The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, further set forth advantage of the present utility model.
Consulting Fig. 1, is the profile of LED lighting 100 in the utility model one preferred embodiment.In the utility model, LED lighting 100 has comprised cover body 110 and pedestal 120, and cover body 110 is connected to each other with pedestal 120, has formed the body of LED lighting 100.Wherein cover body 110 can be regarded as the diffuser of the light that transmitted light source 140 sends or for holding the cover body 110 of power supply; also or the protective cover of protection LED lighting 100 inner parts; and pedestal 120 is for carrying the base of the necessary illuminace components such as light source 140, power supply 150.At cover body 110 and 120 of pedestals, be provided with a support 130, by the light source in cover body 110 140 or power supply 150 supports.Conventionally known, partial illumination light fixture 100 is located at light source 140 in light fixture top, to top or the place ahead of light fixture, sends illumination, and the lighting 100 of another part is located at light source 140 in light fixture middle part, to the surrounding of light fixture, sends illumination.In this case, power supply 150 can be arranged in the top of light fixture, to save the space of whole lighting 100.The setting of this support 130, the body of the LED lighting 100 that cover body 110 and pedestal 120 are formed is separated into for two parts, the part that its medium-height trestle 130 and cover body are 110 is for holding the above-mentioned light source of mentioning 140 or power supply 150, and 120 of support 130 and pedestals form a cavity 122, light source 140 (power supply 150 is located in the situation of 110 of support 130 and cover bodies), light source board, radiator etc. can be set in this cavity 122, and pedestal 120 lower ends also connect a lamp holder, as the connector with socket.Usually, on cover body 110, offer a plurality of louvres 111, when lighting 100 is used, the light source 140 in cover body 110 or power supply 150 evolutions of heat, and part is discharged by this louvre 111.Because this louvre 111 is through hole, when the louvre 111 of these through hole types is not while arranging in correspondence with each other, do not there is cross-ventilated effect; When louvre 111 parts of these through hole types arrange in correspondence with each other, only the air on top can carry out convection current with extraneous air, therefore it is only used as: behind the space in hot-air is filled cover body 110, a large amount of hot-airs cannot be accommodated in cover body 110 when interior again, just can discharge by this louvre 111.Thereby, on the pedestal 120 of this LED lighting 100, also offer at least one first through hole 121, by the air communication outside the cavity of 130, pedestal 120 and support 122 and pedestal 120, under such configuration, when these cavity 122 interior settings be light source 140 time, the heat that this light source 140 produces can be expelled to outside light fixture by this first through hole 121.Simultaneously, on support 130, offered at least one second through hole 131, the air that this second through hole 131 connects in cavity 122 and cover body 110, thereby the air in cavity 122 and cover body 110 can convection current, and all can hot-air be discharged or be exchanged with extraneous air by louvre 111 and the first through hole 121.Moreover, because the first through hole 121 is different from the setting position of louvre 111, space in whole LED lighting 100 is got through by above-mentioned the first through hole 121 and louvre 111, the first through hole 121, cavity 122, the second through hole 131, louvre 111 form a ventilating path, the first through hole 121 and louvre 111 can be considered as respectively two openings of this ventilating path, by this ventilating path, this LED lighting 100 has a ventilating duct, naturally its radiating effect also just improves thereupon.
Consulting Fig. 2, is LED lighting 100 external structure schematic diagrames in the utility model one preferred embodiment.In this embodiment, louvre 111 is arranged on to cover body 110 away from the end of support 130, i.e. the top of cover body 110, each first through hole 121 is arranged on pedestal 120 away from the end of support 130, be the bottom of pedestal 120, thus the distance of 121 of louvre 111 and the first through holes maximized.Well known to those skilled in the art, when the air containment of participation convection current is larger, when flow velocity is faster, the effect of heat loss through convection is also just better.When the distance of 121 of louvre 111 and the first through holes is increased, the radical length of ventilating path also correspondingly increases, the volume of air that this ventilating path comprises is also just larger, simultaneously, because hot-air is always to rising, hot-air in this ventilating path longer distance of need to advancing just can flow to outside lighting 100, the flow velocity of these hot-airs in ventilating path is also increasing under certain acceleration, when affecting two factors of convection effects and increase substantially simultaneously, the radiating effect of this LED lighting 100 has correspondingly also improved significantly.
Continue to consult Fig. 2, more preferably, the first through hole 121 rings are located on pedestal 120, and the horizontal level of each the first through hole 121 is all identical, and the first through hole 121 is in the same level of pedestal 120.The benefit of configuration is like this: flow velocity when extraneous air flows into the first through hole 121 is identical, for the convection effects of the various piece of the air in cavity 122 also by identical, simultaneously preferred or optional, the spacing that each first through hole is 121 all equates, the air capacity that in the vertical direction plays convection effects is also by identical, can not cause the air velocity of a side in cavity 122 comparatively fast to be discharged in a large number, and the slow a small amount of situation of discharging of the air velocity of another survey has played the effect of homogenising heat-dissipating cavity 122 interior air.
Based on above-mentioned consideration, the second through hole 131 also can be set to ring and be located at the end face of support 130, and preferably or alternatively, the spacing that each second through hole is 131 all equates, carrys out thus the effect of homogenising heat radiation cover body 110 interior air.
In order further to improve radiating effect, consult Fig. 3, be the explosive view of LED lighting 100 in the utility model one preferred embodiment.In this pedestal 120, be provided with a radiator 123, it can be wrapped in the inner surface of pedestal 120, and contacts with light source 140 or power supply 150, by conduction, heat absorption is also discharged.In this embodiment, cavity 122 is formed in radiator 123, and the heat that convection effects of ventilating path also can comprise radiator 123 discharges.With respect to cavity 122, be formed on the space between the inner surface of radiator 123 and cover body 110, the radiating effect of above preferred embodiment is better.In addition, in this embodiment, in power supply 150 is arranged on cover body 110, light source 140 is arranged on the lower time of situation in pedestal 120, light source 140 can be set directly on radiator 123, and the sheet metal by light source 140 directly conducts to heat radiator 123, and then heat radiation conducts in cavity 122 again, by ventilating path, heat is discharged again, improved conduction of velocity and the dissipation speed of heat.
More preferably, radiator 123 is comprised of the first radiating part and the second radiating part, and both are oppositely arranged on the inner side of pedestal 120, when the first radiating part and the second radiating part are worked in coordination splicing, has just formed radiator 123.The part of the upper end of the first radiating part and the second radiating part extends to the inside of cover body 110, and with the inner surface laminating of cover body 110, radiator 123 with light fixture in the heat conducting contact area of miscellaneous part larger, its better heat-radiation effect.
In another preferred embodiment, because radiator 123 can partly stop the formation of ventilating path, generation for fear of this problem, on radiator 123, offer the first perforate and the second perforate, the first perforate is communicated with the first through hole 121 and cavity 122, the air entering from the first through hole 121 will be communicated with cavity 122 and the second through hole 131 across and into cavity 122, the second perforates by this first perforate, the air in cavity 122 is flow in the second through hole 131 through the second perforate.
Because radiator 123 is close to the inwall of cover body 110, it can carry out moulding by integrated die-casting, and molding structure can be identical with the structure of cover body 110 inwalls, thereby reaches the effect of laminating completely.Meanwhile, in order to improve the radiating effect of radiator 123, outside radiator 123 or radiator 123 itself as coated or make in moulded alclad etc. by the higher material of thermal conductivity factor, improve best the conducting effect of radiator 123.
In above-mentioned arbitrary embodiment, for cavity 122, cavity 122 is set to become gradually large at pedestal 120 to the cross section in cover body 110 directions alternatively, be that cavity 122 is less compared to the cross section of the opening near support 130 near the opening of pedestal 120 bottoms, in this embodiment, compressed the space of the interior air stream of ventilating path to cavity 122 tops, according to stack effect, hot-air flows out cavity 122 and flow to the flow velocity increase in cover body 110, the filling speed of below cold air is also driven increase, and the convection effects of whole LED lighting 100 is best.
In another preferred embodiment, pedestal 120 outer surfaces are shaped to heat radiating fin structure (not shown), best, pedestal outer surface is the fin of fin-shaped, when lighting 100 normal work, this light fixture also can be wrapped up by heat outward, the air of its outer surface also can flow from top to bottom, when extraneous air is flowed through this lighting 100, the outer surface of pedestal 120 is carried out to heat loss through convection, and fin is because contact area is large, good heat dissipation effect, alleviate the thermolysis of pedestal 120 interior ventilating paths, further improved the radiating effect of LED lighting 100.
Consulting Fig. 4, is LED lighting 100 Air Flow schematic diagrames in the utility model one preferred embodiment.In conjunction with Fig. 4, describe the air direct in ventilating path in detail.In this embodiment, LED lighting 100 is candle bubble lamp, and because candle bubble lamp length is longer, the effect of the stack effect that it is inner is also better.When this candle bubble lamp work, light source 140 or power supply 150 produce heat, by its ambient air heating, after air themperature raises, just upwards flow, by louvre 111, discharge, now, air capacity in cover body 110 reduces, also corresponding reduction of pressure in it, by the second through hole 131, air in cavity 122 is filled in cover body 110, and because the minimizing of the air capacity in cavity 122, pressure in cavity 122 also equally reduces with the air in cover body 110, the first through hole 121 that extraneous air just arranges by pedestal 120 and lamp holder junction flows into, be supplemented in cavity 122, thereby form the ventilating path of automatic filling.
Adopt after technique scheme, solved the heat dissipation problem that adopts the lighting of LED light source, heat light source being produced by the cavity in light fixture and the through hole offered rises along ventilating path, simultaneously cold air is because light fixture inner air and outer air pressure differential is supplemented and entered, form thus the air flow channel of an automatic heat radiation, air circulation, greatly reduce LED light fixture overall thermal resistance, improved the life-span of LED light fixture.
