Abstract
The utility model discloses a lamp shade with heat conduction pipes, which includes a lamp shade casing, wherein an aluminum baseplate is arranged in the lamp shade casing and LED lamp beads are laid on the aluminum baseplate; vertical slotted channels are arranged at the bottom of the lamp shade casing; the aluminum baseplate is laid on the inner bottom of the lamp shade casing; heat conduction pipes inserted in the vertical slotted channels in a penetrating manner and contacted and connected with the bottom of the aluminum baseplate are arranged on the lamp shade casing; and radiating fins integrally formed with the lamp shade casing are arranged inside the bottom of the lamp shade casing. The heat conduction pipes are copper pillars and have excellent heat transmission performance, so that heat quantity at one end can be quickly transmitted to the other end, and the heat conduction pipes are filled with refrigeration liquid, so as to form an optimum heat switching process, which is realized not only through metal to transmit heat quantity, but also through refrigeration liquid to serve as a heat exchange media for the reason that the refrigeration liquid has the heat conductivity of about 200 times of that of copper as well as excellent heat responsiveness, as a result, when the heat conduction pipes perform heat radiation, circulatory heat radiation is formed, so as to shorten more than 30% heat radiation time (high-speed heat absorption and cooling).
Description
Technical field
The utility model relates to a kind of lampshade structure, relates in particular to a kind of lampshade simple in structure, heat radiation when helping LED lamp pearl luminous.
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.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provide a kind of simple in structure, heat radiation comprehensively, the special-purpose lampshade of LED lamp pearl of environmental protection, miniaturization.
The technical scheme that the existing lampshade of the utility model solution dispels the heat to LED lamp pearl is: a kind of lampshade with heat pipe; Comprise a lampshade shell; Be provided with aluminium base in the lampshade shell and on aluminium base, be equipped with LED lamp pearl; Wherein aforesaid lampshade shell bottom is provided with vertical channels; Aluminium base is layed in lampshade shell at interior the end, and lampshade shell is provided with and interts into contacting the heat pipe that is connected in the vertical channels and with the aluminium base bottom, and lampshade shell is provided with the fin that is integrally formed with lampshade shell in the bottom.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 aluminium base, 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: the aforementioned lamps over body case is aluminum material or plastics; The material of lampshade shell is selected to decide according to actual operating position.In addition, aforesaid heat pipe is provided with three; 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 lampshade of the utility model has following advantage:
⑴ volume is little: product takes up room little, satisfies the miniaturization of LED control system, and integrated needs in original lampshade, add the original structure that heat pipe can not influence lampshade, and the heat pipe occupation space are minimum;
⑵ strengthen the radiating effect of LED lamp pearl: the heat pipe thermal resistance is minimum, in limited space, can promptly conduct more heat, and heat can be expelled to the external environment condition from LED lamp pearl fast, and assurance LED lamp pearl and long term device are worked in low temperature environment;
⑶ increase the service life: radiating effect strengthens, thereby makes prolong the service life of LED lamp pearl.
