The material is prepared from components as follows: 20-24 parts of aluminum, 2-3 parts of europium oxide, 2-4 parts of zirconium dioxide, 7-9 parts of calcium chloride, 5-8 parts of magnesium oxide, 0.05-0.1 parts of lithium fluoride, 4-8 parts of lanthanum oxide, 7-9 parts of barium acetate and 30-35 parts of an adhesive.

Description

technical field [0001] The invention relates to the technical field of fluorescent powder materials, in particular to an LED fluorescent powder adhesive. Background technique [0002] As a new type of green and environment-friendly solid-state lighting source, LED has become an inevitable trend of future development, and the era of new lighting sources represented by LED is increasingly showing its advantages. LED (Light Emitting Diode) is a solid semiconductor material that can convert electrical energy into visible light, and it can directly convert electrical energy into light energy. The inherent characteristics of LED determine that it is the most ideal light source at present, and it is widely used in photoelectric systems. Compared with other light sources, LED has energy saving, safety, long life, low energy consumption, less heat generation, high brightness, waterproof and shockproof , easy dimming, concentrated beam, easy maintenance and so on.
