Description
Technical field
The utility model is related to LED lamp, more particularly to a kind of direct heat-dissipating LED lamp of liquid.
Background technology
In recent years, based on energy-conserving and environment-protective, efficiency high, small size, longlife noodles the features such as, LED is increasingly by consumer
Favor.But radiator of the prior art uses metal heat sink mostly, metal heat sink cost itself is higher, and itself is also
Ultrasonic many heats, directly affect the life-span of LED lamp.
The liquid that presently, there are mainly has three kinds of structures with regard to direct radiating LED lamp：Direct liquid submersion, liquid leaching
Do not combine metal fins radiator and indirect immersion.Mainly there is metal heat sink for liquid-immersed combination metal heat sink
Built-in and external two kinds, external heat radiation structure is better than built-in, but not only cost is high for two kinds of structures, and structure is also all complicated, close
The poor reliability of envelope, liquid is easily revealed.Indirect immersion is mainly using transparent sealed cover is by LED lamp bead and aluminium base and dissipates
Hydrothermal solution is isolated, and thus relaxes the range of choice of cooling fluid.For the unshielded structure of LED/light source, the selection bar of cooling fluid
Part it is harsher, it is necessary to meet good insulating, light transmittance height, non-corrosiveness, do not react with lamp interior material, physics and
Chemical property stabilization etc. is required.And direct immersion LED lamp, simple in construction, perfect heat-dissipating, cost is low, as the cold side of liquid
The first choice of formula.
Utility model content
The defect for aiming to overcome that prior art of the present utility model, according to the development trend of current light fixture there is provided
A kind of direct heat-dissipating LED lamp of liquid, including power supply, shell, air layer, cooling fluid, electrode, MCPCB substrates, LED/light source.
The cooling fluid is silicone oil, and the LED/light source outside is fixed on described MCPCB with silica gel packaging and by scolding tin
Substantially, the LED/light source complete wetting is in the cooling fluid, and the bipolar electrode provides the LED/light source and the voltage
Electrode connect and support LED/light source, the air layer, which is used to alleviating liquid, to expand with heat and contract with cold caused Volume Changes, the shell
For glass shell, it is packaged outside the light fixture with the shell, constitutes the LED lamp of the direct heat radiating type of liquid.
Preferably, the LED/light source is GaN high-power LED chips.
Preferably, the material of the electrode is copper.
The beneficial effects of the utility model are：LED lamp uses the direct heat dissipation technology of liquid, and metal is eliminated in structure and is dissipated
Hot device and heat conduction colloid, and the medium that the higher liquid silicone oil of heat dispersion is exchanged with the external world is employed, what heat conduction resistance reduced
Also cause fitting structure simple simultaneously, price reduction, meanwhile, silicone oil is a kind of poly organo of different polymerization degree chain structure
Alkane, colorless and odorless transparency liquid, the viscous coefficient of temperature is small, high-low temperature resistant, anti-oxidant, flash-point are high, insulating properties is good, and volatility is small and nontoxic
Free from corrosion characteristic so that the cooling fluid that silicone oil is more suitable for doing LED lamp is used.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description, embodiment is only this reality
With new one embodiment, for those of ordinary skill in the art, without having to pay creative labor, go back
