Embodiment
For enabling object of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.Set forth a lot of detail in the following description so that fully understand the present invention.But the present invention can be much different from alternate manner described here to implement, those skilled in the art can when without prejudice to doing similar improvement when intension of the present invention, therefore the present invention is by the restriction of following public concrete enforcement.
See Fig. 1.The assembly type quantum dot light emitting device that the present invention proposes comprises substrate 100, chip 200, light conversion sheet 300.
Chip 200 is emitting LED chip, and encapsulation on the substrate 100.Substrate 100 digs fluted, groove holds chip 200 just, chip 200 encapsulates layer of transparent lid, and transparent cover body can be the material such as glass, silica gel, in the groove that chip 200 is encapsulated on the substrate 100.
See Fig. 2.Light conversion sheet 300 is layer structure, and entirety is lengthy motion picture shape, and material of main part is silica gel, is wherein mixed with quanta point material in silica gel, and light inspires the light of designated color after getting to quanta point material.Light conversion sheet 300 monolithic or multi-disc pile up on chip 200 stackedly, and the light of chip 200 changes photochromic, colour temperature etc. through light conversion sheet 300.
Assembly type quantum dot light emitting devices use luminescence generated by light principle of the present invention, the light of chip 200 is penetrated by the light conversion sheet 300 containing quanta point material, change the color of light, change different quanta point material light conversion sheet 300, utilize equally same luminescence chip 200 and without the need to changing whole lamp, saving resource.One deck light conversion sheet 300 can be installed separately, realize different monochrome and send, also can combine multi-disc light conversion sheet 300, send white light.
Embodiment one
Base plate for packaging 100 encapsulates blue-light LED chip 200 in advance, and the light conversion sheet 300 of a slice doping green quantum dot is installed on blue-light LED chip 200, the blue light that blue-light LED chip 200 sends, by after this light conversion sheet 300, sends green glow, with original blue-light excited, finally send gold-tinted.
Embodiment two
Base plate for packaging 100 encapsulates blue-light LED chip 200 in advance, and two panels light conversion sheet 300 is installed on blue-light LED chip 200, two panels light conversion sheet 300 is respectively the adulterate light conversion sheet of green quantum dot and a slice of a slice and adulterates the light conversion sheet of red quantum point, wherein green quantum dot light conversion sheet is arranged on blue-light LED chip 200, and red quantum point light conversion sheet is superimposed upon in green quantum dot light conversion sheet.The blue light that blue-light LED chip 200 sends is first by green quantum dot light conversion sheet, inspire green glow and blue light, green glow and blue light are through red quantum point light conversion sheet, blue light illumination inspires ruddiness on red quantum point, and part green glow and blue light penetrate through the gap red quantum point, last red, green, blue three kinds of colors finally form white light.
In one preferably synthesize white light embodiment, blue-light LED chip is adopted to be luminescence chip 200, red quantum point, green quantum dot light conversion sheet are stacked on blue-ray LED from top to down, and various quantum dot is distributed in the specific region of corresponding light conversion sheet 300, the proportional relation of area size.Be 1 unit with the light-emitting area of blue-ray LED, then light-emitting area ratio is: blue 1: green 0.5 ~ 0.6: red 0.07 ~ 0.1, can send the white light with higher colour developing coefficient with the configuration of this area.
