Description
Technical field
The present invention relates to a kind of LED illuminating device, specifically refer to a kind of yellow led light source assembly of after applying, changing into.
Technical background
LED is as an electric light source luminescent device, because its long working life, response is fast, volume is little, lightweight, shock-resistant, environmental protection does not pollute the environment, it is large to be easy to light modulation toning controllability, power consumption is low, have the more superior advantage of other electric light source luminescent device, more and more enjoy people's concern.
As an electric light source luminescent device, LED must dispose suitable drive circuit and carry out the work of normal reliable according to the C-V characteristic of itself in actual applications, could send out its superiority of brightness.
Led light source generally is divided into ruddiness, blue light, gold-tinted, and the use voltage of the led chip of three kinds of different colours is different, and the client in use, often need the different colours use that mixes, can be assembled into motley color lamp etc., if the voltage of each LED lamp pearl is different, the then as easy as rolling off a log damage that causes part lamp pearl finally causes can't using of whole product.So, directly assemble the color lamp that mixes by various led chip, then to causing totally unfavorable consequence the service life of color lamp, if will prepare the different LED light source under the identical use voltage condition, also be a very thing of difficulty.
In addition, use in a large number common energy-saving lamp, can cause mercury pollution, contaminated soil water source, thereby contaminated food products indirectly, environmental hazard can not be despised.
The voltage of tradition ruddiness, gold-tinted is 1.8v-2.3v all, and the voltage of blue light is 3.0v-3.8v; So when making color lamp, have the inconsistent problem of voltage of voltage and the blue light of ruddiness, gold-tinted, if use together, then exist voltage distribution uneven and cause the result that spoilage is high, do not grow service life.
Summary of the invention
The present invention is directed to deficiency of the prior art, proposed a kind of convenience, feasible method, realize the led light source assembly of different colours, identical voltage.
The present invention is achieved by following technical proposals:
A kind of Yellow LED light source component, it comprises substrate, blue-light LED chip, encapsulant, power connection points wherein have one deck coat between blue-light LED chip and encapsulant; Wherein said coat is the mixture that silicate orange toner and silicate yellow powder form, and the silicate yellow powder is yttrium aluminate, and the silicate orange toner is alkaline-earth silicate; The mass ratio of yellow powder and orange powder is 6: 1.The yellow that the led light source assembly is produced is the softest and color is the most beautiful.
As preferably, alkaline-earth silicate is Me in above-mentioned a kind of Yellow LED light source component
3MgSi

2O
8) middle Me is Sr, or Ca
2-xSiO
3: Eu
x, x=0.05 wherein.
As preferably, above-mentioned stating in a kind of Yellow LED light source component adds ZnO and B in silicate yellow powder and silicate orange toner
2O
3Powder, the adding weight of ZnO powder is 5～7% of above-mentioned two kinds of silicate consumptions, B
2O
3The adding weight of powder is 3～4% of above-mentioned two kinds of silicate consumptions.
As preferably, substrate is connected with current-limiting resistance in above-mentioned a kind of Yellow LED light source component.Play further protection, coordinative role.
In the present invention, the led chip that employed blue-light LED chip is produced, buied for conventional institute, encapsulant also are conventional epoxy resin etc.
Be key technology of the present invention for wherein coat, it also is the important means to color change among the present invention, after blue-light LED chip is luminous, through having changed the color of light behind the coat, and the employed voltage of led chip still is original blue-light LED chip, so very easily also other blue-light LED chip is assembled into color lamp etc.
Beneficial effect: by the red-light LED light source component of the prepared gained of the present invention, because using voltage identical with the blue-ray LED light source assembly, and can use better together, guarantee longer service life, use voltage more stable, anti-frequent switch, light decay is little, rich color, tunable optical, change is abundant; Compare common energy-saving lamp, the environmental protection of LED electricity-saving lamp is not mercurous, recyclable recycling, high light efficiency.
Extra long life: semiconductor chip is luminous, without filament, without glass envelope, is not afraid of vibrations, is difficult for fragmentation, and can reach 50,000 hours ordinary incandescent lamps service life only has 1,000 hours service life, and common energy-saving lamp also only has 8,000 hours service life.
Light is healthy, and it is few to contain ultraviolet ray and infrared ray in the light, produces in the few ordinary lamps light of radiation to contain ultraviolet ray and infrared ray; Vision protection: direct drive all is to exchange to drive without the stroboscopic ordinary lamps, just certainly leads to stroboscopic.
Safety coefficient is high: required voltage, electric current are less, and potential safety hazard is little, in hazardous areas such as mining sites.Market potential is large: low pressure, direct current supply, battery, solar powered is in the shorts of electricity such as outlying mountain area and field illuminating, few electric field institute.
The present invention is suitable for use in battery four Color lamp strings and solar energy four Color lamp strings; Whole lamp conspires to create this reduction 20%-30%, is mainly reflected in consumption, the efficient of production, the production and processing cost of electric wire.In addition, produce many that the whole structure of finished product will be good than traditional gold-tinted production, be mainly manifested in the uniformity, battery of brightness or solar-energy photo-voltaic cell service time than the long 5-8 of traditional gold-tinted hour.
