Description
Technical field
The present invention relates to a kind of silicone resin composite material, the manufacture method of the silicone resin composite material, contain the silicones
The illuminating device of composite and the silicone resin composite material belong to luminous, lighting field as the application of illuminating device.
Background technology
With the progressively enhancing that global energy crisis and people's energy-conserving and environment-protective are realized, the green energy resource of a large amount of energy-conserving and environment-protective
Our life is come into.Low, heat production is few because consuming energy for light emitting diode (LED), long lifespan the advantages of just progressively replacing it is traditional
Illuminating material, the lighting source as a new generation.
But, with brightness and the continuous improvement of power, fluorescent material and encapsulating material turn into restriction LED and enter illumination neck
One of the key technology in domain.Encapsulating material therein mainly has following effect：
Sealing and protection LED chip normal work, it is to avoid LED chip is influenceed by humidity in surrounding environment and temperature；
Fixed and support wire, prevents that electronic building brick from being produced damaged by mechanical oscillation, impact and causes component parameter
Change；
Heat row of the gap of refractive index to increase light output and effectively produce inside between reduction LED chip and air
Go out.
Therefore, for encapsulating material, it will have excellent sealing, translucency, caking property, refractive index, dielectricity
Energy and mechanical performance.Epoxy resin and organosilicon are the most frequently used LED encapsulation materials.At present, organosilicon encapsulating material is because of it
With uvioresistant photosensitiveness and heat endurance needed for high-brightness LED, it is applied and exploitation is increasingly becoming mainstream technology.
Traditional white light LEDs use and Yellow light-emitting low temperature or the YAG fluoresceins of orange light are covered with blue-ray LED.When gold-tinted and
It just can produce a kind of new photochromic after blue light, its color is closely white in naked eyes.At present, light-emitting phosphor material
Material has been widely applied in LED illumination and Display Technique, but the light decay of fluorescent material is big, granulation uniformity is poor, use
Short life, is not still best LED luminescent material.Compared with natural light, red spectrum is lacked in this secondary colour, and is made
Obtain illuminating LED lamplight and seem ice-cold and dazzling, part fluorescent lamp also has this disadvantage.The high factor of cost is cast aside, from certain
Plant and said in meaning, light is not soft enough to also counteracts that LED enters into family, extensive commercial process.On the other hand, make at present
The particle diameter of fluorescent material is in more than ten micron, the problem of there is the skewness in packaging plastic；Its light scattering effect can add
The aging of fast potting resin material and the service life for shortening LED.Meanwhile, the limitation of encapsulating structure also frequently results in LED spaces
The problem of colourity is uneven.
Quantum dot is higher than the luminous efficiency of fluorescent material, service life is longer, color purity more preferable, as new at present
The study hotspot of LED luminescent material.Quanta point material is to control material Emission by changing the species and size of quantum dot
The scope of spectrum.Quantum dot LED incorporates quantum dot optical design and cool white light LED, using the photochromic controlling technology of quantum dot, leads to
Crossing light stimulation allows quantum dot to exhale varicolored combination, to produce coloury, very bright warm white.Example
Such as, CdSe is important a member of Group II-VI semiconductor material, and the energy gap of its body phase is 1.72 eV, therefore CdSe quantum dot
With the change of particle diameter, its wavelength for launching light can be covered from indigo plant to red almost whole visible region.General red light quantum point
Colour temperature be 2700 Kelvins, as traditional incandescent lamp, its develop the color coefficient be 90, than the colour developing coefficient of conventional incandescent
（95）It is lower slightly, and the colour developing coefficient far above existing LED（75）.In addition, the low energy consumption characteristic of quantum dot is to eliminate high energy comprehensively
Deplete a considerable advantage in source.The blue light that LED/light source is sent can be fully converted to white light by quantum dot, rather than as YAG
Fluorescein can only absorb a part like that, it means that under same bulb brightness, and the blue light needed for quantum dot LED is more
Few, so that the electric power needed in electric light conversion is less, its observable index is 65 lm/W, than the observable index of conventional incandescent（15
lm/W）It is all high with fluorescent lamp efficiency, the energy can be saved more than 80%.
To sum up, quantum dot LED have two it is prominent the characteristics of：（1）Realize the controllable of light color so that icy
LED light line become softer；（2）Importantly, due to that LED primary colours 100% can be converted into white light, quantum dot
LED becomes more efficient and energy-conservation.So that quantum dot LED illumination lamp has LED illumination lamp light efficiency and incandescent lamp simultaneously
Warm colour.
But quantum dot all also has many problems to need to break through in terms of color, life-span, cost and large scale quantities metaplasia production
And improvement.At the same time, fluorescent material is the problem of also space chromacity in urgent need to be improved is uneven.
