Description
Technical field
The present invention relates to a kind of outdoor lamp, especially a kind of outdoor lamp that adopts led light source also relates to the LED street lamp, LED Square Lamp, LED garden lamp and the LED Tunnel Lamp that use this LED outdoor lamp simultaneously, belongs to technical field of lamps.
Background technology
Each state of the whole world is all wideling popularize the LED illumination at present, yet also fails to popularize at lighting field LED.This mainly is that technology is immature because of LED illumination cost height.But study carefully its more deeper reasons be that the heat dissipation problem of LED illumination also fails to solve well.We can find out the importance of LED heat radiation from the relation of LED temperature and its luminous efficiency: when the knot surface temperature rose to 100 ℃ by 25 ℃, its luminous efficiency will fail and 20% to 75% not wait, and was wherein serious with sodium yellow decline 75% again.In addition, when the operating environment temperature of LED is higher, its life-span is also lower, and when operating temperature was raised to 74 ℃ by 63 ℃, the LED average life span will reduce 3/4.Therefore, the heat dissipation problem of LED illumination has constituted the bottleneck that the LED illumination popularizes, and outdoor lighting is all the more so.
The existing technical literature about the heat radiation of LED light fixture of retrieval has:
One, the Chinese patent of the patent No. 200920112089.5 discloses a kind of high-power LED street lamp module of COB encapsulation, and this module comprises lens, silica gel, gold thread, chip, heat sink, and chip directly is fixed on the boss of heat sink.This module is installed to after outdoor lamp (as street lamp etc.) goes up, the heat that heat sink absorbs can't be passed to other places (such as lamp stand, lampshade or air etc.) rapidly, and protruding chain-wales has reduced heat-conducting area, unfavorable heat radiation, the therefore actual heat radiation that can not effectively finish led chip of this module.In addition, the technology that this module is made band boss heat sink is loaded down with trivial details, the cost height of packaging LED chips.
Two, the Chinese patent of application number 200710031038.5 discloses a kind of external radiator high-power LED street lamp fixture of being with, comprise light fitting main casing, lampshade, LED lamp, external radiator, power circuit system, light fitting main casing comprises that housing, heat pipe connector, LED lamp socket, heat pipe, radiating component constitute, one end of its light fitting main casing is provided with and is no less than one or one group of heat pipe and is connected in the LED lamp socket, and the other end of heat pipe connector is provided with and is no less than one or one group of heat pipe and is connected in external radiator.This LED light fixture is connected the LED lamp socket by heat pipe and carries out heat conduction with external radiator, but does not solve the problem how heat that LED produces passes to the LED lamp socket fast, and heat pipe can not directly be taken away the heat that LED produces fully; And adopt light fixture complex manufacturing technology, the cost of heat pipe too high, be difficult to popularization and application on general outdoor lamp.
Three, the Chinese patent of application number 200710028778.3 discloses a kind of lamp stem of high-power LED street lamp, is combined by lamp stand and radiator, is that lamp stand passes radiator or heat sink side and hangs over mode of connection on the lamp stand.This lamp stand has only been mentioned the lamp stand heat dissipation problem, and how the heat that not mentioned LED produces passes to lamp stand; And the indirect mode of connection of lamp stand and radiator also influences the rate of heat transfer and the efficient of lamp stand and radiator.
All there is such-and-such problem in above-mentioned exemplify existing more or less about LED light fixture heat dissipation technology, all fails thoroughly to solve the heat dissipation problem of outdoor LED light fixture, therefore still can't bring popularizing of outdoor LED light fixture.
Summary of the invention
The technical problem that the present invention solves is: the outdoor LED light fixture that proposes a kind of thorough solution outdoor LED light fixture heat dissipation problem.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of LED outdoor lamp, comprise lamp socket, lamp socket support member, LED driver module and be placed in LED on the lamp socket, described lamp socket and lamp socket support member are made integral heat sink device structure, be shaped on platform on the described lamp socket, described LED directly is encapsulated on the described platform.
Outdoor LED light fixture of the present invention, because creatively directly be encapsulated in LED on the lamp socket rather than be encapsulated in heat sink after refill on lamp socket, significantly reduced the too much intermediate link in the conduction of LED heat in the prior art, add the integral heat sink device structure of lamp socket, the heat that makes LED produce can directly distribute from this big radiator of lamp socket fast, thereby thoroughly solves the heat dissipation problem of LED light fixture.
What deserves to be mentioned is, the present invention directly is encapsulated in LED on the lamp socket and is not just can draw from prior art apparently before the present invention is open with the design that lamp socket and lamp socket support member are made integral heat sink device structure, especially LED directly is not encapsulated in the implementing process on the lamp socket in the prior art, has more limited the generation of this design.The inventor then broken through in the prior art separately and at lamp socket or lamp socket support member fragmentary radiator and LED to be set and directly not to be encapsulated in dual traditional thinking habit on the lamp socket, thereby opened up the directly lamp socket by having the large-area heat radiator structure and the lamp socket support member tactic pattern of dispelling the heat of LED.The then separate case description of technology that the LED that the inventor solved directly encapsulates at lamp socket.
Improvement of the technical scheme is: described LED is provided with reflection shield, described reflection shield have communicate with each other, large and small two-port that centering and area do not wait and connect cover body between the large and small two-port, described portlet be positioned at LED directly over and with the perimeter alignment of LED, the inner surface of described cover body is parabolic.
The inventor furthers investigate the back to LED heating mechanism and finds: (1) uses many adhesive (as epoxy resin or silica gel) during the outdoor lamp packaged LED at present, can form photic zone (epoxy resin layer or layer of silica gel) on the emission light outgoing circuit of LED behind these adhesive solidifications.Because these photic zones variations in refractive index everywhere is very big, LED emission light has quite a few can form repeatedly random scatters back and forth through photic zone the time, add the refractive index difference of LED itself, part light after the photic zone reflection is again through the irregular reflection of LED own, makes light consumption that quite a few LED sends in meaningless reflection and produce a large amount of heats.(2) emission of LED scattered light only, a plurality of LED emission light that get close to each other on the LED light fixture will form interference mutually, and the emission light that these interfere with each other will expend luminous energy and also produce heat energy simultaneously.Therefore in fact, the caloric value of LED have major part be very much come from LED emission light after through the meaningless reflection of photic zone luminous energy consumption and a plurality of LED emission light between the luminous energy consumption that interferes with each other.Based on this discovery, the inventor creatively is used in the reflector technology in the existing reflecting LED display screen, the one, make LED emission light interreflection no longer the time through photic zone, light is reflected out once being refracted on the reflection shield wall, the 2nd, each LED emission light can parallelly penetrate behind reflection shield, no longer forms between a plurality of LED emission light and interferes.Like this, both improved the utilization rate of light, reduced LED emission light again in a large number because the heat that luminous energy consumption is produced.
The inventor breaks through the fixed pattern thinking that tradition is distributed the LED caloric value simply, reverse consideration goes the LED caloric value is controlled, and successfully find the technological means that reduces the LED caloric value, thereby provide a kind of brand-new road for the thorough solution of outdoor LED light fixture heat dissipation problem.Need to prove, the reflection shield technological means of the present invention's utilization obviously is different from reflector technological means in the reflecting LED display screen, not only not easyly can expect, and the technical problem that is solved is also fully different with technique effect, therefore is that the creativeness of prior art is used.
Further improvement in the technical proposal is: described reflection shield adopts Heat Conduction Material to make, and its periphery place is equipped with the small heat-dissipating device.Like this, the LED emission heat that light produced can also distribute through reflection shield and small heat-dissipating device, further improves the heat-sinking capability of light fixture of the present invention.
The further improvement of technique scheme is: described parabola is a composite parabolic.Like this, LED emission light can change into directional light more to be launched, and further avoiding luminous energy consumption when improving the emission light utilization efficiency is that heat energy is to reduce the LED caloric value.
Further improving again of technique scheme is: the large port outside of described reflection shield is provided with concavees lens.Like this, LED emission light can form various shot shapes and coverage rate through behind the concavees lens again, thereby satisfies the lighting requirement in various actual places.
The perfect of technique scheme is: described LED and reflection shield are in alignment with each other and line up array, and described Heat Conduction Material is metal or pottery, and described small heat-dissipating device and LED reflection shield array are integrated, and the surface of described lamp socket and lamp socket support member scribbles soft ceramic coating.
First kind of technical scheme that the present invention releases on the technique scheme basis is: a kind of LED street lamp, comprise the LED outdoor lamp, and described lamp socket support member is a lamp stand.
