Description
Technical field
The present invention relates to LED luminaires, and in particular to a kind of unlimited direction COB LED luminescence components liquid-gas phase transition radiating
Module.
Background technology
LED illumination device development in recent years is very fast, and LED luminous efficiencies significantly improve, and caloric value substantially reduces, and uses
Life-span is also obviously improved, and radiating effect is the basic reason for influenceing its service life.In order to improve the installation of LED illumination device
Efficiency and diminution volume, COB LED encapsulation technologies are also arisen at the historic moment, and it is that multiple LED chip arrays are encapsulated in into one piece of substrate
On be made into high-power LED light emitting component, have the characteristics that high power density, high light flux, heat flow density are larger, with discrete peace
The LED of dress is compared, and because integration degree is high, power is big, small volume, caloric value is more concentrated, and its radiating effect influences its use
The problem of life-span, seems more prominent.The conventional radiating mode of COB LED luminescence components has many kinds at present, mainly there is nature pair
Flow heat dissipation, heat pipe auxiliary heat dissipation, fan forced convection radiating etc., these modes are entirely to pacify COB LED luminescence components substrate
Dress is radiated by radiator using above-mentioned various modes on a heat sink, is deposited between COB LED luminescence components substrates and radiator
In thermal contact resistance, thermal contact resistance can directly affect heat-transfer effect therebetween.In order to improve contact area therebetween, drop
Low thermal contact resistance, the thermal interfacial materials such as heat-conducting silicone grease can be smeared between COB LED luminescence components substrates and the contact surface of radiator,
But the thermal conductivity factor of thermal interfacial material had both been less than COB LED luminescence components baseplate material, again smaller than radiator material, hot interface material
Expect to be much smaller than the heat conduction along the hot interface direction of thermal interfacial material in the thermal conductivity factor from COB LED luminescence components substrates to radiator
Coefficient.Even if therefore having smeared thermal interfacial material, the thermal contact resistance between COB LED luminescence components substrates and radiator is also basic
It can not eliminate, with the increase of usage time, thermal interfacial material long-term heated rear and COB LED luminescence components substrates and radiator
Between contact effect can be gradually reduced, thermal resistance can also further increase, further influence from COB LED luminescence components substrates to
The heat-transfer effect of radiator.
The LED luminescence components of conventional single-chip package are not because caloric value concentrates, caloric value is small, relatively easily by heat
Amount is conducted and is diffused into environment.And high-power COB LED luminescence components due to caloric value concentrate, caloric value it is big, with greater need for
Efficiently quickly by heat transfer and export, otherwise self-heating effect will be produced on COB LED luminescence component substrates, be formed
Thermal accumlation temperature more and more higher, if temperature will result directly in COB more than COB LED luminescence component use temperature upper limits
LED luminescence components luminous efficiency, which reduces, even to be damaged, and destructive shadow is brought to the Performance And Reliability of COB LED luminescence components
Ring, and substantially reduce its service life, turn into the technical bottleneck of popularization and application COB LED illumination products.
In addition, limited currently with the COB LED luminescence components of heat pipe auxiliary heat dissipation by installation direction, it is impossible to by COB
LED luminescence components are installed along any direction, very big using being limited, also can not wide popularization and application.
The content of the invention
The purpose of the present invention is obvious thermal contact resistance be present for existing COB LED luminescence component radiating modes, is not allowed
Easily heat is exported in time, easily produces thermal accumlation superposition, radiating effect is undesirable, has a strong impact on service life, uses peace
A kind of the defects of dress is limited by direction, there is provided unlimited efficient COB LED luminescence components liquid-gas phase transition radiating module in direction.
The present invention technical solution be：It includes COB LED luminescence components and module housing, module housing be provided with
The closed ducted body of luminescence component installing port, the periphery of COB LED luminescence component substrates are directly or indirectly sealingly mounted at module
On luminescence component installing port on housing, closed heat exchanging chamber, COB LED hairs are surrounded in module housing together with module housing
The light-emitting area of optical assembly is towards outside module housing, and the substrate backs of COB LED luminescence component light-emitting area dorsal parts is towards module housing
The evaporating surface of Inner Constitution heat exchanging chamber, the inwall of module housing form the cryosurface of heat exchanging chamber, and heat exchanging chamber inside points are filled with work
Make liquid, be provided with heat exchanging chamber and be close to COB LED luminescence components towards on the substrate back in heat exchanging chamber and extending and be close to
Loose structure capillary wick on module housing inwall, loose structure capillary wick form the work from condensation towards evaporating surface
Make liquid capillary force return flow line, the clearance position in heat exchanging chamber outside loose structure capillary wick is formed from evaporating surface to cold
The hydraulic fluid steam channel in solidifying face.
The solution have the advantages that：It eliminates thermal interface material, effectively reduces conventional COB LED luminescence components and dissipates
Thermal contact resistance in thermal process, its caused heat rapidly can be transmitted and exported in time, self-heating situation will not be formed,
Thermal accumlation will not be caused to be superimposed, the radiating effect of COB LED luminescence components is reached idealization, its use can be greatly improved
Life-span, performance and reliability are also greatly improved, and overcome that radiating effect is not good enough to have a strong impact on popularization and application
Defect.
Do not limited in its use by direction, can be installed and used by any direction, further increase application, be big
The popularization and application of power COB LED luminescence components provide sound assurance.It becomes by inside modules hydraulic fluid vapour, liquid phase
Directly the heat transfer in COB LED-baseplates to radiator, hydraulic fluid are directly contacted with COB LED luminescence components substrates,
Thermal interfacial material is eliminated, considerably reduces the thermal contact resistance between COB LED-baseplates and thermal component, can be timely and effective
Heat at COB LED luminescence component substrate base thermals source is delivered to outside thermal source rapidly.In liquid-gas phase transition diabatic process, thermal resistance is very
Small, heat-transfer effect is more reliable, and heat-transfer capability is stronger, more efficient, and reached rapidly and efficiently reduces COB LED luminescence components in time
The purpose of substrate temperature.
It is simple in construction, is conducted heat by hydraulic fluid itself liquid-gas phase transition, it is not necessary to expends other energy auxiliary and passes
Heat, use cost are lower.It can reduce process costs, realize standardization and industrialized production, also led for other high-power halfs
The high efficiency and heat radiation of body device provides a preferable approach.
Advantages of the present invention：
1st, COB LED luminescence components substrate be directly in contact with hydraulic fluid liquid-gas phase transition radiating, eliminate thermal interfacial material；
2nd, COB LED luminescence components substrate be directly in contact with hydraulic fluid liquid-gas phase transition radiating, change heat transfer type, significantly
