Description
Technical field
The utility model relates to a kind of LED lamp, relates in particular to a kind of heat radiation rapidly and efficiently, simple in structure, the LED lamp of saving the space.
Background technology
Along with the development that the LED technology is maked rapid progress, device such as LED street lamp, projecting lamp is to high-power, densification, lightweight development.LED product and device are in application process, and factors such as heat radiation, electrostatic defending, welding have very big influence to its characteristic, need cause application end client's great attention.
Because the restriction of semiconductor light-emitting-diode wafer technologies at present; The photoelectric transformation efficiency of LED is still waiting to improve, and LED is higher because of its power, and nearly electric energy more than 60% will become heat energy and discharge (along with development of semiconductor; Photoelectric transformation efficiency can improve gradually); This just requires terminal client in the application of LEDs product, carry out heat radiation work, to guarantee LED product operate as normal.The heat increase that the LED lamp is produced in unit volume is very fast, and therefore the LED components and parts being carried out thermal control is its major issue that advances.Meanwhile; Effectively area of dissipation but reduces relatively, because the reliability and the temperature of LED element are inversely proportional to, rate of breakdown raises and the exponent function relation growth with LED components and parts temperature; Therefore should strictly control LED components and parts temperature, thereby solve the LED light decay problem that causes because of the deficiency of dispelling the heat; Therefore heat dissipation technology has become the emphasis problem of studying reliably.The heat that LED lamp pearl is sent in the prior art mainly is to contact with LED lamp pearl through fin directly to dispel the heat, though this radiating effect is effective, quick inadequately and poor effect especially needs in time heat radiation rapidly for the high-power LED lamp pearl; The heat that can not in time dispel the heat makes the temperature of LED lamp pearl constantly raise; Heat distributes in the space between lampshade and LED lamp pearl and forms hot-air simultaneously; Hot-air is full of in lampshade and can not get dispelling the heat timely, causes the light decay problem of LED lamp pearl, reduces the service life of LED lamp pearl.
In the prior art, the technology of utilizing energy storage plate and heat pipe to distribute heat exists, but because this technology receives the restriction of technical conditions; Structurally exist tangible deficiency; Show that heat pipe need pass the lamp holder lamp housing and be connected on the energy storage plate in the lamp holder, processing, very inconvenient when installing, and also effective work of heat pipe is directive; And after heat pipe passed in the lamp holder lamp housing, the adjusting of its direction had just received the considerable restraint of lamp housing; In addition; Energy storage plate is closed in the lamp housing; In case radiator portion can not be brought into play heat sinking function because of inappropriate setting (as putting upside down), the heat energy of energy storage plate just accumulates in the lamp housing of sealing, can cause the temperature of LED lamp in the extremely short time, to rise rapidly; The LED lamp is damaged rapidly under the high temperature that rises rapidly, thereby the service failure rate of lamp is risen significantly.In order to address the above problem; " a kind of high-power integrated LED lamp " of Chinese invention patent 201020133282.X; Though the disclosed technology of this patent has solved the problem of above-mentioned prior art; But because energy storage plate is not directly to contact with U type heat pipe, its radiating effect is not the best, and the attaching parts between energy storage plate and the U type heat pipe are more and complicated; In addition; Owing to the space that U type heat pipe itself is shared is more, and the radiating effect of wall scroll U type heat pipe is not good, and this just must adopt many U-shaped heat pipes and more fin; Just can reach desirable radiating effect; Use volume and space that this has just increased whole lamp body are unfavorable for using and saving of space, have strengthened mounting hardness.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of simple in structure, convenient processing and installation, environmental protection, heat radiation efficiently to reach the LED lamp of miniaturization.
The technical scheme that the utility model solves existing LED lamp heat radiation is: a kind of LED lamp that adopts the heat pipe heat radiation; Comprise a lampshade; Be provided with aluminium base in the lampshade and on aluminium base, be equipped with the high-power LED lamp pearl; One port of lampshade is provided with and the smooth energy storage plate that is adjacent to of aluminium base, and wherein aforesaid lampshade outer surface is provided with many fin that are adjacent to the lampshade outer surface, and energy storage plate is connected with at least one heat pipe that passes each fin.The heat pipe of the utility model is the copper post, and heat pipe has good heat transfer performance, can be delivered to the other end rapidly from the heat of an end; In heat pipe, be loaded with refrigerating fluid; Just realized the hot transfer process an of the best, this transfer process is not only to transmit heat through metal, but utilizes the interior refrigerating fluid of copper pipe as heat-exchange medium; The heat conductivity of refrigerating fluid is about 200 times of copper, and refrigerating fluid has good thermo-responsive.This heat pipe also has stable cooling effect; Different with method (using water proof sheet and cooling tube) in the past; Heat pipe seldom makes refrigerating fluid reduce because of getting rusty with reason such as incrustation scale causing cooling effect to descend; Do not worry that also refrigerating fluid can evaporate and leak, reduced a large amount of maintenances and maintenance work, the temperature range that heat pipe uses is 50 ℃ to 200 ℃; When heat pipe dispels the heat, can be shaped cycle heat radiation and shorten the heat radiation time (heat absorption and cooling at a high speed) more than 30%.The luminous heat that sends of LED lamp pearl is delivered to rapidly the heat pipe from energy storage plate, is aided with the fin heat radiation again, can reach LED lamp pearl quick heat radiating and the effect that keeps low temperature.
As the further design to the aforementioned techniques scheme: aforesaid heat pipe is provided with three, and article one heat pipe is connected with lampshade after directly passing energy storage plate, and two heat pipes are connected with the energy storage plate symmetry respectively and form cross with article one heat pipe in addition; Also can be that aforesaid heat pipe is provided with six, every heat pipe all be connected with energy storage plate and be evenly distributed.Consider the thickness situation of energy storage plate and heat pipe, energy storage plate can only allow a heat pipe to pass.Bar number and distributing position through heat pipe and fin rationally are set can strengthen the heat radiation of LED lamp pearl, make the heat radiation of LED lamp pearl reach the effectiveness of getting half the result with twice the effort.
In sum, the LED light fixture of the utility model has following advantage:
⑴ volume is little: product adopts heat pipe to be adjacent to the connected mode that is connected the lampshade outer surface with fin, and is simple in structure and volume is little; Easy for installation, and save the space;
⑵ strengthen the radiating effect of LED lamp pearl: heat pipe directly contacts with energy storage plate, and promptly energy storage plate directly transmits heat to heat pipe, strengthened the radiating effect of LED lamp and shortened the heat radiation time, has avoided the indirect heat transfer of heat pipe and energy storage plate in the prior art;
