Abstract

The invention relates to large-power blue light LED remote exciter lamp cover electrostatic spraying yellow fluorescent powdery paint. With the paint, yellow-converted composite white light can be emitted. The paint is characterized in that a thermo-set polyester resin transparent powdery paint finished product is processed by using a Fluent-type inner-graded jet mill, such that a composition of yellow fluorescent powder yellow-light-emitting powdery paint is synthesized by homogenization; the composition is extruded by using a double-screw extruder, and is crushed by using a high-speed crusher, such that a YAG yellow fluorescent powder yellow-light-emitting powdery paint finished product is obtained. With the paint, a formed yellow fluorescent powder coating has certain scraping resistance. When an LED lamp cover is packaged, defilming is prevented. Under the remote exciting of a blue light LED chip, the conversion rate of the yellow light emitted by the yellow fluorescent powder and the blue light is high, and a composite white light is gentle. Blue light LED chips of different qualities are adapted to YAG yellow fluorescent powders of different qualities, such that illumination devices of composite white light LED with different color temperatures, different color rendering indexes Ra and different luminous efficiencies 1m/w can be configured.
