Description
Technical field
The invention belongs to LED lamp technical field, particularly relate 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 there is the advantages such as power consumption is low, the life-span is long, therefore light emitting diode is mostly for electronic product indication purposes.But the power of the LED lamp having in using is larger, the life-span of LED light source and the operating temperature of node have closer contacting, at present LED lamp only has 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 Celsius of its reliabilities of the every increase of temperature will reduce half.In great power LED, heat radiation is a large problem especially.If dispelled the heat, bad meeting directly causes LED quick aging, and stability reduces, and the bad meeting of simultaneously dispelling the heat produces serious light decay affects the life-span of lamp.
Example Taiwan I229948 new patent case 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 a 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, due to this light-emitting diode chip for backlight unit and metal connecting line layer, and also two-layer across this ceramic substrate and this heat-conducting glue etc. between this metal body, therefore, heat on this light-emitting diode chip for backlight unit and metal connecting line layer, cannot be transmitted to soon on this metal body and dispel the heat.
The common practices that LED lamp is made is simultaneously: circuit substrate is directly connected to the heat sink material that heat conduction is good, and heat sink material connects radiator again.Object is that heat is conducted by the heat sink radiator that passes to by heat, and then radiator is transferred to external environment condition by heat by cross-ventilation.The use of heat sink and radiator, makes LED lamp increase the weight of weight, has increased cost, has reduced light-emitting area.
In above-mentioned Patent Case, about the way of heat radiation part, still have again in addition improved space, to meet high-capacity LED product to the qualitative high request that dispels the heat.
Summary of the invention
Bad in order to solve in prior art LED lamp radiating effect, easily damage, service life is shorter, and weight is heavier, the little problem of light-emitting area simultaneously, a kind of novel general lighting LED lamp is provided, has compared with existing general lighting LED, the present invention has removed heat sink and radiator, make heat-sinking capability and the light extraction efficiency of LED lamp illuminating source significantly improve, alleviate weight and cost simultaneously, be more applicable to automated production, so that consumption public use to be provided.
In order to address the above problem, the technical solution used in the present invention is:
A kind of LED lamp of fluorescent lamp shade, comprise lamp holder and power supply, in lamp holder, be 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, described fluorescent lamp shade is set to taper, the more past bottom opening of fluorescent lamp shade is larger, described cartridge type wick assembly is arranged in fluorescent lamp shade, on cartridge type wick assembly, be prefabricated with breach, described curved surface LED light source inserts breach and is fixed on cartridge type wick assembly, and be connected conducting with the power supply in lamp holder, at fluorescent lamp shade top, be evenly provided with pierced pattern or netted eyelet.
The LED lamp of aforesaid a kind of fluorescent lamp shade, it is characterized in that: described curved surface LED light source is rolled into by the bending of sheet type LED light source, described sheet type LED light source comprises flexible circuit board, at the tow sides of flexible circuit board, have chips incorporate district and several electrode district, multiple LED chips or packaged LED lamp pearl are directly mounted on chips incorporate district simultaneously.
The LED lamp of aforesaid a kind of fluorescent lamp shade, is characterized in that: described fluorescent lamp shade adopts polyester material, and the one in glass or crystal material is 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 mixing in described fluorescent lamp shade is containing nitride or the oxide particle of rare earth.
The LED lamp of aforesaid a kind of fluorescent lamp shade, is characterized in that: described lamp holder bottom adopts and is threaded with fluorescent lamp shade top,
The LED lamp of aforesaid a kind of fluorescent lamp shade, is characterized in that: fluorescent lamp shade top is evenly provided with some ellipses or bar shaped perforate.
The invention has the beneficial effects as follows:
1, the present invention is without heat sink and radiator, and weight reduction, reduces costs.Because flexible circuit board is very thin, the heat of LED lamp is delivered to flexible circuit board surface at once, then directly by dispelling the heat with cross-ventilation.LED thermal source and the cross-ventilated passage of heat of this invention are the shortest, and entire thermal resistance is also minimum, thereby good heat dissipation effect, reduces heat sink and component weight and cost radiator simultaneously.
2, the present invention is under the structure that adds lampshade, and for heated air is discharged in time, 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 by circuit substrate, has strengthened the luminous efficiency of LED chip.
4, justifying plane formula or curved face type encapsulating structure, expanded light source luminescent pattern, strengthens the heat-sinking capability of product simultaneously, avoided the shortcoming of traditional LED lamp decoration heat-sinking capability.
5, the present invention, according to the rising angle design fluorescent lamp shade tapering of computer simulation curved surface LED light source, improves the utilization rate of light source greatly.
6, the design of the hollow type on lampshade top has taken into account the operating characteristic in client's use, and hollow type design optimization the heat dispersion of light source self, simultaneously curved face type LED light source can directly insert from hollow out position, installs and replace easy, has improved the efficiency of assembly and disassembly.
