability reduces, bad can the generation life-span that serious light decay influences lamp of dispelling the heat simultaneously.
The radiating mode of prior art has the heat radiation requirement of adopting fan to dispel the heat and satisfy high-powered LED lamp; There is tangible technological deficiency in this method, because the basic life-span of LED lamp is 50000 hours, the life-span of fan is difficult to satisfy so long-time needs; In case fan cisco unity malfunction; High-powered LED lamp will damage, and the consumption that fan assembly has increased the energy again is set, and has caused the waste of the energy.Existing LED lamp product adopts thermal grease to dispel the heat in order to reduce the cost simultaneously, can make the light source decay of LED bigger, can't be applied on the large area lighting widely.
Summary of the invention
The LED lamp adopts the fan heat radiation in the prior art in order to solve; Fan weak point in service life is reliability service for a long time; And thermal grease dispels the heat, and can make the light source decay of LED bigger, can't be applied in the problem of large area lighting widely; The invention provides a kind of good heat dissipation effect, safe and reliable LED lamp radiator.
In order to address the above problem, the technical scheme that the present invention taked is:
A kind of LED lamp radiator; Comprise heat pipe and radiating fin, it is characterized in that: said radiator is formed by several radiating fins are range upon range of, leaves certain gap between adjacent two radiating fins; Said heat pipe passes several radiating fins successively, and said heat pipe is L-shaped.
Aforesaid a kind of LED lamp radiator is characterized in that: the heat spreader structures that said several radiating fins are formed is cylindrical or square.
Aforesaid a kind of LED lamp radiator is characterized in that: the angle of said " L " shape heat pipe is 30 degree.
The invention has the beneficial effects as follows:
LED lamp of the present invention heat pipe capable of using and radiating fin dispel the heat; The heat that distributes in the time of can great power LED being worked is transmitted to heat pipe effectively; Heat pipe rely on its extremely strong heat-transfer capability with the heat high efficiency of transmission to radiating fin, the heat exchange through radiating fin and air distributes heat.Heat pipe of the present invention and radiating fin are not fragile simultaneously, and long service life is safe and reliable, and the light source decay of LED is increased, and can be applied on the large area lighting widely.
Description of drawings
Fig. 1 is the structural representation of LED lamp radiator of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further description.
As shown in Figure 1; A kind of LED lamp radiator; Comprise heat pipe 1 and radiating fin 2, radiator is by 2 range upon range of compositions of several radiating fins, and the heat spreader structures that radiating fin 2 is formed is cylindrical or square; Leave certain gap between adjacent two radiating fins 2, heat pipe 1 passes several radiating fins 2 successively.
Heat pipe 1 is L-shaped during design, and the angle of " L " shape heat pipe 1 is 30 degree, has increased the length and the area of heat pipe like this, makes that heat pipe 1 radiating effect is better.
Heat pipe 1 of the present invention is not fragile with radiating fin 2; Long service life; Safe and reliable .LED lamp heat pipe 1 capable of using dispels the heat with radiating fin 2; The heat that distributes in the time of can great power LED being worked is transmitted to heat pipe effectively, and heat pipe 1 relies on its extremely strong heat-transfer capability that the heat high efficiency of transmission is arrived radiating fin 2, through the heat exchange of radiating fin 2 with air heat is distributed.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
Claims (3)
1. LED lamp radiator; Comprise heat pipe and radiating fin, it is characterized in that: said radiator is formed by several radiating fins are range upon range of, leaves certain gap between adjacent two radiating fins; Said heat pipe passes several radiating fins successively, and said heat pipe is L-shaped.
