Abstract
The invention discloses an LED lamp pedestal radiating fin, belongs to the technical field of lighting instruments. The LED lamp pedestal radiating fin comprises a circular radiating fin body, wherein a plurality of U-shaped slots with outward openings, which are uniformly distributed in a radial direction, are formed in the end surface of the radiating fin body; the openings of the U-shaped slots are gradually reduced from outside to inside; the radiating fin body at the two ends of each U-shaped slot is provided with through holes; a heat conducting tube is arranged in each U-shaped slot; and the two ends of each heat conducting tube get out from the through holes.
Description
Technical field
The present invention relates to ligthing paraphernalia technical field, the pedestal fin of especially a kind of LED.
Background technology
LED is to adopt high brightness white light-emitting diode as the ligthing paraphernalia of luminous source, because of its there are energy-saving and environmental protection, life-span length, feature that volume is little are widely used; But make it more early light decay occur owing to LED also exists the more high meeting of its junction temperature, cause the problem that its service life is more short; Namely junction temperature is 105 degree, brightness was down to the service life of 70% only less than 10,000 hours, 20,000 hours are just had when junction temperature is reduced to 95 degree of its service lifes, and junction temperature is reduced to and just can reach 50,000 hours 75 degree of its service lifes, and junction temperature more can extend its service life to more than 80,000 hours when continuing to be reduced to 65 degree, therefore, the heat dissipation element of LED how is transformed, reduce the junction temperature of LED as far as possible, be the new problems constantly researched and solved of people.
Summary of the invention
The technical problem to be solved is to provide a kind of LED lamp base fin, the problem that this LED lamp base fin can solve to affect its service life because LED radiating rate is relatively slow.
In order to solve the problems referred to above, the technical solution adopted in the present invention is: this LED lamp base fin, include the heat sink body of circle, the end face of described heat sink body offers the equally distributed outwardly open U-type groove of multiple radial direction, the opening ecto-entad of described U-type groove is gradually reduced, being positioned in the described heat sink body at described U-type groove two ends and all offer through hole, be provided with heat pipe in each described U-type groove, the two ends of described heat pipe all pass from described through hole.
In technique scheme, technical scheme is it may also is that described heat sink body is made up of aluminum more specifically; Described heat pipe is made up of high-temperature superconductor material, and the diameter of described heat pipe is 6 millimeters.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, due to the end face of heat sink body offers multiple radial direction equally distributed outwardly open outer big in little U-type groove, and U-type groove is provided with its end and wears out the heat pipe of heat sink body; When LED heating makes heat sink body temperature raise, heat pipe can conduct the heat of heat sink body rapidly along its pipeline, makes LED obtain radiating and cooling;
2, owing to heat pipe is made up of high-temperature superconductor material and the diameter of heat pipe is 6 millimeters;The thermal resistance of heat pipe is only small, can be distributed to space rapidly by the heat that LED sends; Ensure that in practical application that the junction temperature of LED is less than 65 degree, the service life of LED is more than 10 hours.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the upward view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
LED lamp base fin shown in Fig. 1, Fig. 2, include the heat sink body 1 of circle, the end face of heat sink body 1 offers the equally distributed outwardly open U-type groove of 3 radial directions, the opening ecto-entad of U-type groove is gradually reduced, it is positioned in the heat sink body 1 at U-type groove two ends and all offers through hole, being provided with heat pipe 2 in each U-type groove, the two ends of heat pipe 2 all pass from through hole; Heat sink body 1 is further opened with screw through hole 4 and electric wire mounting hole 3 are installed; Heat sink body 1 is made up of aluminum; Heat pipe is made up of high-temperature superconductor material, and the diameter of heat pipe is 6 millimeters. The thermal resistance of heat pipe is only small, when LED heating makes heat sink body temperature raise, can be distributed to space rapidly by the heat that LED sends, make LED obtain effective radiating and cooling; Ensure that in practical application that the junction temperature of LED is less than 65 degree, the service life of LED is more than 10 hours.
