At present, white LED lamp as a kind of novel illumination light source of energy-conserving and environment-protective gradually by consumer's extensive use.LED
Lamp produces white light using blue light or laser radiation-induced fluorescence, and blue photons energy is high, can excite fluorescence.Relative to normal light
Source has multiple advantages such as energy-saving and environmental protection, impact resistance, antidetonation, but current white LED lamp is in the process irradiated and induced
In, blue light and laser itself can all have a big chunk energy conversion into high heat, so as to cause LED meeting luminous while
Amount of heat is produced, the decay of fluorescent material is then directly resulted in, shortens a series of defects such as light source life.
For work when caused high heat, at present the radiating mode of LED mainly have following two：(1) light fixture dissipates
Heat, lamp piece apply the radiating surface in light source to add for example air-cooled radiating module, water cooling, heating column fin etc. to radiate by the later stage.
This radiating mode carries out heat transfer only by lamp piece aluminium base, and tin at lamp piece supply lines solder joint can be caused when temperature is too high
Thawing comes off, and fluorescent material produces the vestige of calcination so as to influenceing normal luminous.(2) design the exciting using separate type of lamp piece
Mode, composite phosphor is accurately attached on substrate, separated with blue led light source, makes fluorescent material away from thermal source.Second
Kind of mode is separated with light source due to fluorescent material so that fluorescent material temperature is relatively low, it is possible to reduce the decay of fluorescent material, but this side
Method is only somewhat to increase the distance between fluorescence and thermal source without heat is distributed by conduction, the heat in real work
Amount can equally accumulate and cause to radiate bad.
The content of the invention
Caused high heat during to overcome existing LED timely and effective can not distribute work, so as to cause fluorescence mealiness
The problems such as energy decay, light source life shorten, the present invention discloses a kind of high heat conduction long-life phosphors piece.It is intended to utilize transparent graphene
High thermal conductivity realize quick heat radiating, so as to improve the service life of flourescent sheet.
The present invention solves the technical scheme that above-mentioned technical problem uses：A kind of high heat conduction long-life phosphors piece, its feature
It is：It is made up of quartz glass, transparent graphene and fluorescent material, wherein, quartz glass adheres to transparent graphene as substrate
