    Abstract: The present disclosure is related to a fluorescent glass for a light emitting diode and a manufacturing method thereof. The fluorescent glass for the light emitting diode includes a glass powder and a fluorescent powder, wherein the glass powder and the fluorescent powder are mixed to form a fluorescent glass, the material for manufacturing the glass powder comprises silicon dioxide with 20 wt % to 37 wt %, diboron trioxide with 31 wt %-47 wt % and calcium oxide with 16 wt %˜35 wt %, and the material of the fluorescent powder is selected from one of Ce-YAG, LuAG, silicate, and nitrides/oxynitrides fluorescent powder. The fluorescent glass of the present disclosure is formed by mixing and sintering the glass powder and the fluorescent powder and has low sintering temperature, so as to avoid the deterioration of color of the fluorescent powder due to high temperature. Therefore, the fluorescent glass of the present disclosure has good transparency, and the light emitting diode applying this fluorescent glass has good lighting efficiency.

    Abstract: Provided is a lens module with an integrated structure, including a first lens and a second lens, a first substrate and a second substrate, an optical bonding layer, a first absorption layer and a second absorption layer, wherein the first absorption layer includes a copper complex, which is formed from a copper compound, a phosphonic acid represented by formula 1 herein, and at least one phosphorus-containing compound represented by formulas 2 to 4 herein. Due to the integrated structure, the lens module can be reduced in size. The manufacturing process is simplified because no assembly process is required. The lens module of the present disclosure exhibits high transmittance for visible light and low transmittance for near-infrared, showing an excellent near-infrared cut-off effect. In addition, while the incident light irradiates the lens module at different angles, the transmittance curve only is slightly shifted.
