Description
Technical field
The utility model is related to a kind of LED lamp, specifically a kind of to expand heat-dissipating LED lamp.
Background technology
LED lamp is high with its luminous efficiency, lights without stroboscopic, full the advantages of color reduction degree is high to human eye non-hazardous
Ball is known as 21 century newest lighting.But its caloric value is huge, heat problem high is brought to production and application, current is high-power
LED lamp is main or improves radiating effect by blindness increasing radiator, and this method cost is obvious, while also causing it
Volume is too fat to move, and weight is larger, is that the installation of light fixture causes many inconvenience, how radiating effect is improved on the premise of volume is simplified
Really, while reduce cost input improves extremely important for the production of LED lamp.
Utility model content
The purpose of this utility model is to provide a kind of expansion heat-dissipating LED lamp, to solve to be proposed in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：
One kind expands heat-dissipating LED lamp, including lampshade and substrate, and the substrate is fixedly mounted on lampshade bosom position
Put, substrate lower end is fixedly connected with some LED chips, the substrate back is fixedly connected with some radiating aluminium sheets, radiating aluminium sheet
In four groups of sectors of independence, every group of fan-shaped group upper end has been fixedly connected with heat sink, and heat sink end is embedded with fixation for arrangement
Radiating block in lampshade upper end is fixedly connected, and substrate back is also fixedly connected with some U-shaped heat conduction bars, U-shaped heat conduction bar and radiating
Aluminium flake is staggered, and the U-shaped heat conduction bar other end both passes through lampshade bottom plate and exposes, during the heat sink and U-shaped heat conduction bar are
Hollow structure and it is internal be negative pressure state, heat sink and U-shaped heat conduction bar inwall is covered with cotton-shaped liquid-sucking core and inside is filled with
Acetone, the radiating aluminium sheet, heat sink, U-shaped heat conduction bar and heat dissipation block surface and substrate back are coated with a nanometer heat radiation coating,
Lampshade side wall is further opened with some air vents.
As further program of the utility model：The nanometer heat radiation coating is water-based cooling coating.
Compared with prior art, the beneficial effects of the utility model are：Increase infra-red radiation by nanometer heat radiation coating to imitate
Rate, the overall heat conduction efficiency of lifting lamp interior, does not contact, inner air circulation between heat sink and U-shaped heat conduction bar
Good, while coordinating the heat sink and U-shaped heat conduction bar of liquid heat pipe principle by internal heat Quick diffusing to the external world, effectively lifting is existing
There is the heat dispersion of single aluminium block radiating, while without precious metal input, cost increases small.
Brief description of the drawings
Fig. 1 is a kind of structural representation for expanding heat-dissipating LED lamp.
Fig. 2 is a kind of overlooking the structure diagram for expanding heat-dissipating LED lamp.
Fig. 3 is a kind of structural representation for expanding heat sink in heat-dissipating LED lamp.
Specific embodiment
The technical scheme of this patent is described in more detail with reference to specific embodiment.
Fig. 1-3 are referred to, one kind expands heat-dissipating LED lamp, including lampshade 1 and substrate 2, and the substrate 2 is fixedly mounted on
The bosom position of lampshade 1, the lower end of substrate 2 is fixedly connected with some LED chips, and the back side of the substrate 2 is fixedly connected with some
Radiating aluminium sheet 3, in four groups of sectors of independence, every group of fan-shaped group upper end has been fixedly connected with heat sink 4 to the arrangement of radiating aluminium sheet 3, dissipates
The radiating block 5 that the end of hot plate 4 is embedded in the upper end of lampshade 1 with fixation is fixedly connected, and the back side of substrate 2 is also fixedly connected with some U
Shape heat conduction bar 6, U-shaped heat conduction bar 6 is staggered with radiating aluminium sheet 3, and the other end of U-shaped heat conduction bar 6 both passes through the bottom plate of lampshade 1 dew
Go out, do not contacted between radiating aluminium sheet 3 and U-shaped heat conduction bar 6, lift inner air circulation, the heat sink 4 and U-shaped heat conduction bar 6
Be hollow structure and it is internal be negative pressure state, heat sink 4 and the inwall of U-shaped heat conduction bar 6 are covered with cotton-shaped liquid-sucking core 7 and interior
Portion is filled with acetone, and using liquid heat pipe principle, the acetone boiling point under internal negative pressure state is extremely low, and acetone is in the He of absorptive substrate 2
Evaporation endothermic after heat on radiating aluminium sheet 3, acetone steam carrier amount of heat toward the relatively low outer side shifting of temperature, by heat
Rear acetone steam is condensed into liquid again in being delivered to outside air, and backflow is laid equal stress on and newly steam under the capillary force effect of liquid-sucking core 7
Hair heat absorption, it is and so on, described in cost substantially without the heat-conductive characteristic that internal heat-conducting piece is effectively increased in the case of increased
Radiating aluminium sheet 3, heat sink 4, U-shaped heat conduction bar 6 and the surface of radiating block 5 and the back side of substrate 2 are coated with a nanometer heat radiation coating, nanometer
Heat radiation coating is water-based cooling coating, and environmental protection is inexpensive, by improving infrared radiation efficiency, reducing superficial air flow damping coefficient
Etc. mode improving radiating effect, coordinating the heat sink 4 and U-shaped heat conduction bar 6 of liquid heat pipe principle quickly can distribute heat,
The side wall of the lampshade 1 is further opened with some air vents 8, it is ensured that inner ventilation, the simple small volume of overall structure, and cost increases few,
Radiating effect is effectively lifted.
The better embodiment to this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, in the ken that one skilled in the relevant art possesses, can also be on the premise of this patent objective not be departed from
Make a variety of changes.
