High-color-rendering-index and high-luminous-efficiency fluorescence conversion composite material for laser illumination and preparation method thereof
The invention discloses a high-color-rendering-index and high-luminous-efficiency fluorescence conversion composite material for laser illumination and a preparation method thereof.The fluorescence conversion composite material is composed of lens-shaped fluorescent ceramic and a fluorescent silica gel layer coating the surface of the fluorescent ceramic, and the fluorescent ceramic is excited by blue exciting light to emit yellow-green light; the fluorescent silica gel layer is excited by the blue exciting light to emit red light; the preparation method comprises the following steps: preparing lens-shaped fluorescent ceramic by adopting a gel casting method, coating a red fluorescent silica gel layer on the surface of the lens-shaped fluorescent ceramic, and drying to obtain the fluorescence conversion composite material. The composite fluorescent material prepared by the invention realizes high-brightness white light emission under the excitation of a blue light LD chip with the wavelength of 455nm, the luminous efficiency is 190-260lm/W, the color rendering index is 90-96, and the composite fluorescent material is simple to prepare and easy for industrial production.
