Description
Technical field
The utility model relates to a kind of lighting device, especially relates to a kind of large power heat pipe LED lighting device.
Background technology
The at present domestic lighting apparatus that generally adopts has four kinds of incandescent lamp, fluorescent lamp, high-intensity gas discharge lamp and LEDs.Wherein incandescent lamp, fluorescent lamp, high-intensity gas discharge lamp power consumption are high, and service life is short, is unfavorable for environmental protection.Comparatively speaking, the LED lighting apparatus has advantages such as volume is little, power consumption is low, long service life, high brightness.The energy conversion rate of LED is quite high, and its power consumption is 10% of conventional incandescent under the equal in theory brightness.As the LED lighting apparatus being widely used in the public lighting, to compare with the general lighting equipment of existing use, will save 90% power consumption every year.But great power LED is responsive to temperature rise ratio, so solve the heat dissipation problem of great power LED, assurance great power LED reliability service at a lower temperature is a subject matter of extensively carrying out the required solution of high-power LED (light emitting diode) lighting equipment.
Chinese invention patent application 200710102800.4 discloses a kind of pipe cooled superhigh power LED lamp and manufacture method thereof, and the structure of this LED lamp mainly is connected to substrate by LED Lamp cup body, and substrate is connected to metallic plate, and metallic plate is connected to heat pipe and constitutes.This LED lamp mainly is the heat that discharges when utilizing heat pipe to absorb LED work.Though this technical scheme can solve the heat dissipation problem of LED lamp to a certain extent, and fail to solve effectively the heat dissipation problem of heat pipe self.Temperature raise rapidly after heat pipe had absorbed the heat that LED discharges, if can not be in time, efficiently the heat of heat pipe self is distributed, will influence the further absorption of heat pipe to the LED heat.Simultaneously, caloric requirement between pedestal and the heat pipe is through the transmission of metallic plate, and this makes the capacity of heat transmission between pedestal and the heat pipe weaken relatively, and makes whole lighting apparatus complex structure.
The utility model content
The purpose of this utility model is to provide a kind of heat pipe two ends to connect pedestal and heat abstractor respectively for solving above-mentioned the deficiencies in the prior art part, make the heat pipe can be the heat transferred heat abstractor that from pedestal, directly absorbs, pilot process that heat transmits, the better large power heat pipe LED of simple in structure, radiating effect lighting device have been shortened.
The purpose of this utility model is achieved through the following technical solutions: large power heat pipe LED lighting device, include LED, pedestal, heat pipe and heat abstractor, one side of described pedestal is provided with one or more than one LED, and an end of described heat pipe is connected with described pedestal, the other end is connected with described heat abstractor.
Described heat pipe can be U-shaped heat pipe and/or L shaped heat pipe.Its quantity can be provided with more than one or one as required.
Described heat abstractor is made of fin.
One side of described pedestal offers the notch that matches with the LED size, the rectangular or annular spread of described notch.
Described pedestal can be the pedestal of being made by higher copper of thermal conductivity factor or aluminium, and its shape can be a kind of shape in circular, ellipse or the rectangle.
Being welded to connect or filling heat-conducting silicone grease between described heat pipe and the pedestal is connected.
Described pedestal is provided with groove structure, and an end of described heat pipe is arranged in the described groove, and described groove number is corresponding with described heat pipe quantity.
Described pedestal is provided with through-hole structure, and an end of described heat pipe is arranged in the described through hole, and described number of openings is corresponding with described heat pipe quantity.
In large power heat pipe LED lighting device of the present utility model, the heat that produces during great power LED work is delivered on the pedestal.Because heat pipe one end directly is connected pedestal, so heat pipe can directly absorb heat from pedestal, simultaneously heat in time is delivered to heat abstractor, by heat abstractor to outside distribute heat.Directly welding or fill heat-conducting silicone grease and need not heat transfer medium in the middle of other between heat pipe and the pedestal, thermal resistance is less relatively, and heat transfer efficiency is higher.The heat that heat abstractor has quickened heat pipe self distributes, and has reduced the temperature of heat pipe, makes heat pipe can more, more effectively absorb the heat of LED and power supply changeover device work release, thereby guarantees LED reliably working at a lower temperature.
The utility model compared with prior art has simple in structure, can solve the heat dissipation problem of heat pipe well, guarantees the characteristics of the operate as normal of LED.

The specific embodiment
As shown in Figure 1, the embodiment of large power heat pipe LED lighting device of the present utility model includes fin 1, lampshade 2, pedestal 3, great power LED 4 (formations such as power 〉=1W) and heat pipe 5.
A plurality of great power LEDs 4 are arranged at the downside of pedestal 3, and as shown in Figure 4, the downside of pedestal 3 offers the notch that matches with great power LED 4 sizes, and great power LED 4 can be in the form of a ring or rectangular-shaped distribution.One end of heat pipe 5 links to each other with pedestal 3, the other end links to each other with fin 1.
Be provided with many heat pipes 5 in the present embodiment, and heat pipe 5 can be L shaped and/or take the shape of the letter U.
Described heat pipe 5 can directly be welded to connect or fill heat-conducting silicone grease with pedestal 3 and be connected.
In the present embodiment, the upside of pedestal 3 is a groove structure, and an end of heat pipe 5 is arranged in the groove, and every heat pipe 5 correspondence are arranged in one groove.
As shown in Figure 3, in other embodiments, the upside of pedestal 3 also can be set to through-hole structure, and an end of heat pipe 5 is arranged in the through hole, and number of openings is corresponding with heat pipe 5 quantity respectively.
The heat that produces during great power LED 4 work is delivered on the pedestal 3.Because heat pipe 5 one ends directly are connected on the pedestal 3,, simultaneously heat in time is delivered on the fin 1, by fin 1 outside distribute heat so heat pipe 5 can directly absorb heat from pedestal 3.Directly welding or fill heat-conducting silicone grease and need not have heat transfer medium in the middle of other between heat pipe 5 and the pedestal 3, thermal resistance is less relatively, the heat transfer efficiency height.Fin 1 helps heat pipe 5 to quicken distribute heat, reduces the temperature of heat pipe 5, the heat that discharges when making heat pipe 5 can more, more effectively absorb the work of great power LED 4 and power supply changeover device, thus guarantee great power LED 4 reliably working at a lower temperature.Lampshade 2 can play a protective role, and avoids the utility model to be subjected to erosion by wind and rain in the open during user mode.The utility model is simple in structure, can solve the heat dissipation problem of heat pipe effectively, guarantees the operate as normal of LED.
Should be noted that at last; above embodiment only illustrates the technical solution of the utility model but not to the restriction of the utility model protection domain; although the utility model has been done detailed description with reference to preferred embodiment; those of ordinary skill in the art tackles understanding; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
