In a preferred embodiment of the present invention, described basic unit and luminescent layer paper spare also comprise focus layer, and described focus layer is the coat of metal.
Another object of the present invention is to provide a kind of preparation method of the reflective membrane for LED light source, and concrete steps comprise:
(100), plant pearl: selecting suitable material is basic unit's film carrier, application of adhesive on the upper surface of described basic unit film carrier, and baking 1 to 2 minute in baking oven; Then make the lotus that becomes positively charged on described basic unit film carrier, make on glass microballoon with negative electrical charge, by the electric charge suction-operated, make glass microballoon evenly be distributed in closely basic unit's film carrier surperficial, and through pressing, a part of pressing of glass microballoon is entered in adhesive, then solidify through high-temperature baking, form beads formed film;
(200), be coated with wall: the one side that is implanted with glass microballoon at beads formed film applies acrylic resin, forms wall after solidifying;
(300), stopping off: armor coated on the wall surface;
(400), compound: last compound adhesive-layer and release layer form finished product.
In a preferred embodiment of the present invention, described acrylic resin comprises that mass percent is: acrylic acid 15% ~ 28%, ethyl acrylate 20% ~ 35%, methacrylic acid acid amides 5 ~ 8%.
In a preferred embodiment of the present invention, described basic unit is the PET film.
The invention has the beneficial effects as follows: the present invention is used for reflective membrane and the preparation method of LED light source, and the good life-span of reflecting effect is long.Concrete main adopt the special pearl method of planting, be that pearl is planted in the reflecting layer evenly tight, limited raising reflecting effect adopts a plurality of protective layers, and anti-aging is effective, and the life-span is long.
