Description
Technical field
The utility model relates to technical field of LED illumination, and in particular to a kind of LED illumination mould group and the garden using it
Lamp.
Background technique
Residence district public illumination is made of systems such as courtyard road lamp, corridor lamp and parking lot lamps, in daily life, is led to
Various garden lamps are all often set in places such as each cell, square, industrial parks.Garden lamp type is with incandescent lamp
Main, newly-built community can use common energy-saving lamp in recent years, and LED light is not promoted also in cell public illumination.Incandescent lamp is tungsten wire
It shines in incandescent state, power consumption is big, and only less than 10% energy conversion at luminous energy, service life short-range missile causes cell public illumination
Lamp maintenance replacement is frequent.Common energy-saving lamp, art name self-ballasted fluorescent lamp, be using gas discharge principle illuminate, though compare incandescent lamp
Energy conservation, but exist and fear to flash the frequent startings occasions such as unsuitable cell corridor, have the defects of mercury is also easy to produce environmental pollution；And phase
It is approximately LED light more than 1 times with energy-saving lamp power consumption is tested under brightness, and this gap is increasing.
The advantages such as LED light source has environmental protection, energy conservation, efficient, controllable, environmental suitability is strong, the replacement cycle is long.And due to
Garden lamp local environment is not workplace and people's residence time is shorter, of less demanding for lighting effect, therefore LED is one
The ideal garden lamp source of kind.The LED light source that conventional garden lamp uses is usually the point light source that more lamp beads are constituted, and is existed
Solder joint is more, and failure is more, and the use of more lamp beads can have the non-uniform situation of light, therefore more and more factories in recent years
Family attempts to substitute traditional lamp bead point light source using COB area light source, is applied to garden lamp.But since COB area light source belongs to list
Light source, power is big, and it is fast and more to generate heat, and the inner space of garden lamp is usually smaller, therefore is difficult such small
The heat of generation is discharged in time in space, to affect the service life of light efficiency and garden lamp.On the other hand, very much
The structure of the garden lamp in place is all columned lamp cap, and size is smaller, and the usual volume of radiator used in COB area light source
It is larger, therefore, transformation is realized in garden lamp being difficult to be directly embedded into, and use radiator similar with cylindrical lamp cap volume then
Often it is difficult to realize the heat conduction of COB area light source.
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.

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.
