Abstract
A high-power LED radiator belongs to the technical field of a light source radiator and comprises an aluminium base plate, cooling plates and a heat pipe, wherein one side of the aluminium base plate is provided with a convex platform which is used for installing an LED light source, the heat pipe is divided into an upper line and a lower line that extend out from the side of the aluminium base plate, and a plurality of cooling plates are connected in series to the heat pipe. Due to the adoption of the high-power LED radiator used for cooling an LED, the LED light source can be installed on the aluminium base plate and is sealed in a hermetic light fitting by using the structure of the convex platform, while all parts outside the convex platform of the radiator are completely exposed outside. The utility model has the advantages that the structural design can ensure that the radiating efficiency of the radiator of the heat pipe is exerted to the utmost extent on the premise that the LED light source is sealed, thereby providing guarantee for reducing light decay of the LED light source and prolonging the service life thereof. The structure has simple assembly and flexible and convenient use.
Description
Technical field
The utility model belongs to the heat sink technology field of led light source, and a kind of radiator that is used for high-power LED light source particularly is provided.
Background technology
LED (light emitting diode) light source is a kind of semiconductor lighting product, under same power, the illuminance of led light source is far longer than the illuminance of conventional light source, if but junction temperature that can not better controlled led light source PN junction, its illuminance will be had a greatly reduced quality, for the quality of led light source PN junction junction temperature radiating effect, directly affect the light decay and the service life of led light source.
The utility model content
The purpose of this utility model is to provide a kind of high-power LED radiator, overcomes the shortcoming of current high-power LED illuminating lamp poor heat radiation, improves radiating efficiency, obviously promotes the effect to the LED heat radiation.
Of the present utility modelly be made of aluminium base, fin, heat pipe, a side of aluminium base has a raised platforms, is used to install led light source, has processed the screw that is used to install led light source on the raised platforms of aluminium base; Heat pipe is divided into two rows, stretches out polyphone 10-20 sheet fin on the heat pipe from the aluminium base side.The structure of this radiator can be used for the outlet structure of radiator.
When the utility model is used for the LED heat radiation, led light source can be installed on the aluminium base of raised platforms one side, structure by raised platforms, led light source is encapsulated in the airtight light fixture, and all parts beyond the radiator raised platforms, outside can being exposed to fully, give full play to the radiating efficiency of heat-pipe radiator.
The invention has the advantages that, the tubular radiator of heat conduction is higher than the radiating efficiency of common Section Bar Heat Sinks, the radiator outlet structure can reach the purpose of effective raising radiating effect, make the making high-power LED lighting fixture become possibility, lower the light decay of LED lighting greatly, improved its service life.
Description of drawings:
Fig. 1 is a kind of structural representation of the present invention.Wherein, aluminium base 1, heat pipe 2, fin 3, led light source 4.
Fig. 2 is the led light source schematic diagram.
The specific embodiment:
Be described further below in conjunction with the specific embodiment of accompanying drawing this patent.
1, with aluminum profile extrusion aluminium base 1, aluminium base one side processes a convex plane, and screw is installed in processing
2, heat pipe 2 and fin 3 are passed through interference fit
When 3, using led light source 4 by being installed, screw is assemblied on the convex plane of radiator.
The utility model, when being used for the led light source heat radiation, led light source is installed on the aluminium base, by the structure of raised platforms, led light source can be encapsulated in the airtight light fixture, and all parts beyond the radiator raised platforms, outside can being exposed to fully, this structural design can be brought into play the radiating efficiency of heat pipe radiator to the utmost under the prerequisite that guarantees the led light source encapsulation, for the light decay that lowers led light source provides guarantee its service life with improving.This structure assembling is simple, flexible and convenient to use.
