Description
Technical field
The utility model relates to the LED lighting apparatus, relates in particular to a kind of integrated LED lamp that contains fluorescent lamp shade without radiator.
Background technology
Light emitting diode is a kind of high efficiency cold light light-emitting component that converts electrical energy into luminous energy, and has the advantages such as power consumption is low, the life-span is long, so light emitting diode is used for electronic product indication purposes mostly; The family expensesization of light emitting diode mainly occur in the mode of LED lamp.The LED lamp is take of fine quality, durable, energy-conservation as main feature, and the crevice projection angle adjustable range is large, and high temperature resistance, moistureproof and waterproof, the advantage such as anticreep make its main flow that replaces existing fluorescent lamp and become in the lighting field form gradually trend.
Usually our the LED lamp that uses all is white light LEDs, and LED produces white light and mainly contains two kinds of approach: the first is that ruddiness, green glow and three kinds of led chips of blue light are carried out the combination results white light; The second is to form white light with the photic conversion phosphor of LED deexcitation, and the mode that this approach is comparatively ripe is to use blue-light LED chip collocation yellow fluorescent powder (such as YAG:Ce3+ etc.) to realize white light emission.
For the white light LEDs of photic conversion, the structure of fluorescent coating, characteristic etc. have vital impact to the performance of white light LEDs.At present the technique of such fluorescent coating of preparation is with after transparent colloid (such as epoxy glue, silica gel etc.) mixes, by point gum machine, at the mixture layer of led chip coating fluorescent powder grain and transparent colloid with fluorescent powder grain.The concrete technology method is:
(1) led chip is fixed on the support with rim of a cup;
(2) with gold thread bonding LED chip both positive and negative polarity;
(3) colloid (silica gel, epoxy resin etc.) is mixed formation fluorescent material mixed liquor with fluorescent material;
(4) carrying out selecting glue by point gum machine is coated in the fluorescent material mixed liquor on the led chip.
But there is following shortcoming in above-mentioned technique: 1, the fluorescent material mixed liquor can be subjected to the impact of carrier cup mouth-shaped and produce yellow circle or blue circle phenomenon, affects light quality; 2, the mode of selecting glue be after using the mechanical function such as gravity to flow by the fluorescent material mixed liquor with the led chip parcel, being difficult to guarantee the uniformity of fluorescent coating affects light-emitting uniformity; 3, it is poor to be coated in the repeatability of the fluorescent coating on the led chip, has greatly restricted mass production and yield rate.
The power of the LED lamp that has in the use is larger, the life-span of LED wick and the operating temperature of node have closer contacting, at present the 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 centigrade of its reliabilities of the every increase of temperature will reduce half.In high-powered LED lamp, heat radiation is a large problem especially.Bad meeting directly causes the quick aging of LED wick if dispel the heat, and stability reduces, bad can the generation life-span that serious light decay affects lamp of dispelling the heat simultaneously.
Because the heat-sinking capability of existing LED wick itself is limited, under hot environment, use for a long time its life-span and stable impact for fear of the LED wick, the radiator device that is absolutely necessary, but the volume of radiator is large, quality heavy, thereby can affect shape-designing and the illumination effect of whole LED lamp, greatly increased manufacturing and cost of transportation simultaneously.
