Abstract
The invention discloses a long-service-life LED energy-saving lamp, and overcomes the defects that existing LED energy-saving lamps are poor in radiating effect, short in service life, large in material consumption, high in manufacturing cost and the like. Radiating passages penetrated from one sides to the other sides are arranged among radiating fins, an integral radiating mechanism is provided with the radiating passages penetrated from one side to the other side, a driving power supply assembly cavity is arranged on the lower portion of a lamp holder assembly, and cavity radiating holes are reserved on the wall of the driving power supply assembly cavity. The long-service-life LED energy-saving lamp as a lighting lamp is good in radiating, long in service life, simple in structure, small in material consumption, convenient to manufacture, low in processing cost and obviously improved in cost performance of LED energy-saving lamps, and compared with the existing LED energy-saving lamps, the long-service-life LED energy-saving lamp has the advantages that inside and outside temperature accumulation is lowered by more than 50%, consumed materials are saved by 30%, comprehensive cost is reduced by 40%, and the service life of the LED energy-saving lamp can be prolonged by more than one third.
Description
Technical field
The present invention relates to a kind of illuminating lamp, be specially a kind of LED long-life energy-saving lamp.
Background technology
Will produce a large amount of heats during the work of LED electricity-saving lamp, its operation principle makes heat dissipation problem become very outstanding, if heat radiation is not smooth, is easy to burn out members such as its driving power (power transformation) assembly, led chip.
The deficiency of existing LED electricity-saving lamp is, it has the lumen that placement driving power (power transformation) assembly is installed with the cooling mechanism that lamp holder is connected with the LED central layer respectively, the perisporium sealing of this lumen, the perisporium of this airtight lumen has some fin that are radial arrangement, entire heat dissipation mechanism does not have penetrating heat dissipation channel (hot-air convection passage) from one side to another side, air can not transverse convection, radiating effect is poor, the temperature of its lumen reaches more than 80 degrees centigrade, be easy to burn out its driving power (power transformation) assembly, members such as led chip, make the lost of life, improved the use cost of LED electricity-saving lamp greatly, because the heat dissipation technology problem makes LED lamp ubiquity be nothing like theoretical value actual life, cost performance is lower than conventional lamp; Moreover, and this airtight lumen around some heat abstractors that are the fin of radial arrangement are set, the processing technology complexity, consumptive material is many, the manufacturing cost height.
Summary of the invention
Purpose of the present invention is exactly at above-mentioned deficiency, provides a kind of good heat dissipation, the life-span is long, simple in structure, consumptive material is few, manufacturing is easy, processing cost is low, can significantly improve the LED long-life energy-saving lamp of LED electricity-saving lamp cost performance.
For achieving the above object, technical scheme of the present invention is: this LED long-life energy-saving lamp, comprise lamp adapter assembly, LED central layer and the cooling mechanism that is connected with the LED central layer with lamp adapter assembly respectively, described cooling mechanism has and has between fin, described each fin from the penetrating heat dissipation channel to another side in one side, and entire heat dissipation mechanism has from the penetrating heat dissipation channel to another side of one side.So just can make the long-pending heat energy of middle part or lumen enough pass through penetrating heat dissipation channel transverse convection outside cooling mechanism, good heat dissipation effect.
Described fin has thermovent.To increase heat radiation to fluidity.
Described lamp adapter assembly has driving power assembly chamber, is used for installing or placing the driving power assembly, and the chamber wall in this driving power assembly chamber has the heat dissipation channel (chamber wall blow-by) of thermal air current outside the chamber that makes in the chamber.
Described driving power assembly chamber is arranged at the bottom of lamp adapter assembly, and the lower end of described driving power assembly cavity is connected with described cooling mechanism.
The chamber wall in described driving power assembly chamber has the cavity radiating mouth.
The present invention has fin with lamp adapter assembly with the cooling mechanism that the LED central layer is connected respectively, have between each fin from the penetrating heat dissipation channel to another side in one side, entire heat dissipation mechanism has from the penetrating heat dissipation channel to another side of one side, described fin has thermovent, the a large amount of heats that produce when making the work of LED electricity-saving lamp can pass through fin conductive, to flowing to the heat dissipation channel between the fin, because this heat dissipation channel is penetrating to another side from the one side of heat abstractor, fin itself has thermovent again, the hot-air that is heated in the heat dissipation channel is easy to convection current, so good heat dissipation effect, according to measuring and calculating, the temperature at the present invention middle part is lower than 40 degrees centigrade; Secondly, driving power assembly of the present invention installs or is arranged on that (lumen of cooling mechanism is installed or be arranged on to existing driving power assembly in the driving power assembly chamber of lamp adapter assembly bottom, and the sealing of chamber wall), and the chamber wall in driving power assembly chamber has the cavity radiating mouth, radiating effect is better, the thermal shock that the driving power assembly is subjected to is littler, more is conducive to prolong its life-span.
In addition, described each fin can be interconnected to form 2 whole end faces in its end, on this integral body end face installing mechanism can be set, LED central layer, lamp adapter assembly etc. can be installed, this makes its structure and processing technology very simple, low cost of manufacture, and consumptive material is few.
The present invention is as illuminating lamp, and is not only energy-conservation, and because good heat dissipation and the life-span prolongs, simple in structure, consumptive material is few, manufacturing is easy, processing cost is low, can significantly improve LED electricity-saving lamp cost performance.The inside and outside accumulated temperature of its existing LED electricity-saving lamp is low, and consumptive material economizes 30% more than 50%, and integrated cost is low by 40%, can make the long service life of LED electricity-saving lamp more than 1/3rd.
