Description
Technical field
The utility model is related to a kind of light emitting diode, especially a kind of white luminous two pole based on dislocation mounting technology
Pipe.
Background technology
The features such as light emitting diode has luminous efficiency height, energy-saving and environmental protection, long lifespan, is referred to as " green illumination light source ".
More and more higher is required to the light efficiency of LED illumination light source with the issue and room lighting field of Energy Star specification 4.0 editions, in addition
The cost requirement of general illumination field LED/light source popularization, light efficiency, sexual valence to LED semiconductor illuminating light source light emitting diodes
Than requiring more and more higher.
To meet above-mentioned requirements, generally shone at present using single 1W high powers white light-emitting diode as LED semiconductors
The illuminating source in Mingguang City source, wherein single 1W high powers white light-emitting diode is using 2 symmetrical concurrent assemblies of blue-light LED chip
The center on support.Because blue-light LED chip is power LED chips in 0.5W, and concentration is assemblied in carriage center position, leads
Heat ratio is relatively concentrated during photoluminescence diode operation, reduces the service life of chip, accelerates the decay of fluorescent material；Meanwhile, two
The symmetrical concurrent assembly of blue-light LED chip, the spectral absorption that a LEDs chip can send another LEDs chip forward surface is fallen,
Reduce the luminous efficiency of light emitting diode.
The content of the invention
The purpose of this utility model is to solve problems of the prior art there is provided a kind of specular removal, good heat dissipation, photochromic
The dislocation formula white light-emitting diode of uniformity and high reliability.
To achieve the above object, the utility model is adopted the following technical scheme that：A kind of dislocation formula white light-emitting diode, bag
Two blue-light LED chips include support, being assemblied on support, the gold thread that circuit connection is carried out to chip and support, to chip and
The fluorescent glue that gold thread is encapsulated, the LED chip dislocation is parallel to be assemblied in carriage center and is connected from beginning to end with most short gold thread.
It is preferred that, the fluorescent glue is the mixture of fluorescent material and silica gel.Fluorescent material is precipitated using centrifugation technology
In chip surrounding, dislocation formula light emitting diode light Color uniformity is improved.
The utility model compared with prior art, has the following advantages that：
1st, the parallel assembling of two chips dislocations, increases chip chamber away from reducing hot concentration degree, can reduce to fluorescent material
Heat fade, improve lifetime of LED；
2nd, gold thread usage amount is reduced, the cost of LED illumination light source is reduced；
3rd, the parallel assembling of two chips dislocations, two chips forward surfaces are reduced, and during LED operation, can reduce one
The absorption for the spectrum that LED chip is sent to another LEDs chip forward surface, lifts the luminous efficiency of light emitting diode.
