Description
Technical field
The present invention relates to a kind of LED illuminating device, specifically be meant 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, in light weight, shock-resistant, environmental protection does not pollute the environment; It is big to be easy to light modulation toning controllability; Power consumption is low, has the more superior advantage of other electric light source luminescent device, more and more enjoys people's attention.
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 practical application, could send out its superiority of brightness.
Led light source generally is divided into ruddiness, blue light, gold-tinted; And the working voltage of the led chip of three kinds of different colours has nothing in common with each other, and the client in use, often needs the different colours use that mixes; Can be assembled into motley color lamp etc.; If the voltage of each LED lamp pearl has nothing in common with each other, the then as easy as rolling off a log damage that causes part lamp pearl finally causes can't using of entire product.So, directly assemble the color lamp that mixes through various led chip, then to causing totally unfavorable consequence the service life of color lamp,, also be a very thing of difficulty if will prepare the different LED light source under the identical working voltage situation.
In addition, use common energy-saving lamp in a large number, can cause mercury pollution, contaminated soil water source, thereby indirect contaminated food products, 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,, then exist voltage distribution uneven and cause the result that spoilage is high, do not grow service life if use together.
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 through following technical proposals:
A kind of yellow light LED light source assembly, 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 are formed, and the silicate yellow powder is a yttrium aluminate, and the silicate orange toner is an 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 light LED light source assembly
3MgSi

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 light LED light source assembly.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.
Coat for wherein is a key technology of the present invention; It also is important means to color change among the present invention; After blue-light LED chip is luminous; Changed the color of light behind the process 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:,, and can together use better because of working voltage is identical with the blue-ray LED light source assembly through the red-light LED light source assembly of the prepared gained of the present invention; Guarantee longer service life, working voltage is 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 utilization again, high light efficiency.
Extra long life: semiconductor chip is luminous, no filament, and no 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 has only 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: DC driven, no stroboscopic ordinary lamps all is an AC driving, 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 big: low pressure, direct current supply, battery, solar powered is in shorts of electricity such as outlying mountain area and open-air illumination, 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, the uniformity, battery or the solar-energy photo-voltaic cell service time that mainly show brightness were than the long 5-8 of traditional gold-tinted hour.
