Description
Technical field
The utility model relates to technical field of LED illumination, and in particular to a kind of illumination heat radiator and the illumination group using it
Part.
Background technique
For living in for the increasing contemporary people of pressure, field, which is encamped, has become a kind of trend trend, people
Traditional stadiums are gradually left, wilderness is moved towards, are indulged between scenery with hills and waters.And field camping illumination nature is essential, one
A supply illuminator for using for a long time of camping is particularly significant.
Traditional field, which encamps to illuminate, is often used flashlight and candle lamp, though it is easy-to-use, it is easy to carry, there are many disadvantages
End, people must be manipulated when in use with hand, and in field, the action of people will receive constraint to a certain extent.Meanwhile it is general
The functionality of the logical lamps and lanterns such as flashlight and candle lamp is also relatively single, and the design of outdoor lamp, which is often caught in, innovates limited be stranded
Border.
As the new generation of green light source and lighting engineering of environmental protection and energy saving, great power LED is rapidly developed in recent years.Greatly
Power LED still has the unsmooth and not high problem of light emission rate that radiates, because heat dissipation directly influences the reliability of LED, Jin Erying
It rings and arrives its service life and application, and light emission rate is low directly constrains the development of LED, so the research to LED heat dissipation design just seems
It is increasingly important.In order to solve the heat dissipation problem of great power LED, domestic and foreign scholars and engineer all LED chip, encapsulating structure,
All various aspects such as encapsulating material and external cooling mode have carried out a large amount of research.There are various excellent LED encapsulating structures, such as
The chip on board formula encapsulating structure (COB, chip onboard) that pinned encapsulation, surface-adhered type and latest development are got up
Deng.Using COB technology, directly LED chip is encapsulated on aluminum substrate, shortens the distance of the passage of heat and heat transfer, to drop
The low junction temperature of LED.COB encapsulation, which refers to, is directly anchored to LED chip on printed wiring board (PCB), between chip and wiring board
The LED encapsulation technology being electrically connected by wire bonding.It can encapsulate dozens or even hundreds of in the region of 1 very little
A chip, eventually forms area source.Compared with point light source encapsulation, COB area light source encapsulation technology has cheap (only same core
1/3 or so of piece), save space, heat dissipation be easy, luminous efficiency improve, packaging technology technology maturation the advantages that.
High-power COB is encapsulated, heat dissipation is to influence the vital factor of its long-term reliability.COB encapsulating products
Junction temperature, which increases, can reduce the whole efficiency of LED, reduce forward voltage, cause to emit light red shift, reduce the service life and can
By property.
The selection of LED encapsulation material has a great impact to the heat dissipation and light extraction efficiency of LED component.Therefore, high to find
The excellent encapsulating material of heating conduction, optimizing from material selecting party in face of the heat dissipation performance of device is necessary.
The photoelectric conversion efficiency of COB encapsulation at present is low, and 70% even higher electric energy is converted into thermal energy, especially chip side table
The heat-sinking capability of face and upper surface is very poor, therefore the heat overwhelming majority generated passes to chip bottom by way of heat transfer
It is heat sink, it is being consumed in a manner of thermal convection.In addition, since COB light source itself is without heat-sinking capability, it is necessary to additional radiator ability
It working normally, COB light source must fit closely with radiator and could efficiently export heat, otherwise due to there are the air gap,
The thermal coefficient very little of air, is non-conductor, it will forms thermal contact resistance between chip and radiator, reduces heat dissipation effect
Fruit.
Therefore, all realize the heat transfer of chip to radiator by an adhesives between radiator and light source.It is logical
Often, between COB light source and radiating fin coated with thermally conductive silicone grease to reduce thermal resistance.
Heat-conducting silicone grease is commonly called as " heat-conducting cream " or " thermal grease ", is to be generally filled in high efficiency and heat radiation material paste in LED light
Between the bracket and aluminum substrate or aluminum substrate and radiating shell in source, its mobility is very good, and can sufficiently moisten two kinds of infiltration
Thermally conductive material surface is needed, so that a low-down thermal resistance interface is formed, among LED light source and radiator contact surface
Air heat conduction efficiency is high.From the point of view of fundamental characteristics, silicone grease is usually to make base oil with extraordinary silicone oil, with novel metal oxide
Make filler, is equipped with multiple functions additive, the paste of the white or other colors that are process through special technique, thermal conductive silicon
Rouge has the characteristics that splendid thermal conductivity, electrical insulating property, stability in use, resistant of high or low temperature, is that current high-power LED lamp is normal
Heat Conduction Material.
The thermal conductivity of heat-conducting silicone grease increases with the increase of filer content, the increased performance drop of simultaneous viscosity
It is low, it is difficult to which that flowing or deformation influence the gap being filled up completely between chip and radiator.Therefore, heat filling appropriate is selected,
It realizes the high thermal conductivity of heat-conducting silicone grease, and guarantees that low k value is necessary.
Graphene is known as the king of new material, and there is ultra-thin, ultralight, superhigh intensity, superpower electric conductivity, excellent room temperature to lead
Heat and light transmission, due to being applied to multiple fields as a kind of heat sink material with excellent heating conduction.Applicant
Early stage has begun working on application of the graphene in heat-conducting silicone grease, and has applied for CN201210119361.9 patent, by
Graphene is added in silicone oil, using the heating conduction of graphene, realizes that the thermal coefficient of system entirety improves, and pass through addition
The phenomenon that multi-walled carbon nanotube, solution silicone oil and heat filling separate.In the art, although can be very good to improve thermal conductive silicon
The heat transfer efficiency of rouge, but the graphene used is not limited, therefore the performance of heat-conducting silicone grease and unstable, single layer
Graphene-based in technical reason, the yield rate of material is lower, therefore leads to the at high cost of material, and graphene additive amount
Higher, shared space becomes smaller basic silicone oil in the composite, and the lubricating action that silicone oil is played weakens, composite material it is glutinous
Angle value then shows to increase, degradation, and a part of the addition of multi-layer graphene as heat filling, fills out to metal heat-conducting
For material, the influence of the thermal conductivity of final composite material is not obvious, and with the continuous development of chip technology, to chip
Cooling requirements are higher and higher, and the heat-conducting silicone grease for adding multi-layer graphene is increasingly difficult to meet the needs of chip development.
Light fixture provided by the utility model is the LED vehicle outdoor travel lamp to radiate using graphene, design concept
Innovation, it is light-weight, it is convenient for carrying.Relative to traditional LED vehicle outdoor travel lamp, the product thermal diffusivity excellent using graphene
Can, the heat dissipation effect of lamps and lanterns is substantially increased, the service life of lamps and lanterns is increased, is plugged in using automobile, reduce electric energy
Use, light source design is concentrated using COB, light efficiency is high.
