Abstract
The utility model provides an LED (light emitting diode) radiating structure, belonging to the field of LED illumination. The LED radiating structure comprises an LED lamp bead 1, an LED substrate 2, easily-gasified liquid 3, a radiating fin 4, a sealing ring 5 and a sealing cover 6. The radiating fin is provided with multiple radiating ribs; a radiating fin base and the radiating ribs are provided with grooves to obtain the largest internal surface area, and step-shaped through holes are reserved on the back; the LED lamp bead is arranged on the LED substrate through reflow soldering; the LED substrate and the radiating fin base form a sealing structure through a welding, sticking or gumming mode; the easily-gasified liquid is gasified very easily when heated and is filled in the internal space formed between a radiator and the LED substrate; the sealing ring is placed in the step-shaped through hole of the radiating fin; and the sealing cover compacts the sealing ring to completely seal the easily-gasified liquid. The LED radiating structure provided by the utility model has good radiating effect and low cost, and can effectively solve the problem of heat conduction of a high-power LED.
Description
Technical field
The utility model provides a kind of LED radiator structure, belongs to the LED lighting field.
Background technology
Great power LED is because advantages such as its energy-saving and environmental protection, life-span length have obtained application widely; The application that the relevant policies rules are popularized LED is put into effect in countries in the world at present; China has also released planning such as " ten thousand in ten cities " and has promoted the application of LED at illuminating industry, but problem high from the light fixture ubiquity cost of present use, the heat radiation difficulty.The heat radiation of LED light fixture can be divided into heat conduction and heat radiation two parts, and specifically: one, the heat of LED lamp pearl generation is transmitted on the radiating ribs of lamp surface by luminescence chip; Two, the heat on the radiating ribs is dispersed in the air through radiation.Caloric requirement is through a plurality of links such as heat conduction elargol, ceramic substrate, scolding tin, LED substrate, heat conductive silica gel, radiators in heat transfer process.The heat conductive silica gel thermal conductivity factor has only about 2W/m-K preferably at present, and and LED substrate and radiator between must have the air gap, hindered the conduction of heat.
Summary of the invention
The utility model provides a kind of LED radiator structure, and this radiator structure has advantages such as heat conduction velocity is fast, saving cost, effectively reduces the temperature difference between luminescence chip and the radiator, derives heat smoothly.
A kind of LED radiator structure comprises LED lamp pearl 1, LED substrate 2, is prone to gasified liquid 3, fin 4, sealing ring 5 and seal cover 6.Described fin has many radiating ribs; Cooling fin fin base and radiating ribs are partly made groove obtaining maximum interior surface area, and leave stepped through hole, Reflow Soldering LED lamp pearl on the described LED substrate at its back; Form hermetically-sealed construction through modes such as welding, bonding or glue envelopes between LED substrate and the cooling fin fin base; The as easy as rolling off a log gasification when being heated of described easy gasified liquid is filled in the inner space that forms between radiator and the LED substrate, and described sealing ring is put into the stepped through hole of fin; Said seal cover compresses sealing ring, will be prone to gasified liquid and seal fully.The heat that luminescence chip produces is transmitted on the LED substrate through heat conduction elargol, ceramic substrate, scolding tin, owing to be filled with volatile liquid on the LED substrate, this liquid and LED substrate can complete seamless the contacts, and its contact-making surface thermal resistance is almost nil.Volatile liquid is vaporized when being heated and is absorbed heat; High-temperature gas rises rapidly under the effect of gas pressure difference; Run into the radiating ribs part of the lower radiator of temperature, gas liquefaction is back to LED substrate top and release heat, and heat is delivered on the radiating ribs.Volatile liquid conducts out endlessly with heat in the cyclic transformation process of liquid-gas-liquid.After long-time the use, the amount of volatile liquid can reduce gradually, influence radiating effect, can open seal cover at this moment, blocks through hole after charging into volatile liquid once more, can prolong the service life of radiator structure like this, and itself and LED life-span are mated.Have the pyroconductivity higher owing to volatile gas simultaneously, and groove is processed in radiator inside in this structure,, reduce cost so allow the thinner radiator of design to save metal material than metal heat sink.

The specific embodiment
A kind of LED radiator structure comprises LED lamp pearl 1, LED substrate 2, is prone to gasified liquid 3, fin 4, sealing ring 5 and seal cover 6.During use the bead weld of LED lamp is connected on the LED substrate; Through welding, mode bonding or the glue envelope LED substrate and radiator are sealed fully again; From the through hole at radiator back the space between LED substrate and the radiator is evacuated; Charge into volatile gas then, put into sealing ring and block through hole with seal cover.After long-time the use, can open seal cover, block through hole after charging into volatile liquid once more, can prolong the service life of radiator structure like this, itself and LED life-span are mated.
