Description
Technical field
The utility model relates to a kind of LED of improvement, and particularly a kind of swabbing effect utilizing air to flow carries out the LED of dispelling the heat, and belongs to lighting technical field.
Background technology
LED has been obtained has widely used with its energy-saving and environmental protection, the feature such as efficient, but, because LED is semiconductor photoelectric device, its caloric requirement of distributing excludes effectively, otherwise PN junction can be caused to heat up, thus causing light to lead to exhaustion, efficiency reduces, and LED also can be caused time serious to damage.Therefore, how effectively to solve the problem of LED heat radiation, be the emphasis that insider studies always.At present, be that single-point or the LED street lamp of multi-point source all also exist the difficult problem of heat radiation.To other light source; such as 250W high-pressure mercury lamp; even if work 5000 hours; its light decay is still less, and luminous efficiency still can reach 70%, and by contrast; high-powered LED lamp under the same conditions; because heat dissipation problem not easily solves, its light decay wants large many, and luminous efficiency can drop to 30% usually.If the method passing through high voltage electric current by force improves light efficiency, be easy to the consequence causing LED chip to damage.So, be badly in need of in the industry a kind of method that can solve the problem such as the heat radiation that occurs and light decay when high-powered LED lamp uses.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of structure simple, the LED with great heat radiation effect that is convenient and that can effectively prevent LED overheated is installed.
Problem described in the utility model solves by the following technical programs:
There is a LED for great heat radiation effect, the drawing and heat dissipation part that it comprises LED body, radiator and is made up of vertical air channel, connection air channel and heat radiation chamber; The one end in described connection air channel is communicated with vertical air channel, the other end and heat radiation chamber; Described heat radiation chamber is oblique is arranged on the one end being communicated with air channel, and namely LED body is arranged on the end face of heat radiation chamber, and described LED body is fixing on a heat sink; Described radiator is provided with fin; Described vertical air channel is through tubular construction.
The above-mentioned LED with great heat radiation effect, sets up side air admission mouth; Described side air admission mouth is multiple, is distributed on the periphery of radiator.
The above-mentioned LED with great heat radiation effect, described LED body sets up multiple secondary ventilation hole, arranges multiple air vent communicated with it on a heat sink simultaneously.
The above-mentioned LED with great heat radiation effect, sets up heat-conducting silicone grease, and described heat-conducting silicone grease is arranged between radiator and LED body.
The above-mentioned LED with great heat radiation effect, the bottom in described vertical air channel is provided with main air inlet.
The utility model utilizes vertical air channel, is communicated with the drawing and heat dissipation part of air channel and heat radiation chamber composition, chimney principle and LED are integrally combined, efficiently solve the heat dissipation problem of LED, prevent because LED heat radiation not in time and the luminous efficiency that causes reduces and the problem such as damage.And, for long-pending water problem occurs when meeting sleety weather prevention radiator portion, therefore connection air channel and heat radiation chamber being designed in an inclined manner, preventing the generation of inner product regimen condition with this.In addition, the utility model is provided with heat-conducting silicone grease between radiator and LED, effectively can strengthen the heat conductivity between radiator and LED.The utility model structure is simple, and it is convenient to install, perfect heat-dissipating, is very suitable for installing and using in the occasion of street lamp, threshing ground lamp etc.
Accompanying drawing explanation
Fig. 1 is structural representation profile of the present utility model;
Fig. 2 is that the K of Fig. 1 is to partial schematic diagram.
In figure, each list of reference numerals is: 1. vertical air channel, 2. connection air channel, 3. heat radiation chamber, 4.LED lamp body, 5. heat-conducting silicone grease, 6. side air admission mouth, 7. fin, 8. radiator, 9. main air inlet, 10. secondary ventilation hole.
Detailed description of the invention
Referring to Fig. 1 and 2, the drawing and heat dissipation part that the utility model comprises LED body 4, radiator 8 and is made up of vertical air channel 1, connection air channel 2 and heat radiation chamber 3; Described drawing and heat dissipation part is the principle work utilizing " stack effect ", and namely when the temperature outer higher than chimney of temperature in vertical air channel, the hot-air in vertical air channel is little because of density, just along naturally rising, flows out from the top in vertical air channel; Cold air outside Vertical Channel is large because of density, is infiltrated and supplements, thus reach the object of heat radiation by bottom.Prove that vertical air channel is higher through test, effect is also more obvious.The annexation of described drawing and heat dissipation part is: the top in described vertical air channel 1 is hatch frame, is provided with main air inlet 9 bottom it; The one end in described connection air channel 2 is communicated with vertical air channel 1, and the other end is communicated with heat radiation chamber 3; Oblique being arranged on of described heat radiation chamber 3 is communicated with on air channel 2, and the other end and LED body 4 are fixed, and described heat radiation chamber 3 inside is provided with the radiator 8 be connected with LED body 4; The other end of described radiator 8 is provided with fin 7, and described fin 7 is aluminum products.
For strengthening thermal diffusivity, the utility model spy sets up side air admission mouth 6; Described side air admission mouth 6 is multiple setting, is distributed on radiator 8, for accelerating fin heat radiation.Described radiator is copper product.In addition, the utility model has set up multiple secondary ventilation hole 10 too on LED body 4, and on heat sink, is provided with the air vent communicated with it simultaneously.The shape of described secondary ventilation hole 10 and side air admission mouth can be the shape such as circle or rectangle, and its optimum shape is rectangle; The optimal height of described secondary ventilation hole 10 and side air admission mouth is 70mm.
The novel heat conductivity for strengthening between LED body 4 and radiator of this practicality, spy sets up heat-conducting silicone grease 5, and described heat-conducting silicone grease 5 is arranged between radiator 8 and LED body 4, can effectively improve heat conductivity between radiator 8 and LED body 4.
