Lamp generates white light using blue light or laser radiation-induced fluorescence, and blue photons energy is high, can excite fluorescence.Compared with normal light
Source has the advantages that energy-saving and environmental protection, impact resistance, antidetonation etc. are multiple, but current white LED lamp is in the process irradiated and induced
In, blue light and laser itself all can have a big chunk energy to be converted into high heat, the meeting luminous while so as to cause LED light
Amount of heat is generated, the attenuation of fluorescent powder is then directly resulted in, shortens a series of defects such as light source life.
For work when generated high heat, at present the radiating mode of LED light mainly have following two：(1) lamps and lanterns dissipate
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 aluminum substrate, can cause tin at lamp piece supply lines solder joint when the temperature is excessively high
Thawing comes off, and fluorescent material generates the trace of calcination so as to influence normal luminous.(2) design of lamp piece uses the excitation of separate type
Composite phosphor is accurately attached on substrate, is separated with blue led light source, makes fluorescent material away from heat source by mode.Second
Kind of mode is separated due to fluorescent powder with light source so that fluorescent powder temperature is relatively low, it is possible to reduce the attenuation of fluorescent powder, but this side
Method is only slightly to increase the distance between fluorescence and heat source without heat is distributed by conduction, the heat in real work
Amount can equally accumulate and cause to radiate bad.
Utility model content
