Background technology
Energy-conserving and environment-protective in recent years; Start the fundamental policies that low-carbon (LC) society has become countries in the world; Led light source has demonstrated the unrivaled good characteristic of conventional light source as the new generation of green lighting source aspect energy-saving and environmental protection, be widely used in road, square, occasion such as indoor.
LED is as cold light source, and about 20% energy can be converted into light, and residue 80% energy is that the form with heat energy distributes, and along with the use of LED lamp, temperature can increase, and in order to let the LED operate as normal, heat radiation just becomes the difficult problem that must solve.Generally adopt at present the method for radiator to realize heat radiation: in outdoor lighting, generally the volume to lamp does not have strict requirement, and it is bigger that radiator can be done, and can realize heat radiation faster, and the power of LED lamp can do very big; With respect to outdoor use LED lamp; Indoor just have higher requirement for its volume and attractive in appearance; What so just cause that the volume of radiator can not do is very big; Radiating rate is fast inadequately, and power does not increase yet, even add that active heat removal also is difficult to accomplish increase its radiating rate not increasing under lamp body volume and the situation attractive in appearance.
Summary of the invention
The objective of the invention is in order to overcome the prior art deficiency, a kind of LED lamp with main duct to wandering heat dissipation channel is provided.
The objective of the invention is to realize through following technical scheme: a kind of have a duct formula heat loss through convection LED channels lamp, and it comprises lamp holder, heat radiation lamp body, led light source, luminous intensity distribution lampshade, dividing plate and drive circuit; Wherein, the heat radiation lamp body is hollow and annular, and the upper end is connected with lamp holder; Drive circuit is positioned at the cavity of being made up of heat radiation lamp body, lamp holder and dividing plate, and an end connects lamp holder, and the other end connects led light source; Led light source is distributed in the Heat radiation lamp holder bottom ringwise, and covers sealing by the luminous intensity distribution lampshade; Be provided with endoporus and some passages that link to each other with endoporus in the described Heat radiation lamp holder; Passage is communicated with endoporus and Heat radiation lamp holder outer surface, and bore area is provided with interior radiating fin, and the Heat radiation lamp holder outer surface is provided with outer radiating fin; The luminous intensity distribution lampshade ringwise, the centre has an outer hole; Outer hole is communicated with duct of formation with endoporus, duct communicates with passage and forms the heat loss through convection passage.
Further, also comprise a fan, fan is installed in the interior radiating fin top of endoporus, and links to each other with drive circuit.
The invention has the beneficial effects as follows; The present invention in the indoor design of LED a kind of duct; This duct can form stack effect and can strengthen the convection current of air and increase area of dissipation, separates heat radiation simultaneously to led light source part and circuit control section simultaneously, has effectively promoted the heat-sinking capability of LED.The present invention can increase a radiating electric fan simultaneously in duct, further strengthened the cross-ventilation heat dissipation capability, for small size, high-power active heat removal LED lamp provide a kind of possibility later on.

The specific embodiment
Describe the present invention in detail according to accompanying drawing and embodiment below, it is more obvious that the object of the invention and effect will become.
Embodiment 1
As shown in Figure 1, the present invention has duct formula heat loss through convection LED channels lamp, comprises lamp holder 1, heat radiation lamp body 2, led light source 5, luminous intensity distribution lampshade 6, dividing plate 11 and drive circuit 12; Heat radiation lamp body 2 is hollow and annular, and the upper end is connected with lamp holder 1; Heat radiation lamp body 2, lamp holder 1 and dividing plate 11 form a cavity, and drive circuit 12 is positioned at this cavity, and an end connects lamp holder 1, and the other end connects led light source 5; Led light source 5 is distributed in Heat radiation lamp holder 2 bottoms ringwise, and covers sealing by luminous intensity distribution lampshade 6.
Described Heat radiation lamp holder 2 is processed by metal, plastics etc., in be provided with endoporus 3 and some passages 4 that link to each other with endoporus 3; Passage 4 is communicated with endoporus 3 and Heat radiation lamp holder 2 outer surfaces, and endoporus 3 surfaces are provided with interior radiating fin 8, and Heat radiation lamp holder 2 outer surfaces are provided with outer radiating fin 9.
Described luminous intensity distribution lampshade 6 is a kind of even light modulation cover or light-distribution lens of being processed by optical material, and ringwise, the centre has an outer hole 7.
Described outer hole 7 is communicated with duct of formation with endoporus 3, duct communicates with passage 4 and forms the heat loss through convection passage.
As shown in Figure 2, the duct of being made up of endoporus 3 and outer hole 7 is positioned at heat radiation lamp body 2 and luminous intensity distribution lampshade 6 centers, the overwhelming majority of passing whole luminous intensity distribution lampshade 6 and heat radiation lamp body 2; And be connected with all side passages 4, light fixture in use, natural convection air forms stack effect in duct and passage 4; Stack effect is meant, after air in the duct is heated intensification, rises along duct; And leave through passage 4, the duct internal gas pressure reduces, and makes air outside outer hole 7, get into and replenishes; More make air flow faster in the duct, quicken the lamp body heat radiation.
As shown in Figure 3, the difference of the structure of this embodiment and embodiment 1 is, on interior radiating fin 8 tops of endoporus 3 fan 10 is installed, and fan 10 links to each other with drive circuit 12.The air that fan 10 can greatly quicken in the duct flows, thereby can quicken heat radiation, and does not increase the volume of LED lamp.Among this embodiment, the matching design of fan 10 and duct can realize the LED lamp that the volume small-power is big.
As shown in Figure 4, the present invention is outside heat radiation lamp body 2 is provided with in the radiating fin 9, and radiating fin 8 in also in endoporus 3, being provided with along hole wall has increased area of dissipation, and is helpful to fan attachment 10 simultaneously.Luminous intensity distribution lampshade 6 adopts the annular surface design, and uses even light design such as frosted, pad pasting, and finally evenly bright dipping goes out wide-angle and can reach about 180 degree.7 porch, outer hole are not straight from inside to outside; But certain radian is arranged; Such design can avoid because curvature mutation to the inconvenience that brings on the luminous intensity distribution, soft is excessively more attractive in appearance, and can not see that in light fixture work there are black circle and black hole in luminous intensity distribution lampshade 6 centers.
The luminous intensity distribution design that the present invention is soft, unique heat radiation tolerance range that reaches than large span provides a kind of possibility for indoor than high-power LED lamp.
