Abstract
The invention discloses a yellow fluorescent adhesive for LEDs. The yellow fluorescent adhesive is formed by mixing the following components in parts: 80-100 parts of silica gel, 20-30 parts of a silica gel adhesive, 50-60 parts of yellow fluorescent powder, 5-8 parts of aluminum oxide, 5-6 parts of aluminum sulfide, 8-10 parts of zinc sulfide, 5-10 parts of magnesium sulfide, 6-7 parts of magnesium sulfate and 8-10 parts of potassium carbonate. The yellow fluorescent adhesive for LEDs can effectively excite the fluorescent powder and mix proper white light, has the advantages of being scientifically and reasonably designed, high in effective exciting reliability, able to shield yellow rings and low in cost, and can effectively reduce photon loss caused by refractive index physical barriers and improve external quantum efficiency.
Description
Technical field
The present invention relates to a kind of LED yellow fluorescent glue, particularly relate to the LED yellow fluorescent glue that a kind of high-power LED light source energy-saving lamp uses.
Background technology
At present, in LED industry, LED connects to fall on the electrode of LED chip by outer lead, so that be connected with other devices.It not only realizes chip connecting in external circuit by being fallen by the Electrode connection on chip with wire on package casing, and is fixed by chip and seal, and does not cause electric property to reduce with protect IC circuit by the erosion of the material such as water, air.In addition, encapsulation can also improve the light extraction efficiency of LED chip, and provides convenience for the application installation of downstream industry and transport.Therefore, the Performance And Reliability of encapsulation technology to LED plays an important role.LED technology; fluorescent material and the LED casting glue in LED thereof; it is a kind of auxiliary material of LED; there is high index of refraction and high permeability; can play the luminous flux that protection LED chip increases LED, viscosity is little, easy deaeration; be applicable to filling and sealing machine compression molding, make LED have good durability and reliability.In LED use procedure, the loss that the photon that radiation recombination produces produces when outwards launching.The fluorescent material of each model all needs to arrange in pairs or groups the blue led wafer of applicable fluorescent material, could effective excitated fluorescent powder and mix comparatively suitable white light.
Summary of the invention
The present invention is the defect in order to overcome prior art, object is to provide a kind of LED yellow fluorescent glue, this LED yellow fluorescent glue can effective excitated fluorescent powder and mix comparatively suitable white light, there is design science reasonable, effectively excite reliability strong, and yellow circle can be covered, low cost and other advantages, effectively can reduce the photon loss that refractive index physical barriers brings, improve external quantum efficiency.
The technical solution adopted for the present invention to solve the technical problems is: a kind of LED yellow fluorescent glue, mixed by the component of following number and form: 80-100 part silica gel, 20-30 part silica adhesive, 50-60 part yellow fluorescent powder, 5-8 part aluminium oxide, 5-6 part aluminium sulfide, 8-10 part zinc sulphide, 5-10 part magnesium sulfide, 6-7 part magnesium sulfate, 8-10 part potash.
Further, be made up of the component of following number: 80 parts of silica gel, 20 parts of silica adhesives, 50 parts of yellow fluorescent powders, 5 parts of aluminium oxide, 5 parts of aluminium sulfides, 8 parts of zinc sulphide, 5 parts of magnesium sulfides, 6 parts of magnesium sulfate, 8 parts of potash.
Or, be made up of the component of following number: 100 parts of silica gel, 30 parts of silica adhesives, 60 parts of yellow fluorescent powders, 8 parts of aluminium oxide, 6 parts of aluminium sulfides, 10 parts of zinc sulphide, 10 parts of magnesium sulfides, 7 parts of magnesium sulfate, 10 parts of potash.
In sum, LED yellow fluorescent glue of the present invention can effective excitated fluorescent powder and mix comparatively suitable white light, there is design science reasonable, effectively excite reliability strong, and yellow circle can be covered, low cost and other advantages, effectively can reduce the photon loss that refractive index physical barriers brings, and improves external quantum efficiency.
