Abstract
The utility model discloses an electric light source, in particular to a light-emitting diode with wide spectrum and multi-chip, wherein at least two chips arranged on the same light-emitting diode, the largest wave length difference between different chips is larger than 5 nm, and fluorescent powder with different wave lengths are covered on the different chips, and the wave length of light which is generated by different chips which are covered by different wave length fluorescent power is smaller than 5 nm. The utility model has the advantages that the chips with different wave lengths are applied in the same light-emitting diode, and the spectrum can be widened, which can be used in places with higher requirements of color.
Description
Technical field
The utility model relates to a kind of electric light source, specifically is meant the light emitting diode of a kind of wide range, multicore.
Technical background
Existing multicore grain white light-emitting diode packaged type is that the blue light core grain with same shelves wavelength (wavelength difference is less than 5nm) covers the identical fluorescent material of one deck wavelength on the core grain, the white light-emitting diode colour rendering index that this mode is made lower (Ra＜82) can not be used in the place that color is had relatively high expectations.And the crest of prepared light emitting diode is wide inadequately, and use occasion is restricted., then adopt and be packaged into different products respectively greater than 5nm for the wavelength of different core grains.This method is unfavorable for the use of core grain, and the go-no-go workload of increase core grain etc.
The utility model content
The utility model has proposed a kind of new structure at deficiency of the prior art, can effectively realize the effect of wide range.
The utility model is achieved by following technical proposals:
A kind of wide range multicore grain white light-emitting diode is placed two core grains at least on same light emitting diode, the wavelength maximum difference of different core intergranulars is greater than 5nm, and covers the fluorescent material of different wave length on different core grains.
Above-mentioned a kind of wide range multicore grain white light-emitting diode, the fluorescent material of covering different wave length on the described different core grains, the light wavelength that the different core grains of covering different wave length fluorescent material send is less than 5nm.This also is the requirement to the different fluorescent material that cover on the different core grains, only in this way could realize that last sent light wavelength is identical, to people's vision generation homogeneity.As preferably, on different core grains, cover the fluorescent material of different wave length, the light wavelength that the different core grains of covering different wave length fluorescent material send is identical.The spectrum of the light that light emitting diode sends is broadened, and light intensity is strengthened simultaneously.
As preferably, above-mentioned a kind of wide range multicore grain white light-emitting diode, the wavelength maximum difference of different core intergranulars is greater than 8nm.According to the difference of specification requirement, the wavelength maximum difference of above-mentioned different core intergranulars is greater than 10nm.Can make the spectrum of light emitting diode wideer.
Beneficial effect: can make the core grain of different wave length be applied to same light emitting diode, and spectrum broadens, can be used on the place that color is had relatively high expectations.
