Following detailed description of the invention will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
Refer to Fig. 1, the present invention one better embodiment provides a kind of expansion light part 100 establishing light source for cover.The material of this expansion light part 100 contains epoxy resin, ammonium persulfate and is dispersed in the quantum dot 101 between aforementioned two kinds of materials.The mass fraction of this epoxy resin is 10% ~ 15%, and the mass fraction of ammonium persulfate is 65% ~ 80%, and the mass fraction of quantum dot 101 is 10% ~ 20%.Described quantum dot 101 comprises red light quantum point and green light quantum point, and the mass ratio of this red light quantum point and green light quantum point is 1:1.
Described expansion light part 100 has relative both sides, and wherein side offers holding tank 103 in order to accommodating light source, and the surface of the opposite side relative with holding tank 103 is for expand light face 102.This expansion light face 102 is curved surface, spreads during this expansion light face 102 of light therethrough due to refraction, thus reaches the effect expanding light.
Understandable, the problem that the quantum dot light emitting efficiency caused for avoiding the infiltration of oxygen and/or aqueous vapor reduces, can encapsulate the encapsulant of one deck printing opacity on the expansion light face 102 expanding light part 100, sealing material can be low permeable macromolecule membrane or ultra-thin glass.
In the present embodiment, described expansion light part 100 out-of-shape (ginseng Fig. 1 and Fig. 3).Understandable, described expansion light part 100 can also be set as that having of other expands the shape of light effect, as taper, polyhedral etc. as required.
Please consult Fig. 2 further, a kind of luminaire 200 applying described expansion light part 100, it can be used as the lighting apparatus (such as flat light-emitting device), outdoor illumination equipment (such as street lamp, electric sign etc.) etc. of backlight module in display unit (such as liquid crystal display), display unit inside.This luminaire 200 comprises substrate 201, be electrically connected this substrate 201 and for providing at least one LED(light emitting diode of light) module 202, at least one expands light part 100, is electrically connected the control circuit (not shown) of substrate 201 and LED module 202.Each expands light part 100 and covers on a LED module 202, and LED module is placed in holding tank 103.This expansion light part 100 spreads for making light.This control circuit is power on/off for control LED module 202.The light that this LED module 202 sends is white light, this white light is in time expanding light part 100, the some blue light contained in this white light excites the red quantum point in expansion light part 100 and green light quantum point to produce ruddiness and green glow respectively, like this, the light launched via expansion light part 100 contains more ruddiness and green glow, thus further increases colour rendering and the colour gamut of light.
