Abstract
The utility model discloses a lamps and lanterns radiator subassembly, including the radiator, its characterized in that: the radiator is internally provided with a heat exchange element capable of exchanging heat, the heat exchange element is connected with the light source module, and a support plate is arranged between the heat exchange element and the light source module. The radiator is of an aluminum extrusion molding structure, can fully utilize the action of air convection to dissipate heat, has small volume, is flat in installation matching plane, and has high precision when being combined with accessories; meanwhile, the surface treatment of the radiator is very good and smooth, which is beneficial to welding and the like. The radiator assembly has the advantages of simple and reasonable structure, small volume, convenient processing, manufacturing, installation and arrangement, large radiating area, small thermal resistance, high heat conductivity coefficient and good radiating performance, and can meet the radiating requirement of power electronic components such as a high-power LED integrated packaging light source and the like.
Description
Technical field
The utility model relates to a kind of lamp radiator assembly, relates in particular to the lamp radiator assembly that a kind of volume that dispels the heat is little, can distribute big wattage gathering heat that led light source produces.
Background technology
At present, along with the development and the maturation of LED technology, the performance indications of LED day by day significantly improve, and have obtained using widely at lighting field.LED compare with the lighting of general photo-voltaic power supply adapted have the life-span long, heating is low, not fragile, power consumption is little and more energy-conservation outstanding advantage.
At present, when using LED, be installed in many light emitting diodes by the mode of stipulating usually and form the LED module on the aluminium base, pass to heat to lamp outer casing through the aluminium base thermal conductive surface and dispel the heat.In order to reach the heat radiation requirement, often need increase the lamp outer casing area of dissipation, increased the weight of whole lighting so on the one hand, be inconvenient to use, also certainly will increase manufacturing cost on the other hand.Particularly for the power that is applied to throw light on for for several watts to hundreds of watts the great power LED; If do not add cooling measure, the led chip junction temperature can rise rapidly, causes the light emission rate of LED and life-span sharply to be reduced; Particularly when junction temperature rose above maximum allowable temperature, LED can lose efficacy because of overheated.Present employed LED heat dissipation technology scheme all in various degree exist various defectives and deficiencies such as radiating effect is poor, poor reliability, limited the extensive use of great power LED etc. largely.General heat dissipating method comparatively commonly used is to adopt the hot plate of high conduction coefficient and the welding of fine aluminium fin to conduct heat.
Summary of the invention
Advantages such as the purpose of the utility model is to solve existing problem in the existing lamp radiator assembly, and that the lamp radiator assembly of the utility model has is simple in structure, volume is little, radiating effect is fast and radiating effect is good.
The utility model solves the technical scheme that its technical problem adopted: a kind of lamp radiator assembly; Comprise radiator; It is characterized in that: be provided with the heat exchange element that can carry out heat exchange in the described radiator; Heat exchange element connects the light source module, is provided with support plate between heat exchange element and the light source module.This radiator is the aluminium extruded shaped structures, can make full use of cross-ventilated effect heat radiation, and the volume of radiator own is very little, and the installation of radiator cooperates the plane smooth, and combining with accessory is to have the high precision of valency; Simultaneously, the surface of radiator must electroplating processes be beneficial to the welding of hot plate or heat pipe, and anodic oxidation increases radiating efficiency and handles also very good smooth, helps welding etc.
As the further design to the aforementioned techniques scheme: aforesaid heat exchange element is hot plate or heat pipe.Hot plate or heat pipe bending and molding, this contact installation surface is along sliding smooth, and is closely good with the contact-making surface of LED pyrotoxin, hot plate or heat pipe with can weld well with the radiator of aluminium extruded after support plate and light source module are fixedly connected.
As the further design to the aforementioned techniques scheme: be provided with central through hole in the aforesaid radiator and be positioned at the peripheral many heat radiation through holes of through hole with being provided with, heat exchange element is coated in the heat-conducting cream centering through hole or is welded in the central through hole.
As to the aforementioned techniques scheme more further the design: aforesaid central through hole back is provided with the plastic cover capping.
In sum; The utility model the advantage of lamp installation bracket component and light fixture following: simple and reasonable, volume is little; Processing and fabricating and mounting arrangements are convenient and area of dissipation is big; Thermal resistance is little, thermal conductivity factor is high, and perfect heat-dissipating can satisfy the heat radiation requirement of the integrated packaged light source constant power of great power LED electronic devices and components.
