Description
Technical field
The utility model belongs to LED lamp technical field, particularly relates to a kind of LED lamp of fluorescent lamp shade.
Background technology
Because light emitting diode is a kind of high efficiency cold light light-emitting component that converts electrical energy into luminous energy, and have advantages such as power consumption is low, the life-span is long, so light emitting diode is used for electronic product indication purposes mostly.But the power of the LED lamp that has in being to use is bigger; The life-span of led light source and the operating temperature of node have closer getting in touch; At present the LED lamp has only about 50% electric energy to convert luminous energy in the course of the work; Remaining electric energy nearly all changes into heat energy, the temperature of LED lamp is raise, and 10 degrees centigrade of its reliabilities of the every increase of temperature will reduce half.In great power LED, heat radiation is a big problem especially.Bad meeting directly causes the LED quick aging if dispel the heat, and stability reduces, bad can the generation life-span that serious light decay influences lamp of dispelling the heat simultaneously.
The novel patent case of example Taiwan I229948 discloses a kind of crystal-coated light-emitting diodes array of packages and encapsulation unit thereof, mainly discloses a light-emitting diode chip for backlight unit and is arranged on the ceramic substrate, and connect the metal connecting line layer on this ceramic substrate.This porcelain substrate is to utilize heat-conducting glue suddenly in the depression of a metal body.Under this way; Because this light-emitting diode chip for backlight unit and metal connecting line layer; And it is also two-layer between this metal body across this ceramic substrate and this heat-conducting glue etc.; Therefore, the heat on this light-emitting diode chip for backlight unit and the metal connecting line layer can't be transmitted to soon on this metal body and dispel the heat.
The common practices of LED lamp making simultaneously is: circuit substrate is directly connected the good heat sink material of heat conduction, and heat sink material connects radiator again.Purpose is that heat is conducted by the heat sink radiator that passes to through heat, and radiator is transferred to external environment condition with heat through cross-ventilation then.The use of heat sink and radiator makes the LED lamp increase the weight of weight, has increased cost, has reduced light-emitting area.
Relevant heat radiation way partly in the above-mentioned patent case still has in addition improved space, to meet the high-capacity LED product to the qualitative high request that dispels the heat again.
The utility model content
Bad in order to solve in the prior art LED lamp radiating effect, to damage easily, service life is shorter; Weight is heavier, and the little problem of light-emitting area provides a kind of novel general lighting LED lamp simultaneously; Compare with existing general lighting LED, the utility model has been removed heat sink and radiator, makes the heat-sinking capability and the light extraction efficiency of LED lamp illuminating source significantly improve; Alleviated weight and cost simultaneously, be fit to automated production more, consumption is popular to be used to provide.
In order to address the above problem, the technical scheme that the utility model is taked is:
A kind of LED lamp of fluorescent lamp shade comprises lamp holder and power supply, in lamp holder, is provided with power supply; It is characterized in that: also comprise fluorescent lamp shade, curved surface LED light source and cartridge type wick assembly, below lamp holder, be provided with fluorescent lamp shade, said fluorescent lamp shade is set to taper; The more past bottom opening of fluorescent lamp shade is big more; Said cartridge type wick assembly is installed in the fluorescent lamp shade, and is prefabricated jagged on cartridge type wick assembly, and said curved surface LED light source inserts breach and is fixed on the cartridge type wick assembly; And be connected conducting with the power supply in the lamp holder, evenly be provided with pierced pattern or netted eyelet at the fluorescent lamp shade top.
The LED lamp of aforesaid a kind of fluorescent lamp shade; It is characterized in that: said curved surface LED light source is rolled into by the bending of sheet type led light source; Said sheet type led light source comprises flexible circuit board; Tow sides at flexible circuit board have chips incorporate district and several electrode districts simultaneously, and a plurality of led chips or packaged LED lamp pearl directly are mounted on the chips incorporate district.
The LED lamp of aforesaid a kind of fluorescent lamp shade is characterized in that: said fluorescent lamp shade adopts polyester material, a kind of in glass or the crystal material as base material, and mixed fluorescent powder carries out granulation, moulding.
The LED lamp of aforesaid a kind of fluorescent lamp shade is characterized in that: the fluorescent material that mixes in the said fluorescent lamp shade contains the nitride or the oxide particle of rare earth.
The LED lamp of aforesaid a kind of fluorescent lamp shade is characterized in that: said lamp holder bottom is adopted with the fluorescent lamp shade top and is threaded,
The LED lamp of aforesaid a kind of fluorescent lamp shade is characterized in that: the fluorescent lamp shade top evenly is provided with some ellipses or bar shaped perforate.
The beneficial effect of the utility model is:
1, the utility model does not have heat sink and radiator, and weight reduction reduces cost.Because flexible circuit board is very thin, the heat of LED lamp is delivered to the flexible circuit board surface at once, then directly through dispelling the heat with cross-ventilation.The LED thermal source of this utility model and the cross-ventilated passage of heat are the shortest, and entire thermal resistance is also minimum, thereby good heat dissipation effect, reduces heat sink simultaneously and component weight and cost radiator.
2, the utility model is adding under the structure of lampshade, in time discharges in order to make heated air, and lampshade has mesh or hollow out up and down.And the air of circulation improves heat loss through convection.
3, flexible circuit board adopts transparent material, and part light spreads out of through circuit substrate, has strengthened the luminous efficiency of led chip.
4, justifying plane formula or curved face type encapsulating structure have enlarged the light source luminescent pattern, strengthen the heat-sinking capability of product simultaneously, have avoided the shortcoming of traditional LED lamp decoration heat-sinking capability.
5, the utility model improves the utilization rate of light source according to the rising angle design fluorescent lamp shade tapering of computer simulation curved surface LED light source greatly.
6, the design of the hollow out formula on lampshade top has taken into account the operating characteristic in client's use; And hollow out formula design optimization the heat dispersion of light source self; Simultaneously the curved face type led light source can directly insert from the hollow out position, installs and replace easy, has improved the efficient of assembly and disassembly.
