Abstract
Disclosed is an interlayer diffusant white-light LED of a direct-embedded type, and the LED comprises an LED support bowl, an LED chip, phosphor glue, diffusant glue, and epoxy resin packaging glue. The LED chip is installed at the bottom of the LED support bowl. The phosphor glue is directly coated on the periphery of the LED chip. The diffusant glue is coated on the phosphor glue. The epoxy resin packaging glue covers the periphery of the LED support bowl. According to the utility model, an LED light spot is greatly improved without shortening the service life of a direct-embedded white-light LED, and the color uniformity of the output light is remarkably improved.
Description
Technical field
The utility model relates to the LED field of illuminating lamps, is specially a kind of interlayer diffusant direct plugging-in white light LEDs.
Background technology
The LED lamp adopts the light fixture product of LED (Light-emitting Diode, light-emitting diode) technology as main light emitting source exactly.LED is a kind of solid-state semiconductor subassembly, it utilizes electric current forward to be passed to coupling place of semiconductor p-n junction, after the electronegative electronics separated in semiconductor again and two kinds, the hole of positively charged carrier mutually combine, and the generation photo emissions, between different types of LED can send from the infrared ray to the blue light, and purple light to the light of the different wave length such as between ultraviolet ray.New development in recent years is to be coated with fluorescent material on blue-light LED chip, and blue-ray LED is changed into to the white light LEDs product.
The lamp pearl volume of LED light fixture is little, lightweight, and with epoxy encapsulation, but bearing high strength mechanical shock and vibrations be difficult for fragmentation, and the brightness decay cycle are long, so be 50,000-100,000 hour its useful life.Owing to service life of LED light fixture can reaching 5～10 years, so not only can significantly reduce the cost that light fixture is replaced, because having minimum electric current, it can drive luminous speciality again, in the situation that same illuminating effect, power consumption also only has 1/2nd of fluorescent tube, so LED also has power saving and energy-conservation advantage simultaneously.During current straight cutting white-light LED encapsulation, add diffusant in phosphor gel and can cause the lost of life, the hot spot effect is bad not add diffusant.For head it off, we research and propose a kind of interlayer diffusant direct plugging-in white light LEDs, while adopting the straight cutting white-light LED encapsulation, add a part of phosphor gel in support bowl cup, high one deck adds brightener glue, finally carries out epoxy encapsulation, when not reducing the straight cutting white light LEDs life-span, obviously improved the LED hot spot, the color homogeneity of output light obviously improves.
The utility model content
The technical problem that the utility model solves is to provide a kind of interlayer diffusant direct plugging-in white light LEDs, to solve the problem proposed in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of interlayer diffusant direct plugging-in white light LEDs, comprise LED support bowl cup, LED chip, phosphor gel, diffusant glue, epoxy encapsulation glue; Described LED chip is arranged on the bottom of LED support bowl cup; Described phosphor gel directly is coated on the periphery of LED chip; Described diffusant glue be coated on phosphor gel above; Described epoxy encapsulation glue is coated on LED support bowl cup surrounding.
Further, described phosphor gel is silica gel mixing yellow fluorescent powder;
Further, described diffusant glue is silica gel mixing diffusant;
Beneficial effect:
The utility model, when not reducing the direct plugging-in white light LEDs life-span, obviously improves the LED hot spot, and the color homogeneity of output light obviously improves.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make of the present utility modelly to realize technological means, creation characteristic, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of interlayer diffusant direct plugging-in white light LEDs, comprise LED support bowl cup 1, LED chip 2, phosphor gel 3, diffusant glue 4, epoxy packages glue 5; Described LED chip 2 is arranged on the bottom of LED support bowl cup 1; Described phosphor gel 3 directly is coated on the periphery of LED chip 2; Described diffusant glue 4 be coated on phosphor gel 3 above; Described epoxy packages glue 5 is coated on LED support bowl cup 1 surrounding.
Further, described phosphor gel 3 is silica gel mixing yellow fluorescent powder;
Further, described diffusant glue 4 is silica gel mixing diffusant;
The utility model, when making, utilizes glue dispenser with high precision first to put the phosphor gel in bottom, puts the diffusant glue in upper strata after oven dry again, carries out peripheral epoxy encapsulation after oven dry again.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
