Description
Technical field
The utility model relates to a kind of LED technology field, especially relates to a kind of good heat dissipation, structure is simple, high-performance 360 degree of light emitting LED lamp that cost is low.
Background technology
The osram lamp of artificial light sources from is to state-of-the art electricity-saving lamp, and their illumination mode is to all the winds luminous all the time, is all the illuminating product of 360 degree of luminescences.The luminous characteristics of traditional LED lamp tool has direction one to property, only to project a light beam to a fixing direction.Clearly traditional LED is applied to room lighting towards the photocurrent versus light intensity that a specific direction sends out light beam and can be very restricted, and can not come into huge numbers of families like a cork.
Traditional LED lamp structure generally comprises lampshade, LED light source, lamp plate, lamp body shell, driving, plastic fastening, lamp socket interface, and most of LED lamp also has reflector in addition.This traditional LED lamp lamps structure is complicated, there is a lot of shortcoming: packaging technology is complicated, and material, cost of labor are high; Heat dissipation path is wide, and radiating effect is poor; Luminous efficiency is low, colour temperature 3000K, and light efficiency is 80-90lm/w only.
LEDbulb lamp common on market, lighting angle is little, can not realize omnibearing stereo luminescence, and in most of applied environment, illuminating effect aspect can not substitute incandescent lamp and the electricity-saving lamp of 360 degree of luminescences.Also part producer is had to be proposed the 360 degree of emitting led light fixtures of oneself at present.
As the first, the 360 degree of emitting led light fixtures realized by 3535 lamp pearls, its structure, for being provided with some radiators on ball bubble side, arranging LED illuminator on a heat sink, in limited spatial dimension, carries out wide-angle.But this light fixture also has defect, because radiator is in side, certainly lead to dark space, therefore this mode is not wide-angle truly, does not meet full light distribution type bulb lamp required in CQC certification or Energy Star Valuation Standard.Other 3535 light source costs are high, and suppose 3535 light sources adopting domestic brand, according to 2.5 yuan every calculating, 6 LEDs need 15 yuan! And domestic 3535 light sources are when ensureing colour developing more than 80, naked luminous efficiency of source that is to say 115LM/W, whole light effect=115LM/W*0.8*0.9=82.8LM/W(power-efficient 80%, lampshade light transmittance 90%), namely high cost does not bring high-performance.
The second, Trident Type 360 degree of emitting led light fixtures, its structure comprises three forked cooling stands, three forked cooling stand three terminations are packaged with LED chip respectively, this light fixture is in order to realize larger lighting angle, sacrifice rational passage of heat, light fixture lux maintenance and life-span have received and have a strong impact on.This fitting structure is complicated, and assembling is inconvenient, and material cost of labor is high.And this LED is because only arranging LED light source in side, do not arrange LED light source in light fixture front, the uniformity of luminance of light fixture can not be guaranteed, and agree to that lamp luminescence efficiency is low, colour temperature 3000K, optics is 80-90lm/w only.
The third, class filament 360 degree of emitting led light fixtures, its structure is be arranged on thinner substrate by LED blue chip, then puts the Tinkling-of-gems glass pipe containing fluorescent material or silicone tube, produces and is similar to the silky illumination effect of incandescent lamp tungsten.But this design does not have enough heat sink due to LED chip, and heat radiation causes there is fatal defects not: whole lamp power is difficult to do large, generally more than 4W, can not accomplish more than 500LM; During steady operation, LED chip is too hot, and cold conditions light efficiency difference is not too many for hot light efficiency, and 120LM/W does not reach; Lamp life is not high; The space leaving driving for is too small, is difficult to pass through Safety Approval.
If application number is 201120148195.6, name is called the Chinese invention application of the high efficiency LED of a kind of LED chip 4 π bright dipping, it adopts on transparency carrier and installs LED chip, and coating or encapsulation one deck are mixed with the transparent dielectric layer of fluorescent material, reach the effect of 360 degree of luminescences.Apply this technology to can be made into illuminant colour and be evenly distributed, light emission color temperature, CRI easily control and the good LED of uniformity.Adopt the LED lamp that this kind of LED light source makes, there is following shortcoming equally: the transparency carrier area of 1.LED illuminating source is less, for the area of dissipation of 1mm-2mm*38mm, LED illuminating source is little, cause the radiating effect of light fixture poor, whole lamp power is maximum can only accomplish 4W limited by heat radiation.The volume production difficulty of 2.LED illuminating source is large, and be mainly reflected in, the glass thin of employing, through techniques such as oversampling circuit setting, die bond, bonding wire, fluorescent material coatings, each operation all easily causes substrate crushing; And the two sides of glass substrate all needs to carry out fluorescent material coating, complex process, fluorescent material consumption is high.3. adopt conventional white light technology, namely utilize the dielectric layer method that YAG aluminate yellow fluorescent powder is set on blue chip to make white light, by the restriction of day sub-patent.
Summary of the invention
The utility model mainly to solve in prior art the problems that 360 degree of LED lamp structure are complicated, radiating effect is poor, luminous efficiency is low, manufacturing cost is high, provides a kind of good heat dissipation, structure is simple, high-performance 360 degree of light emitting LED lamp that cost is low.
